【Abstract】 Adding microelements into traditional cast iron and steel material is an effective approach to improve the performance of cast iron and steel material.The researchers from the Advanced Solidification Technology Center of Shanghai University(CAST) have been conducting a further study on the effect and mechanism of microelements including Nb,V,Ti,N,RE and so on in the cast iron and steel materials over the past two decades,and the relevant achievements have been applied in casting production.In this paper,a detail introduce to focus on the research work of the CAST in this area is given,including PQ35 brake disc gray cast iron material with Nb,microalloyed lining for large semi-self-grinding ball mill,high chromium iron/ductile iron centrifugal casting bimetallic composite roller cycle,bainite cast iron/ductile cast iron composite bimetallic composite roller.更多还原
