MECHANICAL CHARACTERISTICS OF INDUSTRIAL TYPES OF STEEL AT HARDENING OF INGOTS AND SLUGS

Abstract

The analysis of possibility of the fire cracks arising is carried out on the basis of existing data on changing of mechanical characteristics of industrial steel grades at high temperatures (in the processes of hardening and cooling in ingots and slugs). It is determined that at casting of slugs at MNLZ the failure of uniformity of hard skin in the initial period of its formation is possible.
