Usually, we make this type of roll by static cast and centrifugal cast. We recommend using centrifugal cast rolls for better performance when the groove in the roll body is not too deep. With more alloy added in, we can get a microstructure consisting of spheroidal graphite, pearlite and primary carbide type M3C up to 30%. Meanwhile, the core of the roll still keeps very strong with a great amount of spheroidal graphite in the matrix of ferrite. When the groove in the roll body is very deep, we recommend using rolls static cast with groove to achieve a low hardness drop between the body surface and bottom of the groove.Machining EquipmentQuality ControlPackingand DeliveryIf you are interested in our mill rolls,pls send the detail drawing and technical requirements to us,we will send you prompt reply,professional service and best quotation.
