Abstract

The paper presents an experimental study on the technological capabilities of radial-displacement rolling of small diameter rods. These are made of heat-resistant alloy HN73MBTYU on pilot mills MISIS specifying the ingot rolling schedule with a diameter of 60 mm for a 22-mm-diameter rod. The following was conducted: a quality assessment of the rod obtained, as well as a compliance with the requirements of the current normative and technical documentation. The production possibility of small diameter rods of HN73MBTYU alloy from ingots with a 60-mm diameter that meets the technical documentation requirements, with the use of technology and radial displacement rolling mills, has been proved. The tested technological solutions have a high degree of readiness for industrial introduction in mini- and micro-metallurgical plant environment.
