Product Description High Speed Steel Rolls (HSS)Product DescriptionHSS rolls are made such that highly alloyed Tool Steel/HSS material is metallurgically bonded onto a forged steel or nodular iron shaft.In HSS rolls by CPC process, highly alloyed shell metal continuously poured into the mould to create a clad onto the forged steel shaft. The process is called as CPC. The result is a very hard working layer on the forged roll neck (shaft).Considerable amount of carbides in the microstructure make these rolls ideal wherever the very high wear resistance is needed.In HSS rolls by CC (Centrifugal Casting) process, high alloyed and wear resistant shell material is centrifugally cast and then soft core material is poured into the precast shell. Advantages of HSS Rolls ;? Highly wear resistant shell material durable at high temperature provides high pass performance and good surface finish.? No segregation or shrink cavities due to the special casting process. Solid and fine microstructure.? Required hardness depth is exactly provided due to the manufacturing process.HSS rolls are designed and produced as per end user's requirement considering product rolled, max/min roll dia and other working conditions.HSS rolls are getting more and more popular in today's high capacity modern mills. These rolls are ideal in bar, wire&rod mills, light section and narrow to wide strip mills at finishing stands.
