| Abstract: | The key technologies on steelmaking based on the slag reserving and duplex slag process in converter in General Steelmaking Plant of Angang Steel Co., Ltd. are introduced, in-cluding slag reserving and slag solidifying technology, slag fluidity controlling and high efficient dephosphorization technology, fast slagging sufficiently and deslagging technology from molten iron, control technology for slag getting dry and content of FeO in final slag and fast operation technolo-gy based on slag reserving and duplex slag process. After these technologies are used the cost is reduced by 12.19 yuan RMB per ton steel. |
