The vacuum electroslag remelting (VESR) furnace is a developed special vacuum remelting metallurgical unit for melting high performance alloy based on vacuum arc remelting (VAR) and gas-shielded electroslag remelting (ESR). The steel grades and alloys remelting by VESR are high quality alloy steels
high temperature alloys
precious alloys
anti-corrosion alloys and aluminium
titanium and silver alloys. This article introduces the working principle and metallurgical characteristics of VESR
compares the melting cost
metallurgical quality and properties of steel products melted by VAR
