Description

Technical Field

[0001] The utility model belongs to the field of metallurgical roller production, in particular to a water quenching machine for roller production. Background Art

[0002] Metallurgical rollers are tools that cause metals to undergo plastic deformation. They play a vital role in the processes of steel, aluminum, and copper rolling, and are important consumable parts that determine the efficiency of rolling mills and the quality of rolled materials. They are mainly used to suppress and change the shape and size of metal materials, and can process conventional metal materials as well as special materials, such as high-temperature alloys and cemented carbides. Rollers are mainly composed of a roller body, a roller neck, and a shaft head. The roller body is the middle part of the roller that actually participates in rolling metal. The roller neck is installed in the bearing, and the rolling force is transmitted to the frame through the bearing seat and the pressing device. The shaft head at the transmission end is connected to the gear seat through a connecting shaft, and the rotational torque of the motor is transmitted to the roller. The rollers can be arranged in the form of two rollers, three rollers, four rollers, or multiple rollers in the rolling mill frame. At present, rollers need to undergo multiple processes in the production process, among which quenching is an important process that directly affects the strength and toughness of the rollers. When cold quenching the rollers, the mill needs to be water quenched by a water quenching machine.
