连铸工艺产生的氟主要来源于连铸保护渣。氟的存在除涉及地球环境问题以外还对连铸本身和连铸机设备也有不良的影响 ,因此连铸工艺采用无氟技术是必要的。但是由于结晶器对凝固壳的吸热控制时不可避免地需要使用枪晶石 ,因此无氟问题一直没有得到解决。此番连铸无氟技术的确立 Fluoride produced by the continuous casting process mainly comes from continuous casting mold flux. In addition to the problems of the Earth’s environment, the presence of fluorine also has an adverse effect on the continuous casting itself and in the caster equipment. Therefore, it is necessary to use fluorine-free technology in the continuous casting process. However, the problem of fluorine-free has not been solved due to the inevitable need of using gunite for the endothermic control of the solidified shell by the mold. This time continuous casting fluorine-free technology established
