Problems solved by technology

The pickling process not only causes a lot of waste of resources, but also has poor working environment, high labor intensity and extremely unsafe conditions.
especially serious pollution to the environment
In order to solve this common phenomenon, recently developed countries and domestic large-scale production enterprises with certain strength have adopted high-speed shot blasting, sand blasting, and grinding processes and equipment to clean the surface of bar blanks. The cost of the process is high, the cost is huge, and it is accompanied by a lot of noise and dust pollution, and the cleaning of the surface of the material is not thorough, so it has not been widely used, and only a small number of manufacturers use it.
At present, there is no purification and cleaning technology that can effectively purify and clean the oxide layer on the surface of bars, strips, pipes, and billets without the above-mentioned pollution, is economical, practical, and suitable for various geometric cross-section steels.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] The present invention metal bar, metal pipe rust removal device such as figure 1 As shown, it includes an organic base 1, a reduction box 2 is installed on the upper side of the base, and a motor that drives the reducer to rotate. A clamping bar or other geometric type is installed on the output shaft of the reducer near the center of the base. The rotatable chuck 3 of shape material, the other side of support is equipped with slide shaft 4, non-rotating chuck 5, spring 6.

[0020] The working principle of the metal rod and metal pipe rust removal device of the present invention is: a metal material to be twisted and rust removed, when the reducer rotates, the clamped metal material is twisted accordingly, and after the twisted to the rated number of turns, reverse twist To the corresponding number of turns, the internal structure of the metal s...

Abstract

A method for removing rust (oxidized layer) from the metallic material (rod, strip, tube, etc) includes such steps as controlled radial twisting and controlled reverse twisting. Its advantages are no environmental pollution and no noise. Its apparatus is also disclosed.

Description

technical field [0001] The invention belongs to a metal material derusting method and device for cleaning and derusting the surface of metal rods, strips, pipes, blanks or other geometric cross-sections before drawing or finishing rolling. Background technique [0002] At present, manufacturers and scientific research institutions in steel reforming, fasteners, metal products and other industries still use sulfuric acid, hydrochloric acid, nitric acid, oxalic acid, phosphoric acid, and hydrogen for surface purification and cleaning before steel cold drawing or finishing rolling and flaw detection. Fluoric acid or mixed acid is used for surface purification, water washing, and neutralization, and then a lubricating layer is applied, and then drawing or rolling is carried out. The pickling process not only causes a lot of waste of resources, but also has poor working conditions, high labor intensity and is extremely unsafe. Especially serious pollution...
