Every glass producer is forced to improve product quality, but at the same time reduce costs. Possible ways to increase cost effectiveness, for example, are to reduce the production eject parts and prolong the campaign length of a glass tank. The quality and corrosion resistance of refractory bricks has been improved year-by-year. The only way to improve the corrosion resistance of glass tank parts that are exposed to heavy wear is to protect them with metal. Only a few metals can withstand the high temperatures required for the production of glass. This paper shows a comparison of the corrosion resistance of different metals and AZS material to the most commonly used glass melts, and shows how limited the possibilities are.
