What do tall aluminous brick and light qualitative tall aluminous brick have to differ?

Tall aluminous brick and light qualitative tall aluminous brick are common fireproof material, but they have clear distinction on composition, function and utility. It is the main differentia of tall aluminous brick and light qualitative tall aluminous brick below:


1.Brick of tall aluminium of composition and structure: Bases is alumina (Al₂O₃ ) , content is in commonly 48% above. Density is higher, the structure is compact, hole rate is low.


Light qualitative tall aluminous brick: Also be it is bases with alumina, but the vesicant that normally mix into enters certain amount or other light qualitative data, in order to reduce density. The structure is relatively loose, hole rate is higher, bulk density is inferior.
2.Brick of physical function tall aluminium: High strenth and wearability. Have taller fireproof degree, be in commonly above of 1750 ° C. Coefficient of thermal conductivity is taller, heat proof quality is opposite poorer.
Light qualitative tall aluminous brick: Density is low, it is normally between 0.6-1.2 G/cm³ . Have good heat preservation performance and inferior coefficient of thermal conductivity. Intensity is inferior, fight press and wear-resisting function is inferior to tall aluminous brick.
3.Heat up brick of function tall aluminium: Have admirable heatproof shake sex and high temperature strength. Can long-term below high temperature stability is used.
Light qualitative tall aluminous brick: Because hole rate is higher, thermal conductance is low, adiabatic effect is good. Thermal stability is poorer, in high temperature urgent cold urgent hot condition falls to appear easily crackle.
4.Brick of chemical function tall aluminium: The performance that fight broken bits is good, can counteractive acidity and alkalescent and slaggy erode. Apply to high temperature, tall caustic environment.
Light qualitative tall aluminous brick: The counteractive ability that erodes to soda acid is weaker. Basically use at heat insolation and heat preservation, do not suit to contact high temperature directly slaggy with strong corrosion environment.
5.Brick of utility tall aluminium: The liner of furnace of high temperature kiln that is used extensively at the industry such as metallurgy, building materials, chemical industry, electric power, wait like furnace of blast furnace, hot-blast stove, electric arc. Fit high temperature, high load capacity and strong corrosion environment.
Light qualitative tall aluminous brick: Basically use at the heat-insulation layer of furnace of high temperature kiln, the thermal insulation that is like liner of sirocco roof, heating furnace. Suit to need good heat proof quality but not tall to strength demand circumstance.
Tall aluminous brick and light qualitative tall aluminous brick have remarkable distinction on composition, function and utility. Density of tall aluminous brick tall, intensity is big, high temperature resistant, apply to high temperature environment of Yan Ke; Density of light qualitative tall aluminous brick low, heat proof quality is good, apply to the heat-insulation layer of furnace of high temperature kiln. According to specific applied requirement, the brick with right choice is planted ability develops its property adequately, assure manufacturing safety and efficiency.
