Arc slag remelting for high strength steel & various alloys

Arc Slag Remelting (ASR) is a variant of standard ESR that accumulated advantages of ESR and VAR. Principles of ASR and it comparison with the standard ESR are given. Also discussed possibilities and limitation to replace ESR by ASR to reduce specific electric power consumption to the level of 800 kWt* hour per ton. Data full scale rectangular ASR ingot of HSLA and medium alloed steel melting are presented along with the metal quality examination. Requirements to the equipment for ASR commercialization are summarized. Also discussed area of ASR application for high alloyed steel and alloys as well as for titanium.
