Abstract

1. Способ изготовления оправки для использования в прошивном трубопрокатном стане для изготовления бесшовной стальной трубы, отличающийся тем, что способ изготовления оправки для прошивки-прокатки включает: этап дугового напыления расплавленной железной проволоки и напыление ее расплавленного материала на поверхность основного металла оправки с использованием дугового распылителя с образованием пленки, содержащей оксид и железо на поверхности основного металла оправки, при этом на этапе дугового напыления поверхность основного металла оправки разделяют на множество секций в осевом направлении оправки и, в свою очередь, дуговое напыление осуществляют отдельно в каждой из множества секций, при этом угол пересечения между осевой линией распыляемого потока из дугового распылителя и поверхностью основного металла оправки поддерживают в диапазоне от 35˚ до 90˚.2. Способ изготовления оправки для прошивки-прокатки по п. 1, отличающийся тем, что оправка имеет форму пули и включает в себя корпусную часть и концевую часть, амножество секций содержат область корпусной части и область концевой части.1. A method of manufacturing a mandrel for use in a piercing tube mill for manufacturing a seamless steel pipe, characterized in that the method of manufacturing a mandrel for piercing-rolling includes: the step of arc spraying molten iron wire and spraying its molten material onto the surface of the base metal of the mandrel using an arc sprayer with the formation of a film containing oxide and iron on the surface of the base metal of the mandrel, while at the stage of arc spraying the surface of the main metal alla mandrels are divided into many sections in the axial direction of the mandrel and, in turn, arc spraying is carried out separately in each of the many sections, while the angle of intersection between the axial line of the sprayed stream from the arc sprayer and the surface of the base metal of the mandrel is maintained in the range from 35˚ to 90˚.2. A method of manufacturing a mandrel for firmware-rolling according to claim 1, characterized in that the mandrel is in the form of a bullet and includes a body part and an end part, a plurality of sections comprise an area of the body part and an area of the end part.
