Casting speed directly determines the casting time, and every fused cast azs block has its own best casting time. Unreasonable casting time can cause many defects in the casting.

High casting speed

With the rapid development of furnace industry, in recent years, tank bottom of glass furnace in some glass factory is often reported to have leakage event. The main reasons of leakage is that the bottom structure of the pool is not effective to prevent the drilling of glass liquid or caused by metal particles which drill down and cause erosion. So tank bottom which can prevent glass liquid from drilling up and metal particles from drilling down is required.

Casting technology is a method to manufacture fused cast azs block, and there are several steps of casting, however, it has a close relationship with the

casting temperature which can determine the quality of fused cast azs block.

Casting temperature is the stream temperature which is near the furnace at the mouth and is measured by optical pyrometer. When fused cast azs block is

melting, the casting temperature can reach to 1820-1840℃. The viscosity of molten liquid depends on the chemical composition and temperature of the

Why does zircon brick have dense structure?

If you expect the glass furnace to reach the designed service life, you need to know both the appearance quality and inner quality completely of refractory bricks such as fused cast azs block, not only the good properties, but also the weakness, for instance, which parts can have flaws, which parts must be perfect.

Advantages
Zircon brick is a refractory product made of natural zircon. It has the advantages of strong slag resistance, high mechanical strength, high refractoriness under load, large abrasive resistance and excellent thermal shock stability; it is an important material for furnace construction in the glass industry.

Applications:

Refractoriness is different from melting point, melting point is the balance temperature that materials reach to melting point which is between solid and liquid crystal, however, refractoriness is a process in which the solid phase of the material is gradually dissolved in the liquid phase and finally is melted with the increasing temperature.

Formation of shrinkage cavity: In the mold, the molten liquid occurs when the self - shaped wall begins to solidify. If the molten liquid reduces caused by the liquid shrinkage and solid shrinkage and don't get added, which will form concentrated shrinkage cavity in the place of final solidification of fused cast azs block.

Zircon Brick
zircon brick is made of stable and high pure zircon sand in which the zircon content is over 64 % , so zircon is as the main crystal phase ,it is an important firebrick in Zircon related refractory bricks. It has the advantages of high mechanical strength, high refractoriness under load, excellent thermal shock stability, good creep resistance and good corrosion resistance to glass liquid.
