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's the jade stove for?
Is it a furnace made of corundum or a furnace for smelting corundum?Corundum brick stove is commonly used as a refractory material sintering furnace, can be fired refractoriness in refractories, below 1700 degrees such as brick, corundum brick, brick, alumina hollow ball and so on
Q:What are the main constituents of refractory bricks
High alumina refractory brick, high alumina refractory brick mineral composition for corundum, mullite and glass phase, its content depends on AL2O3/, SiO2 ratio, as well as the kind and amount of impurities, AL2O3 content can be divided into refractory brick grade. The raw materials are high alumina and sillimanite natural ore. They are also made of fused alumina, sintered alumina, synthetic mullite and calcined alumina in different proportions with clay. It is produced by sintering process. But the products are casting brick, brick, brick fused grain and unshaped refractory brick. High alumina refractory brick is widely used in iron and steel industry, non-ferrous metal industry and other industries.
Q:How much is a thermal brick?
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:Application of electric high temperature regulating valve?
Acid refractory with silicon oxide (SiO2) as the main ingredient, commonly used are silica brick and clay. Brick is siliceous products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste. The silica acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high, close to the fire, the volume does not shrink after repeated burning, or even a slight swelling, but the thermal shock stability. The brick is mainly used for thermal equipment of coke oven, glass furnace, furnace and other acidic silica brick, according to the physicochemical indexes and SiO2 content can be divided into several levels, mainly used in glass furnace and coke oven silica brick for two categories. Clay brick with refractory clay or bauxite clinker as main raw material, containing 30% to 46% of alumina, refractory degrees 1580 to 1770 DEG C, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used in refractory clay brick clay as main raw material is called common clay brick that made pyrojewel clinker as the main raw material, the porosity in the clay brick below 17% is called low porosity clay brick. Two kinds of clay bricks are divided into several grades according to the physical and chemical indexes. The price difference between the ordinary clay bricks and the low porosity clay bricks is great.
Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
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 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:What material is used in an iron smelting furnace?
Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on.
Q:What is the difference between corundum and high alumina?
The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.The difference between them lies in the content of alumina and the alumina refractory products with alumina content higher than 48%The content of Al2O3 is higher than 90%, which is called corundum brick.
