The silicon carbide board is made of silicon carbide as the main raw material, adding some expansion agents and antioxidants, which can effectively increase the load softening temperature of the product and improve the anti-oxidation effect. It is a high-performance silicon carbide fired at high temperature by using SiO2 differential as the high-temperature combination phase Products.

Silicon carbide board has the advantages of high flexural strength at high temperature, high thermal shock stability, good thermal conductivity, wear resistance, and strong resistance to various atmospheres. Long-term use at high temperature does not deform and soften, and can maintain the high thermal conductivity inherent in silicon carbide. It is an ideal energy-saving material for various industrial kilns. Used in high-temperature kilns, as a flame-proof plate, it can significantly increase the furnace temperature, save energy and improve economic efficiency.

The main purpose of silicon carbide board is to make deoxidizer and alloy material for steel making. Phosphorus﹙P﹚ and sulfur﹙S﹚ are impurities that have a great influence on the quality of steel. When the silicon carbide plate contains more phosphorus, it is easy to pulverize ferrosilicon. When the furnace temperature improves, it can be fed and smelted. It is better to refining 45 ferrosilicon first, in order to quickly restore the furnace condition, and its operation is about the same as that of the newly opened furnace. The sulfur content in silica, because sulfur (S) and silicon (Si) in the smelting process form silicon sulfide, such as SiS, SiS2 and other compounds, these compounds are easily volatile and run away at high temperature, so the silica sulfur content is not required.

Features

1. High product strength: Under the condition of uniform specifications and long-term use without deformation, the thickness of the shed slab can maximize the utilization efficiency of the kiln and save energy.

2. Shed board has high density, smooth surface, and no slag when used.

3. Resistant to rapid cooling and rapid heat, it is not easy to crack when used.

4. Wide temperature range for firing: can be used in the range of 800-1400°C.

5. Great thermal conductivity, excellent corrosion resistance at high temperature, excellent wear resistance.

6. The anti-oxidation function is very good: it can adapt to the oxidizing atmosphere and reducing atmosphere firing of ceramics.

7. High temperature compressive strength and high flexural strength: the shed can be used on one side for a long time without turning over or deforming. Under normal operation and normal firing conditions, use turnover times of 500-1000 times or more.

Application

silicon carbide plate is mainly suitable for firing sanitary ceramics, building ceramic tiles, daily ceramics and electric porcelain in tunnel kilns, shuttle kilns and roller kilns at 1450°C. It is stable with high temperature strength, does not deform and does not break when used with columns Good thermal shock resistance, long service life, normal service life of more than 200 times. At the same time, due to the large thermal conductivity of silicon carbide kiln furniture and excellent heat transfer efficiency, the use of this material can save more than 30% of energy.
