Crosimax – an innovative alloy of silicon with chromium, iron, aluminium and calcium, as a versatile and effective reducing agent of increased deoxidising potential towards Cr2O3 – to be applied in manufacturing of low and ultra-low carbon grades of ferro-chromium (POIR.01.01.01-00-0161/21)

STAGE 1 INDUSTRIAL RESEARCH

1. Akademia Górniczo – Hutnicza in Cracow, a subcontractor (hereinafter: AGH), to conduct a series of calculations and model simulations with the use of thermochemical bases and to perform theoretical analyses in order to compare physico-chemical properties of the Crosimax alloy and the base alloy – LC FeSiCr – produced by the Applicant with the use of measurement data from the current production of the alloy manufactured so far.
2. AGH to manufacture three batches of the Crosimax alloys on a laboratory scale by melting the Applicant’s product – LC FeSiCr – with other reagents e.g. calcium silicon, silicon of technical grade and aluminium, in order to obtain samples of the Crosimax alloy of three different chemical compositions intended for laboratory tests of the scope specified in paragraphs 3 and 4 below.
3. AGH to conduct a series of laboratory tests for the purpose of comparison including analyses of chemical composition, morphological phase composition and physical properties such as density, melting point or enthalpy of fusion of the obtained samples of the Crosimax alloys and the base alloy – FeSiCr – manufactured in the industrial environment of the Applicant.
4. AGH to conduct laboratory-scale comparative melts of LC FeCr with the use of FeSiCr and the new group of the Crosimax alloys as a reducing agents in order to confirm their higher reducing power.
5. The completion of the task will result in identification of three compositions of the Crosimax alloys for manufacturing tests on industrial scale on the Applicant’s existing production line.
