Q:What refractory materials are adopted in each part of the blast furnace?

Bosh temperature reaches 1600~1650, high alumina brick, corundum brick or silicon carbide brick. The upper hearth tuyere zone near the temperature at 1700~2000 Deg. C, the use of sillimanite brick, corundum and silicon carbide refractory filler, Shi Mozhi. Bottom temperature at 1450~1500 Deg. C, the use of graphite bricks and microporous carbon brick, now also used corundum brick, Gang Yumo brick and synthetic mullite brick.

Q:What kind of fused corundum corundum brick should be used for each part of the glass furnace?

The compact microstructure of AZS33# zirconia corundum brick makes the bricks resistant to glass liquid corrosion, and it is difficult to produce stone or other defects in the glass kiln. It is the most widely used product in the glass furnace. It is mainly applied to the upper structure of the melting pool, the wall brick of the working pool and the paving brick, the material way, etc..

Q:Zirconium corundum 25 content and 40 content, how to distinguish in appearance?

The fused zirconia corundum brick is mainly made of fused zirconia and corundum. ZrO2-Al2O3-SiO2 three element system fused brick, containing Al2O3:40% to 50%, ZrO2:30% to 50%, SiO2:10% to 17%.From the point of view of data analysis, there is no radioactive substance in it, and it will not cause harm to the human body.

Q:What is the main component of corundum?

Corundum is the main component of Al2O3, often containing trace impurities such as Cr, Ti, Fe, V and so on.

Q:Which is good, glazed brick and whole cast glazed brick?

Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.

Q:What kind of refractory material will be used in the glass kiln?

It has the best resistance to high temperature E glass corrosion, its erosion basically does not cause pollution to the glass liquid, so it has become the first choice of E glass unit refractory bricks.Dense chromium oxide is formed by isostatic pressing. Its density is very high. The main technical indexes include Cr2O3 content >94%, porosity <15%, volume density >4.24g/cm3, and erosion loss only 1/10 of compact zirconia brick. Used in the E glass furnace unit kiln, directly contact high temperature molten glass melt, wall, melting parts, high temperature parts, pool bottom, main channel, pool wall and pool bottom, transition channel, pool wall, etc..

Q:What is the price of concrete self insulation bricks?

Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.

Q:What does refractory consist of?

Refractory materials can be divided into main raw materials and auxiliary raw materials according to their function in the production process of refractory materials.The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.

Q:What can zirconium sponge do for those industries?

Uses: aerospace, military, nuclear reactions, atomic energy, and metal superhard materials, the manufacture of bulletproof alloy steel, can also be used in the reactor uranium fuel coating alloy; zirconium at high temperatures easy to launch electronicProduct characteristics: zirconium metal has very strong corrosion resistance, ultra high hardness and strength

Q:What refractory materials are used in industrial furnaces?

Masonry parts using his cooperation because of the repair or overhaul time, labor, materials, fuel consumption is great. Some of the other, a stove overhaul, will inevitably affect the other parts of life. Therefore, the selection of materials should be thinking of various parts of masonry of life, the habit.
