VD / VOD Function
As a vacuum refining equipment widely used in high-end steel manufacturing, it has excellent degassing and deoxidizing effects. It achieves efficient removal of hydrogen and nitrogen from the steel by creating a highly vacuumed environment, which greatly reduces the amount of harmful gases in the finished steel, which is essential for improving the toughness and ductility of the steel. This process not only significantly improves the intrinsic quality of the steel, but also extends its service life, which is especially critical in the manufacture of specialty steel products that require extreme purity and high performance.
The VD furnace effectively reduces the hydrogen and nitrogen content of the steel, removes oxygen from the steel through carbon and oxygen reactions, and desulfurizes the steel through the full reaction of the alkaline top slag with the molten steel, in addition to homogenizing the composition and temperature. With its excellent performance in degassing, deoxygenation, desulfurization, composition and temperature homogenization, the VD furnace has become an indispensable core technological equipment in the modern steel industry to improve product quality, optimize the production process, and meet the demand of the high-end material market.
