ANALYSIS OF THE POURING AND SOLIDIFICATION PROCESS OF ALLOYED STEEL CASTINGS FOR LOW - TEMPERATURE PERFORMANCE

The study forms a part of the program of applied industrial research executed under Target Project No. ROW-II-403/2008 at MAGNUS-NORD Sp z o.o in Toruń. Pouring and solidification of two large steel castings weighing 200 kg (casting I) and 700 kg (casting II) was simulated, basing on the casting manufacturing technology used up to now. Detailed analysis of the results of simulation resulted in changes proposed and introduced to the so far used manufacturing technology. After the said changes had been introduced, the simulation of the casting process was done once again. The analysis of the obtained results indicated a substantial improvement in the solidification conditions and effectively eliminated the porosities and shrinkage cavities.
