Способ изготовления полых тел вращения, имеющих фасонную боковую поверхность, включающий поверхностный нагрев заготовки катка в индукторе Т.В.Ч, отличающийся тем, что поверхностный нагрев заготовки катка в индукторе Т.В.Ч. производится на пустотелой оправке с охлаждаемым сердечником, предотвращающей сквозной прогрев заготовки катка, и последующей прокаткой этой заготовки в центрах, между двумя сближающимися и вращающимися профильными валками, увеличивает производительность труда, улучшает качество прокатываемого профиля боковых поверхностей катка и снижает процент брака.A method of manufacturing hollow bodies of revolution having a shaped lateral surface, including surface heating of the roller blank in the inductor T.V.CH, characterized in that the surface heating of the blank of the roller in the inductor T.V. It is made on a hollow mandrel with a cooled core, which prevents through heating of the roller billet, and subsequent rolling of this billet in the centers between two converging and rotating profile rolls, increases labor productivity, improves the quality of the rolled profile of the side surfaces of the roller and reduces the percentage of rejects.
