Analysis of service of refractories in glass-melting tank furnaces

The fundamental issues of extending the period between repairs for glass-melting tank furnaces are analyzed. Based on data obtained in studying refractory brickwork after the furnace has been stopped for a cold repair and analyzing the specifics of corrosion of refractories in various structural elements, technical solutions are proposed and implemented enabling one to extend the tank furnace campaign to 7–8 years.
