Embodiment 1
[0032] Such as figure 1 with figure 2 As shown, for the pickling of the steel strand 3, the present invention provides a prestressed steel strand aeration pickling tank, comprising a pickling tank 1, an aeration pipe 2 and a compressed air pump, the aeration The tube 2 is arranged around the inner wall of the pickling tank 1 in a circle, and the surrounding area is set evenly, with an upper and lower distance of 100 mm. All under pressure, ensure that steel strand 3 is all cleaned up and down. Under the preferred solution, the pickling tank 1 is provided with a hydrochloric acid tank, and the hydrochloric acid tank is provided with a lye spray neutralization device to prevent pollution caused by a large amount of volatilization of hydrochloric acid when the temperature is too high.
[0033] One end of the aeration pipe 2 is connected to an external compressed air pump, and the compressed air pump generates an air pressure of 0.6Mpa. The air pressure of 0.6Mpa can make the p...

Abstract
The invention discloses a prestressed steel strand aeration pickling tank and a pickling method, belonging to the field of steel strand manufacture. A prestressed steel strand aerated pickling tank, comprising a pickling tank (1), an aeration pipe (2) and a compressed air pump, the aeration pipe (2) is spirally arranged in the pickling tank (1) Around the inner wall, one end of the aeration pipe (2) is connected to an external compressed air pump, and the other end is closed, and the aeration pipe (2) is uniformly provided with aeration holes (4) facing the inner side of the pool. The pickling method of the aerated pickling tank goes through the steps of adding acid, ventilating, removing the oxide layer, washing, phosphating and boronizing to pickle the steel strand (3). It can achieve the goals of clean and sufficient cleaning of steel strands, and easy transportation. The required pickling pool is small, the pickling efficiency is high, and the consumption of acid solution is small.
Description
technical field [0001] The invention relates to the field of steel strand manufacturing, in particular to an aeration pickling tank and pickling method for prestressed steel strands. Background technique [0002] The raw wire used in the prestressed steel strand industry needs to be heated for rolling, and there will be a layer of iron chloride on the surface at the end, so the surface of the iron chloride must be washed off with hydrochloric acid or sulfuric acid before drawing. The wire reacts in the pickling tank, one depends on the concentration, the other depends on the time, and the third depends on the full contact with the surface of the acid solution. Now the wire rods arriving at the factory are fully bundled by the manufacturer with steel wires, which is convenient for the next step of transportation. If the wire rods are unbundled before pickling and the wire rods are loose, the volume is very large, and the acid pool has to be built very large. The transportati...
