据日本“《铁钢》”1986年第4期报道:新日铁公司开发了一种在连铸包内安装陶瓷过滤器清除非金属夹杂物的技术,已经开始应用于实际生产操作。开发前期,首先进行了基础试验,弄清了钢水落差、钢水温度,过滤器的孔径对钢水流速的影响以及去除夹杂物的效果。在此基础上,进行了实际应用试验和研究,曾在中间包内砌筑了水平大断面过滤器隔墙,从而保证了有一定的钢水落差和钢水通过过滤器时必
According to Japan “” Iron and Steel “” 1986 the fourth period reported: Nippon Steel Corporation has developed a continuous casting package ceramic filter installed to remove non-metallic inclusions in technology has already begun to be used in actual production operations. Early development, the first basic test to clarify the molten steel drop, the temperature of the molten steel, the filter pore size of the molten steel flow rate and the effect of removing inclusions. On this basis, the actual application of the test and study, had built in the tundish horizontal section filter partition wall, thus ensuring a certain drop of molten steel and molten steel must pass through the filter
