“ZF”法是鞍钢和鞍山钢铁学院共同研制的浇铸沸腾钢新工艺,本文通过实验室模拟实验研究和现场测温、倾倒钢锭等方法全面研究了ZF6.67t沸腾钢锭的液芯轧制变形特点,可轧液芯率,以及钢锭的凝固率曲线。根据该锭型特点,制订了新的工艺制度,使ZF6.67t沸腾钢锭的平均装炉温度达到了1006.2℃,液芯加热率达到82.58％,从而提高均热炉生产能力1/3,减少烧损0.7％,节约煤气46.5％,经济效益显著。目前该工艺已正式投入生产2年半,证明“ZF”法是保证液芯加热、液芯轧制的有效措施之一。
The “ZF” method is a new technology of casting and boiling steel jointly developed by Anshan Iron and Steel Institute of Anshan Iron and Steel Institute. In this paper, through the laboratory simulation research and on-site temperature measurement, pouring steel ingot and other methods comprehensively studied the deformation characteristics of liquid core rolling ZF6.67t ingot ingot , Can roll hydraulic core rate, as well as the solidification rate of steel ingot curve. According to the characteristics of the ingot, a new process system has been formulated so that the average loading temperature of the ZF6.67t ingot reaches 1006.2 ° C and the heating rate of the liquid core reaches 82.58%, thereby increasing the production capacity of the soaking furnace by 1/3 and reducing the burn rate Loss of 0.7%, 46.5% gas savings, significant economic benefits. Currently the process has been officially put into production for two and a half years, proving “ZF” law is one of the effective measures to ensure liquid core heating, liquid core rolling.
