Study on Defect Formation and Controlling of Centrifugal Casting High Speed Steel Roll

Number of visits: Date:2012-4-27

Centrifugal casting technology has such characteristics as simple process and easy operation to manufacture high speed steel roll.It is also easy to produce many casting defects such as segregation,crack,air hole,shrinkage and inclusion etc.,which decreases the mechanical performances and service properties.

Adopting modification process with rare earth (RE) and titanium,the microstructure and performance are obviously improved,and improving centrifugal casting parameter at the same time,the casting defects can obviously dispelled,which can increases the mechanical performance of high speed steel roll and improve the service effects.
