The alkali-free high aluminum borosilicate glass melting temperature is very high. The service life of glass furnace is greatly affected by the melting temperature and process stability. After long-term production practice, it is found that it can achieve the purpose of improving the stability of the melting process and effectively cooling the weak parts of the furnace by stabilizing the state of the material pile, pushing in the electrode brick in time, optimizing the structure of cooling system and other measures, so as to slow down the erosion rate and prolong the service life of furnace.
