Glass kiln silica brick erosion damageSilica bricks have poor corrosion resistance to alkaline oxides and are often used in the upper structure of tank kilns. Usually, the corrosive agent in tank kilns is mainly r2O (alkali metal oxides). After a large amount of R2O e··· ...

Which refractory bricks are good for glass kilns depends on the specific structure of the kiln, working conditions and required refractory performance. The following are some common types of refractory bricks, which are widely used in glass kilns: 1. Silica bricks: ma··· ...

The tank kiln is the core equipment of the glass factory and is generally cold repaired once every few years. The reasons for cold repair under normal circumstances are as follows. A. The refractory materials in contact with the molten glass are seriously damaged and ··· ...

Before replacing the flow channel bricks of the glass kiln, Hongtai technical masterthe suggest the following preparations that need to be made:1. Determine the replacement part and prepare various bricks as needed, generally including: a set of flow channel side wall··· ...

The raw materials used for sintered zirconium corundum (AZS) bricks (hereinafter referred to as AZS bricks) are alumina and zircon. Generally, the ZrO2 content is controlled at 15%~30%. The main crystal phase components are mullite, corundum and baddeleyite. Under the··· ...

Chrome corundum bricks refer to corundum refractory products containing Cr2O3. At high temperatures, Cr2O3 and Al2O3 form a continuous solid solution, so the high-temperature performance of chrome corundum products is better than that of pure corundum products. Chrome··· ...

Glass furnaces are vital thermal equipment in glass plants. A single furnace can account for over 50% of the total fixed asset investment of an entire glass production line.Since the invention of AZS electric furnace bricks, almost all furnace pool wall bricks have be··· ...

Zirconia-based refractory materials are fire-resistant products made from natural zircon sand (ZrSiO4). They belong to acidic refractories, characterized by strong slag resistance, small thermal expansion rate, decreasing thermal conductivity with increasing temperatu··· ...

Reasonable use and maintenance of the regenerator system is one of the most important tasks for glass enterprises after they are put into production. Whether its use and maintenance are reasonable and optimal, there is no numerical standard. Its irrationality will tak··· ...

After a long-term high temperature operation of the glass melting furnace, the refractory brick kiln lining and various equipment used have experienced different degrees of aging. In particular, the checker bricks of the regenerator were seriously damaged and blocked,··· ...
