Abstract
It is shown that the problem of improvement of the quality of solid rolled wheels was comprehensively solved by upgrading the currently available steel melting and pouring technologies and scientific search for more suitable modes of press rolling of the billets, antiflocking treatment and optimization of heat treatment parameters (heating for quenching, accelerated cooling and low-temperature tempering). It is quite obvious, however, that the quality of end products in this complex technological scheme of wheel production is largely initially determined by the steel properties, the influence of a range of metallurgical factors at the stage of metal melting in the furnace, out-of-furnace processing and pouring. 16 Ref., 2 Tabl., 2 Fig.
