Steel ingot pulling out die erect loss lag solution method

摘要

PURPOSE: To provide a steel ingot pull-down type electro-slag remelting method in which the steel ingot having good surface can be obtd. ;CONSTITUTION: At the time of ingot-making by the steel ingot pull-down type electro-slag remelting method, the steel ingot and the slag constituting a consumable electrode are selected so as to satisfy two conditions of (a) the m.p. of the steel ingot is higher than the solidified point of the slag and (b) the solidified point of the ingot is higher than the solidified point of the slag by within 65°C to execute the ingot-making.;COPYRIGHT: (C)1993,JPO&Japio
