Изобретение относится к термической обработке двухслойных чугунных прокатных валков и других изделий из углеродистых сплавов на основе железа, в структуре рабочего слоя которых имеется остаточный аустенит. С целью повышения твердости и износостойкости температуру нагрева валков определяют по зависимости: Tн = Ta + Kт HSD/h, oC где Ta - температура превращения остаточного аустенита рабочего слоя, oС; HSD - твердость рабочего слоя валка в литом состоянии, ед. Шора; h - средняя глубина отбела рабочего слоя, мм; Kт - коэффициент, учитывающий интенсивность изменения температуры нагрева в зависимости от соотношения HSD/h, 3 - 10oC•мм/ед. Шора.The invention relates to heat treatment of two-layer cast iron rolling rolls and other products based on iron-based carbon alloys, in the structure of the working layer of which there is residual austenite. In order to increase the hardness and wear resistance of the heating temperature of the rolls is determined depending on: T n = T a + K m HSD / h, o C where T a - residual austenite transformation temperature of the working layer, o C; HSD - hardness of the working layer of the roll in the cast state, units Shora; h is the average depth of the bleached working layer, mm; K t - coefficient taking into account the rate of change of the heating temperature depending on the ratio of HSD / h, 3 - 10 o C • mm / unit. Shora.
