Investigation of recycling technology for long mandrel bars of a continuous mill

Abstract

We discuss the possibility of pressure treatment of workpieces with the help of screw rolling aimed at subsequent production of the working parts of continuous mandrels of the mill. We performed the experimental rolling of ingots obtained by the method of electroslag remelting. In the present work, we also propose qualitative assessments of the micro- and macrostructures, which confirm the possibility of application of the procedure of rolling of workpieces in the course of subsequent production of the working parts of mandrels of continuous mills.
