Some of the glass furnaces we manufacture
Glass is never merely a transparent material, but more of a spirit of guardianship—it preserves the preciousness of the present and undertakes the responsibility for the future. This material, which combines timeless texture with environmental protection properties, is solidifying t...Read more -
Fused zirconia corundum brick in the production and use of the process will appear the following three kinds of cracks:
1. Stress cracks: Fused zirconia corundum brick composition of zirconia has the largest proportion of zirconium oxide, there is a segregation in the casting process, the annealing process is difficult to release the stress uniformity, and cracks occur. (JC493 standard for such cracks have specifi...Read more -
Dimensions, Specifications and Application Positions of Fused Cast AZS Bricks
Due to the temperature gradient and compositional segregation that occur during the casting of fused cast AZS bricks from melt to cooling and forming, it is difficult to uniformly release and completely eliminate the thermal stress and structural stress of the castings during the annealing proces...Read more -
