Main Functions Of Ladle Refining Furnace
1. Heating & heat preservation of molten steel.
Molten steel obtains new heat energy through arc heating, which not only allows alloys to be added and composition to be adjusted during ladle refining, but also allows slag to be added, which is convenient for deep desulfurization and deoxidation of molten steel.
Moreover, the molten steel pouring temperature required by continuous casting is guaranteed, which is beneficial to the improvement of dry casting billet quality.
2. Argon stirring function.
Argon is blown into the molten steel through the air-permeable bricks installed at the bottom of the ladle, and the molten steel obtains a certain stirring function.
3. Vacuum degassing function.
After the ladle is hoisted into the vacuum tank, a steam jet pump is used for vacuum degassing. At the same time, argon is blown into the bottom of the ladle to stir the molten steel, which can remove the hydrogen and nitrogen content in the molten steel, and further reduce the oxygen and sulfur content, and finally obtain a higher purity molten steel and a material with superior performance.
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 overall metallurgical production efficiency.
