Description

Technical Field

[0001] The present application relates to the technical field of stainless steel smelting, and more specifically, to an induction furnace for stainless steel smelting. Background Art

[0002] Stainless steel induction furnace is an induction heating furnace designed and manufactured for stainless steel forging heating, stamping heating or tempering heating. Since stainless steel does not have magnetism, the heating process is different from that of ordinary carbon alloy steel. Stainless steel induction furnace requires a special design. It uses the induction heating effect to heat and melt the metal in a steelmaking method. It is particularly suitable for smelting a small amount of high-quality steel and alloys with high-quality raw materials (high-quality scrap steel, ferroalloys, etc.). The vacuum induction furnace equipped with a vacuum system is an important equipment for smelting high-quality alloys.

[0003] When the induction heating furnace is in use, after the stainless steel smelting is completed, the operator needs to control the rotation of the furnace body from the side to pour the molten steel into the required mold. However, when the molten steel is pouring, it may leak. Since the operator is located on one side of the induction heating furnace and there is no protection in the middle, when the steel leaks, the molten steel may splash on the operator, causing a safety accident. At the same time, when the steel leaks, emergency measures can only be taken by nearby operators, but this method has a certain delay and cannot handle the molten steel in a timely and rapid manner.
