一、概述早在十九世纪末期,人们就对楔形模横轧工艺的工作原理有过不太完善的介绍,但由于当时的技术水平所限,这种工艺方法仍一直处于停滞状态。以后曾进行过一些零星的研究,但没有什么进展。直到本世纪六十年代,由于民德和捷克斯洛伐克对其工艺、机器和模具进行了较为全面的研究并发展了相应的装置和设备之后,才使这种工艺在工业中得到使用。目前,除了民德、捷克斯洛伐克外,苏联、日本、 First, an overview As early as the late nineteenth century, people on the wedge-shaped cross-rolling process works have been less than perfect presentation, but due to the technical level of the time constraints, this process has remained at a standstill. There have been some sporadic studies in the future, but no progress has been made. It was not until the 1960s that Grenad and Czechoslovakia had made a comprehensive study of their processes, machines and molds and developed corresponding installations and equipment before making such processes available to industry. At present, except for Germany, Czechoslovakia, the Soviet Union, Japan,
