What is steelmaking in an intermediate frequency furnace?

“Scrap is melted through an intermediate frequency furnace, and then refined to continuous casting” is called a short process. The short process does not require complex iron pre-systems and blast furnace iron making. Therefore, the process is simple, the investment is low, and the construction period is short. However, the short-process production scale is relatively small, the range of production varieties is relatively narrow, and the production cost is relatively high. At the same time, it is restricted by the supply of scrap steel.

Short process

The production process of a small steel plant centered on the intermediate frequency furnace steelmaking process. The recovered steel scrap is crushed, sorted and processed, and then preheated into the intermediate frequency furnace. The intermediate frequency furnace melts the scrap, removes impurities (such as phosphorus and sulfur), and then taps the steel, and then obtains qualified molten steel through secondary refining. It is solidified and formed by continuous casting to become a steel billet, which is transformed into a steel material after a rolling process.
