Description

Technical Field

[0001] The utility model relates to the field of steel rolling equipment, in particular to a rolling non-magnetic steel cooling device. Background Art

[0002] Steel rolling is a pressure processing process that changes the shape of the steel billet between rotating rollers. The purpose of steel rolling is the same as other pressure processing. On the one hand, it is to obtain the required shape, and on the other hand, it is to improve the quality of the inside of the steel billet. Steel rolling is divided into hot rolling and cold rolling. The difference is that the hot-rolled steel billet needs to be cooled after rolling. The common cooling method is to use cooling water spray. During spray cooling, the high-temperature cooling water contacts the steel billet and vaporizes to produce a large amount of steam. These steams will increase the humidity in the workshop, affect the equipment life in the workshop, and cause a waste of water resources. Therefore, it is particularly necessary to develop a rolling non-magnetic steel cooling equipment that can reduce the air humidity in the workshop and save water resources. Summary of the invention

[0003] The utility model aims to provide a rolling non-magnetic steel cooling device, which has the advantages of being able to reduce the air humidity in a workshop and saving water resources.

[0009] Preferably, a stainless steel protective net is provided in the protective cover.

[0010] Compared with the prior art, the beneficial effects are:

[0011] The utility model utilizes a primary cooling unit and a secondary cooling unit to perform two cooling operations on the rolled steel billet. During the first cooling operation, the high-temperature steel billet vaporizes cooling water, and the generated steam is introduced from a protective cover into a condenser for condensation to recover water, thereby reducing waste of water resources and preventing damage to equipment caused by excessive humidity in the workshop. During the secondary cooling operation, the cooling water cannot be completely vaporized due to the lowered temperature of the steel billet, and a water collecting pool is used to collect and reuse the water, thereby reducing waste of water resources.

[0018] During the first cooling, the high-temperature steel billet vaporizes the cooling water, and the generated steam is introduced from the protective cover 2 through the induced draft fan 3 to the condenser for condensation and water recovery, thereby reducing the waste of water resources and avoiding excessive humidity in the workshop. During the secondary cooling, the temperature of the steel billet is lowered and the cooling water cannot be completely vaporized. The water is collected and reused in the water collection tank 12.
