Glass production employs a continuous high-temperature melting and drawing process. The melting furnace maintains a high-temperature environment for a long time, and the lining must withstand continuous attack from highly alkaline containing glass melt and structural stress caused by long-term thermal loads. This places high requirements on the refractories, in terms of resistances to corrosion and penetration of glass melt, as well as high-temperature structural stability. The quality of the adopted raw materials directly determines service life of the melting furnace and the quality of glass products.
