What industries can silicon nitride binding carbide materials be applied to?
Silicon nitride binding silicon carbide material is a new material. The main products include silicon nitride binding carbide radiation tubes, silicon nitride bonding silicon bricks, silicon nitrite bonding silicon carbide plates, etc. Silicon nitride and silicon carbide are compounds with strong covalent bonds and have similar physical and chemical properties. Silicon nitride combined with silicon carbide products has a series of excellent performance, such as high temperature resistance, corrosion resistance, wear resistance, erosion resistance, antioxidant, etc., non -ferrous metallurgy, steel metallurgy, powder metallurgy, chemical and other industries. Silicon nitride binding silicon carbide material is not soaked with non -ferrous metals and has good insulation performance. Therefore, it is widely used in the production of non -ferrous metals such as aluminum, copper, zinc, etc., especially the ideal material of the electrolytic slot side wall lining bricks.
The steel industry is the largest user of silicon nitride binding silicon carbide refractory materials. One of the important uses of silicon nitride bonding carbide refractory materials in the steelmaking industry is as a separation ring of horizontal casting. In the horizontal casting, the separation ring divides the steel fluid into the steel liquid area and the initial solidarity area of the steel liquid to play a role in separating the steel liquid-solid interface, which is important to maintain the stable starting point of the steel liquid solidification and the quality of the cast blank. effect. In addition, silicon nitride binding refractory materials can also be used in the lower part of the blast furnace furnace body, the waist waist and the air outlet area.
With the development of advanced non -color metallurgical technology, higher requirements have been put on the quality and performance of refractory materials used. SI3N4-SIC products do not wet with non-ferrous metal melts, and the performance is significantly better than oxide ceramics. In addition, SI3N4-SIC materials have the advantages of high heat-conducting, good thermal shock, anti-roll resistance, anti-metal steam erosion, etc., which are widely used in the melting furnaces of lead, zinc, aluminum, copper and other non-ferrous smelting industries.
The working temperature of the waste incineration furnace generally does not exceed 1400 ° C, but the working environment is relatively complicated. For example, during high temperature exercise, severe gas erosion, wear and garbage impact on the incineration furnace. Silicon nitride binding carbide refractory materials have good high temperature strength, abrasion resistance, acid -alkali corrosion, heat and shock resistance, etc., and have been widely used in waste incineration furnaces.
