一、简介 电渣重熔技术是近几十年发展起来的一种特种冶炼技术,最早应用该项技术的是苏联、美国。我国在1959年由北京科技大学(当时的北京钢铁学院)将该项技术引入,并取得大量科研成果。目前,国内外电渣熔铸技术应用于生产各种类型的实心体、空心体、包括轧辊、轴、杆、管、环、盘、模块、阀体、轮坯、容器等 I. Introduction Electroslag remelting technology developed in recent decades is a special smelting technology, the earliest application of the technology is the Soviet Union, the United States. China in 1959 by the Beijing University of Science and Technology (then Beijing Iron and Steel Institute) to introduce the technology, and made a lot of scientific research. At present, domestic and international electroslag casting technology used in the production of various types of solid body, hollow body, including rolls, shafts, rods, tubes, rings, plates, modules, valves, wheel blanks, containers, etc.
