Abstract

The invention comprises a double four-roll temper mill, comprising two rail supports, four breams, an operation side rack, a transmission side rack, a No.1 four-roll roller system, a tension measuring roller and a No.2 four-roll roller system. The two rail supports are fixed on a workshop foundation, and the operation side rack and the transmission side rack are fixed and supported on the rail supports. The operation side rack and the transmission side rack are both integrated steel casting pieces with double windows, and are connected into a whole through the four beams. The No.1 four-roll roller system and the No.2 four-roll roller system are respectively installed in corresponding rack windows. The tension measuring roller is arranged between the No.1 four-roll roller system and the No.2 four-roll roller system and is supported on the racks for detecting tension in the rollers. Secondary cold rolling and temper rolling of band steel can be implemented through the No.1 four-roll roller system, the tension measuring roller and the No.2 four-roll roller system. The double four-roller temper mill has the significant characteristics of compact structure, easy assurance in integral assembly precision, short band through time, high unit efficiency, high pass percent and the like.

Description

technical field [0001] The invention relates to a two-frame four-roller skin pass machine, in particular to a double-four-roller skin pass machine. Background technique [0002] The traditional two-stand four-roll skin pass mill is a tandem structure, that is, two sets of single-stand four-roll pass mills are arranged in series. The tandem structure brings problems such as difficult installation, difficulty in ensuring accuracy, and large floor space. Moreover, there must be a rolling room equipment between the two skin pass mills. The structure is complex and the tonnage of the equipment is large. Difficulty, reduced efficiency, and reduced yield. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a double four-roller skin pass mill, which has the remarkable characteristics of easy assurance of overall assembly accuracy, compact structure, short belt threading time, ...
