Abstract

To add alloying elements into a pure copper melt, the wire-feeding efficiency of cored (alloy containing) wire was evaluated using a commercial, computational fluid-dynamics program. The model design was based on an industrial-scale production line. The variables calculated included wire feed rate, melt temperature, wire diameter, melt flow rate and wire temperature. Efficiency was evaluated after a series of calculations based on the penetration depth of the alloy-wire into the molten copper bath. Of the five variables investigated, the wire feed rate and wire diameter were the most influential factors affecting the feeding efficiency of the cored-wire.
在铜熔体中添加合金元素的补丝效率评价
为了在纯铜熔体中添加合金元素,使用商业计算流体动力学程序评估了包芯(含合金)线材的送丝效率。模型的设计是基于工业规模的生产线。计算的变量包括送丝速度、熔体温度、线材直径、熔体流量和线材温度。根据合金丝在熔铜槽中的渗透深度进行了一系列计算,评估了效率。在5个变量中,送丝速度和丝径是影响包芯丝送丝效率的主要因素。
