Silicon Carbide Kiln Shelves Sic Plate
Silicon carbide plate is suitable for all kinds of daily-use porcelain, art porcelain, sanitary porcelain, magnetic materials, building pottery, grinding wheel and other kilns. It can also be used as lining material and tank material in powder metallurgy industry in various industrial kilns such as kiln, gas and fuel oil.
Description
Product details:
Oxide bonded silicon carbide kiln furniture is made of high-quality silicon carbide as raw material, adding binder, forming under high pressure, and sintering at high temperature. Oxide bonded silicon carbide kiln furniture has a small expansion coefficient, good thermal conductivity, oxidation resistance, high temperature resistance, corrosion resistance, wear resistance, and long service life, which can greatly reduce the loading ratio of kiln furniture and fired products, and can achieve rapid firing It has a significant energy saving effect.
Product Feature :
1. Good anti-oxidation performance: it can adapt to the oxidizing atmosphere and reducing atmosphere firing of ceramics. Under normal operation and normal firing conditions, the number of use turnover is more than 500-1000 times;
2. High temperature compressive and flexural strength: the shed board can be used on one side for a long time without turning over and deforming;
3. It has good resistance to rapid cooling and rapid heating, and is not easy to crack when used;
4. The shed board has high density, smooth surface and no slag drop during use;
5. Wide temperature range for firing: it can be used in the range of 800-1400°C;
6. Great thermal conductivity, excellent high temperature corrosion resistance and excellent wear resistance;
7. High product strength: under the premise of the same specification and ensuring long-term use without deformation, the thickness of the shed plate is thin, which can maximize the utilization efficiency of the kiln and save energy.
Product Application:
Silicon carbide plates are widely used in daily ceramics, sanitary ware, electric porcelain, magnetic materials and grinding wheels and other industries.
