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.

When the casting edge temperature drops to below the solidus temperature, the casting surface will form a layer of crust which is a sealed container in solution. When further cooling, liquid in shell forms liquid shrinkage due to the reducing temperature, on the other hand, solid shrinkage is formed due to the thickening of the crust. The two shrinkages make the liquid level reduce due to lack of supplement. In addition, solid shell occurs solid shrinkage due to reducing temperature which makes the appearance size of fused cast azs reduce. As the liquid shrinkage and solid shrinkage of AZS liquid are significantly more than the shell of solid shrinkage, the page will be separated from the top of the shell, and the shrinkage cavity appears under gravity. With the solidification is in proceed, the crust is becoming thick and the liquid level is reducing, after all the liquid solidified, shrinkage cavity is formed in the core part of fused cast azs block.

Factors that affect the size of the shrinkage cavity: The molten liquid of itself shrinks large, and then the shrinkage cavity volume is large; The molten liquid of itself has large solid shrinkage, and the shrinkage cavity volume is large; molten liquid of itself shrinks big, and the shrinkage cavity volume is small; the slower the casting speed, the smaller the shrinkage cavity volume.
