Solution Overview
Problem
Traditional metallic anchor systems used for securing refractory linings to vessel walls degrade in corrosive environments, leading to reduced thermal insulation, increased abrasion and erosion, and the need for costly repairs and replacements.
Innovation Solution
A dual component anchor system comprising a non-metallic anchor head and a metallic stud base, where the anchor head is made of materials like ceramics and the stud base is made of materials like carbon or alloy steel, providing corrosion resistance while maintaining modularity and weld strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional metallic anchor systems are used for securing refractory linings, then weld strength and structural integrity are achieved, but corrosion resistance deteriorates in corrosive environments
Solution Approach 1:
The anchor system combines a non-metallic anchor head (made of corrosion-resistant materials such as ceramic, polymer, or concrete) with a metallic stud base (made of carbon steel or alloy steel). This composite structure allows the non-metallic portion to resist corrosion while the metallic stud base provides weld strength and structural integrity for securing the refractory lining to the vessel wall.
2Adaptability or versatility
If single component anchoring systems are used to replicate hexmetal systems, then modularity is achieved, but corrosion resistance deteriorates due to exposure of metallic components
Solution Approach 1:
The single component anchor is designed as a composite object with a non-metallic anchor head that provides corrosion resistance and a metallic stud base that enables welding. This allows the modular single component system to maintain both its adaptability for various installations and its reliability through corrosion resistance in harsh environments.
3Strength
If traditional metallic anchor systems are used, then structural strength is maintained, but thermal insulation deteriorates due to increased thermal conduction
Solution Approach 1:
The non-metallic anchor head material (ceramic, polymer, or concrete) has lower thermal conductivity compared to traditional metallic anchors. This composite structure maintains structural strength through the welded metallic stud base while reducing thermal conduction through the anchor itself, thereby improving the overall thermal insulation performance of the refractory lining system.
4Duration of action of stationary object
If traditional metallic anchor systems are used, then durability is achieved, but erosion resistance deteriorates in corrosive and abrasive environments
Solution Approach 1:
The non-metallic anchor head material is selected from corrosion and erosion-resistant materials such as ceramic, polymer, or concrete. This composite structure protects the anchor from degradation by corrosive and abrasive materials in the vessel environment, while the metallic stud base remains protected from direct exposure to these harmful factors, thereby extending the overall durability and service life of the anchoring system.
