Universal rolling mill overview  

The universal rolling mill is composed of a pair of horizontal rolls and a pair of vertical rolls to form the main frame. The axes of the four rolls are in a plane, the horizontal roll is the driving roll, and the vertical roll is the driven roll. The rolling stock can be processed on four sides, and the two-high horizontal rolling mill is used as an auxiliary frame.

Universal rolling mill is mainly used to roll various types of steel, such as: H-beam, rail, I-beam, channel steel, sheet pile, U-beam, L-beam, unequal angle steel and other types of steel. Because it is suitable for rolling a variety of steel, it is named "universal rolling mill".

The development history of universal rolling mill

The world's first universal rolling mill was built in Luxembourg's Arbed plant in 1902, but the I-beam with wider flanges rolled at that time still had a slope. In 1908, the first wide-flange H-beam steel mill was built in Bethlehem, USA according to the Green rolling method. In 1914, the German Pein Company also used the same method to build the Pein H-beam plant; in 1955, the European Coal and Steel Joint Venture developed the IPE steel beam series, and in 1957, the German Pein H-beam plant produced the first batch of IPE steel beams. But until 1970, I-beam production still accounted for a large proportion.

Since the 1960s, with the development of the world iron and steel industry, the universal rolling mill has developed rapidly, and the steel industry in most countries is actively preparing to build a new type of universal rolling mill. Countries make full use of the original large rolling mills and rail and beam rolling mills for technical transformation, which is widely used in Japan. During about 10 years from 1961 to 1972, Japan has transformed three large factories and one rail and beam factory successively. . A lot of time was spent on technical transformations and improvements to new technologies. By 1965, Japan had produced a large number of H-beams. By the end of the 1960s, there were 74 sets of large rolling mills in the world, 24 sets of rail beam rolling mills, and 12 sets of wide-beam steel beam rolling mills.

In China, due to policy and technical reasons, the application history of universal rolling mills in China is very short, and China has not been able to produce high-quality hot-rolled H-beams for a long time. In July 1998, after the universal rolling mill introduced by Maanshan Iron and Steel from abroad rolled the first H-beam in China, H-beam, a new type of steel, began to enter a new era in China.

Since then, Laigang, Rizhao, Jinxi and other section steel mills have successively introduced foreign universal rolling mills. By 2007, the number of universal rolling mills in China showed a rapid increase, and most of the equipment was imported from abroad at high prices. Among them, in 2003, the 300H section steel production line designed and manufactured by Tianjin Zhongzhong Technology Engineering Co., Ltd. was put into operation, marking the official operation of the universal rolling mill independently developed by China. Since then, the universal rolling mills of Dalian Zhengda, Tangshan Shengda, Anshan Zizhu and Anshan Baode steel mills designed and manufactured by Tianjin Zhongzhong have been put into operation one after another, marking that the domestic equipment from 100~600H steel universal rolling mills can be completely localization.
