Investigations on the Crack of Centrifugal Casting High-Speed Steel Rolls

Abstract:

Article Preview

A study on solidification process of centrifugal cast high-speed steel (HSS) rolls and the crack forming condition is discussed. The result was represented that the crack forming was because of the solidification layer strength of HSS roll was low, and a clearance between the solidification layer and the mould, and the solidification layer of HSS roll could not endure a large centrifugal pressure. In common centrifugal casting, the free solidification constriction of HSS rolls was difficult, which accelerated the crack propagation. The appearance of mesosphere and axial solidification was unfavorable to obtaining the compact roll structures, which accelerated HSS rolls to crack.
