    Description

     Currently, there are two type of ramming masses used in the glass furnace. One is AZS ramming mass and the other is zirconite ramming mass. 
    AZS ramming mass is made of crushed fused cast AZS brick particles as aggregate materials mixed with other auxiliary materials. It reserves the advantage of fused cast AZS bricks such as good corrosion resistance to molten glass and metals, low porosity and stable properties. 
    Zirconite ramming mass is made by adding a certain portion of crushed sintered zircon brick particles into the zircon clay and then adding other auxiliary materials. It has high refractoriness and good corrosion resistance to glass liquid. 
    During construction, the two types of zircon ramming masses are mixed by adding a proportion of water. After mixed evenly, the ramming mass is wet and loose. Then it is rammed and sintered into a rigid unitary body. It contains no phosphoric acid and is safer and more convenient. 
    Although the two zircon ramming masses both have good corrosion resistance to molten glass and almost no pollution to glass liquid, proper choice should be made according to the properties of the glass produced. 
    The main difference between the two ramming masses is the content of Al2O3 and the porosity. Since there are joints between the paving bricks, glass liquid will penetrate into the ramming mass through the joints. Therefore, the ramming mass should have good corrosion resistance to the molten glass. 
    AZS ramming mass can form a layer of Al2O3 layer when contacting the alkali glass liquid, which prevents ramming mass from melting in the glass liquid. The interface layer has passivation characteristics and it has good abrasive resistance and corrosion resistance. Since zirconite ramming mass contains no alumina, when it contacts alkali glass liquid, it will not form a protective layer. So, it is easy to be broken down. 
    In short, the two have similar corrosion resistance. Since zirconite ramming mass has a content of Al2O3 and two have different porosity, AZS ramming mass is suitable to the bottom ramming layer of soda-lime-silica glass, vacuum glass and other alkali glass furnaces, while zirconite ramming mass is more suitable to the bottom ramming layer of weak alkaline borosilicate glass furnaces.
