Wire rod rust removal process

Abstract

The invention belongs to the technical field of wire surface treatment, particularly relates to a wire rod rust removal process, and rust stains on the surface of a wire rod can be removed by utilizing a multi-specification wire rod rust removal device. A third rotating shaft of the multi-specification wire rod rust removal device is internally provided with a cavity with the concentration of 20%-25% of hydrochloric acid, a liquid spraying channel with the diameter of 50 microns to 100 microns is arranged in bristles of a first brush, and the liquid spraying channel is in communication with acavity inside the third rotating shaft; a water storage bag for storing water is arranged in the channel below a mounting frame of the multi-specification wire rod rust removal device, the liquid storage bag is provided with a plurality of stepped holes with different diameters allowing wire rods to penetrate through, the diameter of the upper half section of each stepped hole is smaller than thediameter of the lower half section, a plurality of through holes with 50 microns to 100 microns are uniformly arranged on the inner wall of the upper half section of the step holes in the circumferential direction, and semi-spherical bulges are uniformly arranged on the inner wall of the lower half section of the step holes in the circumferential direction. A dryer is arranged below the multi-specification wire rod rust removal device, the dryer is used for drying the processed wire rod, and a winding machine is arranged beside the dryer for rolling the wire rod.

Description

technical field [0001] The invention belongs to the technical field of wire rod surface treatment, in particular to a wire rod derusting process. Background technique [0002] In the steel wire drawing production in the metal products industry, in order to ensure the quality of the steel wire product and improve the service life of the drawing die, it is necessary to derust the raw material used for steel wire production, that is, the hot-rolled wire rod, so that the wire rod after drawing The quality of the obtained steel wire will not be affected. However, the existing rust removal process for wire rods is slow in removing rust on the surface of wire rods, and the rust removal efficiency is low. At the same time, it cannot ensure that the rust on the surface of wire rods is completely removed, and it is impossible to remove rust on large quantities of wire rods. How to improve The speed of removing rust on the surface of wire rods and improving the effect of removing rust...
