随着铁路运输和环形件生产技术的发展,1842年英国制造出世界上第一台环形件轧机,用来生产火车轮箍。从此,火车轮箍的生产进入了轧制工艺的新阶段。厉来悠国的克虏伯于1849年做了第一次生产火车轮箍的尝试,并于1853～1854年制造出德国第一台环形件轧机。到十九世纪末二十世纪初,苏联、美国、日本等国,相继采用轧制方法生产火车轮箍。然而,随着工业的发展,自本世纪五十年代以来,火车轮箍的需要量急剧下降,各工业 With the development of rail transport and ring production technology, the United Kingdom made the world’s first ring rolling mill in 1842 to produce train wheels. Since then, the production of train wheels has entered a new phase of the rolling process. In 1949, Krupp made the first attempt to produce train wheels and in 1853 to 1854 manufactured the first German ring rolling mill. By the end of the nineteenth century, the twentieth century, the Soviet Union, the United States, Japan and other countries, have adopted the rolling method to produce train wheels. However, with the development of industry, since the 1950s, the demand for train wheels has dropped sharply. As a result, various industries
