Reaction-bonded silicon carbide flame nozzles possess characteristics such as resistance to rapid cooling and heating, wear resistance, oxidation resistance, and high-temperature strength, making them suitable for various industrial kilns using gas or oil fuels. They effectively control the temperature balance inside the kiln and are ideal flame nozzles for tunnel kilns, shuttle kilns, and roller kilns, widely adopted by kiln companies and manufacturers both domestically and internationally. The flame nozzles feature high refractoriness, no slag dropping, no cracking, long service life, and easy replacement. They are widely used in gas-fired industrial furnaces such as tunnel kilns, shuttle kilns, and roller kilns. Introduction to Silicon Carbide Reaction-bonded silicon carbide (SiSiC) products exhibit high strength, high hardness, high wear resistance, high-temperature resistance, corrosion resistance, resistance to rapid cooling and heating, oxidation resistance, and excellent thermal shock resistance. They also possess fundamental properties such as good thermal conductivity and thermal stability. They are widely used in ceramic machinery, metallurgy, electronics, chemical industry, petroleum, steel, building materials, papermaking, mining, and other fields. Main Performance Characteristics High-temperature resistance and high strength. Below 1380°C, the high thermal conductivity and low thermal expansion of silicon carbide provide excellent thermal shock resistance. Additionally, it offers high strength and good resistance to creep and stress fracture. High hardness and wear resistance. Silicon carbide is one of the hardest materials, second only to diamond, capable of withstanding severe high wear and sliding wear. It is corrosion-resistant, oxidation-resistant, and erosion-resistant. The high density, low porosity, and chemical inertness of silicon carbide allow it to be used not only in high-temperature gas and liquid environments but also in strong acids and strong alkalis with oxidizing and corrosive atmospheres.
