    Fused Cast AZS Brick as an important role used in Glass Furnace is made of pure alumina powder and zircon sand and is composed of three main chemical components of Al2O3, ZrO2 and SiO2. Fused Cast AZS Brick is manufactured through casting technology in RS Professional Factory.
    AZS Bricks, Alumina-Zirconia-Silica (AZS) refractories, belong to sintered ZrO2_Al2O3_SiO2 products family along with Zircon Mullite, Bonded AZS, Zirconia Corundum, and Rebonded Fused Mullite bricks. Sintered ZrO2-Al2O3_SiO2 products such as AZS have good resistance to alkali vapor and thermal shock. Mainly used in glass furnaces, they can withstand aggressive conditions in contact with molten glass. 
    Fused Cast AZS Refractory bricks products of AZS series of oxidation are made of qualified raw materials by using specially designed electric arch furnace and undergoing the casting process through long-arc melting furnace and oxidation. This kind of casting process hardly suffers any carbon pollution from the electrode.

    Properties Of Fused Cast AZS Brick
    Dense micro structure
    Strong resistance for high temperature and glass liquid
    Good thermal shock resistance

    Manufacturing Process of AZS Brick
    There are four steps for manufacturing process of AZS Brick including melting of raw materials, casting, cooling and cutting.

    Prefer proportions of 1:1 zircon sand and industrial alumina powder and add few volume of NaZO, B20 agent of fusion after mix perfectly through smelting and pouring into mould at high temperature of 1900~2000℃ resulting the fused cast brick contained 33% ZrO2 content. On the base, adopt part of desilicication zircon sand as the raw material to make the fused cast brick with 36%~41% ZrO2 content.
    If the casting speed is too fast and the temperature is too high, the air in the mold will not be exhausted and the bottom of the mold will be broken, which will waste the casting time. So it is very important to control the casting temperature and speed.
    The quality of AZS Brick is subjected by the quality of raw materials and manufacturing technology. Rongsheng Refractory as a professional fused cast AZS Brick manufacturer can provide customers with high quality AZS Brick at low price based on our professional engineers, advanced technology and equipment.

    Due to the application of such casting technology and high-purity raw materials, AZS Brick of oxidated electrocast zirconia-alumina products are possessed of special and high quality of erosion resistance of glass liquids. In addition, it has the minimal pollution to the glass.
    AZS Brick-33 
    AZS Brick-33 are excellent in preventing the pollution of glass liquids. The possibility of causing glass stones, bubbles and basic glass phase precipitation is quite slim. It can be applied to the upper structure of melting pool, the tank wall corner tiles,paving bricks and other approaches as well.
    AZS Brick-36 
    AZS Brick-36 are the standard Fused Cast AZS Refractory bricks brick which boasts of the quality of particularly high corrosion resistance of glass liquids and low pollution. More than that, it has a balanced performance in the above two aspects. It can be applied to the direct access of glass furnace and glass liquids, such as melting tank wall corner tiles, paving bricks and charging door.
    AZS Brick-41
    AZS Brick-41 are the best oxidated zircon corundum brick which possesses the quality of highest corrosion resistance of glass liquids and excellent low pollution of glass liquids. It can be applied to the locations of glass furnace which requires particularly high corrosion endurance, such as full-fused furnace, liquid pumps, furnace ridge, bubbling brick and bricks of charging door corners.
    Besides, the fused cast AZS Bricks can be devied into different types according its casting techniques, PT [normal casting], QX [tilt casting ] , ZWS [reinforced casting ] and WS [void-free casting]. 
    WS while casting, the casting size is bigger than that is required. Most of the voids concentrate in the header which is subsequently cut off with a diamond saw, and then the Brick in required size is left, most used in side wall and flow.
    PT The brick made by normal casting has normal shrinkage void; it is often used in the upper structure of furnace and the interface parts which touch molten glass.
    ZWS while casting, the casting size is bigger than it is required. Most of the voids concentrate in the header which is subsequently cut off with a diamond saw, and then the Brick in required size is left, most used in side wall.
    QX by tilt casting, shrinkage voids focus on one side, while the other side is dense. This kind of bricks are usual sabity is located towards the bottom, and of the Brick that used for sidewalls.
