Centrifugal casting - 進出口

The cast iron roll is produced by a horizontal centrifugal casting process with high-speed steel as the work layer and nodular iron as the core. The material of centrifugal casting iron roll contains plenty of alloying elements such as Mo, Ni, Cr, etc. The high hardened eutectic carbides & second carbides, evenly distributed in tempered martensitic matrix, make the wear and thermal cracking resistance very excellent. Besides, the resistance to surface roughing is also good. In a condition of hot rolling, the contact points between steel strip and the work rolls can form a thin adherent oxide film on the roll surface, which plays a good role in the wear features and the quality of the strip surface. The main application is as a working roll for hot-rolled strip leveling rack and rack of high-speed wire mill.

HSS Roll High speed steel roll known as HSS roll are a kind of hot roll material with excellent performance. The application of high speed steel roll is an important component of the development of modern steel rolling production and another major technological change in the development of the steel industry. High speed steel rollers have higher hardness and wear resistance than traditional rollers. The centrifugal casting high-speed steel rollers have been widely used in the production of hot-rolled narrow strip steel, sheet steel, section steel, rebar, spring flat steel, high-speed wire and other fields. They are not only used for working rolls, but also for the back-up rolls.
