A new low magnetic shielding (LMS) copper alloy (Cu–40Mn–2Al) connected with copper through tungsten inert gas (TIG) welding to form a new two-stage mold for soft-contact electromagnetic continuous casting is described. Experimental and numerical simulation methods are used to study the LMS effect, the cooling performance, and the strength of the two-stage mold. With the solid solution of a large proportion of the Mn and a little of Al elements in the copper, the electrical resistivity of the copper alloy increases significantly. Furthermore, the thickness of the skin layer is about 1.5 times larger than that of the base alloy (Cu–10Mn–5Si–3Al–1.2P–1Ti), which greatly reduces the LMS effect. Numerical simulation results agree well with the experimental results on the LMS effect of the copper alloy. The electromagnetic force reaches the maximum value at the meniscus and gradually attenuates from the surface to the center of the billet. Critically, the electromagnetic force exceeds the critical value required for pushing the molten steel away the wall of the mold. Thus, the developed copper alloy achieves the requirements for two-stage mold with the properties of the LMS effect, the well cooling effect, the high strength.

低磁屏蔽软接触电磁连铸两段式结晶器的制作与仿真
描述了一种新的低磁屏蔽 (LMS) 铜合金 (Cu–40Mn–2Al) 通过钨极惰性气体保护 (TIG) 焊接与铜连接以形成用于软接触电磁连铸的新型两级结晶器。采用实验和数值模拟方法研究了LMS效应、冷却性能和两级模具的强度。大量的Mn和少量的Al元素固溶于铜中，使铜合金的电阻率显着增加。此外，表层的厚度大约是基体合金（Cu-10Mn-5Si-3Al-1.2P-1Ti）的 1.5 倍，这大大降低了 LMS 效应。数值模拟结果与铜合金LMS效应的实验结果吻合良好。电磁力在弯液面处达到最大值，并从坯料表面到中心逐渐衰减。至关重要的是，电磁力超过了将钢水推离模具壁所需的临界值。因此，所开发的铜合金达到了二级模具的要求，具有LMS效应、冷却效果好、强度高等特点。
