How to Correctly Choose the Medium Frequency Induction Melting Furnace?

by Luoyang Judian Professional Steel Casting and Rolling Equipment M

The medium frequency induction melting furnace has fast heating speed and high efficiency, less burning loss, less stuffy heat loss, and relatively low workshop temperature. It has remarkable effects in reducing smoke and dust, saving energy, increasing productivity, improving working conditions, reducing labor intensity, and purifying the workshop environment. When choosing a medium frequency melting furnace, foundry enterprises should use transformer capacity, output requirements, investment quota, etc., and pay attention to the following items when purchasing equipment.

Electricity conditions for medium frequency induction melting furnace

Medium frequency induction melting transformer capacity

At present, for the SCR full-bridge parallel inverter intermediate frequency power supply commonly used in the industry, the numerical relationship between the transformer capacity and the value of the power supply is the value of the transformer capacity = the value of the power supply x 1.2. The transformer is a rectifier transformer. In order to reduce the interference of harmonics, it should be dedicated to the machine as much as possible, that is, one intermediate frequency power supply is equipped with one rectifier transformer.

Incoming line voltage of medium frequency induction melting furnace

For the intermediate frequency power supply below 1000KW, a three-phase five-wire system 380V, 50HZ industrial power is generally used, with a 6-pulse single rectification intermediate frequency power supply; for intermediate frequency power supply above 1000KWY, the focus is on using 660V incoming line voltage and 12-pulse double rectification intermediate frequency power supply.

Capacity requirements

According to the weight of a single piece and the weight of molten iron required for each working day, the capacity of the medium frequency induction melting furnace can be determined. Then determine the power and frequency of the intermediate frequency power supply.

Selection of structure

According to industry habits, the aluminum alloy structure supplies a melting furnace with a reducer as the tilting method is commonly known as an aluminum shell furnace. The steel structure induction melting furnace with a hydraulic cylinder as the tilting method is commonly known as a steel shell furnace.

Technical Strength

Formal manufacturers have invested a lot of manpower and material resources in the research of advanced technology, with advanced and complete equipment and exquisite technology, and they have different reflections in terms of melting speed, power consumption, and equipment failure. Many manufacturers do not have the conditions for in-factory debugging, so the cost is naturally lower. The assembly and debugging process has a great impact on the quality. Different manufacturers, different processes, and different prices also result in different quality.

After-sales service

Good after-sales service is the guarantee of equipment quality. It is inevitable that mechanical and electrical products fail, which requires good after-sales service. Regular manufacturers have sufficient technical personnel and capabilities to guarantee after-sales service. The intermediate frequency induction melting furnace has undergone repeated static and dynamic debugging before leaving the factory and has a one-year warranty period. During this period, any equipment failure caused by non-human responsibility will be borne by the manufacturer.
