Presentation of the equipment's characteristics

The silicon carbide reaction sintering furnace is mainly used for the reaction sintering of silicon carbide, cold-end welding of silicon-carbon rods, and metal powder preparation. The products produced by this equipment are widely used in military industry, lithium batteries, sanitary and architectural ceramics, aerospace, metallurgy, chemical industry, machinery, automobiles, and metal materials manufacturing. The equipment features a low failure rate and easy maintenance of the heating chamber. The material cart can move laterally to improve loading and unloading efficiency, and it is equipped with dual-stage pressure protection to ensure operational safety. An integrated rapid cooling system enhances production efficiency, while the vacuum system is equipped with a filtration and dust removal device to effectively control dust emissions.

processed samples

The silicon carbide reaction sintering furnace is primarily used for the reaction sintering of silicon carbide, silicon nitride-bonded silicon carbide, and dense silicon carbide. It is also suitable for high-temperature processing of carbon-carbon composites, carbon-ceramic materials, and cold-end welding of silicon-carbon rods. With nearly two decades of technological accumulation, the equipment has been upgraded to its third generation, making it more suitable for high-performance silicon carbide reaction sintering applications. The composite ceramic materials produced by this furnace are widely used in military applications, lithium battery new energy materials, semiconductors, sanitary and architectural ceramics, chemicals, electronics, and the automotive industry.

This equipment offers several technical advantages: it features an advanced heating structure that reduces failure rates and enhances stability; an optimized heating chamber design that improves energy efficiency by 20%, lowering operational costs; dual-stage pressure protection for enhanced safety and stability; an integrated rapid cooling system that increases production efficiency and shortens processing time; a vacuum system equipped with a high-efficiency filtration and dust removal device, extending vacuum system lifespan and improving durability; and a rigid monolithic frame structure, making the equipment more robust, reducing the risk of damage, and minimizing maintenance costs.
