The commonly used clay brick in the whole process that ingot casting points to to molten steel introduces steel ingot model by disclose flourishing steel namely with argillaceous brick. Include brick of line of bucket flourishing steel and cast steel with the brick (amid has brick of place of brick of sleeve brick, head of a place of strategic importance, water, brick, model casting of tubal brick, management center runs brick, management center brick of brick, brick drifting steel, end drifting steel, ) of brick of background of model of steel ingot model. Earlier key is chosen but model law (16%-20%) production makes water share brick of ingot casting clay. Sale popularizes 20 new centuries to do a law to produce brick of clay of production ingot casting partly after 50 timeses. 2 kinds of production make means contrast, flow of workmanship of production of half dry method is little, character of handicraft tall is good, specifications is exact, production makes low cost, consequently, world each district all chooses half dry method to produce brick of clay of production ingot casting.
Brick drifting steel is the rectangular look that has varied norms type normally hollow clay brick. To reduce steel fluid liquidity the attrition obstruction in whole process avoids leakage steel, the regulation sheds the Kong Guangjie inside steel brick, exterior design is orderly, juncture handles close.
Brick drifting steel is build by laying bricks or stones of the application of the hollow corundum brick of brick of steel of cent of the join inside the tubal channel that uses photographic plate in ingot casting and steel ingot mould and relevant firebrick, alias Shang Daozhuan. Brick drifting steel is the rectangular look that has varied norms type normally hollow clay brick. To reduce steel fluid liquidity the attrition obstruction in whole process avoids leakage steel, the regulation sheds the Kong Guangjie inside steel brick, exterior design is orderly, juncture handles close.
Brick drifting steel is applied at steel of various alloy structure (include stainless steel board, each carbon steel) flat computer irrigates steel. Commodity is had fireproof degree tall, be able to bear or endure disintegrate sex is reached by force fight adhere sex strong. The exterior is orderly, drip essence of bright and clean, norms accurate, quality is excellent. The cast steel inside bag of manufacturing production steel brick of steel bag line, arc line brick, fire and did not burn brick of mouth of brick of head of a place of strategic importance, casting, brick and sleeve brick.
High quality raw material, the treatment craft of extraordinary makes commodity has good tall physico-chemical character, be able to bear or endure erode, not deformation, do not fall down.
Introduce
The commonly used clay brick in the whole process that ingot casting points to to molten steel introduces steel ingot model by disclose flourishing steel namely with argillaceous brick. Include brick of line of bucket flourishing steel and cast steel with the brick (amid has brick of place of brick of sleeve brick, head of a place of strategic importance, water, brick, model casting of tubal brick, management center runs brick, management center brick of brick, brick drifting steel, end drifting steel, ) of brick of background of model of steel ingot model.
Earlier key is chosen but model law (16%-20%) production makes water share brick of ingot casting clay. Sale popularizes 20 new centuries to do a law to produce brick of clay of production ingot casting partly after 50 timeses. 2 kinds of production make means contrast, flow of workmanship of production of half dry method is little, character of handicraft tall is good, specifications is exact, production makes low cost, consequently, world each district all chooses half dry method to produce brick of clay of production ingot casting.
Characteristic
Ingot casting uses argillaceous brick, in cast steel destroy in whole process go up should cause is to suffer tall to molten steel, slaggy organic chemistry is corroded and erode effect, reach its to spend the harm of leap, bricky action and character compromise the quality of steel instantly, return correlation to arrive production is safe.
Fill brick of steel tub line
Those who fill brick of line of steel tub clay is technical characteristic: Al2O3 36%-44% , fireproof spend 1690-1750 ℃ , load molten spends T0.6(0.2MPa)1370-1430 ℃ , the heavy change that burn a line (1400 ℃ , 2h)0%-0.3% , show hole to lead 18%-19% , normal temperature issues 29.4-39.2MPa of compression experiment compressive strength. Tall molten steel advances a barrel inside, bucket line suffers substantially erode and thermal shock effect and its stop to be mixed in the molten steel inside the bucket slaggy deposit to its organic chemistry action. Consequently, clay line brick should have low residual, compact the exterior specification that follows with essence of life, below tall fire gets comparing the hot physics performance with argillaceous normally high brick.
Sleeve brick
The physico-chemical character of sleeve brick: Al2O3≥40% , fireproof degree of more than 1710 ℃ , the heavy change that burn a line (1300 ℃ , 2h)+0.1%-1.3% , show hole to lead 15%-25% . Its characteristic is to have heat-resisting shock effect, coefficient of thermal conductivity is low, do not split in irrigating steel whole process, do not have a club.
Brick of head of a place of strategic importance and water place brick
Its are physico-chemical characteristic: Al2O3≥40% , ℃ of the fireproof ≥1710 that spend different, load molten spends T0.6(0.2MPa)≥1370 ℃ , show hole to lead 15%-23% . This brick is in the guttural position of ingot casting, the vortex that gets molten steel more is eroded, corrode the most terrible. Consequently, the biggest to its character regulation.
Shed steel brick
Spread the physico-chemical character of steel brick: Al2O3 36%-40% , fireproof spend 1690-1710 ℃ , the heavy change that burn a line (1350 ℃ , 2h)+0.1~-0.3% , show hole to lead 17%-25% , regulation of these 1 group of bricks has admirable heat-resisting shake sex. Consequently, operate the hole rate of handicraft is among 17%-25% . It is not quite good that hole leads sex of low heat-resisting shake, hole leads Gao Kang to corrode characteristic difference. A regulation has exact size. The handicraft with poor quality, leakage steel can be brought about in the fission in application, consequently character of brick of steel of thermal convection current has strict government. Machine craft
Brick of ingot casting clay chooses production of half dry method to make, treatment craft and argillaceous brick are same.
Brick of ingot casting clay has sincere brick, cement brick, square brick, annular brick. Sheet is chosen when figuration double-faced fill pressure, also can choose two sides to fill press professional facility. Treatment of punch mould, production, nitriding must have significant measure noncombatant duty, can press the base substrate that comes out to pass a test,examination,etc. . Figuration actuating pressure is 40-80MPa, base substrate cubage amounts to 2.10-2.33g/m3 relative to density. Great majority of base substrate of ingot casting clay is square steel tube, round steel tube, need to establish outfit or top outfit when fire, aspect ratio does not exceed base substrate battlements normally 900mm, prevent to get power too heavy and deformation. A place of strategic importance wants many sided bag to block when head brick and loading of kiln of water place brick, prevent instantly flame of lay a finger on creates rift.
