【Abstract】 The effect of ferro-silico-barium and its rare earth complex alloy on mechanical properties, castability and metallographic structure of cast iron containing Pb、As and Sn have been studied. Through analysis and comparison it has been proved that inoculation with 0.10% mixed alloy made up of ferro-silico-barium and ferro-silico-rare earth may improve effectivly the usability of Longyan pig iron.更多还原
