Modular Hot Rolling Train for Rapid Product Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling trains have a fixed configuration, limiting the optimization of the manufacturing process and making it difficult to adjust to different finished products, process designs, dimensions, materials, and quality requirements.
Innovation Solution
A modular rolling train is subdivided into discrete units, each comprising interchangeable modules that can be exchanged using transport equipment, allowing for rapid adjustment of the rolling train and process control to produce different finished products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rolling train has a fixed configuration, then the structural stability is maintained, but the adaptability to different finished products, process designs, dimensions, materials and quality requirements deteriorates
Solution Approach 1:
The rolling train is divided into discrete units, each comprising multiple modules that can be independently exchanged. This segmentation allows the system to maintain overall structural stability while enabling flexible reconfiguration by swapping individual modules within discrete units, thereby improving adaptability without proportionally increasing overall system complexity.
Solution Approach 2:
The rolling train transitions from a static fixed configuration to a dynamic reconfigurable system where modules can be exchanged based on production requirements. The transport equipment enables dynamic reconfiguration of the rolling train by laterally introducing or removing modules from discrete units, allowing the system to adapt to different products while maintaining manageable complexity through standardized interfaces.
2Adaptability or versatility
If the rolling train is adjusted by rebuilding, then the adaptability to different products is improved, but the loss of time and productivity deteriorates
Solution Approach 1:
Modules are pre-assembled within discrete units and standardized for quick exchange. The transport equipment is prepared to laterally introduce or remove modules as needed, eliminating the need for time-consuming on-site rebuilding operations. This preliminary preparation of modular components significantly reduces the time required to adjust the rolling train for different products.
Solution Approach 2:
The traditional mechanical rebuilding process is replaced by an automated module exchange system using transport equipment. Instead of manually disassembling and reassembling rolling train components, the system uses lateral transport mechanisms to quickly swap out entire modules, dramatically reducing adjustment time while maintaining full adaptability to different product requirements.
3Ease of operation
If the rolling train is subdivided into discrete units with interchangeable modules, then the ease of operation and adaptability are improved, but the device complexity increases
Solution Approach 1:
Standardized interfaces are implemented across all discrete units and modules, creating a universal exchange system. The same transport equipment and connection protocols can be used throughout the rolling train, allowing modules to be exchanged across different discrete units. This universality simplifies operation despite the increased number of components, as operators work with consistent standardized elements rather than unique custom interfaces.

AI summary
A modular rolling train, particularly a hot rolling train, preferably in conjunction with an upstream casting facility, and a method for operating a modular rolling train are described. The rolling train is standardized and modularized by dividing the rolling train into discrete units n and by modularization of the discrete units. The rolling train can be flexibly adapted to new requirements by exchanging a module.
