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 are the specifications for bricks?

In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.

Q:What's the weight of the refractory bricks?

Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick, refractory insulating bricks (Rong Zhuzhuan);

Q:What is the content of free silica in the refractory bricks of high alumina bricks?

Refractory powders are not rich in free silica in varying degrees

Q:What are the high aluminum bricks made of?

The amount of refractory mud accounts for about 6% of the brick weight

Q:What's the price of high alumina refractory bricks?

Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.

Q:What is the standard classification of high alumina bricks and high alumina bricks?

High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System

Q:The difference between ordinary and diatomite brick refractory brick

Insulation products made from diatomaceous brick and porous diatomite. The main raw material is natural porous diatomite, and then a small amount of clay and fuel are added. The volume density of diatomite brick was 0.7g/cm3, compressive strength at room temperature is 1 ~ 2MPa, the coefficient of thermal conductivity at 400 C for 0.13 ~ 0.20W/ (M - K), the apparent porosity is greater than 70%, the coefficient of thermal expansion (1280 degrees) 0.9 x 10 - 6 DEG -1, refractoriness is greater than 1250 DEG C. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius.

Q:Is there a big difference between two high alumina brick and one high alumina brick?

According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.

Q:Which thermal shock stability of clay brick and high alumina brick is good?

Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products
