Problems solved by technology
The disadvantages of the existing process technology are: 1. When the steel wire is continuously drawn twice, because the thickness of the boron layer on the surface of the steel wire is low, the lubricating effect decreases during drawing, and the normal speed of drawing cannot be guaranteed; 2. The fine specification 1.15 When the mm steel wire is drawn, the boron-coated layer is destroyed in advance, the surface quality of the steel wire is not good, and the finished steel wire shines after drawing, which affects the bonding performance of the final steel cord and rubber; 3. The subsequent steel wire drawing speed is limited, and production low efficiency

Embodiment Construction
[0015] The following is a further detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings.
[0016] see figure 2 , a steel cord wire rod surface treatment production process, comprising the following steps: 1. setting off wires, 2. mechanical rust removal, 3. high-pressure water washing, 4. hydrochloric acid washing, 5. cold and hot water washing, 6. boron coating, 7. cold air drying, the In the ⑦ drying step, use a drying and purging device to purge the wire rod, and the purge pressure is 0.15Mpa. The pressure is 0.05 Mpa-0.30Mpa, and then enters the wire drawing.
[0017] On the basis of the original boron coating process, a boron coating treatment process is added. The purpose is to quickly and evenly coat a layer of borax protective film on the surface of the steel wire, and to maintain a certain thickness of the borax coating when the steel wire is drawn at high speed. It is more conducive to the improvement o...

The invention discloses a surface treatment production technique for steel wire rods of steel cords. The surface treatment production technique comprises the following steps of (1) paying-off; (2) mechanical derusting; (3) washing; (4) acid pickling; (5) cold and hot water washing; (6) boron coating; (7) drying; (8) secondary boron coating; and (9) secondary drying and then drawing of steel wires. The production technique is capable of increasing the speed of the steel wire drawing, improving the production efficiency, improving the adhesion property of the steel cords and rubber, and particularly improving the combining capacity of a boron-coating layer and the steel wires, so that thin specification steel wires are capable of being subjected to secondary continuous drawing easily, and the surface quality of the steel wires can be improved at the same time.
Description
technical field [0001] The invention relates to the field of steel cord processing, in particular to a surface treatment process for wire rods when producing steel cords. Background technique [0002] The production of steel cord must go through the process of pretreatment and drawing. The quality of the steel wire drawn in this process is directly related to the production of the subsequent process and the influence on the bonding performance of the steel cord. The 5.5mm wire rod of the steel wire needs to be coated with boron before drawing. The borax has a certain binding ability with the surface of the steel wire, so that it will not be damaged after entering the drawing; it also has a certain ability to absorb lubricant powder, thereby improving the lubrication of the steel wire drawing. Effect. When the pretreated rough drawing steel wire is drawn at high speed, there is no high-quality lubricating carrier, and it is impossible to carry out the second continuous drawi...
