| Abstract | Below are described results of the analysis concerning the use of two cored wire injection method (2PE- 9) and the unique application of a drum ladle as a treatment, transport and casting one, instead of a vertical treatment ladle. Parameter optimization, like: length of nodulariser wire, residual magnesium content, treatment and pouring temperature have been shown. Influence of various treatment temperatures, magnesium-cored wire velocities (Mg-treatment times) and weights of molten alloy on magnesium recovery are demonstrated. Moreover, graphite nodule content in relation to different raw materials in the charge mix are presented. Typical microstructure, mechanical properties and treatment costs are given as well. Using specific industrial conditions for tests and optimal, low scrap production of austenitic nodular cast iron (EN-GJSA-XNiSiCr35-5-2 Grade, according with EN 13835), makes this innovative method very credible. Injection of two Ø 9 mm 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 ductile iron melted in a coreless induction furnace. |
