Embodiment Construction

[0028] The present invention will be described in further detail below by means of specific embodiments:

[0029] The reference signs in the drawings of the description include: gas explosion chamber 1, derusting chamber 2, air inlet 3, igniter 4, gas detector 5, sliding area 6, positioning block 7, elastic layer 8, abrasive material 9, inlet Material channel 10, shelf 11.

[0030] The present embodiment is a carbon steel wire processing technology, and its specific processing steps are:

[0031] (1) Select a carbon steel alloy with a hardness less than 85HRB, a weight of 200kg, and a diameter of 9mm as the raw material for carbon steel wire processing;

[0032] (2) Use a hydrogen explosion derusting device to derust carbon steel materials;

[0033] (3) Put the carbon steel material that has been derusted into a phosphate solution with a concentration of 12-20g / L and a temperature of 75-85°C for 8-10 minutes for phosphating, thereby forming a network on the surface of the ca...

Abstract

The invention relates to the technical field of carbon steel wire machining, in particular to a carbon steel wire machining process. Compared with the prior art, in the scheme, a hydrogen explosion rust removal device is adopted for removing rust of carbon steel alloy materials, hydrogen is inflated into the device, shake generated by hydrogen explosion is used for achieving mutual friction of abrasive materials and carbon steel in the device, rust removal of the carbon steel is achieved, matter generated after hydrogen explosion only contains water, and therefore direct discharging can be achieved without retreatment. In this way, the problem that a large amount of waste acid will be generated in the existing process, special equipment and method are needed for recycling, and enterprise cost generated by treating waste is increased can be solved.

Description

technical field [0001] The invention relates to the technical field of carbon steel wire processing, in particular to a carbon steel wire processing technology. Background technique [0002] Carbon steel wire is a steel wire processed from carbon steel. It has the characteristics of high strength, low relaxation, light weight and tensile strength. It is widely used in construction and industrial fields. At present, the general processing flow for producing carbon steel wire is: material selection - rust removal - phosphating and saponification - wire drawing. Among them, the rust removal process uses dilute sulfuric acid at a temperature of 55-65° and a concentration of 10-25%. The carbon steel material is placed in dilute sulfuric acid to remove the oxide layer on the surface; the phosphating process can make the surface of the carbon steel form a protective The reticular phosphating film; the saponification process can lubricate the surface of carbon steel.
