Functions of Ladle Refining Furnace

Ladle refining furnace (Ladle furnace) refers to equipment that has both the heating and refining functions of a steelmaking furnace.

It is an important metallurgical equipment used for refining molten steel melted in primary furnaces (electric arc furnace, open hearth, converter), and can adjust the temperature of molten steel, process buffering, and meet continuous casting and continuous rolling requirements.

Ladle furnace is one of the main equipment for refining outside the furnace.

Main Functions of Ladle Refining Furnace:

1. The function of heating the molten steel and keeping it warm.

The molten steel obtains new thermal energy through arc heating, which can not only add alloys and adjust components during ladle refining, but also add slag, which is convenient for deep desulfurization and deoxidation of molten steel.

Moreover, the molten steel opening temperature required by continuous casting is guaranteed, which is beneficial to the improvement of the quality of the dry casting billet.

2. Argon stirring function.

Argon gas is blown into the molten steel through the breathable brick installed at the bottom of the ladle, and the molten steel obtains a certain stirring function.

3. Vacuum degassing function.

After the ladle is lifted into the vacuum tank, the steam jet pump is used for vacuum degassing, and the molten steel is stirred by blowing argon at the bottom of the ladle, which can remove the hydrogen content and nitrogen content in the molten steel, and further reduce the oxygen content and sulfur content. Finally, a higher purity molten steel and a material with superior performance are obtained.

The application of ladle refining furnace can at least increase the following benefits for the entire enterprise.

Speed ​​up the production rhythm and improve the entire metallurgical production efficiency.

Application Areas: 

Ladle refining furnaces are widely used in industry, steel, metallurgy and other industries
