Abstract

The invention discloses a production method of a high-speed steel compound roller and belongs to the technical field of roller preparation. According to the production method of the high-speed steel compound roller, the compound roller comprises a roller body and roller necks which are located at the two ends of the roller body; the roller body is divided into a roller body outer layer and a roller body core portion which are made from a high-speed steel material; the roller necks are made from a nodular cast iron material; centrifugal casting is adopted for high-speed steel of the roller body outer layer; and static state casting is adopted for high-speed steel of the roller body core portion and nodular cast iron of the roller necks. By means of the method, the roller with the roller body and the roller necks made from different materials can be produced, and the thickness of the work layer of the prepared compound roller meets the using requirement.

Description

technical field

[0001] The invention relates to the technical field of roll preparation, in particular to a production method of a high-speed steel composite roll. Background technique

[0002] High-speed steel rolls are widely used and promoted in the field of steel rolling due to their high hardness, good wear resistance and excellent use effects. However, the roll is a non-standard rolling mill spare part. With the different types of rolling mills, types of rolled materials, and service orders, the dimensions, specifications, structural shapes, and pass depths of the rolls are also different. In the existing high-speed steel composite roll production technology, such as ZL97100083.2 discloses that the outer material of the roll is high-speed steel, and the core material of the roll is ductile iron. The manufacturing process is to pour the high-speed steel liquid into the rotating centrifuge mold Inside, when the high-speed molten steel in the outer layer has just solidif...
