1, Make steel heating and insulation function. Steel through the electric arc heating to obtain new thermal energy, which not only can make ladle refining can make up the alloy and adjust the composition, but also can make up the slag material, to facilitate deep desulfurization and deoxidation of the steel. And continuous casting requirements of the molten steel open pouring temperature is guaranteed, favorable dry cast billet quality improvement.
2, Argon gas stirring function. Argon gas through the breathable brick installed in the bottom of the ladle to blow atmosphere into the molten steel, the molten steel to obtain a certain stirring function.
3, Vacuum degassing function. Through the ladle lifting into the vacuum tank, the steam jet pump is used for vacuum degassing, while blowing argon into the steel through the bottom of the ladle to stir the steel, which can remove the hydrogen content and nitrogen content of the steel, and further reduce the oxygen content and sulfur content, and finally obtain a higher purity of the steel and superior performance of the material.
The application of ladle refining furnace for the whole enterprise, at least the following benefits can be added: speed up the production pace and improve the overall metallurgical production efficiency.
