A study of segregation mechanism in centrifugal cast high speed steel rolls
As illustrated in Fig. 4, a schematic diagram shows where the different samples are retrieved from the roll.The effect of radial location on the hardness, red hardness, tensile strength, elongation percentage, impact toughness and weight loss of centrifugal cast HSS roll are shown in Fig. 5, Fig. 6, Fig. 7.Among them, the hardness The single groove steel rolling amount of high-boron high speed steel rolls increases by 500% than that of bainite cast iron roll, when the rolls are used in K1 mill housing of bar mill.

Influence of Rotation Speed and Filling Time on
Horizontal centrifugal casting is commonly employed in the production of symmetrical cylindrical parts10,11 and functionally gradient materials.12 Without a core, hori-zontal centrifugal casting process can present a cylindrical inner hole. And the casting process is a quite easy process. There are still many technological challenges to overcome,1.. IntroductionCentrifugal casting is a widely used technique in fabricating metal rolls and has the advantages of low energy consumption, small pollution, simplicity and high efficiency [1], [2], [3], [4].It is also used in the manufacture of high-speed steel (HSS) rolls which have high hardness, excellent red hardness, hardenability and A study on the crack control of a high-speed steel roll

What is Centrifugal Casting and How Does It Work? MetalTek
Centrifugal casting is a process that delivers components of high material soundness. As a result, it is the technology of choice for applications like jet engine compressor cases, hydro wear rings, many military products, and other high-reliability applications. It has also proven to be a cost-effective means of providing complex shapes Figure 1. Manufacture by centrifugal casting: (a) casting of outer working layer; (b) casting of the core intended to achieve an optimal bond with the outer working layer; (c) casting of the remainder of the core and roll necks by gravity and static solidification.

Centrifugal casting of bi-metal rolls Google Patents
A method for centrifugally casting bi-metal or composite iron and steel rolling mill rolls. The shell of the roll is centrifugally cast by rotating a mold with its major axis arranged vertically, in which, immediately before the shell metal is completely solidified, the rotation of the mold is greatly reduced or stopped and unsolidified shell metal is drained.J.
