用热扭转试验机，实现了热变形模拟轴承钢控制轧制工艺。研究了形变过程中所发生的静态和动态软化过程，观察了形变后的组织，证实在生产过程中实现的可能性，为在生产中推广使用提供了科学依据。 Hot Torsion testing machine, to achieve the thermal deformation of the bearing steel controlled rolling process. The static and dynamic softening process occurred in the deformation process was studied. The deformed structure was observed to confirm the possibility of its realization in the production process, which provided a scientific basis for the promotion of its use in production.
