Description

[Detailed description of the invention] The present invention relates to a continuous pickling treatment device for shaped steel, which efficiently pickles, washes, and dries a large number of shaped steel at once, and reduces cleaning costs by greatly improving processing capacity. The purpose is to achieve this goal.

Hereinafter, the embodiment will be described with reference to the drawings. First, in the drawings, 1 is a conveying roller, 2 is an angle steel, 3 is a channel steel, and 4 is an H-beam steel.

Then, the spray liquid (e.g. acid solution or submerged water) sprayed onto these shaped steel materials is transferred to the wall surface of the shaped steel materials and flows down one after another.
That is, it is placed on the conveying roller 1 so as to be returned to the washing tub (or tank).

An acid spray zone 5, a submerged spray zone 6, and a dry spray zone 7 are sequentially provided along the conveyance path.
Between the conveyance rollers 1, 1, . . . in each zone, a pipe 8 for top spray and a pipe 8' for bottom spray are arranged above and below the conveyance path so that their nozzles face each other. Vertical spraying consists of a device, and horizontal nozzles are arranged oppositely, and left and right spraying consists of pipes 9, 9. In the equipment and horizontal spraying, the shaped steel processing passage is divided into multiple sections in the transverse direction of the conveyance path, and the acid solution, submerged water, and drying air are sequentially supplied to each processing passage through a valve and a pump (not shown). The structure is such that the spray is applied to steel materials.

10 is a pickling tank that covers the acid spray zone, 11 is a running water tank that covers the submerged spray zone, and 12 is a cover for the drying zone.

Since the present invention is constructed in this way, when a plurality of various shaped steel materials are first brought into the acid spray zone 5, each shaped steel material is sprayed in the vertical direction by a device and the horizontal direction by a device. The steel materials are individually transported at the same speed through a plurality of processing passages, during which acid solution is sprayed over the entire surface of each steel material.

The acid solution adhering to the steel material is applied with a blowing force to quickly remove oxides, while flowing down the steel wall surface one by one, and immediately returned to the pickling tank.

In this way, a plurality of steel materials are pickled at once with high efficiency.

Processing can be performed with high efficiency in the submerged spray zone 6 and the drying zone 7 as well.

In the above embodiment, the horizontal spraying device and the vertical spraying device in each processing zone are arranged every other device along the conveyance path, but as shown in FIG. For the pipe 8 and the lower spray, a pipe 9 is branched from the pipe 8' for the left and right spray, and for this spray, the pipe 9 is equipped with a nozzle for horizontal spray, and the nozzle is placed at the same position for spray in both directions. It is also possible to do so.

Further, the treatment action can be more effectively carried out if the nozzles of each spraying device are arranged at an angle with respect to the pipe, as shown in FIG.

As described above, according to the present invention, a large number of steel sections can be pickled, washed, and dried at the same time, and has great industrial value.
