Energy-saving technology of industrial kilns In industrial production, the heat generated by the combustion of fuel is used, or the electrical energy is converted into heat energy, so as to buy thermal equipment for various processing processes such as smelting, heating, drying, sintering, cracking and distillation of workpieces or materials. It is called an industrial furnace.Common Failure and Maintenance of Vacuum Quenching Furnace Industrial kiln is mainly composed of furnace lining, furnace frame, heating device (such as combustion device, electric heating element), preheater, furnace pipeline, smoke exhaust system, furnace machinery and other parts.Requirements for deep carburizing on heat treatment equipment At present, industrial furnaces are widely used in all walks of life in the national economy, such as metallurgy, building materials, chemicals, light industry, food and ceramics. It has many varieties, high energy consumption and great influence, and is the key equipment for industrial heating. 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 labor conditions, and realizing civilized production.3Cr13 stainless steel spring vacuum high pressure gas quenching heat treatment
