Solution Overview

Problem

The existing methods for starting and stopping multi-strand continuous casting machines are time-consuming and hazardous due to the high number of plug drives, which are prone to damage and require dangerous assembly on hot equipment.

Innovation Solution

A multi-plug drive system that allows independent opening and closing of multiple plugs, attached to a beam for easy assembly and disassembly, with electrical connections made via a single harness, and transported using a manipulator to reduce assembly time and risk of injury.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple separate plug drives are mounted on the casting distributor, then each plug can be controlled independently, but the assembly and disassembly time increases significantly and the risk of damage and injury increases

Engineering Contradiction:
ImproveIndependent plug controlVSAvoidAssembly and disassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent combines multiple separate plug drives into a single integrated multi-plug drive unit that can control multiple plugs simultaneously. This merging approach allows independent control of each plug while reducing the number of separate assembly operations required, thereby decreasing assembly and disassembly time without sacrificing operational independence.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multi-plug drive is designed as a universal unit capable of controlling multiple plugs through a single interface. This multi-functional design enables one assembly operation to install multiple plug drives at once, reducing the overall assembly time while maintaining the ability to independently control each individual plug during operation.

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

2Ease of operation

If multiple separate plug drives are assembled on the hot casting distributor, then each plug can be controlled, but the risk of injury to assembly personnel increases due to exposure to hot equipment

Engineering Contradiction:
ImprovePlug control capabilityVSAvoidRisk of injury from hot equipment
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

By merging multiple plug drives into a single multi-plug drive unit, the patent reduces the number of separate assembly operations required on the hot casting distributor. Assembly personnel need to perform fewer hot-work operations, thereby reducing cumulative exposure time to hot equipment and lowering the overall risk of injury.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multi-plug drive is designed as a pre-assembled unit with multiple plugs already attached in a controlled environment before being installed on the hot casting distributor. This preliminary assembly approach allows workers to complete the assembly process in a safer, cooler environment and then simply attach the complete unit to the distributor, minimizing exposure to hot equipment.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If multiple separate plug drives are used on the casting distributor, then each outlet can be controlled, but the risk of damage to the plug drives increases during transport and storage

Engineering Contradiction:
ImproveOutlet controlVSAvoidRisk of damage during transport
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges multiple plug drives into a single robust multi-plug drive unit with a unified structure. This consolidation provides better mechanical protection for the individual plug drives during transport and storage, as they are no longer separate vulnerable components but are instead integrated into a single protected assembly that can be handled more safely.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If multiple separate plug drives are assembled on the casting distributor, then complete plug control is achieved, but the complexity of assembly and electrical connections increases

Engineering Contradiction:
ImprovePlug controlVSAvoidAssembly complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple plug drives into a single multi-plug drive unit with integrated electrical connections. This merging approach reduces the number of separate electrical harnesses and connection points required, thereby simplifying the overall assembly process and reducing electrical complexity while maintaining the ability to independently control each outlet.

Inventive Principle:
Principle #5Merging (Combining)
