Reaction-bonded silicon carbide Precautions for use?
Silicon carbide cymbals have the characteristics of high bulk density, high temperature resistance, heat transfer, acid and alkali corrosion resistance, and high high-temperature strength. The lifespan of silicon carbide is 3-5 times that of ordinary graphite. It is suitable for various powder sintering and metal smelting in the metallurgical, chemical, and glass industries. So, what are the precautions for using reaction-bonded silicon carbide?
Precautions for using reaction-bonded silicon carbide:
1. When using silicon carbide, usually do not fill it too full with melted substances to prevent heat from jumping out, allowing air to freely enter and exit for possible oxidation reactions.
2. The bottom of the silicon carbide plate is very small. Generally, it needs to be directly placed on a clay triangle with fire. The silicon carbide cylinder has an iron triangle frame and is placed at an angle. Experimental needs can be placed by oneself.
3. The heated silicon carbide gel cannot be immediately placed on a cold metal surface to avoid rapid cooling. It should not be immediately placed on a wooden surface to avoid burning the surface or causing a fire. The correct method is to cool it on an iron triangle or let it cool down slowly.
4. Reaction-bonded silicon carbide The main products include: beams, rods, flames, cold air pipes, thermocouple protection tubes, radiation tubes, desulfurization nozzles, wear-resistant linings, wear-resistant and corrosion-resistant impellers, sandblasting nozzles, sheds, silicon carbide, carbonized carbonization, silicon carbide production, bowls, switches, seals, and various external parts. This product has high strength, high wear resistance, high temperature resistance, cold resistance, heat resistance, acid and alkali corrosion resistance, heat conduction, heat shock resistance, high-temperature creep, and other properties and characteristics.
Reaction-bonded silicon carbide What are the advantages?
1. Energy saving: Reaction-bonded silicon carbide has good thermal conductivity and thermal stability, so the industrial output has reached about 30%. In particular, the use of mine internal discharge pipelines and heat exchange devices reduces heat loss by 20% and saves fuel by 30%. Its wear resistance is six to seven times that of ordinary materials.
2. Non-ferrous metal monograph: Reaction-bonded silicon carbide has good high-temperature performance and impact resistance, making it suitable for use as a heating material. It has high strength and good thermal conductivity and can be used as aluminum electrolytic cells, copper furnace linings, and thermocouple protection tubes.
3. Metallurgy and mineral processing industry: The hardness of reaction-bonded silicon carbide is second only to diamond. It has strong wear resistance and can be used as a good material for wear-resistant pipelines, impellers, rotors, etc.
4. Building ceramics and abrasive wheel industry: Utilizing the high heating coefficient and thermal strength of sintered silicon carbide, the production cycle is shortened, and thin plates are manufactured. This not only reduces production capacity but also improves vibration and product quality. This is a type of ceramic glaze.
