AZS Bricks Using Precautions in Glass Kiln

1.Irregular Changes in Thermal Expansion

The expansion curve of the AZS brick has an anomaly near 1000 °C, and the internal ZrO2 crystal undergoes a reversible crystal transformation with a large volume change. Therefore, the product containing ZrO2 should not be used at around 1000 °C, the temperature is often A region that fluctuates sharply. When baking the kiln, the temperature change at 900~1150 °C should not be too large, generally can not exceed 15 °C / h, requiring a steady temperature rise. Some AZS refractory parts should be protected from blowing cold air and protected by other bricks to prevent cracking.

2.Shrinkage

When casting, there are often shrinkage holes in the casting mouth, the brick body has more pores and poor density. Therefore, when the glass wall of the glass melting part is made, the shrinkage holes are directed toward the direction of the kiln. When AZS brick is eroded to a very thin level, AZS refractory bricks will cause a leakage of glass liquid. When used in the upper flame space of the kiln, the service life is very long, there is no problem of running glass. Therefore, the casting port is used outwards to extend the service life.

3.Eutectic  

The AZS firebrick and the clay brick are in contact with the clay brick. The eutectic phenomenon occurs at a high temperature of 1300 °C. Therefore, when the refractory material is selected, the two refractory materials with severe eutectic phenomena should be avoided from contact with the masonry, such as silica brick casting. Below the zirconium corundum brick,AZS brick is most susceptible to erosion by the cast zirconia corundum brick.

AZS Bricks Packing & Delivery

Consider various and complex transportation conditions, fused cast azs products are packing following the highest standards with foam boards between every two AZS blocks, AZS refractory bricks corners protected with triangular hard card boards and multi-strengthened by steel bands and wrapping in plastic film on the outside.

For easy location of different materials,packing lists are places both inside and outside packages, and shipping marks are clearly painted on all cases.

AZS Bricks

AZS Bricks for Glass Furnace corrosion resistance increases with the increase of ZrO2 content. Because ZrO2 has a melting temperature of up to about 2700, AZS brick has a high resistance to acids, alkalis glass liquids. Due to the above advantages of AZS refractory bricks, fused cast azs bricks are used not only for high temperature, severe corrosion, but also azs bricks used for contact with molten glass, AZS refractory bricks are widely used in the upper structure of glass melting furnaces.

Carbon Brick Advantage

1.Refractory Carbon Brick to Achieve Microporous or Ultramicroporous

molten iron mainly penetrates into the interior of the carbon brick along the large-aperture holes and cracks of the refractory carbon brick.

Therefore, carbon refractory brick realizes micropores or ultramicropores, reduces pores with a pore diameter larger than 1 μm, which prevents the molten iron from infiltrating into the carbon fire brick.Thereby slowing the erosion of carbon bricks by molten iron.

2.Carbon Brick to Achieve Stomatal Closure

The main channel for the penetration of molten iron into the interior of carbon refractory bricks is the pores of carbon bricks.

3.Improve Thermal Conductivity of Refractory Carbon Bricks

Increasing the thermal conductivity of carbon bricks is an effective measure to improve the cooling effect of carbon bricks, reduce the temperature of carbon bricks, and slow down the erosion rate of carbon bricks.

4.Improve Resistance of Working Layer Carbon Bricks to Anti Iron Water Erosion
