A process for determining the amount of structure modifying agent for addition to a cast iron bath to obtain a piece of compacted graphite cast iron (cgi) or optionally spheroidal graphite cast iron (sgi).

摘要

By studying heat transfer in a sample vessel containing a sample of molten cast iron, it is possible to carry out accurate predictions of the microstructure in which the molten cast iron sample will solidify. This method is also highly suitable for automatisation by using a computer.
