How is brick of firebox heat preservation chosen?

How is brick of firebox heat preservation chosen? Small today make up arranged the relevant content about heat preservation brick for everybody, hope when to selecting heat preservation product to everybody, be helped somewhat.


Firebox is be built by firebrick build by laying bricks or stones and become, use argillaceous brick or build by laying bricks or stones of tall aluminous brick to build commonly. Two firebox bricklaying is measured about 120t left and right sides. Build by laying bricks or stones seams a requirement to be less than 2mm, the significant position such as vault all uses 701 plaster, hearth etc place uses general slop. In bricklaying process, because working surface is big, bricky amount is much, if one is in quality of short of bricklaying to ask (if the brick seams big, slop not full wait) , the gas of glow can penetrate from these weak point and change of wall of edge furnace casing is moved, from metallic furnace casing leakage of not exact point. Expand seam general edge firebox to grow an edge to leave 4, can cancel actually, because be burned easily also here,wear flat. Expand the problem basically leans body of build by laying bricks or stones external the filling such as ash of heat preservation brick, coal fines, so that amortize firebrick of body of build by laying bricks or stones expand or contract.
How is brick of firebox heat preservation chosen? Brick of firebox choice heat preservation is general principle: 1, combinative product function and use place characteristic. Be like what clearance sex works to should choose the material with small thermal capacity. 2, intensity of system of the safe use temperature of material, heat conduction, high temperature, chemical stability. 3, use life. 4, investment expenses upholds charge with what move.
What does heat preservation brick have? 1, brick of pearlite heat preservation is a kind of new-style building decorates material, it is with expanding pearlite comes loose expect for aggregate, join waterproof agent and binder to undertake making up, choose, pressurization shapes, the brick of adiabatic heat preservation that the working procedure such as stoving makes.
2, brick of argillaceous heat preservation calls clay qualitative adiabatic brick again is the Al₂O₃ content that controls for main raw material with saggar the adiabatic and refractory products that is 30%~48% . Its produce craft to use burn oneself out to add content law and bubble way. With saggar, float bead, saggar grog makes raw material, mix into is added bond and curium wood chip, classics burden, mix, shape, dry, firing, make so that bulk density is the product of 0.6~1.3g/cm3.
3, brick of tall aluminous heat preservation calls tall aluminium adiabatic brick again. Composition of brick of tall aluminous heat preservation basically is mixed by Molaishi the light qualitative fireproof material that vitreous photograph or corundum constitute jointly. Bulk density 0.4 ～ 1.35g/cm3. Porosity 66% ～ 73% , compression intensity 1 ～ 8MPa. Heatproof shake performance is better.
4, Molaishi gets together brick of light heat preservation is with agglomeration clay of alumina of Mo Laishi grog, industry, union is mixed float bead make up pug, classics machine presses figuration. Mo Laishi gets together because brick of light heat preservation is had fireproof stability of degree of tall, thermal shock good, coefficient of thermal conductivity is low and characteristic, come with it directly at present build by laying bricks or stones builds the kiln furnace liner such as shuttle type kiln, use is more and more extensive.
5, brick of heat insolation of diatomite heat preservation is to use natural and poriferous diatomite to be main raw material, join a few combinative clay and combustible, via mixing refine, shape, dry and firing the brick that working procedure makes different appearance. ℃ of 900~1000 of high use temperature, with in doing lukewarm thermal insulation.
Heat preservation brick is had reduce kiln furnace weight, decrease wall of small pit boiler setting, change kiln furnace structure, rise warm up speed, reduce the sources of energy to use up, improvement works condition, improve work efficiency, use extensively at metallurgy, chemical industry, electron, the furnace of high temperature kiln such as glass.
How is more chosen about brick of firebox heat preservation, welcome you to call flourish Cheng Naicai, flourish Cheng Naicai provides fireproof data construction of furnace of production, sale, kiln, transform, maintenance, be able to bear or endure material chooses instructor, wait for hot project facilities for smelt of furnace of high temperature kiln, utility boiler, metal, offer one-stop service.
