[0002] As a professional technology, argon blowing into the melt has been widely used in the metallurgical casting industry. It has a good effect on removing non-metallic inclusions and harmful gases in the melt, and also has a certain effect on uniforming the chemical composition of the melt and ensuring uniform temperature.

[0003] According to the description of a bottom argon blowing structure of a non-vacuum induction furnace disclosed in the patent website (authorization announcement number: CN216337788U), "The utility model provides a bottom argon blowing structure of a non-vacuum induction furnace, including a non-vacuum induction furnace and a gas diffuser. The non-vacuum induction furnace includes a furnace base, a furnace body and a furnace lining. The gas diffuser is arranged at the bottom of the furnace lining; the gas diffuser includes a plurality of conveying pipes, an outer shell and a breathable block. The conveying pipes are buried in the furnace base, the outer shell is buried in the bottom of the furnace lining, the upper end of the conveying pipe extends into the outer shell and is connected to the inner shell. The vent block is connected. The pre-buried furnace bottom argon blowing structure is used. The vent block is made of refractory material and hydraulically baked at high temperature. When blowing argon, the airflow is optimized and has metal penetration resistance, which can reduce the impact on the furnace lining, prevent melt penetration, and extend the service life of the furnace lining. After the argon passes through the vent block, it produces micron-sized microbubbles with strong adsorption capacity. When blown into the melt, it can effectively absorb non-metallic inclusions and harmful gases, improving the purity of the melt. The gas diffuser is reusable, reducing the frequency of replacement and improving production efficiency.
