Casting Technology

Normal Cast

Some shrinkage voids are formed under the casting scar in the annealing process.The blocks(PT)having such voids are usually installed and used in the area with no serious corrosion and the surface with scar is not used as working face,considering no influence for furnace performance and life.

Void Free Cast

Casting is performed with a large header in which most of the voids are concentrated.The header is subsequently cut off after cooling.The resultant block is compact and substantially void-free.AC-41 and AC-M are preferably in WS casting.
