Upper Space Block For Glass Melting Furnace - China

for the contacting of breast wall and crown corner

Our AZS blocks were made by the

techniques of : Oxygen bottom blowing

+ vacuum casting process, which make

the blocks more densifying to withstand

the molten glass corrosion, then the

service life of your furnace could be

improved and the quality of the glass

purified.
