Glass melting furnace is a thermal equipment for melting glass. It usually uses refractory materials to form the working layer. It uses the heat generated by burning chemical energy, electric energy or other energy sources to create a controllable high-temperature environment (distribution and atmosphere) to make the glass batch material Through the process of energy transfer, mass transfer and momentum transfer in the base, physical and chemical changes are completed. After the stages of melting, clarification, homogenization and cooling, it provides a certain amount and quality of molten glass for production.
There are many classification methods for glass kilns, such as classification by environment, energy use, continuous classification according to the process, and classification according to the form of flame flow in the kiln, and so on. What we often say is generally divided into: float glass furnace, flat glass furnace, vertical lead glass furnace, calendered glass furnace, drawing tank furnace, etc. according to the forming method.
Combined with the characteristics of the glass industry, the refractory materials used in the glass furnace must meet the following points:
1.Meet the necessary high temperature performance, chemical stability, thermal stability, volume stability and mechanical strength.
2.Does not pollute the molten glass, and has little effect on the quality of the molten glass;
3.The ruler may have a long service life;
4.Between the refractory materials of different materials that are laid together, there will be no contact reaction at high temperatures;
5.The ruler may reduce the amount of material and heat loss;
6.High-quality materials should be used for the easily damaged parts, and general materials can be used for other parts, so as to achieve reasonable configuration and synchronization of kiln age.
