Heating furnace uses brick of adiabatic heat preservation

Heating furnace uses material of basis of brick of adiabatic heat preservation to character clay pledges adiabatic brick and tall aluminium pledge heat preservation brick, use tall aluminium or clay to pledge firebrick build by laying bricks or stones builds adiabatic layer gently character, weight is light, heat preservation effect is good, can reduce principal part bearing, reduce heat energy loss, have the effect with energy-saving environmental protection.
　　

　Heating furnace uses fireproof data
Fireproof material is mixed by boiler setting, hearth in the applied body of heater of heating furnace body roof composition. Burner having end is installed in end wall of furnace a side, soaking still has a makings door on Duan Duan wall, have on another side end wall into makings door. Side wall is divided have furnace door and outside entering hole, heat paragraph side burner also is installed sometimes on side wall; Hearth of furnace of the type that choose steel runs slide by soaking bed and water-cooling or brick of slippery course of pottery and porcelain is comprised, the pace enters type furnace hearth criterion by fixed bridge (bottom) comprise into bridge with the pace.
　　
Customarily place calls hearth the solid hearth that the department shows firebrick build by laying bricks or stones is built or fireproof material makes errant body. Roof cent carries two kinds on the head for vault peace. Roof place suffers high temperature, air current erodes and the element such as thermal stress is affected, heat especially paragraph of forehead and soaking paragraph roof, mar more easily, it is the weak point of whole body of heater. Accordingly, the life of roof, represent the service life of heating furnace namely.
　　
Heating furnace uses firebrick
Body of heater of bricky build by laying bricks or stones uses the lining that adiabatic brick and firebrick build by laying bricks or stones build. Layer of furnace heat insulation uses brick of adiabatic heat preservation, use clay to pledge or brick of tall aluminous qualitative heat preservation, reach the material build by laying bricks or stones such as fireproof fiber felt to build. Ply is 113~300mm, layer of boiler setting job pledges with clay firebrick build by laying bricks or stones is built, ply is 230~400mm, place of hole of starting a hole is usable arch of bricky build by laying bricks or stones, spell step with different brick or build lid strip clay qualitative firebrick. If boiler setting needs higher to be in proper span place to install,tall aluminium pledges tension brick, arrive since boiler setting in case. In the meantime, heat bottom of Duan Lu wall needs to add thick, in order to increase its stability.
　　
Stick earthy and adiabatic brick
Brick of light qualitative clay is the small qualitative refractory products of AL2O3 content 30%-46% , belong to firebrick of light qualitative adiabatic heat preservation. Use clay grog or pledge argillaceous grog is mixed gently but model clay is main raw material, use combustible law production. Burden and water mix make but model pug or slop, with extrusion or pouring shape, dry hind in 1250 ℃ - in atmosphere of 1350 ℃ oxidation firing, in the high temperature environment that can be used at many degrees 1000 or so. Density of this product volume is 0.6-1.20g/cm3, compression intensity is 2.0-5.9mpa, thermal conductance is 0.25-0.5w/(m.k) .
　　

　　Brick of tall aluminous qualitative heat preservation

The Al2O3 content that brick of tall aluminous qualitative heat preservation controls for main raw material with aluminous alumina is not less than the adiabatic firebrick of 48 ％ . Basically use aluminous aluminous grog, combinative clay makes raw material, mix into is mixed into bond curium wood chip, to improve product performance, add the fine pink of stone of line of industrial alumina, corundum, silicon, cyanite, silica. Can make the product that gets above of Cm3 of ／ of bulk density 0.6-1.2g, 25 ℃ of ± of 0.25-0.45W/m.k(350 of heat conduction rate) . Al2O3 content and bulk density are different, high use temperature is different also, be in normally 1380 ℃ of 1250 ～ , some can amount to 1550 ℃ .
　　
Introduce here with brick of adiabatic heat preservation about heating furnace, hope to be helped somewhat to everybody, the material of heat preservation brick that flourish Cheng Naicai produces is qualitative all ready, have brick of clay, tall aluminium, Molaishi, light qualitative silica brick, light qualitative corundum, alumina hollow ball brick is waited a moment, the welcome seeks advice from a choose and buy, firebrick manufacturer is sold continuously, the price is reasonable, the welcome seeks advice.
