Abstract: Изобретение относится к металлургии, в частности к способу изготовления легированного материала для комбинированных валков широкополосовых прокатных станов и толстополосовых прокатных станов. В способе получают расплав со следующим химическим составом, мас. %: 2,0-3,5 углерода, 1,0-2,0 кремния, 0,5-2,0 марганца, 1,0-3,0 хрома, 3,5-4,9 никеля, 0,2-2,9 молибдена, остальное железо и примеси. Добавляют более 0,5 мас.% ванадия в количестве до 5,9 мас. %, растворяют в нем и регулируют состав расплава путем легирования за счет установления концентраций углерода и кремния в присутствии никеля, а сумму активностей карбидообразующих элементов регулируют с возможностью образования при его затвердевании микроструктуры, содержащей 1,0-3,0 об.% графита, с условием, чтобы на 1 мм 2  площади наблюдения металлографического шлифа приходилось более 20, однако менее 100 графитовых частиц, а остаток состоял, в основном, из мартенсита, 8-35 об.% эвтектических карбидов и по меньшей мере 1 об. % тонкодисперсных карбидов ванадия. После чего расплав заливают в форму и дают затвердеть. Полученный валок подвергают термообработке. Рабочая часть или рубашка комбинированного валка имеет толщину 10-150 мм. Материал рубашки имеет структуру, состоящую из 1,0-2,5 об.% графита в тонкодисперсном виде с числом частиц более 20 на 1 мм 2  площади металлографического шлифа, 8-35 об.% эвтектических карбидов и 1-20 об.% карбида ванадия в равномерном распределении, остальное мартенсит и обусловленные примесями или технологией изготовления компоненты, и твердость 70-90 единиц по Шору. Изобретение позволяет усовершенствовать способ, посредством которого материал рабочей части комбинированных валков имеет меньшую склонность к прилипанию прокатываемого материала и обладает постоянной высокой стойкостью к истиранию по всей толщине используемой зоны, а литейный материал при этом содержит мелкодисперсные и однородно распределенные выделения графита с малой объемной долей и особые карбиды с малым диаметром зерен, за счет чего рабочая поверхность комбинированного валка имеет неизменные свойства и уменьшается опасность отслаивания и образования трещин на ней. 3 с. и 27 з.п.ф-лы, 1 табл., 4 ил.
