Microstructural Features and Formation Principle of Electro - fused AZS Cast Blocks

Electro - fused AZS cast blocks are mainly composed of Al₂O₃ - ZrO₂ - SiO₂. Their unique micro - structure is formed through a high - temperature electro - fusion process. During this process, raw materials are melted at extremely high temperatures and then slowly cooled, resulting in a dense and uniform structure. This dense structure is the key to its excellent performance.

Protection Mechanism of Dense Structure Against High - temperature Wear, Chemical Erosion, and Thermal Shock Damage

The dense structure of electro - fused AZS cast blocks provides multiple protection mechanisms. In terms of high - temperature wear, the tight arrangement of crystal grains effectively resists the scouring of high - temperature glass liquid, reducing wear. Against chemical erosion, the chemical stability of its components prevents the penetration and corrosion of acidic or alkaline substances in the glass liquid. For thermal shock damage, the structure can absorb and disperse thermal stress, maintaining its integrity. According to industry data, compared with ordinary refractory materials, electro - fused AZS cast blocks can reduce wear by up to 50% under high - temperature conditions.

Analysis of Practical Application Effects in Different Parts of Glass Furnaces

Upper Structure: In the upper structure of the glass furnace, electro - fused AZS cast blocks can resist the erosion of high - temperature flue gas and dust, effectively extending the service life of the upper structure.

Side Wall: The side wall is in direct contact with the high - temperature glass liquid. The dense structure of electro - fused AZS cast blocks can prevent the penetration of the glass liquid, reducing chemical erosion and wear, and ensuring the stability of the side wall structure.

Feeding Channel: In the feeding channel, the material is subject to the impact and scouring of raw materials. Electro - fused AZS cast blocks can withstand this impact, maintaining the smoothness of the feeding channel and reducing the occurrence of blockages.

Typical Industry Cases: Comparison of Equipment Lifespan and Maintenance Cost Changes Before and After Use

In a glass manufacturing enterprise, before using electro - fused AZS cast blocks, the average service life of the glass furnace was about 2 years, and the annual maintenance cost was approximately $50,000. After using electro - fused AZS cast blocks, the service life of the furnace was extended to more than 3 years, an increase of more than 50%. At the same time, the annual maintenance cost was reduced to about $30,000, a reduction of 40%. This shows that electro - fused AZS cast blocks can significantly reduce the operating cost of enterprises.

Installation and Daily Maintenance Points: Avoid Common Mistakes and Maximize Material Performance

During installation, it is necessary to ensure a tight fit between the blocks to prevent the penetration of the glass liquid. In daily maintenance, regular inspections should be carried out to check for cracks or wear on the surface of the blocks. If any problems are found, timely repairs or replacements should be made. Avoid sudden temperature changes during the operation of the furnace to prevent thermal shock damage to the blocks.

In conclusion, electro - fused AZS cast blocks, with their unique micro - structure and excellent performance, are ideal materials for improving the wear - resistance and anti - erosion ability of glass furnaces. They can help enterprises reduce operating costs, improve production efficiency, and enhance market competitiveness.
