众所周知,高碳含量易于使连铸钢产生中心疏松和偏析缺陷。这些缺陷一旦形成将会影响最终产品的力学及疲劳性能。在减少这些中心缺陷方面,有关人员做了许多尝试,包括电磁搅拌、轻压下、低温浇注和在最终凝固区域的充分冷却。这些方法中,电磁搅拌法因能有效地减少中心缺陷而被广泛采用。通常根据搅拌位置的不同将电 As we all know, high carbon content tends to make the center of the continuous casting steel loose and segregation defects. Once formed, these imperfections will affect the mechanical and fatigue properties of the final product. Many attempts have been made to reduce these center defects, including electromagnetic stirring, soft reduction, low temperature casting, and adequate cooling in the final solidified area. Among these methods, the electromagnetic stirring method is widely used because it can effectively reduce the center defect. Usually according to the mixing position will be different
