Electric arc furnaces have a wide range of applications, and many metal production processes can be applied to electric arc furnaces.
According to the smelting form of the electrode, it can be divided into
Non-consumable electrode type electric arc furnace, which uses tungsten or graphite as electrodes. The electrode itself is not consumed or consumed very little during the smelting process.
Consumable electrode type electric arc furnace, which uses smelted metal as electrodes. The metal electrodes consume themselves while melting.
According to the control method of arc length, it can be divided into:
Constant arc voltage automatic control electric arc furnace.
Constant arc length automatic control electric arc furnace.
Droplet pulse automatic control electric arc furnace.
According to the working method, it can be divided into:
Cyclic operation type electric arc furnace, that is, each melting furnace is regarded as a cycle.
Continuous operation electric arc furnace, this type of electric arc furnace has two forms. One is a rotating furnace; the other is that two furnaces share a DC power supply, that is, after the smelting in one furnace is completed, the power supply is switched to the other furnace and the smelting of the next furnace is started immediately.
According to the structure of the furnace body, it can be divided into:
Stationary electric arc furnace.
Rotary electric arc furnace.
