First, the melting furnace type: crucible type electric melting furnace (for melting aluminum alloy, there are functions of dissolution and heat preservation)

Second, the working principle of the electric furnace:

1. Overview: This furnace is suitable for die casting and non-ferrous metal smelting industries, such as aluminum, zinc, copper, magnesium alloy and other smelting. The solution and melting rate can be determined according to the needs. The control system can automatically adjust the functions of melting and holding power according to different conditions.

2, electric furnace structure: resistance furnace consists of four major components: furnace lining, resistance heating belt, electronic control system, crucible and so on.

3. Working principle: This furnace is a kind of equipment that heats the furnace and crucible after the heat is generated by the electric resistance belt, and then places the non-ferrous metal into the crucible pool for heating and melting.

4, the advantages of electric furnace: compared with the traditional furnace such as: diesel furnace series crucible boiler due to oil exhaust, pyrotechnic pressure relief and other reasons, will cause pollution of the surrounding environment, pyrotechnic pressure relief principle leads to its heat loss, thermal efficiency The use of low-value series of adverse factors, the emission of pyrotechnic pressure will produce excessive temperature and energy consumption. The furnace of the electric melting furnace is in a fully sealed state, and has the advantages of less heat loss, fast melting speed, environmental protection (smoke-free dust emission), and obvious energy saving.
