摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to technology of heat treatment of steel and can be used u0434u043bu00a0 thermal machining machines responsible u043du0430u0437u043du0430u0447u0435u043du0438u00a0. the purpose of u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0 increased operational stability. u043fu043eu043au043eu0432u043au0443 steel 15 u0445u0441u043du0434 diameter of 300 mm and a length of 1500 mm to ride on the bars. the temperature of deformation 920u0441, cooling in water.then the forgings are u0442u0435u0440u043cu043eu0446u0438u043au043bu0438u0447u0435u0441u043au043eu0439 processing near the point u0430u04411. u0432u0435u0434u0435u0442u0441u00a0 processing in such a manner that the heat on the point u0430u04411 u043eu0441u0443u0449u0435u0441u0442u0432u043bu00a0u0435u0442u0441u00a0 5 - 20u0441 and cooling to temperatures above the u043cu0430u0440u0442u0435u043du0441u0438u0442u043du043eu0433u043e u043fu0440u0435u0432u0440u0430u0449u0435u043du0438u00a0. the number of cycles must provide initial temperature u0430u04411. 2, table 2).
