As a professional ladle furnace manufacturer, Xi’an Hani has more than 20-year experience in manufacturing the research and development, design, production, installation and construction services of ladle refining furnace complete equipment and auxiliary accessories. Its business covers the whole country and is exported to the world.
A Ladle refining furnace refers to the equipment with the function of heating and refining of steel-making furnace. It is important metallurgical equipment used to refine molten steel from primary smelting furnaces (electric arc furnaces, open hearth furnaces and converters), adjust the temperature of molten steel, buffer the process, and meet the requirements of continuous casting and continuous rolling. A ladle furnace is one of the main pieces of equipment for refining outside the furnace.
1. Main Functions of Ladle Furnace Manufacturer:
Make the molten steel temperature rise and keep it warm. The molten steel is heated by an electric arc to obtain new heat energy, which can not only add alloy and adjust composition during ladle refining, but also add slag to facilitate deep desulfurization and deoxidation of molten steel. Moreover, the opening temperature of molten steel required by continuous casting can be guaranteed, which is beneficial to the improvement of the quality of the dry-cast slab.
Argon stirring function. Argon is blown into the molten steel through the permeable brick installed at the bottom of the ladle, and the molten steel has a certain stirring function.
Vacuum degassing function. After the ladle is hoisted into the vacuum tank, the steam jet pump is used for vacuum degassing, and argon is blown into the bottom of the ladle to stir the molten steel. The hydrogen content and nitrogen content in the molten steel can be removed, and the oxygen content and sulfur content can be further reduced. Finally, molten steel with high purity and excellent performance can be obtained.
For the whole enterprise, the application of a ladle refining furnace can at least increase the following benefits: speed up the production rhythm and improve the overall metallurgical production efficiency. Application: ladle refining furnace is widely used in industry, steel, metallurgy and other industries.
