Effect of Solution Factor and Gate Distance From Reaction Chamber on Production of Ductile Iron by In- mold Process

This study is purposed for optimization of solution factor and gate distance from reaction chamber on production ductile iron during in-mold process, to achieve maximum spheroidizing of graphite in ductile iron. The results of metallographic studies show that efficiency of reaction chamber depends on its solution factor (or dimensions of the chamber). Solution factor of 0.015-0.02 provides optimum spheroidizing in ductile iron specimens, and in this condition gate distance (from the reaction chamber) up to 15cm show no significant effect on spheroidizing of graphite, however, gate distance of 10 cm provides more spheroidized graphite and better distribution of graphite.
