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.

HN73MBTYU耐热合金径向位移轧制能力过程评价

摘要——本文对小直径棒材径向位移轧制工艺能力进行了实验研究。这些由耐热合金 HN73MBTYU 制成，在 MISIS 中试轧机上指定了直径为 60 毫米的铸锭轧制计划，用于直径为 22 毫米的棒材。进行了以下操作：对获得的杆进行质量评估，以及是否符合当前规范和技术文件的要求。已经证明了使用符合技术文件要求的 60 毫米直径钢锭生产小直径 HN73MBTYU 合金棒材的可能性，并使用技术和径向位移轧机。经过测试的技术解决方案非常适合在微型和微型冶金工厂环境中进行工业引入。
