Abstract:
Determine the Relationship Between Solidification Time and Mechanical Properties of Heavy Section Ductile Iron Castings
Basically; it has been established within the present level of ductile iron technology that there is one complete solution to the problem of reduced properties in heavy section ductile iron castings, and one partial solution to this problem. The complete solution involves the use of gray cast iron chills within the following perimeters: 1. The use of gray iron chills on both sides of the wall of the casting equal to 33.3% of the casting thickness. 2. The use of gray iron chills equal to 40% to 50% of the casting thickness located in highly stressed areas of the casting. The location of the chills is based on casting design stress requirements.
