Ladle refining furnace 价格:

SME Group masters mature ladle refining process, and is able to independently provide customers with excellent turnkey ladle refining solutions according to the specifications of finished product.


Ladle refining furnace refers to the equipment that combines the heating and refining function of a steel furnace. It is used to refine the molten steel in the primary steelmaking furnace (electric arc furnace, open hearth furnace, converter), and can adjust the temperature of molten steel, process buffer, and meet the important metallurgical equipment of continuous casting and continuous rolling. Ladle furnace is one of the main equipment for secondary refining.

Main functions of ladle refining furnace:

1, Molten steel heating and heat preservation function. Molten steel obtains new heat energy through arc heating, which can not only make the ladle refining can be supplemented with alloy and adjust the composition, but also can be supplemented with slag, which is convenient for deep desulfurization and deoxidation of molten steel. Moreover, the casting temperature of molten steel required by continuous casting is guaranteed, which is beneficial to improve the quality of dry casting billet.

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

3. Vacuum degassing. After the ladle is lifted into the vacuum tank, the vacuum degassing is carried out by steam jet pump. At the same time, argon gas is blown into the bottom of the ladle to stir the liquid steel. The hydrogen content and nitrogen content in the liquid steel can be removed, and the oxygen content and sulfur content can be further reduced, and the liquid steel with high purity and superior performance can be obtained.

The application of ladle refining furnace for the whole enterprise can at least increase the following benefits: accelerate the production rhythm and improve the entire metallurgical production efficiency.
