Studying of Influence of Rotation of the Spent Electrode on the Microfirmness of the Received Preparation of Steel AISI 420 at Electroslag Remelting

摘要

Data of skilled electroslag remelting of the spent brand AISI 420 steel electrodes on various technologies are provided (with rotation and without rotation of the spent electrode). Are noted, features of influence of rotation of the spent electrode on conditions of the course of process of remelting and crystallization of an ingot. Influence of a way of remelting on a complex of properties of the received ingot is analysed. The analysis of results of researches showed increase in uniformity of the studied properties at realization of technology of electroslag remelting with rotation of the spent electrode on the melting course.
