Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing refractory anchors are unsuitable for anchoring liners thicker than 80 mm due to their limited height, and they fail to withstand high temperatures and abrasive environments effectively.

Innovation Solution

A refractory anchor design with an elongated mounting pin and an anchor body featuring a central portion and side sections extending above the mounting pin, incorporating an open cut-out above the pin to enhance material flow and flexibility, and a configuration that minimizes deformation and heat transfer, allowing for anchoring thick liners in high-temperature and abrasive environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If the total height of the refractory anchor is increased to anchor thicker liners, then the anchoring capability for thick liners is improved, but the resistance to deformation under load and high temperature deteriorates

Engineering Contradiction:

Improvetotal height of refractory anchorVSAvoidresistance to deformation

Core Design Contradiction:

Length of stationary objectVSStability of the object's composition

Solution Approach 1:

The anchor body is divided into multiple sections: a central portion connected to the mounting pin, and at least two side sections extending from the central portion. This segmentation allows the anchor to achieve greater total height while maintaining structural stability through the distributed configuration of sections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the anchor body are given different properties - the central portion provides structural connection to the mounting pin, while the side sections extend outward to anchor the liner. The open cut-out in the upper side of the anchor body creates a localized region that reduces heat transfer to the mounting pin while maintaining overall structural integrity.

Inventive Principle:

Principle #3Local quality

2Length of stationary object

If the total height of the refractory anchor is increased to anchor thicker liners, then the anchoring capability for thick liners is improved, but the ability to withstand high temperatures deteriorates

Engineering Contradiction:

Improvetotal height of refractory anchorVSAvoidresistance to high temperature

Core Design Contradiction:

Length of stationary objectVSTemperature

Solution Approach 1:

The open cut-out in the upper side of the anchor body acts as an intermediary feature that disrupts direct heat transfer paths from the hot liner to the mounting pin. This creates a thermal break that protects the mounting pin from excessive heat exposure while maintaining the anchor's height for thick liner application.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Length of stationary object

If the anchor body extends significantly above the mounting pin to increase height, then the anchoring capability is improved, but the risk of cavities in the lining material near the anchor increases

Engineering Contradiction:

Improvetotal height of refractory anchorVSAvoidrisk of cavities in lining material

Core Design Contradiction:

Length of stationary objectVSReliability

Solution Approach 1:

The side sections extending from the central portion create multiple anchoring points distributed across the liner thickness. This segmentation ensures that lining material flows properly around each section, reducing the risk of cavities forming in the vicinity of the anchor while achieving the necessary height for thick liner application.

Inventive Principle:
