Solution Overview

Problem

Existing profile rolling mills face challenges in achieving high-quality rolled profiles and ensuring operational safety, primarily due to the lack of individualized control over the influence of each profile roller on the rolling goods.

Innovation Solution

The implementation of a profile rolling mill design where at least one profile roller is axially adjustable and/or its rolling cones can be adjusted parallel to the axle level, allowing for precise control over the rolling process to improve profile quality and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If profile rolls are fixed in position, then the structure is simple and stable, but the quality of rolled profiles deteriorates due to inability to individually control each roll's influence

Engineering Contradiction:
Improvequality of rolled profilesVSAvoidstructure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent implements axial adjustability of profile rolls along the pass line, transforming fixed rolls into dynamically adjustable ones. This allows individual rolls to be positioned precisely to optimize their influence on the rolled material, improving profile quality while maintaining structural stability through controlled movement capabilities.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent enables individual adjustment of each profile roll's axial position, allowing local optimization of rolling parameters for different sections of the pass line. This localized control permits tailored influence of each roll on specific portions of the rolled material, enhancing overall manufacturing precision without requiring complete system redesign.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If profile rolls are individually adjustable, then the quality of rolled profiles improves, but operational reliability deteriorates due to increased adjustment complexity and potential misalignment

Engineering Contradiction:
Improvequality of rolled profilesVSAvoidoperational reliability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent incorporates measurement devices that detect the actual positions of profile rolls and provide feedback to the control system. This closed-loop control ensures that axial adjustments are accurately executed and maintained, preventing misalignment issues and enhancing operational reliability while preserving the benefits of individual roll adjustability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control system automatically manages the axial positioning of profile rolls based on predetermined parameters and real-time measurements, reducing manual intervention requirements. This self-adjusting capability minimizes human error in positioning and maintains consistent operational reliability while achieving high manufacturing precision.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If roll necks are adjusted parallel to the axial plane, then material handling improves, but device complexity increases due to additional adjustment mechanisms

Engineering Contradiction:
Improvematerial handlingVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the axial adjustment mechanism with the existing roll support structure, integrating the adjustment function into the roll stand assembly. This merging of functions allows roll neck adjustment parallel to the axial plane without requiring completely separate adjustment mechanisms, thereby improving material handling while limiting the increase in overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)
