The size, quality and production effect of the furnace vary depending on the type of glass produced. By comparing and analyzing the performance of refractory materials, the use effect of refractory product materials is studied. At present, refractories materials that are resistant to high-temperature glass liquid corrosion can effectively improve the weak links of the melting furnace. The following will analyze several typical refractory products materials based on this characteristic.
1: Melting and casting materials:
Melting and casting materials are distributed in a certain ratio. Through high-temperature melting, sufficient casting is achieved to ensure the use effect of refractory materials. The materials after melting and casting are mainly composed of alumina, zirconia and melting and casting materials. Among them, zirconia is mainly used in the production of electric melting furnaces for specific glasses. At present, this type of melting and casting materials is mainly used in the world, which has a strong influence. my country's refractories materials are formed by casting after the fusion of high-temperature materials with a certain ratio. The refractories materials of glass kilns are mainly zirconium corundum, alumina, etc. Use glass liquid adjustment in different spaces to determine the main production range of oxidized products. my country mainly uses fused cast refractory materials, and there are few large-scale ones.
2: Silica brick materials
Silica brick materials are the main refractory products used in glass kilns, and are mainly used in the external flame parts of the melting furnace. The quality of silica bricks is ensured by the normal operation of silica bricks. However, the heating of silica bricks is not very uniform, and the non-refractory parts are prone to reduce the service life. The selection of high-quality silica bricks and more high-temperature resistant refractory product materials is an issue that needs to be studied in my country's glass kiln industry.
3: Magnesium metal refractory materials
Glass kilns use magnesium metal materials, which are mainly composed of fused magnesium bricks and alloy magnesium bricks. Through heat storage and reserve, the standard scale of dosage is improved, and the service life of my country's glass kilns is improved. However, the metal will be consumed by long-term use of temperature, which is the main weak link of this magnesium metal oxide material in the use of glass kilns.
