Q:What is the difference between corundum and high alumina?

The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.

Q:What is the blast furnace ceramic cup called by the refractory factory?

The peak of new materials in various coal, metallurgy, mines, ports, electricity, building materials and military industry, a lot of workpiece and affect production equipment due to wear, wear resistant materials although rarely cause disasters metal workpiece disaster, but the resulting economic loss is immeasurable.

Q:How to improve the induction furnace campaign, from the promotion of refractory life start

According to the use of atmosphere, choose the appropriate spraying materials, such as infrared radiation paint

Q:What is the main component of corundum?

The name of corundum originates from India and is the name of mineralogy. There are three main variants of corundum Al2O3, which are alpha -Al2O3, beta -Al2O3 and gamma -Al2O3 respectively. Corundum is second only to diamond.

Q:How much is a refractory brick?

This question is too general, refractory bricks according to the use of the environment and industry, there are a variety of materials, a variety of specifications, prices vary greatly.

Q:What material is used in an iron smelting furnace?

In fact, refractory refractory ah is special ceramic frequently used AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials.

Q:What are the main constituents of refractory bricks?

Clay brick and clay brick are mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and square quartz and quartz (up to 30%). Usually with hard clay as raw material, pre calcined mature material, and then with soft clay, semi dry or plastic molding, the temperature at 1300~1400 C fired clay brick products. Can also be added a small amount of water, glass, cement and other binders to make non burning products and amorphous materials. It is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.

Q:What equipment is used for producing diamond blanks? How much is the investment?

Plus all the cables fifty thousand. Steel 10000 yuan. Corundum bricks; insulating bricks; clay bricks, these three require more than ten thousand. The electrode is about one hundred thousand. It's just an investment in an electric furnace. Together with the rear section processing and raw materials need hundreds of thousands of.

Q:What can zirconium sponge do for those industries?

Zirconium metal, also known as sponge zirconium, silver gray metal, the appearance of steel, shiny; melting point 1852 points, sub points, boiling point 4377 density 6.49. Zirconium is easy to absorb hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen; at 1000 DEG C oxygen dissolved in zirconium can make its volume increase significantly. Zirconium is relatively stable in the air; powder zirconium is easy to burn; fine zirconium wires can be ignited by matches; at high temperatures they can be combined directly with dissolved oxygen, nitrogen and hydrogen.

Q:Which is faster for heat transfer between corundum bricks and high alumina bricks?

For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
