Exploration and Practice of High Strength Track Cast Steel Materials
In order to meet the increasing needs of large-scale and heavy load development of construction machinery and equipment,based on the existing E-grade steel,the composition and content of alloying elements are reasonably adjusted according to the characteristics of E-grade steel of China Railway Corporation.The liquid steel adopts rare earth microalloying technology,and uses the unique physical and chemical properties of rare earth elements as well as purification,metamorphism and alloying effects to develop high-strength track cast steel materials with excellent performance,and has been successfully applied to product castings and loading operation.
