摘要: A compound roll includes a sintered inner core of a first cemented carbide and at least one sintered outer sleeve of a second cemented carbide disposed around the inner core. The outer sleeve and inner core each have a joining surface, wherein when the inner core and outer sleeve are assembled each joining surface contact to form a bonding interface therebetween. When the assembled, sintered inner core and outer sleeve are heated to a predetermined temperature the sintered inner core and outer sleeve are fused together at the bonding interface to form the unitary compound roll. To reduce the overall cost of the compound roll, a lower cost cemented carbide, or a cemented carbide with a lower density can be used for the inner core and fused to an outer sleeve of a virgin cemented carbide, thereby reducing the powder cost and/or reducing the overall mass of the compound roll.
