Problems solved by technology
The anti-corrosion of the surface of the corresponding facilities is easy to achieve, but it is extremely difficult for the internal anti-corrosion of the facilities. For example, the column steel structure composed of channel steel encased and welded, because the column steel structure has not achieved internal sealing, and it is difficult to achieve secondary anti-corrosion, so it is extremely difficult. Susceptible to corrosion, greatly reducing the service life of the facility

Embodiment Construction
[0017] Now illustrate structural features of the present invention in conjunction with accompanying drawing:
[0018] Such as figure 1 , 2 As shown: the hollow steel material 1 is formed by two channel steels arranged in parallel and connected by butt welding with the notches facing each other. According to the design requirements, the process of pouring cement for anticorrosion is as follows: firstly, channel steel one 11 and channel steel two 12 are butt welded to form a hollow cavity A, and the hollow cavity A is filled with cement, and the anticorrosion core 2 composed of poured cement is realized. Anticorrosion of the inner wall of the hollow chamber A.
[0019] The inner wall of the hollow cavity A is welded with a cone-shaped protruding ring 14 in the circumferential direction, and a plurality of the protruding rings 14 are arranged in sequence along the length direction of the channel steel. air hole 141 . The convex ring 14 is in the shape of a cone, which can fur...

The invention relates to the field of steel anti-corrosion technologies, in particular to an anti-corrosion steel structure. The anti-corrosion steel structure comprises hollow steel. Cement is poured into a cavity of the hollow steel, and anti-corrosion cores of the inner wall of the cavity are formed by the cement. The hollow steel is composed of first u-steel and second u-steel which are arranged parallelly and butt welded with notches oppositely embraced. According to the anti-corrosion steel structure, corrosion, caused by an acidic medium, to the inner wall of the cavity is prevented through full filling of the cement inside the hollow steel, so that not only is the anti-corrosion effect achieved, but also the intensity of the hollow steel is strengthened. In addition, in the later using process, anti-corrosion treatment to the inner portion of the hollow steel is not needed. The beneficial effects of the anti-corrosion steel structure are achieved once for all. The anti-corrosion steel structure has the advantages that the inner corrosion of an iron facility in the device area can be well achieved, and the service life of the facility is prolonged.
Description
technical field [0001] The invention relates to the technical field of steel material anticorrosion, in particular to an anticorrosion steel structure. Background technique [0002] In chemical production, the production of overflow ball mills and the cleaning of auxiliary equipment are usually completed by the production sewage after neutralization with acid and alkali. It is difficult to completely neutralize the production sewage in a short time. The sewage contains a small amount of acidic medium. The medium severely corrodes the iron devices, so only the corresponding equipment is protected against corrosion to reduce the corrosion of the equipment during cleaning by the acidic medium in the sewage. The anti-corrosion of the surface of the corresponding facilities is easy to achieve, but it is extremely difficult for the internal anti-corrosion of the facilities. For example, the column steel structure composed of channel steel encased and welded, because the column ste...
