The structural form of a pickling tank and a rinsing tank used in the cold-rolling and pickling process section in China at present generally adopts a PPH (polymer propylene homopolymer) plate to manufacture a pickling tank body, the PPH plate has the advantages of stronger corrosion resistance, lower heat conduction, light weight, corrosion resistance, temperature resistance, lower heat conduction and the like compared with a steel plate, and meanwhile, as acid-resistant bricks or granite do not need to be built in the tank, the construction time can be shortened; the weight of the equipment is greatly reduced, and the basic investment of the equipment is reduced. But the strength of the pickling tank is poorer than that of a steel plate, the thermal expansion amount is large, and the length of the pickling tank body is longer, so that the tank body is easy to deform in the installation process of the PPH pickling tank. Traditional installation adopts preparation rectangle frame formula hoist to carry out the hoist and mount of PPH descaling bath, because hoist structural design length is not enough, causes hoist and mount rigging to become the tilt state among the hoist and mount process, forms the side direction extrusion to the cell body and causes PPH descaling bath to warp the damage easily.
For how to avoid damaging the tank body in the hoisting process, the CN 204138773U-pickling bath hanger of the strip steel pickling line comprises a main hook support, a main beam, secondary beams, connecting beams, reinforcing beams and a pickling bath lifting hook, wherein the two secondary beams are arranged in parallel, the middle of the two secondary beams is connected through the main beam, the two sides of the two secondary beams are respectively connected with one connecting beam, the reinforcing beams are respectively connected between the two sides of the main beam and the secondary beams, the inner parts of the two ends of the secondary beams are respectively embedded with a hanging plate, and the two ends of the hanging plate extend out of the two sides of the secondary beams and are provided with the pickling bath lifting hook; the main hook support is arranged on the upper portion of the main beam and comprises two lug plates vertically arranged on the upper portion of the main beam, the two lug plates are connected through a pin shaft and fixed through two bolts, and a chain is further arranged on the main hook support.
However, the technical scheme is suitable for hoisting the steel pickling tank, and the steel pickling tank is different from the pickling tank made of PPH materials in structural form, weight and strength. Meanwhile, the comparison document 1 is in the form of a rectangular frame, which has a complex structure and also has the problem of inconvenient construction, such as: reference 1 is provided with a pickling tank hook on the secondary beam, and is directly connected with the pickling tank body using a hoisting rigging. Such a design requires changing the overall dimensions of the pickling tank, making it difficult to install the pickling tank and also requiring cutting the lifting rigging from the pickling tank.
