Late graphitizing modification with vch cast inserts in chilling-prone castings

The technology of graphitizing modification of graphitized cast iron, using cast inserts for melt processing, which is the most optimal according to the technical-and-economic criterion, is discussed. Cast inserts are an effective modifier for the late graphitizing processing of medium- and large-sized castings. The analysis of the obtained results shows that the use of a ferrosilicon cast insert with a complex of modifier-elements for the graphitizing modification occupies an intermediate position in its effectiveness between jet modification (MSI-process) and bucket modification, taking into account general quantitative ranges of their consumption.
