Q:What are the characteristics of high alumina bricks?
High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining. High R.U.L, low creep high alumina brick with high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials.
Q:How much is the bending temperature aluminum silicon carbide brick for torpedo car
High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
Q:What is the difference between fireclay bricks and high alumina refractory bricks?
High R.U.L, low creep high alumina brick [1] is using high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials. The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.
Q:The difference between light high alumina brick and heavy aluminum brick
Lightweight high alumina bricks, commonly called insulating refractory bricks, also known as insulating refractory bricks. First of all, literally, lightweight aluminum bricks and heavy aluminum bricks are very different in weight. Lightweight high alumina bricks, also called insulated high alumina bricks, are designed for insulation and heat preservation. In normal use, the utility model is not directly contacted with the furnace temperature, and is a refractory brick product which is close to the furnace wall and has the function of heat insulation and heat preservation.
Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
Because the hot air outlet of the top burning hot blast furnace is high, the installation requirement of the hot air manifold is high, and the requirement of the strength of the pillar structure is higher, so the rectangular arrangement of the hot blast stove is arranged. The top burning hot blast stove is located on the furnace top because of burner and hot air valve,Therefore, operation, maintenance and installation all require mechanization and automation. Also, because these water cooled valves are mounted with a high elevation,Therefore, the demand for cooling water supply pressure should be improved accordingly, the use of large top burning hot blast stove, the key lies in the design of high-power high-efficiency short flame burner. The top combustion hot blast furnace absorbs the advantages of internal combustion and external combustion hot blast stoves, and overcomes some of their shortcomings,Its structure can meet the requirements of modern blast furnace for high temperature, high pressure and large scale development,Combustion capacity, while meeting production requirements, has been successfully reduced by many devices,
Q:What is the difference between corundum and high alumina??
The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
Q:Difference between low creep high alumina brick and ordinary high alumina brick
The emphasis is on the physical and chemical indexes of low creep and high alumina bricks. The physical and chemical indexes of the high alumina bricks are different, too. They are DRL-1550And LZ-75 perform GB GB/T2988-2012
Q:What kind of material is the general metal case?
Ordinary computer chassis and the material itself does not produce high-energy radiation, only in the space environment of the computer is the external defense requirements, and in the space structure, the use of lead as protective materials, unbearable weight.
Q:What is the density of a super high alumina brick and what is the price?
Of course, the transaction price, please choose refractory brick manufacturer is better.
Q:Application characteristics of high alumina brick
Reheating line change. If the firing temperature of high alumina brick products is enough and the firing time is enough, the volume is stable, the change of the reheating line is small; on the contrary, the residual shrinkage of clay brick products is caused by recrystallization.
