4, high quality special steel high efficiency, low cost special metallurgy new process
1) Tertiary refining technology
Following a conventional EAF or converter process with three additional refinings, such as a vacuum consumable furnace or electroslag remelting, high purity specialty steels can be obtained for efficient and low-cost preparation of specialty steels and other high-performance metal materials for aerospace and other applications.
2) The new generation of special steel purification, homogenization refining technology research and development of a new generation of special steel ladle clean refining technology that is non-polluting to molten steel, characterized by heating and deoxidation, new technology of pressurized nitrogen enhancement metallurgy of high-end stainless steel, electroslag remelting technology based on conductive crystallizer, etc., for the production of high-end alloy steel.
