High-purity Mullite Improves Glass Furnace Lining Erosion Resistance and Service Life

Project Overview

Our client is a large glass manufacturing enterprise, mainly producing float glass and architectural glass. The glass melting furnace runs continuously at high temperature for a long time, requiring refractory raw materials with excellent alkali resistance and molten glass erosion resistance.

Customer Pain Points

Traditional refractory materials are vulnerable to chemical corrosion and penetration by high-temperature molten glass and alkali volatile substances. The furnace lining is easy to be damaged and thinned, leading to frequent furnace shutdown maintenance and restricting long-term stable production.

Our Solution

We supply high-density and high-purity mullite raw materials with low thermal expansion and strong alkali corrosion resistance. As the key aggregate for glass furnace castables and precast bricks, it forms a stable high-temperature crystal phase, effectively isolating molten glass erosion and chemical reaction penetration.

Application Effect

The overall corrosion resistance and structural stability of the furnace lining are significantly enhanced. The furnace maintenance cycle is effectively extended, unplanned shutdown losses are reduced, and the continuous operation efficiency and production capacity of the glass melting furnace are greatly improved.

Project Summary

Our mullite series products feature stable quality and excellent high-temperature chemical stability. They are widely applicable to glass melting furnaces, flow channels and tank furnace linings, providing long-life refractory raw material support for the glass industry.
