Composite Refractory Raw Materials Improve Anti-corrosion Performance of Aluminum Electrolytic Cell Lining

Project Overview

Our client is a large non-ferrous aluminum smelting enterprise. The aluminum electrolytic cell operates stably under high temperature and strong corrosive environment for a long time, putting forward high requirements on the fluoride corrosion resistance and penetration resistance of the cell lining refractory materials.

Customer Pain Points

Single traditional refractory raw material has poor resistance to cryolite molten salt corrosion and aluminum liquid penetration. The cell lining is easy to swell, crack and peel off, resulting in shortened equipment overhaul cycle and increased comprehensive production cost of electrolytic aluminum.

Our Solution

We adopt a composite formula of high-purity white fused alumina and mullite. The two raw materials complement each other in performance, forming a dense and stable high-temperature resistant structure. It effectively resists molten salt erosion and liquid aluminum penetration, and improves the overall structural stability of the electrolytic cell lining.

Application Effect

The corrosion and penetration resistance of the electrolytic cell lining are greatly enhanced, the damage rate of the refractory lining is significantly reduced, and the equipment overhaul cycle is effectively extended. The production stability of electrolytic aluminum is improved, and the enterprise’s operation and maintenance costs are reduced.

Project Summary

Our matched composite refractory raw materials have stable performance and strong targeted adaptability. They are specially suitable for high-corrosion working conditions of aluminum electrolytic cells, providing high-quality and long-life refractory raw material solutions for the non-ferrous metal industry.
