Various parts of glass furnace refractories and precautions
The quality of refractories in the glass industry is of great importance for improving the quality of glass products, saving fuel, extending kiln life, and reducing glass production costs. Refractory materials are the material basis of glass furnaces, which have a great impact on the overall efficiency of the kiln and must be properly selected. Different parts of the pool work in different states, the performance requirements of refractory materials are also different. The basic requirements for refractories for glass melting furnaces are as follows: adequate serviceability, such as high temperature performance, chemical stability, hot and cold stability, volume stability and mechanical strength; high refractoriness; Glass liquid is not polluted or has minimal pollution; prolongs service life as much as possible; no contact reaction between refractory materials of different materials built up at high temperature; precise pattern and size with minimal loss of heat and radiation; Use high-quality materials, other parts of the use of general materials.
Glass kiln lining the main damage to the main chemical erosion, and the role of thermal stress. The extent of chemical attack, the speed and the use of parts, kiln temperature, melting glass varieties are closely related, of course, the quality of the lining itself is also crucial. The nature of the refractory used in the glass kiln has a very significant effect on the operation of the glass kiln and on the quality of the glass. The use of poor quality refractory materials not only causes frequent shutdowns, limited melting temperatures and kiln output, but also shortens the life of the kiln and at the same time causes various defects (streaks, stones) in the glass, Reduce the quality of the glass.
