NAK55 is pre-hardened steel which can be used without any heat treatment. To maintain and utilize the efficient properties of NAK55, we use VAR process. However since NAK55 contains much vaporic elements of manganese and copper, cost of VAR operation increases because we need higher contents of these elements in electrode and we need turning of ingot surface in which manganese and copper are segregated. To solve these problems we have developed VAR pressure control system with the control valve in the vacuum duct to restrain the vaporization of manganese and copper. Subsequently we have established New VAR Process under the best pressure for stable operation.In addition, using the pressure control system, we have also developed New Hot Top Process.This paper describes the New VAR Process and the New Hot Top Process.
