Abstract

The process comprises producing a molten mass of cast iron in a vessel, transferring the molten mass to a casting mold, and introducing a pearlite stabilizing agent into the molten mass while it is being transferred from the vessel to the casting mold. Preferably, the pearlite stabilizing agent is introduced into the pouring stream of the molten cast iron. Tin (Sn) and antimony (Sb) are proposed as pearlite stabilizing agents, which may take various physical forms and might be accompanied by an inoculant.
