Roll Chock Liner Structure for Cold Rolling Vibration and Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling mills face challenges in suppressing vibrations during the cold-rolling process, which can cause cyclic thickness changes in the steel sheet, and conventional methods using elastic members on roll chock liners suffer from wear issues.
Innovation Solution
A rolling mill configuration with a roll chock liner comprising a first liner plate, a second liner plate stacked in the rolling direction, and an elastic member interposed between them, fastened by fasteners with heads housed in dedicated openings, preventing exposure and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an elastic member is mounted on the roll chock liner to suppress vibrations, then vibration suppression is improved, but the elastic member wears out due to exposure
Solution Approach 1:
The roll chock liner is segmented into multiple liner plates stacked in the rolling direction, with the elastic member positioned between specific plates. This segmentation allows the elastic member to be protected while maintaining its vibration suppression function.
Solution Approach 2:
The elastic member is nested between the first and second liner plates, which are stacked in the rolling direction. This nesting structure protects the elastic member from exposure and wear while allowing it to function for vibration suppression.
2Device complexity
If a single liner plate is used on the roll chock, then the structure is simple, but vibration suppression is insufficient
Solution Approach 1:
The roll chock liner is constructed as a composite structure combining multiple liner plates and an elastic member. This composite structure provides both vibration suppression capability and structural integrity while maintaining reasonable complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively suppresses vibrations and prevents wear of the roll chock liner, ensuring stable rolling processes and consistent sheet thickness.
Implementation Method 1
capable of suppressing vibration during a rolling process
Implementation Method 2
an elastic member interposed between the first liner plate and the second liner plate

AI summary
A rolling mill includes a plurality of stands configured to roll a material to be rolled, wherein at least one stand, among the stands, includes: at least one pair of rolling mill rolls; a roll chock that rotatably support the rolling mill rolls; and a roll chock liner that includes a first liner plate mounted on the roll chock, a second liner plate stacked on the first liner plate in a rolling direction, and an elastic member interposed between the first liner plate and the second liner plate.
