What are the key functions of ladle refining furnace?


Ladle refining furnace refers to the machinery and equipment that takes into account the heating and refining function of converter. It is used to refine the molten steel in the primary smelting furnace (medium frequency furnace, blast furnace and steelmaking furnace), and can adjust the molten steel temperature and cache the processing technology, so as to achieve the key metallurgical machinery of steel rolling and rolling mill. Ladle furnace is one of the key machines and equipment for out of furnace refining.


Key functions of ladle refining furnace:


1. Make the liquid steel warm and have the function of heat insulation. According to the electric arc heating, the molten steel obtains a new thermal engineering, which can not only add aluminum alloy and adjust the composition during ladle refining, but also add slag material, which is conducive to deep flue gas desulfurization and ammonia removal of molten steel. Moreover, the specified pouring temperature of liquid steel can be ensured, which is beneficial to the improvement of dry billet quality.


2. Argon bottle mixing function. The argon cylinder blows the atmosphere into the molten steel according to the permeable brick installed at the bottom of the ladle, and the molten steel gets a certain mixing function.


3. Vacuum pump vacuum distillation function. After the ladle is hoisted into a similar vacuum tank, the steam jet pump is selected to carry out vacuum pump decompression distillation. At the same time, the argon cylinder is blown into the ladle bottom to stir the liquid steel, which can remove the hydrogen content and nitrogen content in the liquid steel, further reduce the oxygen content and sulfur content, and obtain high purity liquid steel and materials with service performance.


For all companies, the application of ladle refining furnace can at least improve the following benefits: accelerate the sense of manufacturing rhythm and improve the productivity of the whole metallurgical industry. Main uses: ladle refining furnace is widely used in industrial production, steel, metallurgical industry and other fields.
