Solution Overview

Problem

Existing profile rolling mills face challenges in maintaining process reliability due to deviations in the rolling stock's position and potential accidents during the rolling process, particularly when handling inherently rigid materials like steel profiles.

Innovation Solution

The implementation of a profile rolling mill with adjustable rolling stock guides and associated assemblies that utilize measuring devices to detect radial positions and guide bodies to correct deviations, combined with safety devices to prevent accidents, and cleaning systems to maintain cleanliness, enhances process reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixed rolling stock guides are used, then the structure is simple, but process reliability decreases due to position deviations

Engineering Contradiction:
Improveprocess reliabilityVSAvoidguide system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The rolling stock guide is designed with adjustable components that can dynamically change their position and orientation based on measured deviations of the rolling stock. The guide body can be displaced in guide direction by a displacement device, transforming a static guide system into a dynamic one that adapts to actual rolling conditions, thereby improving process reliability without excessive complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A measuring device detects the radial position of the rolling stock and provides feedback signals to a control unit. The control unit processes this information and actuates the displacement device to adjust the guide body position, creating a closed-loop feedback system that continuously corrects position deviations and maintains reliable rolling processes

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If adjustable guide bodies are implemented, then position control improves, but device complexity increases

Engineering Contradiction:
Improveposition control precisionVSAvoidguide adjustment mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical adjustment mechanisms with a more streamlined displacement device that can be controlled electronically. The measuring device and control unit work together to actuate the displacement device, substituting manual or complex mechanical adjustment with automated control, thereby achieving high position control precision while managing device complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The guide body serves multiple functions: it guides the rolling stock, its position is adjustable for precision control, and it integrates with the measuring and control systems. This multi-functionality allows a single component to achieve position control precision while the integrated system manages the complexity through coordinated operation

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If real-time measurement and adjustment systems are used, then process reliability increases, but system complexity and cost increase

Engineering Contradiction:
Improverolling process reliabilityVSAvoidmeasurement and control system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The rolling mill system performs self-diagnosis and self-correction through the measuring device that automatically detects radial position deviations and the control unit that automatically actuates the displacement device to correct guide body positioning. This self-service capability improves process reliability by enabling automatic detection and correction without external intervention, while the integrated nature of the system manages complexity through automation

Inventive Principle:
Principle #25Self-service
