Duration: 2014-2017

Project ID: INNOTECH


The main goal of the project was to develop an innovative and ecological process of metallurgical cast iron processing including operations: desulfurization, spheroidization or vermicularyization and its modification, in a reactor placed in a casting mold, in order to produce high quality castings. As a result of the research carried out, a new method was developed and refinement of cast iron, involving the use of the reactor, in the casting mold. The reactor can be used to refine the cast iron output in an electric or cupola furnace. In the case when cast iron is used in the electric process, as a result of using a reaction chamber (reactor), there is no problem with obtaining high quality castings with spheroidal or vermicular graphite, with the required properties.
The positive result of the work carried out allowed to master the method of making reactors, and then to launch the experimental work station, at the PEDMO Tychy plant. Two pilot foundries, ie KAW-MET, Orłów near Przemyśl and Odlewnia „DRAWSKI” S.A. also participated in the development works under the project as project consortium members. The use of the new method in foundries will allow to reduce the emission of a large amount of harmful gases released into the atmosphere as a result of unproductive oxidation of magnesium with oxygen from the air, as well as to eliminate the light effects caused by magnesium oxidation.
