AI Technical Summary

Technical Problem

Existing aluminum-carbon composite refractory materials have large brick joints in the silica lining, resulting in weak erosion resistance and limited service life.

Method used

The combination of trapezoidal insulation bricks and contact bricks, along with mortise and tenon structures, utilizes HR-8767A alumina high-temperature resistant adhesive layer and ZrO2-Al2O3 plasma coating. The inclined surface of the contact bricks reduces brick joints and enhances adhesion, while the internal honeycomb pores reduce heat conduction.

Benefits of technology

By reducing the amount of adhesive used and enhancing the tightness of the brick joints, the corrosion resistance of the silicone-coated material was improved, extending its service life.
