Aluminum alloy resistance dumping furnace
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.

Third, the composition of the resistance dumping equipment:
1. Composition of electronic control: The panel of the control cabinet includes ammeter, voltmeter, main control intelligent instrument and push button switch, etc. The air switch, AC contactor, thyristor, fast fuse, intermediate relay, circuit breaker and Composition of other electrical components. Electrical components and the like are all "premium" products.
2, the composition of the furnace: from the furnace shell, furnace lining, silicon carbide crucible, heating components (resistance wire), two sets of thermocouples (furnace, each in the pool).
3. The hydraulic dumping system is designed to pour two cylinders of 10T or more, oil pressure station, circulating high pressure oil pipe, etc. The hydraulic dumping control is manual operation, so that problems can be dealt with in time during the dumping process, the dumping speed can be adjusted, and the tilting angle is 90 degrees.
Fourth, the safety performance of the equipment:
1. This furnace is equipped with safety devices such as current overload and furnace temperature limit protection, as well as tank leakage alarm. According to the national standard design specification, the cable load is matched with the load, and the grounding is well, there is absolutely no safety hazard.
2, the outside of the furnace is not hot to hurt people (international standard 55 ° C), the furnace lining uses multi-layer high-efficiency insulation insulation material, has a good thermal insulation and insulation effect. During the operation of the melting furnace, the furnace temperature is uniform, the furnace temperature is stable, and the fluctuation range is small.
