Build by laying bricks or stones of place of anxious furnace hearth builds technological process:
Brick of heat insolation of excel in of common clay brick is slip the armor plate of the layer
Build by laying bricks or stones of foundation of anxious furnace hearth builds the base that is complete furnace, although do not have exorbitant requirement, but cannot ignore, should adopt reliable measure, hearth make level, achieve and strive to exceed national standard and design rules requirement, create advantage for project of whole body of heater.
Hearth by common sticky go up brick and composition of brick of excel in heat insolation. Before build by laying bricks or stones is built, answer measure fundamental surface level, make a record, use cement mortar make level. Step is common when clay brick and brick of excel in heat insolation, in group construction, first step is common clay brick, hind brick of heat insolation of excel in of build by laying bricks or stones, requirement slop is full. When fundamental underside elevation is inferior, build by laying bricks or stones builds front row layer common sticky person brick level is seamed can use be the same as grade cement mortar with layer of fundamental make level. Mix with next spray pipe those who sweep tubal contact is common sticky on brick and brick of excel in heat insolation should be machined meticulously, brick of heat insolation of build by laying bricks or stones notices slop is full especially with exterior flatness, build by laying bricks or stones must be chased when adiabatic brick piece hit slop, subtle step is built, when brick of superstratum of build by laying bricks or stones and adiabatic brick, press certainly given elevation line, the wood that use 2m relies on the examination side feet edge build by laying bricks or stones. The control method of fundamental underside elevation is to falling spray pipe and after sweeping the picture on the canal to give bricky layer to control bricklaying of mark, hearth to end. The slop that should adhere to the surface is swept carefully clean. By the design laid slides layer. The armor plate of slip layer and petroleum pitch oilpaper should machine ahead of schedule had made. Petroleum pitch oilpaper cannot one-time shop is over, otherwise, the meeting when construction causes shift or damage, should let a store along with build by laying bricks or stones.
Regenerator (small flue) build by laying bricks or stones is built
Regenerator place build by laying bricks or stones builds a course:
Small flue of oilpaper of hearth petroleum pitch advocate small flue is swept by brick of line of small flue of partition of center of small flue of single wall of wall small flue and shop reach regenerator of baffle of grate of furnace of protective grate brick advocate wall regenerator is odd partition of wall regenerator center
Before small flue build by laying bricks or stones is built, check furnace head level in the round mark board and erect surveyor's pole, affirm without by accident hind, had spread the petroleum pitch oilpaper of place of wall of place build by laying bricks or stones first, when undertaking brick of front row layer does a check to seam; build by laying bricks or stones to build, mix furnace head first coal of front row layer is tracheal bricky step is good, check its with lever of horizontal staff guage the position is exact. Because brick of front row layer is located on slip layer, shift of easy occurrence position, brick seams a fault to move, slop of vertical lap seam is not full wait for a phenomenon, after reason lists layer brick build by laying bricks or stones to be over afore, need scrutiny, correct in time, ensure place of put down bottom is proper.
Brick of small flue line arrives in build by laying bricks or stones of small flue wall after requirement height undertake, line brick and advocate, bilge between single wall seam paper immediate step is built at inside, bilge the appropriate that seam paper cuts fluctuation into parts two paragraphs, wait with the brick tall, improve the flat rate that line brick level seams so, the line brick that build by laying bricks or stones is over has been propped up in time with wood pole. After line brick and bottom brick build by laying bricks or stones are over, sweep metope and underside clean, the sawdust on the shop, again build by laying bricks or stones builds grate brick.
It is crucial that build by laying bricks or stones of brick of grate of small flue furnace is built one annulus, the aperture of grate brick is to press hydromechanical principle, to make air current distributings even and of the design, its are arranged very strict. Because the diametical change of aperture is not big, machine production error effect plus firebrick, when consequently build by laying bricks or stones is built mix size easily, often because of this do poorly done work over again. Want to notice in construction: The position of air, gas regenerator, prevent grate brick wrong number or answer to draw the position of equipment brick date first go up in the wall, good according to control line control brick is seamed, examine carefully bricky date, do not get brick of promiscuous; grate lower slop should be followed along with build by laying bricks or stones blow clean, the bricky stage flatness of grate brick should use examination relying on feet at any time, with seamed feet T expands to should accord with design requirement between boiler setting, keep clean, after build by laying bricks or stones is over, should do check in the round, ensure without by accident hind, above spread baffle of wood of a 50mm. If pursue,1 is shown.
To make sure form of build by laying bricks or stones is exact, check doing a platoon is seamed, line build by laying bricks or stones is hanged in furnace head the brick that the beard before brick of wall of front row piece grows entire wall is placed beforehand entirely, tone choosing, make sure ash is seamed even, requirement plaster is certain and full, want to accomplish dozen of full plaster, squeeze a slop when crowded oar. Take strict precautions against dozen of ash the beautiful face that when build by laying bricks or stones is built, causes and sky are seamed, want to often turn over the brick with good step, check its slop by oneself full extent improves operation method to affirm full extent is more than slop ceaselessly 95% when, just allow continue bricklaying. Build by laying bricks or stones builds slop consistency to answer moderate, construction performance is good, the slop when build by laying bricks or stones builds gas canal brick should is stained with, touch solid, above can be touched twice when wanting. Chase a layer even piece set person specially assigned for a task to tick off seam. Great strength should fall to tick off severe Gou Man more all round tubal brick especially.
Regenerator is waste gas and air or gas the place that has heating up exchange, wall body brick seams requirement plaster full, close, leak in order to prevent gas flee hither and thither. If regenerator wall is lax close when, rise gas if flow into regenerator, not only gas loss is big, and local combustion phenomenon can produce in regenerator, serious when the checker brick that burn frit, make waste gas valve is out of shape. Consequently, should notice parallel is seamed at the perpendicular brick of metope, the regenerator in be like anxious furnace of room of some 6m char advocate wall 3818 with 3826 between (the perpendicular brick of 2) seeing a picture is seamed, because cannot squeeze an oar, easy generation is seamed for nothing. Two sides is used to hit grey Fabingjia to be ticked off by force in answering to be built in build by laying bricks or stones to this kind of circumstance seam.
Rubber plectrum should be used when build by laying bricks or stones builds gas canal brick, unplug rubber child insert lower level coal inside tracheal brick, next gas canal bricks hit slop on, unplug child lever is right providing opening, lifted handle shows a tube above the brick, good bricky build by laying bricks or stones. Put forward rubber to unplug child, make squeeze the slop that go out to be taken entirely. After build by laying bricks or stones of gas canal brick is over, the surface of aperture is built prevent protecting cover, prevent sundry fall, maintain the cleanness inside the canal.
The course is built in build by laying bricks or stones in, the hole that often should use the flatness that relies on feet and metope of adjustable feet examination and regenerator is wide. The attention observes every vertical lap seam to whether go up point-blank in, avoid to swim Ding Zou is seamed. After every loop build by laying bricks or stones is over, to regenerator the wall undertakes overall level is measured, control the level of body of heater effectively.
Demand of elevation of regenerator wall coping is higher, especially requirement of elevation of photograph adjacent wall is more strict, it is 3mm only, achieving all through the ages of this quality standard is a difficult problem that anxious furnace build by laying bricks or stones builds staff, its prime cause is advocate texture of wall, single wall differs completely, advocate wall structure is complex, by a variety of model brick composition, when build by laying bricks or stones is built raise level easily, single wall structure is simpler, bricky name is single, when build by laying bricks or stones is built often on the low side. Appear to avoid this quality common fault, should take step: It is to strengthen build by laying bricks or stones to build a process to examine strength, use every loop elevation to check a result, discover a problem in time, the level that increases every brick seams ply, the elevation; that satisfies appearance of substance of build by laying bricks or stones gradually 2 it is to use the single wall brick with the dimension big error that the examination comes out to come drive up elevation. Should not use the method that in regenerator upside a few bricks increase a brick to seam centrally to solve the problem of elevation.
