A ten-high rolling mill with a horizontal stand

Abstract

The invention relates to a ten-high rolling mill with a horizontal frame, which includes a frame, an upper back-up roll, an upper middle roll, an upper horizontal frame, a lower horizontal frame, a lower middle roll, a lower back-up roll, a side support and a side support Adjustment mechanism; upper work roll, two side supports and side support adjustment mechanisms are installed in the upper horizontal frame; lower work rolls, two side supports and side support adjustment mechanisms are installed in the lower horizontal frame; upper and lower horizontal frames The side support force of the upper and lower work rolls is converted into its internal force respectively, and the upper horizontal frame is equivalent to the upper work roll bearing seat moving up and down with the reduction amount in the frame window. The present invention greatly simplifies the structure and adjustment process of the side support under the premise of ensuring the horizontal rigidity of the work roll, and greatly simplifies the maintenance and comprehensive production cost by introducing a horizontal frame to replace the complicated, bulky and difficult-to-adjust side support scheme of the eighteen-high mill. Greatly reduced, to meet the needs of the majority of users, the promotion prospects are 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 the industry, the production of metal sheets and strips develops in the direction of high strength, low thickness and high precision, and thus the multi-roll 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, large stiffness of rolling mills, small size and light weight. important models. [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 rolling mill. That is, the small-diameter work roll is supported by the side support device arranged in the tower shape, which ensures that the work roll has the ability to resist the deflection in the horizontal...
