Centrifugal and Static Casting Sphereroidal GraphiteCast lron Roll

Properties: Thanks to its higher content of Ni and Mo alloys, pearlite, bainite and martensite matrix with excellent performance are produced. The roll has the higher conductivity of thermal and high tensile strength due to the graphite of graphite form. A dense net primary cementite with high wear-resistance is produced through changing the heat treatment technology and the composition of the structure with bainite, martensite and aciculan nodular.

Applications: Roughing and intermediate stands of various continuous rolling mil,finishing stands of bar mil,section mil,fnishing stands and back up rolls of strip mils,also suitable for stainless-steel strip hot mills.
