In order to maintain the good performance of the medium frequency induction melting furnace, extend the service life of the equipment, and improve the safety and reliability of equipment operation. Without considering the investment cost, it is very important to reduce energy costs.
The comprehensive use of the furnace is usually more economical. When the medium frequency induction melting furnace is still used, it is very reasonable to use a medium frequency induction melting furnace to store and buffer the molten metal in order to ensure that the medium frequency induction melting furnace can continuously output the molten metal, and it can store enough metal until it needs it.
The medium frequency induction melting furnace can be started at the best productivity the night before, and the metal it reserves can be used for one day, and the heat preservation during the day only consumes low power. Another mode of operation is to continuously melt and refine in a small coreless induction furnace, and use a larger medium frequency induction melting furnace to reserve all the molten metal required for casting during the day. This can minimize the size of the melting furnace and the total power of the equipment.
The most practical measures to solve the problem depend on the specific technical conditions. Edgerley (85) gives the example of a furnace that can be used 24 hours a day, 5 days a week, and still only achieve 50% utilization. It therefore advocates careful consideration of the maximum effect that the equipment layout (plant design) and technical conditions can provide in terms of energy efficiency. In all methods, the furnace can be most effectively operated by pouring, rapid charging and continuous opening and closing of the furnace cover in a properly positioned position. Hot metal can be directly recycled to any type of furnace. In this chapter, some typical medium frequency induction melting furnaces and induction furnace operating cost comparisons are given.
Induction billet furnaces can heat billets to temperatures ranging from room temperature to over 1200°C.
After the Slab is pulled out from the continuous casting machine,Surface temperature is 750 ~ 850℃.
The melting furnace mainly melting the steel, iron and metal. The equipment is mainly composed of power control cabinet and melting furnace body.
