SR Smelting Furnace

Coreless induction furnace is a special induction furnaces. There is no metal core passing through the inductor in the induction furnace. The alternating magnetic field is mainly generated by the induction coil surrounding the crucible. Classification of Induction Furnaces: According to the different power supply frequencies, coreless induction furnaces can be divided into:  Industrial frequency induction furnaces Triple frequency induction furnaces Generator set medium frequency induction furnaces Thyristor medium frequency induction furnaces High frequency induction furnaces Coreless Induction Furnace Working Principle The coreless induction furnaces working principle is to heat the metal by the alternating magnetic field generated by the heating current in the furnace. The details are as follows: The metal charge in the IF is placed in a crucible without a ferromagnetic core. When the induction coil is energized, high-frequency alternating current is generated to form a mag...

  Ladle refining furnaces is an electric furnace that has the heating and refining functions of steelmaking furnace.  It is mainly used to further refine the molten steel melted by the primary refining furnace (such as electric arc furnace, open hearth furnace, converter), and can adjust the temperature of the molten steel, playing the role of process buffer to meet the needs of subsequent processes such as continuous casting and continuous rolling. The LF refining furnace plays the role of a "buffer" in the steelmaking process, balancing the production rhythm between the steelmaking furnace and the continuous casting machine. The Role of Ladle Refining Furnaces LRF plays several important roles in the steelmaking process, such as 1. Desulfurization & dephosphorization: The refining furnace produced by Sanrui, a ladle refining furnace manufacturer, reduces the sulfur and phosphorus content in the molten steel by adding flux and adjusting the temperature, thereby improving...

  An electric arc furnace is an electric furnaces that uses an electric arc to generate high temperatures to melt ores, metals, and other materials. Its working principle is to use electric current to pass through electrodes to form an arc. The high temperature generated by the arc can reach thousands of degrees Celsius, which is enough to melt metals. The EAF used in industry is mainly divided into direct heating type. In this type of electric arc furnace, the arc occurs between a special electrode rod and the smelted charge. The temperature of the electric furnace can reach 1,800 °C (3,272 °F), while the temperature of the EAF melting furnace used in the laboratory can rise to as high as 3,000 °C (5,432 °F). How Does an Electric Arc Furnace Work? The electric arc furnace has greater process flexibility than other steelmaking furnaces. It can effectively remove impurities such as sulfur and phosphorus. The furnace temperature is easy to control and the equipment occupies a small ...
