Industrial furnace is an industrial heating equipment that heats materials and makes them change physically and chemically. Furnace and kiln are obviously distinguished from each other, but the significance is slightly different. In the mechanical industry, the heat treatment equipment usually used to complete the heating, melting, heat treatment and other heat processing technologies of various workpieces or data is called furnace, while the heating equipment used in silicate industry is called kiln. Industrial furnaces are often referred to as "industrial furnaces".

With the requirements of different production technologies, industrial furnaces are constructed in various ways, but generally speaking, the following requirements should be met:

1) The heating rate is fast and the yield per unit area is high.

2) The furnace temperature and temperature are easy to control and the product quality is good.

3) Low unit power consumption and high thermal efficiency.

4) The utility model has the advantages of simple structure, low cost, long service life and convenient repair.

5) Simple operation, high degree of mechanization and automation, less environmental pollution and good working conditions.
