Window data show that in November, the bulk raw material market was mainly stable, the benchmark price of silicon carbide fell again, and magnesia suppliers were planning to raise prices.
Many accidents have led to increased concerns about the impact of safety production, the impact of enviro...
Refractory bricks are a building material used in high-temperature environments and can withstand extremely high temperatures and chemical corrosion. In the steel industry, refractory bricks are widely used in the lining of high-temperature furnaces, converters, smelting furnaces, crucibles and othe...
Shanghai continues to be in "refrigerator mode" this week, with the lowest temperature in the urban area being -3℃ again...Hold on, 14℃ is coming by the middle of next week
How much snow is there today?
It can be seen with the naked eye, can be seen on car windows, and can be picked up on sleeves, b...
The market conditions for bulk raw materials were stable in the first half of November.
[Corundum] Bauxite control is relatively strict, raw materials are tight, brown corundum production enterprises have limited operating capacity, and market supply has decreased. However, in view of the light dema...
Oxidizing
The most widely used simple oxide is Al2O3. It has moderate thermal shock resistance, good stability to various atmospheres, and is a good electrical insulator at high temperatures.
• The strength of ceramics is affected by trace impurities and microstructural features. In general, po...
Refractory materials should be able to be used for a long time without damage under certain high temperature operating conditions. Generally, its performance is measured by the following technical indicators.
01
Refractory
When the refractory material is exposed to suffi...
Fire Clay Bricks are popular as building materials and widely used because they have several advantages. Some of the main benefits are listed below.
Strength: clay bricks have high compressive strength, which allows them to withstand large loads without breakage. This makes them suitable...
Heating furnace is a thermal equipment used to heat steel billets or small steel ingots when rolling or forging steel. The operating temperature is generally 1300~1400℃. With the large-scale and high-efficiency rolling mills, higher requirements have been put forward for heating furnaces. The develo...
China's refractory materials industry implements a regulatory system that combines competent authorities and industry associations and self-regulatory organizations. Among them, the industry competent department is the Ministry of Industry and Information Technology, which is responsible for macro m...
Refractory fiber is a fibrous refractory material and an efficient thermal insulation material. It has the characteristics of ordinary fibers (such as softness, high strength, etc.) and can be processed into various papers, belts, cords, felts, blankets, etc. It also has high temperature resistance,...
Ordinary clay refractory bricks have good thermal shock and are used for general kiln linings. The operating temperature is around 1250℃. If it is a low-gas clay brick, it can be used in glass kilns and some special kiln linings. The operating temperature is above 1350℃. If andalusite or cordierite...
Refractory castables are widely used in high-temperature fields mainly for their convenient construction performance and usability. Compared with refractory bricks of the same material, they greatly shorten the construction period, improve the construction site environment, increase maintenance effi...
