Product Details

Fused cast AZS blocks


Fused cast AZS Block is also known as fused zirconia corundum block,named as electrocast AZS refractory blocks and the abbreviated is AZS, according to the three chemical components of the Al2O3-ZrO2-SiO2 and Al2O3 takes A, ZrO2 takes Z, SiO2 takes S. 

Fused Cast AZS block takes an important role in the Glass Furnace, which are mainly made of zircon and industrial alumina with little zirconium rich sand (in order to increase the purity of ZrO2), soda ash, and borax. According to the different atmospheres during melting, there are two methods: reduction melting and oxidation melting. Currently, the main method is oxidation. The oxidation melting method can remove the pollution caused by graphite electrodes in the molten liquid, with a low carbon content (0.005% 0.02%), reduce the bubble content in the glass, and improve the quality of the glass liquid. 


Character:


1.Compact micro-structure.

2.High strength, compression resistance

3.Good erosion resistance to molten glass

4.Good thermal shock resistance,high compression resistance

5.Size can be made according to the actual glass furnace

According to the different of ZrO2 purity,there are three different material grades and they are AZS-33 #, AZS-36 # and AZS-41#.

Company Profile

Great winner ceramic is founded in 1998,which has more than 20 years history. Our factory locates in Zichuan industry park, Zibo city, Shandong province which is the biggest refractory material production base of China. We mainly focus on producing the refractory material products which can be used in the glass furnace and steel industry.

Comparing with other factories products, in our factory the glass refractory products can use more time and in this way can save more cost for the glass factory. Our submerged entry nozzle can work continuously at least four hours and is welcome by many big steel factories. What we are trying to do now is helping the glass factory and steel factory to save more cost. This is from our customers’ feedback. We have enough confidence with our product quality.
