Problems solved by technology
[0003] The structure of traditional pickling equipment cannot fully pickle the wire, and the washing speed is slow and the washing is not in place. Sometimes it is difficult to completely remove the oxide film on the metal surface. In addition, a large amount of waste liquid generated during the pickling process is easy to cause pollution. If Need to deal with the need to connect additional equipment, resulting in low continuity of the production process
In addition, some existing pickling processes still have certain defects in the implementation process, such as complex process steps, long cycle and high cost, poor pickling and cleaning effects, incomplete removal of oxide film, or excessive acid The problem of washing and destroying the internal structure of the wire is difficult to meet the needs of efficient production

Embodiment Construction
[0018] refer to figure 1 , a kind of wire pickling process of the present invention, comprises the following steps successively:
[0019] a) Feeding: feed the required pickled wire into the pickling tank by the feeder, and adjust the feed of the pickling liquid in the pickling tank to a suitable speed;
[0020] b) Preheating and heating: use steam to preheat and heat the pickling tank that has been fed until the temperature of the pickling tank rises to 50°C to 70°C;
[0021] c) pickling: immerse the wire rod in the pickling tank, which is equipped with a normal temperature, 20% to 30% hydrochloric acid solution;
[0022] d) Cleaning: Send the wire from the pickling tank into the clear water washing tank for soaking, and wash off the acid solution on the surface, wherein the clear water washing tank is filled with clean water;
[0023] e) High-pressure water washing: send the wire from the water washing tank into the washing tank and wash it with high-pressure water, and kee...

The invention discloses a wire pickling process. The wire pickling process includes following steps: a), feeding; b), preheating to increase temperature; c), pickling; d), washing; e), using high-pressure water to flush; f), drying; g), coating the surface of a wire. The process is simple in step and capable of effectively lowering cost and properly shortening period; the wire is subjected to a process sequence of pickling, washing and flushing with high-pressure clear water, so that oxidation film removing effect is good, or the problem that excessive pickling causes damage to inside structure of the wire is avoided, and needs on efficient production are difficult to meet. Pickling equipment is adopted, and a plurality of hairbrush rollers are arranged inside a pickling tank and efficiently rotates under control of a motor to brush and remove oxide on the surface of the wire, so that cleaning effect can be enhanced; a recycling tank is arranged below the pickling tank, and acid liquidenters the recycling tank through a recycling pipe and is recycled by a circulating pump after being chemical treated and physically filtered, so that energy conservation and environment protection are realized.
Description
【Technical field】 [0001] The invention relates to the technical field of pickling technology, in particular to the technical field of wire pickling technology. 【Background technique】 [0002] When the factory produces mechanical products such as bolts and screws, the production process mainly includes steps such as wire annealing, pickling, drawing, forming, etc. The purpose of pickling is to remove the oxide film on the surface of the wire and form a protective layer on the metal surface. Film, in order to reduce the scratches caused by the wire rod to the tool and mold during the subsequent drawing, cold pier or forming process. [0003] The structure of traditional pickling equipment cannot fully pickle the wire, and the washing speed is slow and the washing is not in place. Sometimes it is difficult to completely remove the oxide film on the metal surface. In addition, a large amount of waste liquid generated during the pickling process is easy to cause pollution. If Ne...
