| 摘 要： | 分析了邯钢二炼钢厂板坯中心偏析的成因。阐述了如何解决由其引起的铸坯质量问题,采取了如下措施:要求中间包钢水S]<0.015％,P]<0.015％;应用PHOENICS软件,优化了浸入式水口参数,在不增加专门的压下设备条件下,通过逐渐缩小二冷夹辊开口度,在铸坯凝固70％部位,加大夹辊加下量,实现了铸坯总压下4.5 mm的轻压下。

| Abstract: | The causes of central segregation of slabs in No. 2 Steel making plant of Handan I-ron and Steel Corporation are analyzed. How to solve the slabs quality problem is discussed. In order to solve the problem caused by central segregation, some measures are taken as follow: the percent of S] and P]in tundish should be below 0. 015% ;PHIRNICS software is set to optimize parameters for submerged nozzle; In case, specialized compressing equipment is not increased , and the open degree of roller in the second cooling becomes smaller and smaller, the compressing content will increase and the total slight compressing of 4. 5mm is realized. The production practice shows that the quality of slabs is increased greatly and the results are good. |
