Optimization of Electromagnetic Horizontal Continuous Casting Technology of Phosphor Bronze Slab

In order to improve the edge quality of horizontal continuous casting phosphor bronze slab, three methods including applying silicon steel at ends of the traveling magnetic field stirrer, changing the length of traveling magnetic field stirrer, and reducing the ends current intensity of traveling magnetic field stirrer were proposed, and a numerical simulation method was used to study the flow and solidification process of continuous casting phosphor bronze slab. The results show that compared to the other two methods, the method of placing the silicon steel sheet on the edge of the traveling electromagnet stirrer is more beneficial to improve the melt flow. When the length of the silicon steel sheet is 150 mm, the strong flow at the melt ends disappears and the ends melt solidification process is more uniform, which is helpful to prevent the crack and segregation defect and improve the edge quality of continuous casting phosphor bronze slab.
