Recycling of waste refractories in the glass industry

The European glass industry uses more than 100,000 tons per year on kilns with a service life of 5 to 8 years. The dismantling of these kilns will generate thousands of tons of discarded refractories, most of which will be sent to the Technical Stacking Center (CET) or proprietary dumps.Fused Cast AZS Bricks



At present, 30% to 35% of the silica bricks removed after the kiln has been used can be reused to make two kinds of silica bricks, including the silicon wedge bricks and lightweight thermal insulation used in the working pool or regenerator roof. Silicon bricks. The former European factory that recycles and reuses refractory materials is specialized in the treatment of waste refractories from the glass industry, iron and steel industry, incinerators and chemical industry, and the recovery rate reaches 90%.

A glass company cuts the wall of the kiln's melting pool as a whole, succeeded in using the effective part of the pool wall, and removed the glass adhered on the surface of the used AZS brick, and cracked the brick with a method of quenching, broken and grinded. After screening, different size aggregates and fines are obtained to produce cheap high-performance castables and iron channels.
