Embodiment 1

[0011] The invention provides a method for electrolytic phosphating of a steel wire, the steps of which are:

[0012] Step 1. Remove the oxide skin on the surface of the steel wire after heat treatment, and then rinse at room temperature. After rinsing the steel wire, perform surface activation treatment on the surface of the steel wire. Surface activation treatment refers to immersing the steel wire in a surface regulator solution with a concentration of 8%. , the immersion time is 5 seconds, the surface conditioner is emulsifier OP-10, and then more crystal nuclei are formed on the surface of the steel wire, the steps are:

[0013] Step 2. Let the activated steel wire pass through the electrolytic phosphating cell with an anode. During the passage, the steel wire cannot contact the anode. The passing speed depends on the thickness of the steel wire. The thicker the steel wire, the slower the passing speed The current passing through the anode is adjusted according to the req...

[0022] The invention provides a method for electrolytic phosphating of a steel wire, the steps of which are:

[0023] Step 1. Remove the oxide skin on the surface of the steel wire after heat treatment, then wash it at room temperature. After the steel wire is rinsed, perform surface activation treatment on the surface of the steel wire. Surface activation treatment refers to immersing the steel wire in a surface regulator solution with a concentration of 8%. , the immersion time is 5 seconds, and the surface conditioner is emulsifier OP-10;

[0024] Step 2. Let the activated steel wire pass through the electrolytic phosphating pool with an anode. During the passage, the steel wire cannot contact the anode. The passing speed depends on the thickness of the steel wire. The thicker the steel wire, the slower the passing speed , the current passing through the anode is adjusted according to the required thickness of the phosphorus layer of the steel wire and the diameter of the s...

Abstract

The invention provides an electrolytic phosphating method for steel wires, which comprises a step 1 of removing oxide skins on the surfaces of steel wires subjected to heat treatment, washing at normal temperature, and after the steel wires are washed completely, performing the surface activation treatment on the surfaces of the steel wires. The method is characterized by comprising a step 2 of passing the activated steel wires through an electrolytic phosphating tank with an anode without contacting the anode. When the electrolytic phosphating method for steel wires, which is provided by the invention, is used, the environmental pollution and energy consumption are reduced greatly compared with the conventional chemical phosphating method, and an effect which is the same as that achieved by chemical phosphating can be achieved.

Description

technical field [0001] The invention relates to a phosphating process of steel wire. Background technique [0002] In the production process of the steel wire rope, it is necessary to carry out quenching heat treatment on the steel wire, and the steel wire after quenching heat treatment has a layer of oxide skin on its surface. At present, the conventional method of removing scale is to remove the quenched steel wire through hydrochloric acid or sulfuric acid solution, then enter the washing pool and phosphating pool in turn, wash with water after phosphating, and finally saponify. Among them, phosphating usually adopts the method of chemical phosphating. Chemical phosphating will produce a large amount of phosphating slag, which will not only cause serious pollution to the environment, but also affect production efficiency and product quality, and consume high energy consumption. Contents of the invention [0003] The purpose of the present invention is to provide a pho...
