General component is furnace of charcoal element calcination circumgyrate type and evaporate canister two kinds, furnace of charcoal element calcination is the hot project facility that has heat treatment for raw material with detached air. The fireproof material that charcoal burns furnace to use basically is tall aluminium fireproof and brick, clay brick, pouring makings.
Furnace of evaporate canister calcination is to make full use of the volatile material that charcoal pledges material is destroying the transgression in the process, furnace of additional share is gas, the air that changes hot cell warm-up with the course next mixes, burn in igneous path, to a kind of furnace that carbon material heats secondhand. The igneous path temperature in roast process is 1300~1380 ℃ , wen Da burning a mouth 1500 ℃ .
Calcination jar and the body of build by laying bricks or stones that fire use heat conduction property commonly softening point of good, to load the silica brick with great strength of machinery of tall, high temperature. Bottom of heat exchange room deserves to have checker brick, because high temperature bears bigger negative charge, undertook heating up exchange at the same time, because this goes to collect appliance to have the argillaceous brick with high softening point of good thermal stability, weight commonly, combustion mouth uses tall aluminous qualitative brick. Furnace of welding rod roast main effect is electrode of will unripe charcoal, charcoal piece, chemical block pole in close heat secondhand below air condition, make give birth to charcoal electrode, charcoal piece, chemistry block pole in close to heat secondhand in air and be become. Commonly used at much room bake. Because bake hearth bears go up the bear of block and firebrick, upside electrode box heats wall, block waits in mouth of igneous well box, combustion, still can bear the high temperature function that 1400 ℃ control and the influence that temperature changes, should use greater mechanical strength so, the argillaceous brick step that uses tall bate temperature and good thermal stability is built.
Build by laying bricks or stones of furnace of charcoal element roast builds those who use brick of light qualitative heat preservation to choose furnace of charcoal element roast, because departmental substation bears,high temperature differs, chooses fireproof material is endless also and same, be like mound of brick of ministry of hearth of airtight type roast, hole face brick bears body of upside build by laying bricks or stones and the weight that bake fire is tasted, igneous well gets the high temperature action of 1400 ℃ above, because this often uses mechanical strength tall, thermal stability is better sticky person brick build by laying bricks or stones builds furnace lid of furnace of roast of; airtight type, because produce shift of the need in the process, often use build by laying bricks or stones of brick of light qualitative heat preservation to build.
Of charcoal furnace general situation and firebrick the hot-working equipment that choosing charcoal to burn furnace is a charcoal material and a kind of air segregation. Heating action is the water portion in making carbon expects and volatile transgression, and generation bulk systole, true density increases wait for change, obtain better electric conduction, hot conductibility thereby, and fight oxidation, corrode. Carbolic element calcination uses heat of calcination of evaporate canister type normally, it by a lot of vertical small forge canister is comprised, every 4 are a group, cent becomes a certain number of groups. Furnace of calcination of evaporate canister type is to make full use of charcoal simple stuff is sent in the brandish of the transgression in calcination process gas, join one part to send Niu Lu inside igneous path gas, burn through igneous path, to a kind of furnace that carbon material heats secondhand, its blaze temperature can amount to 1300~1380 ℃ . Firing temperature is as high as 1500 ℃ , so furnace chamber and the chamber of a stove or furnace should experience the high temperature effect of 1300 ℃ above, also suffer outfit charcoal at the same time, the carbon material attrition to coal tub wall and concussion, of the gas when combustion erode, of seep and broken bits of salt of low melting point erode action. Be based on above reason, calcination can without lid and igneous road section, choose heat conduction property commonly the silica brick step with good strength of machinery of tall, high temperature builds temperature of good, to load. When burner temperature is high, with tall aluminous brick, the hearth that remain block uses red brick, light qualitative brick, stick firebrick, boiler setting part uses firebrick of red brick, clay, light qualitative firebrick.
Furnace of carbolic element calcination uses firebrick one, the following requirement should be satisfied before build by laying bricks or stones is built. (1) workshop internal energy prevents rain, prevent snow. (Frame of 2) body of heater and gripper shoe already were installed end, and reinspect qualification. (Of foundation of 3) flue concrete or steeliness platform finish, pass via examining. Firing fire of jar, combustion (include combustion opening) wait for place beforehand build by laying bricks or stones is built, choose next and combine different brick. 2, measure with perpendicular string staff. Before bricklaying, according to structural frame of body of heater and fundamental center line, the quantity gives clue of center of calcination canister, flue, make a picture respectively the flank at concrete foundation and gripper shoe, in order to facilitate the each part of body of build by laying bricks or stones of body of build by laying bricks or stones. Position of tall Cheng of body of build by laying bricks or stones of integral roast furnace is with elevation of surface of furnace frame gripper shoe fiducial. Bricky stone builds medium string staff, besides using the pillar all round brick, still need to raise a fine baton appropriately beside furnace, with body of control build by laying bricks or stones flat with elevation. 3, the build by laying bricks or stones of calcination shaft is built. Calcination body of heater is fire of calcination canister, combustion to from the cent on the structure (include combustion opening) , all sorts of passageways and outside the part such as the wall, and the data that uses according to place is furnace identity the bottom to stick on brick paragraph, intermediate silica brick brick of clay of Duan Heding ministry paragraph. 1. Rock-bottom clay brick. This paragraphs include: Block of brick of clay of calcination canister bottom, bottom warm-up air channel, of corresponding height outside body of build by laying bricks or stones piece. Before build by laying bricks or stones is built, should the central line of mouth of each the elevation of surface of microscope gripper shoe, flatness, makings, dimension, generally speaking, spread in gripper shoe surface above all 5? The asbestine with thick 8mm kind insulation board, spread the thin board with a large 0.5mm again, use as the slip layer of block. By firing F makings mouth begins bricklaying, next build by laying bricks or stones builds other part. After body of next makings mouth build by laying bricks or stones of calcination canister shape, to the central line inside canister of each groups of calcination (include calcination tin) undertook microscope. When build by laying bricks or stones builds the bricky layer that has warm-up air channel, answer to go along with Qing Dynasty along with build by laying bricks or stones, outside body of all sorts of build by laying bricks or stones of the wall are followed heat the corresponding brick layer inside coal tub ordinal build by laying bricks or stones is built, this includes firebrick of heat insolation of argillaceous brick, clay, red brick to wait. In-house, outside build by laying bricks or stones is built should draw a line, hold wall put oneself in another's position level off and perpendicular. 2. Part of intermediate silica brick. This part is the part with calcination the most important furnace, include share of silica brick calcination, each make a fire passageway, partition and all around wall. All buildings all introduce tile, the wall outside there also is what firebrick of heat insolation of argillaceous brick, clay, red brick forms outside silica brick stone. There still are all sorts of different passageway openings outside the brick wall of agglutinate. Body of silica brick build by laying bricks or stones uses the silicon of mix into water glass to pledge fireproof mud build by laying bricks or stones is built commonly. The concessional ply force that the brick cracks: Are calcination canister and igneous path built 1? 3 millimeter, live wire separates all around wall 2? 4 millimeter. Build by laying bricks or stones of 2.1 calcination canister is built. Forging coal tub is hollow rectangle column form, cross section is very little (1660mm × 360mm) , but height is very tall (some canister are as high as 8m) . The each brick inside the crock is comprise by special shaped brick. When calcination canister bricklaying, should first dry platoon check, become a center by two end build by laying bricks or stones again next. In construction, maintaining correctly of the appearance inside can without lid is a serious problem. When build by laying bricks or stones is built, should control its strictly sectional dimension and the central line span that assemble canister of calcination of adjacent of coal tub, photograph each. So every build by laying bricks or stones 1? Every other is about two layers to undertake single censoring. The furnace charge that when be being produced as a result of Ding Lu, uses is inferior, reason is in build by laying bricks or stones is creditable go up to must not have the wrong a tooth-like part of anything that expects with the platoon way is opposite, and arrange cannot exceed 2mm to wrong tine. After the silica brick step of calcination is good, want to undertake examining to verticality, its error cannot exceed 4mm, general every build by laying bricks or stones should undertake cable inlet bracket is checked on pace wearing. Additional, the flatness of block surface also should use rule examination at any time, make the bricky height of correspondence of every can without lid consistent. The coal tub wall of calcination is thinner, some have 80mm only thick. Leak to prevent gas change, every fire is built in build by laying bricks or stones before path lid, inside body of build by laying bricks or stones of coal tub wall, outside the brick seams Shi Ni to seal. What narrate forge canister to be able to install the hanger in can without lid to go up. Hanger is hooked by several reinforcing steel bar (composition of every long 1200~1500mm) , intermediate shop has board, furnace frame of have the aid of is worn, wear a beam, condole hangs hanger. Build thing as build by laying bricks or stones up, pick hook bound. The build by laying bricks or stones of every 2.2 firebox is built. The combustion fire path of roast furnace is located in roast furnace two side, by different brick composition, have 7~8 layer commonly. Before build by laying bricks or stones is built, issue a check to seam first, pull a line to be built by build by laying bricks or stones of one aspect of the matter next. When build by laying bricks or stones is built, often should check its sectional dimension, ensure the brick seams medium silt plentiful, hold put oneself in another's position of build by laying bricks or stones clean. Igneous path lid is built in build by laying bricks or stones before, what should remain on wall of path of thoroughly cleared fire and underside is silty reach sundry. Meanwhile, undertake checking to the flatness above body of the build by laying bricks or stones below cover board brick, use the law that draw a line to detect, error value is: The length in length cannot be more than 2mm, 4mm cannot exceed inside length. When build by laying bricks or stones builds brick, should keep clear of along with block content of bottom crowded oar, build by laying bricks or stones of every fire path is built after finishing, undertake checking to the elevation of face of cover board brick even. When bricky build by laying bricks or stones is built, should make sure mouth position, dimension, centre height accords with design requirement, control burner center line and space of igneous path center strictly to be apart from. 2.3 slip with expand seam. Upside of body of silica brick build by laying bricks or stones and below paragraph with argillaceous brick the contact is in, by the design the requirement stays have slip seam, slip seam should clean, level off. Between firing jar and bricky wall expand seam should prevent to jam, expand seam with fire path contact is in ram asbestine rope or fireproof fiber. Expand from next upgrade put apart between all sides of body of silica brick build by laying bricks or stones and brick of back wall mud seam, join asbestine in seam - silicon is able to bear or endure character fireclay filling. Other part expands seam should withhold by the design. 2.4 rear wall. Include firebrick of heat insolation of silica brick, clay, red brick to wait. Vent-pipe of etc of back wall, vent-pipe, vent-pipe, should stay on the brick wall of two sides clay of back wall establish air channel, notice to maintain design measure, notice cleanness, in blowhole change direction with before closing, want to be swept thoroughly, ensure its are expedite. 3. Part of argillaceous brick coping. This part includes system of build by laying bricks or stones of brick of clay of roast furnace upside, volatilize lane kind with body of other coping build by laying bricks or stones.
calcination canister aspirant makings mouth paragraph after chasing a layer to narrow, the bricky layer of working surface should stage build by laying bricks or stones builds even fault; If feed in raw material is sectional,did not produce change, should notice shaft is completely tall verticality. And, the center that enters makings mouth must agree with center of can without lid. Build by laying bricks or stones builds a build by laying bricks or stones to should be buried set firm. Bury buy the space between body of build by laying bricks or stones can use thick mud or asbestine mud stuff. Heat-insulation layer of blast furnace apical and fireproof and pouring makings, answer to undertake finishing after drying-out ends.
