本文扼要地阐述了旧轧机存在的主要问题,并按照短应力线与预应力相结合的原则,设计成功了一种小型高刚度轧机。介绍了该轧机的结构及其主要特点,该机投产以来的经济效益。本文除了可供地方小厂改造旧轧机时参考外,还对进一步研制新型高刚度轧机有参考价值。 In this paper, the main problems existing in the old rolling mill are briefly described. According to the principle of combining the short stress line with the prestress, a small high rigidity mill is designed successfully. The structure of the mill and its main features are introduced, and the economic benefits since the machine was put into operation are introduced. This article in addition to small mill for the transformation of the old mill when the reference, but also further development of new high rigidity mill has reference value.
