Automatic Bottom Gas Diffuser System for In Foundry Refining

Refining and purification system for induction furnace:

The biggest advantage of this system is that after low-cost transformation of ordinary induction furnace, it can completely replace the function of ladle refining furnace (LF). The same metal liquid refining and purification effect can be achieved while reducing one production process.

This system adds furnace top gas protection, furnace bottom argon blowing stirring and refining purification functions to ordinary furnaces. During the heating and smelting process of the furnace, countless tiny argon bubbles are blown into the furnace bottom. During the floating process of argon bubbles, the surface tension and volume expansion are used to maintain a negative pressure "vacuum chamber", adsorbing harmful gases and impurities dispersed in the molten metal to the surface of the molten metal. The high-efficiency refining and quality-improving agent covered on the surface reacts and adsorbs physically and chemically, so that the molten metal can quickly achieve the refining purposes such as degassing, sulfur and phosphorus reduction, and inclusion removal, which significantly improves the cleanliness of the metal. In addition, with the top argon blowing during the heating and smelting process of the furnace, an argon curtain protection layer is provided for the surface of the molten metal to isolate the air and form an "argon vacuum" atmosphere, further improving the refining and purification effect.

Advantages of this system:

1) The intelligent control system program can realize functions such as gas source purification, gas source monitoring and blockage alarm, intelligent unblocking of bottom blowing blockage, etc. The effective safety protection mechanism ensures stable and efficient production operation;

2) Simple and fast: It can be installed and upgraded on the existing induction furnace for heating and smelting without repeated investment. The operation is simple and convenient, and it can be put into production immediately after installation;

3) Low operating cost: The cost of production according to this method is tens of USD/ton of steel, while the traditional ladle refining (LF) furnace is hundreds of USD/ton of steel.
