Effect of electromagnetic stirring on metallurgical quality of GCr15 electroslag ingot

Abstract

As a special metallurgical method, electroslag remelting (ESR) technology has been widely used. The most remarkable advantage for ESR is that it can improve the purity and solidification quality of metal. In the traditional metallurgical process, molten steel is treated in lined vessels from smelting to casting. The molten steel will inevitably be polluted by the lining, such as the spalling of refractory, and the involvement of mold flux [1] . These accidental and irregular large inclusions have a very adverse effect on the properties of metals. In the ESR process, the contact area between slag and molten

“…Several articles, e.g. [11][12][13][14][15][16][17][18][19] deal with the relationship between chemical composition, structure, mechanical properties, heat or corrosion resistance of austenitic nodular cast irons, but just a few of them deal with the fatigue properties. For this reason, the paper deals with the fatigue resistance of austenitic nodular cast iron.…”
