摘要：
An improved oxidative production technology for 110Г13Л manganese steel in a 25-t arc furnace is considered. The basic periods of the process are described. The slag conditions in steel production are discussed. The activity of oxygen in the metal is assessed on the basis of practical data regarding the slag composition in the oxidative and reductive periods. The oxygen activity in the metal is plotted as a function of the total content of manganese and iron oxides in the slag. In addition, a method is proposed for determining the required aluminum content for reduction of the metal, so as to obtain the required quantity in the final melt. The influence of the steel’s aluminum content on its impact strength is investigated. © 2015, Allerton Press, Inc.
