Abstract
Description
technical field
[0001] The invention relates to the technical field of metallurgical smelting, in particular to a method for predicting the solidified microstructure of an electroslag remelted ingot. Background technique
[0002] Electroslag Remelting (ESR) is a special smelting method that combines refining and directional solidification, which can greatly improve the performance of the original remelted electrode material. In the electroslag remelting process, the current flows into the slag through the consumable electrode, then enters the liquid metal molten pool and solidifies the ingot, and finally flows out from the bottom of the ingot. Since the conductivity of the slag in the entire power supply circuit is much greater than that of the consumable electrode, ingot and external short network, the slag pool will occupy most of the voltage drop of the secondary voltage of the transformer, thereby generating a large amount of Joule heat in the slag pool, which is Electr...
