FIELD: machine building.
SUBSTANCE: group of inventions relates to compound rolls for a rolling mill. Said compound roll contains a sintered inner core of a first cemented carbide and at least one sintered outer sleeve of a second cemented carbide located around the inner core. Said outer sleeve and inner core are assembled together and have joining surfaces and a bounding interface at the point of contact. Said inner core and at least one outer sleeve are fused together by heating without applying external pressure, ensuring thermal expansion between the inner core and said at least one sleeve when at least the inner core and at least one outer sleeve are exposed to vacuum or a gas atmosphere.
EFFECT: compound roll is obtained without need for application of external pressure.
