Austempered Ductile Iron (ADI) is obtained by exactly controlled heat treatment process of nodular cast iron. Ductile iron samples are first austenitised to dissolve carbon, then quenched rapidly to the austempering temperature to avoid the formation of deleterious pearlite or martensite. Resulting ausferrite microstructure consists of acicular fer...

This paper examines the impact of improving working conditions and increasing capacity with Dual track system. Three different cases were examined: Power ratio 100-650 kW, 200-550 kW and 300-350 kW. All three different cases were obtained in very similar conditions (time necessary for chemical analysis, alloying processes, slag cleaning e...
