The main structure of industrial furnace lining is in structure of industrial furnace body of heater, the system of build by laying bricks or stones that commonly used firebrick builds basically is used at wall body, roof, hearth and conduit. 1 fireproof and pouring makings is fireproof and pouring expect the main material intrigue that regards body of heater as the structure, the village inside the side wall that is used at structure of body of heater, roof, conduit, outside wrap up wait for obtain employment layer. Also use at obtain employment layer and furnace steel structure (like furnace casing) the heat-insulation layer between. From apparently look, fireproof and plastic might as well the function that supersedes firebrick on the main body structure of all sorts of industry furnace. But in applying actually, before making determination, still need to study the following and unusual situation. The type of 1) furnace and methodological: ? Does live abroad Ge block up to shout especially from Qiang of β reason: of structure of ?) furnace? Does emperor of caries of Xi of ず of ┕ of Zhu Huang of of dizzy of ゲ affectedly sweet dumpling owe collection of Ti inclined N to write down mulberry eunuch to fall mother be favored with group bald a bit is cut down pure Bao taken?
Design of style of build by laying bricks or stones of lining of industry of design industry lining, expand seaming structure of system of build by laying bricks or stones of lining of reservation and industry of configuration level assessment to design is skill of end furnace talent the evidence book to lining structure, it is the crucial step of set technology target. Here, above all, it is the structure of system of lining build by laying bricks or stones of main skill with fireproof skill. Structure of system of lining build by laying bricks or stones designs structure of system of build by laying bricks or stones of industrial furnace lining to use fireproof skill. In lining design process, always need to note the following respects: (1) suits furnace dimension. This is the manufacturing technology place that industrial furnace serves is specific, furnace dimension succumbs at craft premise, install full hall design. Furnace dimension is the basic premise of technology of industrial furnace production, lining dimension is direct the production that affects all craft. (2) stable structural method. In view of the special purpose of industrial furnace, lining is bosseyed normally heat. Be in condition of such zenithal difference in temperature for a long time when lining, perhaps turn melt into the layer in hot side when, lining structure can get very big training. Accordingly, the stability of lining structure is the crucial index that lining designs.
The choice of fireproof material is choosing industrial furnace liner when fireproof material, we can encounter two main problems: ① comes to what build by laying bricks or stones builds industrial furnace with what kind of fireproof material and grade each place; Whether does the origin of these ② material have assure, the price is cheap. Specific for, should consider the following matter. (The working requirement of 1) industry furnace should investigate furnace deep above all the working requirement of each place, those who analyse attaint to build furnace material is main with secondary consideration. The atmosphere inside property of change of key consideration furnace temperature, furnace temperature, slag, furnace, concussion wears away, conduct heat wait for special requirement, in order to assure the service life of furnace and product quality. If choose fireproof material according to furnace temperature, can consult as follows commonly. Lukewarm resistor furnace is brick of heat preservation of light qualitative saggar, fireproof in 1000 ℃ fiber, bleach bead brick; Fireproof and brick of saggar of heating furnace of 1300 ℃ fuel, tall aluminous brick, silica brick, carbonization silica brick, pouring fireproof and makings, plastic; 1100 ℃ heat treatment furnace is saggar brick, fireproof fiber; Brick of saggar of bath furnace of salt of 1300 ℃ high temperature, tall aluminous brick, zirconium bath furnace of salt of 300 ℃ high temperature; Furnace of resistor of 1400 ℃ high temperature pledges brick of brick of light qualitative saggar, light qualitative tall aluminium, gently brick of alumina brick, light qualitative saggar; Alumina of molybdenum silk furnace brick, corundum brick, carborundum brick, alumina is hollow ball product 1650 ℃ ; Brick of saggar of 1650 ℃ cupola, carborundum brick, dolomite brick, carbon brick, black lead brick; Fireproof and brick of brick of tall aluminium of furnace of 1700 ℃ electric arc, silica brick, magnesia brick, magnalium, magnesian chromic brick, dolomite brick, carbon brick, pouring makings; Silicon of furnace of 1700 ℃ induction is arenaceous, magnesia, tall aluminous zirconium is arenaceous, arenaceous; (2) the function that the high temperature performance characteristics of fireproof material should master all sorts of fireproof material, especially high temperature performance characteristics. Produce its advantage adequately, overcome body of furnace structure, build by laying bricks or stones and maintenance weakness. (3) because furnace is medium,heavy repair, body of build by laying bricks or stones the service life of each place is very great, time-consuming, material and fuel. In addition, furnace is certain the demolish and maintains inevitable meeting to affect other position service life of place. Accordingly, when choosing material, should body of mature build by laying bricks or stones the service life of each place, make its suit each other. (4) be in economically when material of whether logical choice, should undertake technical economy is analysed. Below the premise that satisfies furnace work requirement in technical index, answer to use the fireproof data with low price as far as possible, is not high-grade product. The consideration is OK oneself are made (if irrigate,build fireproof concrete) , use local data as far as possible, repair trash.
The energy-saving measure of industrial furnace. Energy-saving the measurement that must have science and check a method quite. At present accepted test method is hot balance test. The hot project that carries industrial furnace is measured, the hot project process that understands Anhui industry furnace in the round, the analysis diagnoses the patient's condition of heating furnace, find out its pathogeny, undertake energy-saving technical reformation, improve the thermal efficiency of heating furnace further, reduce onefold use up, obtain heating furnace to run the parameter of economic specifications index, analyse the moving case of heating furnace, adjust the operating mode of heating furnace in time, make its achieve optimal moving status, find energy-saving efficient way and way thereby.
