Abstract

The invention belongs to the technical field of refractory matter, and particularly relates to components of a high-stability electric smelting AZS brick. The components of the high-stability electric smelting AZS brick are characterized in that the electric smelting AZS brick is prepared from, by mass, 32-44% of zirconium dioxide, 7-15% of silicon dioxide, 0.7-1.5% of sodium oxide, 0.5-3% of yttria and 40.9-56.5% of aluminum oxide. According to the components of the high-stability electric smelting AZS brick, the phenomena that molten glass is contaminated and a brick body is corroded due to effusion of a glass phase are reduced, and therefore the glass quality is improved.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a component of high-stability fused AZS bricks. Background technique [0002] Due to technological progress in the glass industry, the service life of glass furnaces continues to increase, and the oxy-fuel combustion technology is gradually improved, which increases the temperature of the melting pool and flame space of glass furnaces, thus making the requirements for the use of refractory materials in furnaces more stringent. The high-grade production of glass products also puts forward higher requirements for the reduction of glass defects. These conditions have promoted the improvement of various properties of kiln refractory materials, especially requiring better anti-erosion performance and lower pollution to glass liquid. [0003] At high temperature, the melting pool of the glass furnace is eroded by the glass solution for a long time, resulting i...
