你愿要哪一种连铸板坯?从照片1(略)即可看出,左边铸坯的内部组织结构要比右边的好得多。它们是取自同一炉次同一板坯铸机的同一流铸坯的宏观浸蚀照片。左边照片柱状晶区减小和中心疏松极少,这一板坯无疑是较好的产品。为什么会有此差异呢?答案就是电磁搅拌。为边的铸坯在凝固期间受到丁安装在冷却段上的感应线圈的磁力搅拌。电磁搅拌是改变铸坯组织结构的一条途径。近来,钢铁生产者对此已加深了认识。由于应用上的需要,钢铁生产者提议考虑安装搅拌器以提供优质铸坯。用电磁
Which kind of continuous casting slab you want? From the photo 1 (omitted), we can see that the internal structure of the left slab is much better than the right one. They are macroscopically etched pictures of the same cast strand taken from the same slab caster. The left photo columnar grain area decreases and the center is very loose, this slab is undoubtedly a better product. Why is there such a difference? The answer is electromagnetic stirring. The side slab is subjected to magnetic stirring during the solidification of the induction coil mounted on the cooling section. Electromagnetic stirring is to change the structure of the slab a way. Recently, steel producers have deepened their understanding. Due to the needs of the application, the steel producer proposes to consider installing a mixer to provide a good strand. Electromagnetic
