cover block made from AZS 33AZS-33 is characterized by its excellent corrosion resistance against molten glass due to its low exudation and blistering rate. It is usually used in the sections contacting directly with the liquid glass such as the sidewall and paving; and the superstructures such as breast wall, port and tuckstone, etc.
