Effect of hot-top on the molten pool of Electro-Slag Remelting

摘要：

　　Electro-Slag Remelting(ESR) technology often used in the preparation of aerospace materials such as high temperature alloys,the shape of the molten pool is a key factor to get the high quality ESR ingot.In this paper,the hot-top is applied in the ESR system to improve the shape of the molten pool,and the numerical simulation method is used to decide the hot-top position,the results show that:during the ESR process,when the hot-top is imposed at the junction of slag and ingot,the molten pool is shallow,however,when the hot-top is all located at slag part or all at ingot part,it will deepen the pool depth which is harmful to acquire the high quality ESR ingots.
