The micro-structure of fused cast AZS block has a big effect on the properties and performance of fused cast AZS block. The main crystal phase of fused cast AZS consists of corundum, baddeleyite and glass phase. Generally, corundum and baddeleyite exist in eutectic crystals, which contribute greatly...

Refractories are the main materials used in the glass fu aces and have big influence on the service life of glass fu aces, the quality of glass, the energy consumption and the cost. The development of the manufacturing technology of glass greatly depends on the the development of refractory technolo...

Fused cast refractory is a special type of refractory made by melting the raw materials in the electric arc fu ace, pouring the melt into a mold and cooling the melt to solidify. It features dense structure, good corrosion resistance, low pollution to glass and long service life. Its quality and dev...

The popular type of fu ace used for the production of E glass is the unit fu ace. More than 10 kinds of refractories are used to build to the fu ace. Fused cast AZS block Fused cast AZS 33# is mainly used in the bu er block of the melting zone and the feeder block. Dense chromium oxide brick Dense c...

The need of the glass manufacturers to maintain and improve the quality of glass and expand the service life of the glass fu ace and the impact and influence of the oxygen-fuel combustion technology, promote the improvement of refractories and development of the new refractories. Fused cast alumina ...

The quality of fused cast AZS block is related to many factors such as the chemical composition of raw materials, the melting process, the casting process and the annealing process. One of the main quality problems of the fused cast AZS block is cracking. Fused cast AZS block is mainly composed of b...

Alumina (Al2O3) refractories are the part of alumina- silica group of refractories. They differs from fireclay refractories in term of Al2O3 content and normally have Al2O3 content of more than 45 %. The raw material base for these refractories are different than the fire clay bricks. As the Al2O3 c...

The service life of the glass fu ace, energy efficiency and the quality of glass is mainly up to refractory materials. The following practices can be performed in order to select the right refractory materials and ensure longer operating life of the glass fu ace. Consistent quality The quality of th...
