Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of roll, concretely relates to a detachable and reusable composite roll. BACKGROUND

[0002] The roll is the main working component and tool for making metal produce continuous plastic deformation on the rolling mill, and the outer layer (roll sleeve or working layer) and core of the composite roll are made of different materials, and the two materials are metallurgically combined. With the popularity of composite rolls, more and more rolling mills choose to use composite rolls. The composite roll can not only meet the requirements of the rolling mill for the wear resistance, heat fatigue resistance and other properties of the roll body, but also ensure the toughness of the core and roll neck. It is an important tool for metal processing and deformation. However, the existing composite roll is usually a whole, and the roll surface of the outer layer of the roll body is easy to wear during the rolling process. Once the wear limit is reached, the entire roll is scrapped, causing resource waste and increasing production cost. When the outer layer of the roll body (roll sleeve or working layer) is damaged, the entire composite roll needs to be disassembled for replacement or maintenance, which is time-consuming and laborious and also causes resource waste, and is not convenient for reuse.

[0003] For example, Chinese patent CN220697823U discloses a detachable and reusable composite roll, which comprises a composite roll, first plug-in rods are installed at both ends of the composite roll, the first plug-in rods are respectively plugged into corresponding mounting seats, four groups of disassembly assemblies are uniformly installed around the side wall of the mounting seat, the disassembly assemblies clamp and fix the first plug-in rods, second plug-in rods are installed at both ends of the composite roll, and the second plug-in rods are plugged into the mounting seats and clamped and fixed by the disassembly assemblies.

[0004] The composite roll has the following disadvantages: although the roll can be disassembled and installed multiple times, the design of the installation calipers and clamping blocks ensures the stable clamping of the plug-in rods, and avoids the loosening or shaking of the roll during the working process, but the composite roll is designed as a whole, and the roll surface of the outer layer of the roll body is easy to wear during the rolling process. Once the wear limit is reached, the entire roll is scrapped, causing resource waste and increasing production cost. When the outer layer of the roll body (roll sleeve or working layer) is damaged, the entire composite roll needs to be disassembled for replacement or maintenance, which is time-consuming and laborious and also causes resource waste, and is not convenient for reuse.
