Various application trends require different heating methods, so induction heating can be divided into four main types:
The first type is forging penetration heating, which includes low-frequency and long-cycle forgings, die forgings and annealing heating, which is described in Chapter 2. This chapter discusses other uses of induction heating, such as medium-frequency and high-frequency brazing, brazing, pipe welding, and container heating, semiconductor production, etc.; Chapter 5 discusses some special requirements for low-frequency and medium-frequency melting, and also involves some process issues of modern induction furnaces.
How Does an Induction Furnace Work?
An induction furnace is an energy-efficient, clean-melting furnace used to melt all type of metals such as steel, iron, copper, zinc and aluminum.
Because an induction furnace does not require an arc, it is easy to regulate the melting heat, making it a suitable option for preserving valuable alloying elements. Moreover, this type of furnace generates a minimal amount of waste and pollutants, contributing to an overall reduction in carbon footprint.
During the operation of an induction furnace, refractory materials provide an essential barrier between molten material and the furnace induction system. The diversified refractory materials supplied by Saint-Gobain Performance Ceramics & Refractories protect the furnace coil from ferrous and non-ferrous molten metals inside the vessel at high temperature. This protected lining is thus fundamental as a protective barrier against the most intense physical, thermal, and chemical stresses occurring during the operation.
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.
