[0002] If you want to obtain seamless pipes with smaller size and better quality, you must use cold rolling, cold drawing or a combination of the two methods. Cold rolling is usually carried out on a two-roll rolling mill, and the steel pipe is rolled in an annular hole composed of a variable-section circular hole groove and a stationary conical head. Cold drawing is usually carried out on a single-chain or double-chain cold drawing machine with a slider of 0.5~(10)0T.

[0003] During the production process of cold-drawn steel pipes, a layer of drawing lubricant is coated on the surface of the steel pipe to reduce friction during the cold deformation process. However, after cold drawing through the mold, the drawing lubricant coated on the surface of the steel pipe will partially fall off, while a considerable amount of drawing lubricant still remains on the outer surface of the cold-drawn steel pipe. When existing lubricant powder removal and recovery devices are used to process steel pipes of different sizes, the conveyor belt is often fixed in size, resulting in the conveyor belt being unable to use steel pipes of different sizes. Therefore, the utility model provides a lubricant powder removal and recovery device for cold-drawn steel pipes. Summary of the Invention
