As a key equipment for secondary refining in the metallurgical industry, the refining furnace is a critical link to improve the quality of metal materials and achieve refined production. Widely adapted to smelting scenarios such as iron and steel, and special alloys, it lays a solid foundation for the production of high-quality metal products.
Mainstream models including LF ladle refining furnace and VOD vacuum refining furnace each have technical advantages and applicable scenarios. The LF furnace, with electric arc heating and argon stirring as the core, can realize molten steel temperature rise and adjustment, precise fine-tuning of components, and achieve remarkable desulfurization effect—reducing the sulfur content of molten steel to below 0.005%. It also improves the purity of molten steel and reduces the content of inclusions and gases. The VOD furnace relies on vacuum technology to deeply remove harmful gases such as hydrogen and nitrogen from molten steel, realize ultra-low carbon smelting, and meet the production requirements of high-end materials such as stainless steel and superalloy.
Adopting closed operation and reductive refining process, the refining furnace features high heating efficiency and better energy utilization than traditional smelting equipment. Some models can also reduce metal volatilization loss and lower unit production energy consumption. Meanwhile, the equipment is flexible in operation, with adjustable parameters according to different steel grades and process requirements, and the component control accuracy can reach ±0.01%. It can not only match the primary smelting process of electric furnaces and converters, but also provide molten steel with stable temperature and components for continuous casting production, adapting to the production needs of various categories such as ordinary steel and special steel.
Under the trend of green production and resource recycling, the refining furnace can conduct refined processing of recycled metal raw materials such as steel scrap, effectively removing impurities and optimizing components to make recycled metals meet high-quality application standards. It helps the metallurgical industry reduce costs, increase efficiency and realize resource recycling, becoming an important production support for iron and steel, high-end equipment manufacturing and other fields.
