First, the melting furnace type: Crucible type resistance dumping melting furnace (for melting aluminum alloy, melting, heat preservation, dumping, etc.)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, resistance dumping furnace structure: resistance furnace consists of four major components: furnace lining, resistance heating belt, electronic control system, sputum, cylinder oil station tilting system.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 the resistance furnace: compared with the traditional furnace such as: diesel furnace series 坩 boiler due to oil exhaust, pyrotechnic pressure relief and other reasons, will cause pollution of the surrounding environment, the pyrotechnic pressure relief principle leads to its heat loss, The series of adverse factors such as low thermal efficiency utilization value, the emission of pyrotechnic pressure relief will cause excessive temperature and energy consumption in the surrounding area. 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.
