Classification and scope of use of high temperature electric furnace

High temperature electric furnace is mainly divided into the following categories:

1. Resistance furnace: Resistance furnace is a high-temperature electric heating equipment that uses resistance wire to generate heat. According to the different heating methods, resistance furnaces can be divided into box resistance furnaces, tube resistance furnaces, rotary drum resistance furnaces and so on. It is widely used in sintering, annealing, heat treatment, melting and other processes.

2. Induction heating furnace: Induction heating furnace is a high temperature electric heating equipment that uses electromagnetic induction to generate heat. It generates alternating electromagnetic fields through induction coils to generate eddy heat inside the workpiece. Induction heating furnace is mainly used in metal melting, heat treatment, casting and other processes.

3. Electric arc furnace: Electric arc furnace is a kind of high-temperature electric heating equipment that uses electric arc to produce high temperature. It produces high temperature through arc discharge and is used in metal smelting, alloy preparation and other processes.

4. Plasma furnace: Plasma furnace is a high-temperature electric heating equipment that uses plasma to produce high temperature. It produces plasma by ionizing gas, which is heated by the high temperature properties of plasma. Plasma furnace is mainly used in surface treatment, material modification and other processes.

The use of high temperature electric furnace mainly includes the following aspects:

1. Metallurgical industry: high temperature electric heating furnace can be used in metal smelting, heat treatment, casting and other processes in the metallurgical industry, such as steel, non-ferrous metals.

2. Ceramic industry: High temperature electric heating furnace can be used in sintering, heat treatment and other processes in the ceramic industry, such as ceramic products, ceramic materials, etc.

3. Glass industry: High temperature electric heating furnace can be used in glass melting, molding and other processes in the glass industry, such as glass products, glass fibers, etc.

4. Chemical industry: high temperature electric furnace can be used in high temperature reaction, distillation, drying and other processes in the chemical industry, such as chemical synthesis, fine chemical industry, etc.

In short, high temperature electric heating furnaces can provide heating, melting, heat treatment and other functions in high temperature environments in various industries to meet the needs of different processes.
