PROCESS FOR PRODUCING LOWWCARBON* LOWWNITROGEN HIGH ALLOY STEEL BY USE OF PLASMA ARC FURNACE

摘要

PURPOSE:Molten steel produced by means of a blast furnace or an induction furnace, having carbon not more than 0,3pi, is hot charged to a plasma arc furnace and refined under plasma arc heating at a super high temperature to produce low-C, low-N high alloy steel.
