Ten-roller rolling mill with horizontal rack

Abstract

The invention relates to a ten-roller rolling mill with a horizontal rack. The ten-roller rolling mill comprises a rack, an upper support roller, an upper intermediate roller, an upper horizontal rack, a lower horizontal rack, a lower intermediate roller, a lower support roller, side supports and a side support adjusting mechanism, wherein an upper working roller, two side supports and the side support adjusting mechanism are mounted in the upper horizontal rack; a lower working roller, two side supports and the side support adjusting mechanism are mounted in the lower horizontal rack; and the upper horizontal rack and the lower horizontal rack convert side support force of the upper working roller and the lower working roller into internal force of the upper horizontal rack and the lower horizontal rack separately, and the upper horizontal rack is equivalent to an upper working roller bearing seat to move up and down in a rack window along with rolling reduction. According to the scheme that the horizontal racks are introduced to replace complex, bloated and difficult-to-adjust side supports of an eighteen-roller rolling mill, on the premise that the horizontal rigidity of the working rollers is guaranteed, the structures and the adjusting process of the side supports are greatly simplified, the maintenance and comprehensive production cost is greatly reduced, the use requirements of the majority of users are met, and the popularization prospect is broad.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a ten-high rolling mill with a horizontal stand. Background technique [0002] With the rapid development of industry, the production of metal strips is developing in the direction of high strength, low thickness, high precision, etc., thus the multi-roll rolling mill came into being. In recent decades, multi-roll mills have been continuously developed and improved due to their advantages such as small diameter of work rolls, high mill rigidity, small size, and light weight. Among them, 18-roll mills are used for continuous cold rolling of strip steel, stainless steel, high-strength steel, etc. important model. [0003] The core technology of the eighteen-high rolling mill is to add four sets of side support devices on the basis of the traditional six-high HC rolling mill. That is, the small-diameter work roll is supported by the side support device arranged in ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a ten-high rolling mill with a horizontal stand, which solves the problems of the existing eighteen-high rolling mill with bloated and complex structure, difficulty in adjustment, and insufficient rigidity of the side support of the simplified ten-high rolling mill by introducing a horizontal stand. question
