Solving method of casting shrinkage defects, the most fundamental starting point is the "thermal equilibrium." The methods are: (1) at the thickest section of the machine tool castings and thermal structure formation, the implementation of rapid solidification, artificially basic balance throughout the machine casting temperature field. Inside and outside the cold iron, the local use of heat storage capacity of zircon sand bollard, chromite sand or special coatings.
