Rolling Method for Continuous Variable-Section Stock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling methods cannot produce rolling stock with continuous sections of different dimensions without disconnecting the sections, and they require the roll gap to be adjusted only in a no-load state, limiting flexibility and efficiency.
Innovation Solution
The roll stand is raised at a predetermined change point to introduce a stage into the rolling stock, allowing it to pass through without deformation, and the rolling process can continue either forwards or backwards, enabling adjustment to multiple target dimensions without requiring load adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire rolling stock is rolled to a first target dimension and then divided into sections, then sections with different dimensions can be produced, but the sections are no longer connected to one another
Solution Approach 1:
The roll stand is raised in advance at a predetermined change point before the rolling stock passes through, creating a step structure that allows different sections to have different dimensions while maintaining continuity. This preliminary positioning of the roll stand enables the formation of connected sections with varying dimensions without requiring division of the rolling stock.
2Ease of manufacture
If the roll gap is adjusted only in a no-load state, then the rolling process is simple to control, but production flexibility and efficiency are limited
Solution Approach 1:
The roll stand is designed to be movable and adjustable during the rolling process, allowing the roll gap to be dynamically changed while the rolling stock is being processed. This dynamic adjustment capability enables flexible production of rolling stock with multiple sections of different dimensions without requiring the rolling process to be stopped for roll gap adjustment, thereby improving productivity while maintaining control simplicity.
Applied Scientific Principles
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 method allows for the production of rolling stock with multiple sections of different dimensions, enabling deformation-free passage and flexible adjustment of roll gap settings, whether loaded or unloaded, enhancing production efficiency and flexibility.
Implementation Method 1
the roll stand is raised when the point of the rolled stock that is currently in the roll gap corresponds to the first change point, so that a first stage is introduced into the rolled stock at the first change point

AI summary
The invention relates to rolled material (1) comprising a front (2) and an end (3). The rolled material is rolled in a roll gap (9) of a roll stand (5) to a first desired measurement (d1*), beginning at the front of the rolled material (2). When the rolled material (1) is being rolled in the roll stand (5), it is continuously determined by a control computer (6), which locates the position (10) of the rolled material (1) which is currently in the roll gap (9). When the position (10) of the rolled material, which is directly in the roll gap (9), corresponds to a predetermined first modification position (4) of the rolled material (1), which is arranged between the front of the rolled material (2) and the end of the rolled material (3), the roller of the rolled material (1) ends at a first desired measurement (d1*) such that a first step (12) is introduced into the rolled material (1) on the first modification point (4).
