ROLLER STEEL WITH HIGH CHRONIUM AND ROLLER

The invention is used to cast compound roller by centrifuging. The steel contains Mo, W, Ni, Co, Nb, V and Ti besides high-carbon and high chromium, which makes the steel have the proporty of high hardenability and temper-resisting. The principal type of carbures in steel is M7C3. It presents island...

Zusammenfassung:	The invention is used to cast compound roller by centrifuging. The steel contains Mo, W, Ni, Co, Nb, V and Ti besides high-carbon and high chromium, which makes the steel have the proporty of high hardenability and temper-resisting. The principal type of carbures in steel is M7C3. It presents island distribution. The roller is provided with higher hardness, better tenacity and high temp. hardness. It is easy to grind and has a even cloudburst surface. In making procedure, two components are casted in three times. The cost is decreased.
