In industrial production, use the heat generated by fuel combustion, or convert electrical energy into heat energy, so as to purchase thermal equipment for various processing techniques such as smelting, heating, drying, sintering, cracking and distillation of workpieces or materials, Known as industrial furnaces. Industrial kiln is mainly composed of furnace lining, furnace frame, heating device (such as combustion device, electric heating element), preheater, furnace front pipeline, smoke exhaust system, furnace machinery and other parts.Vacuum carburizing of aviation gear steel At present, industrial furnaces are widely used in all walks of life in the national economy, such as metallurgy, building materials, chemical industry, light industry, food and ceramics and other industries. It has many varieties, high energy consumption and great influence, and is the key equipment for industrial heating. Precision carburizing heat treatment of gears The development of its heating technology and the adoption of high-efficiency energy-saving technology have a great impact on improving product quality, reducing production costs, rationally utilizing energy, improving working conditions, and realizing civilized production.Influence of Reaction Sintering Process on Properties of Silicon Carbide Ceramics
