Requirements of Glass Refractory
2015-09-24
Refractory material which has great influence on the overall benefit of the furnace is the material basis of glass furnace. In glass industry, quality of refractory materials has great significance of improving the quality of glass products, saving fuel, prolonging the service life and reducing the cost of glass production. So, refractory must be reasonable selected, and the working condition of each part of the kiln pool is different, the requirement to the refractory is also different, such as the bottom of furnace can use fused cast AZS block 33#, however, the electrode brick must use fused cast AZS block 41#.
The basic requirements for refractory materials of glass melting furnace are as follows:
1. There must be sufficient using performance, such as high temperature performance, chemical stability, hot and cold blast crisis stability, volume stability and mechanical strength;
2. Sufficient high refractoriness; lowest pollution or no pollution to glass liquid;
3. Prolong service life as long as possible;
4. There is no contact reaction in high temperature when the different refractory material is piled up;
5. Precise style and size;
6. Severe corrosive parts adopt high quality materials; other normal parts use general refractory materials. The main principle is that reasonable matching, and service life synchronization.
