27 m² AZS Bricks for Electric Fusion Kilns

This product is a complete set of AZS refractory bricks designed specifically for fully electric glass melting furnaces in the 27-square-meter class. Tailored to the unique operating conditions of electric melting furnaces—such as vertical melting, cold-top coverage, and electric heating electrode zones—it offers a full range of custom brick types for the tank walls, tank bottom, electrode bricks, and flow channels. It combines the comprehensive advantages of high electrical insulation compatibility, resistance to severe corrosion, and extended furnace service life.

Key Features:

Complete Furnace-Matching Design: Based on the melting tank structure of 27-square-meter electric melting furnaces, a complete set of AZS brick configurations is pre-designed to cover all critical contact areas, including the melting tank walls, tank bottom lining, electrode zone protective bricks, flow channels, and risers. The design ensures uniform material composition and tight brick joints.

Electrode Zone Safety Protection: Fully accounting for the harsh environment around electrodes—including high temperatures, high current density, and intense molten glass convection—we provide specialized protective bricks and custom-shaped perforated bricks. These offer excellent resistance to high-temperature erosion and superior insulation compatibility, ensuring the long-term safe operation of the electrode system.

High Corrosion Resistance and Long Service Life: Electric melting furnaces primarily process specialty glasses such as borosilicate and high-alkali glass. The dense protective layer of AZS-33#/36#, with its high zirconia content, effectively resists chemical corrosion and mechanical erosion from highly corrosive molten glass, significantly extending the furnace’s service life.

Stable Cold-Top Operation with Low Contamination: The oxidation process controls glass phase leaching to an extremely low level, eliminating contamination of the glass melt by scale and bubbles at the material source. This is highly compatible with the cold-top melting process of electric melting furnaces, ensuring high-quality glass production.

Precision Machining for Rapid Installation: All bricks undergo CNC precision grinding, ensuring excellent dimensional interchangeability and high on-site masonry efficiency. They are particularly suitable for construction within the compact internal spaces of all-electric melting furnaces, shortening cold repair durations.

Suitable Furnace Types:

Various all-electric glass melting furnaces with a capacity of approximately 27 square meters, suitable for melting specialty glasses such as borosilicate glass, high-alumina glass, high-alkali container glass, optical glass, and solar glass tubes.
