Specail Shape of High Alumina Brick

$High Quality Best Price High Alumina Insulated Refractory Fire Bricks$

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: Is there a big difference between two high alumina brick and one high alumina brick?: The difference between the two kinds of high alumina bricks is great. I perennial in Zhengzhou was responsible for the production and sale of colt refractories

Q: What are the high aluminum bricks made of?: The amount of refractory mud accounts for about 6% of the brick weight

Q: What are the grades of high alumina bricks?: High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick

Q: What's the difference between high alumina refractory bricks and high alumina refractory bricks?: The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.

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 characteristics of high alumina bricks?: A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined.

Q: Are there any differences between insulating bricks and refractory bricks?: Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.

Q: How to distinguish the good or bad of the high aluminum brick?: In the procurement of high alumina brick, the first color, high quality aluminum brick, brick surface smooth, yellow color pale, four sides equal, no broken angle, no cracks.

Q: How does the physicochemical index change when the high alumina brick is used at high temperature?: When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.
