- 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.
- 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:How much is a refractory brick?
- There are many kinds of refractory bricks, you have to look at what is material, the material is not the same, the price is not the same, clay brick is the cheapest, probably hundreds of dollars a ton, and corundum brick a ton of several money, silicon carbide, silicon nitride, and more expensive. And this thing is generally on t sell, the price is by a single block after conversion.
- Q:What are the refractory materials?
- Not a good answer. You can sort out, such as: neutral, alkaline, acid refractory. Different kinds, of course, raw materials are different.For example: MgO-C brick basic refractories: magnesia (fused, high purity graphite) + + + phenolic resin additives (silica fume or aluminum or silicon carbide or high temperature asphalt) etc..
- Q:What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
- Cast brick and clay brick masonry contact, eutectic phenomenon will occur at 1300 degrees Celsius, the selection of refractory materials, should avoid eutectic phenomenon serious two kinds of refractory materials such as brick masonry contact, in the following cast brick, the most vulnerable to erosion fused zirconium corundum brick.
- Q:Can the fire clay be reused?
- According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.
- Q:What are the main constituents of refractory bricks?
- Brick, refractory brick is containing more than SiO293%, is the main varieties of acid resistant brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.
- 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?
- The working conditions of industrial furnaces should first be investigated thoroughly, and the primary and non essential factors affecting the construction of furnace materials shall be analyzed. Focus on thinking, the temperature change condition, temperature bump slag properties, furnace atmosphere, heat insulation, impact wear and other special requirements, to ensure the quality of the life and product.
- Q:What kind of rock is corundum produced?
- If Ti4+ and Fe2+ containing a small amount of blue, a sapphire; containing six symmetrically distributed acicular rutile or other inclusions in some crystals, can produce six star awn, known as star ruby or sapphire stars, are precious stones. Corundum is vitreous luster with no cleavage, but cracks occur because of the presence of poly twin crystals that are often formed by the base or face of a face. Specific gravity 3.98. Of relatively low silicate igneous and metamorphic rocks and common in alluvial deposits. The U.S. state of North Carolina and Georgia, Russia's Ural mountains, South Africa as the main origin of the transvaal.
