The use of thermal analysis in the production of ductile and grey iron castings

摘要

Cast-iron solidification is a complex chemical-physical process; influenced by a high number of variables that foundrymen cannot always control and adjust at will, for technical and also for cost reasons. For example, as raw materials account for almost 40% of casting costs, foundries take great care to assess the costs and benefits of each different type. Contrary to common belief, simply controlling the chemical composition of the alloy is far from sufficient because its nucieation state and various solidification phases must also be monitored.
