Manufacturing of Ferritic Low-Silicon and Molybdenum Ductile Cast Iron with the Innovative 2PE- 9 Technique

Open access


The use of two cored wire injection methods (2PE- 9) and the unique application of a drum ladle as a treatment, transport and casting one, instead of a vertical treatment ladle are presented. Optimization parameters, like: length of nodulariser wire, treatment and pouring temperature have been shown. The influence of various treatment temperatures on magnesium recovery is demonstrated. The typical microstructure, mechanical properties and cost calculation of the ferritic ductile cast iron (type SiMo - EN-GJS-SiMo40-6 Grade) production according to EN 16124:2011 (E) are presented. Injection of two Ø 9 mm as well wires; cored in FeSi + Mg nodulariser mixture and inoculant master alloy into a drum ladle is a treatment method that can be used for the production of ferritic ductile cast iron (SiMo) melted in a coreless induction furnace.
