Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, in particular to a lubricating oil cooling device for a hot rolling mill. Background Art

[0002] Hot rolling mills are important equipment for processing metal materials. They are mainly used to process large metal billets into required plates, strips, profiles and other products through pressure and temperature. During processing, the metal billet is first preheated to an appropriate temperature, and the preheated metal billet is passed through the roller group of the hot rolling mill to change its cross-sectional shape and size to achieve the processing effect. It can be seen that the hot rolling mill is in a high-temperature environment when working. At present, in order to avoid the lubricating oil used for lubricating and cooling key components such as the rolls in the hot rolling mill from being in a high-temperature state for a long time in this high-temperature environment and affecting its service life, the lubricating oil needs to be cooled. The traditional cooling method using air cooling is to blow cold air through the lubricating oil and achieve a cooling effect through heat exchange through air convection. However, since the air flow acts on the lubricating oil for a short time, the cooling effect is poor, and the internal impurities of the lubricating oil in the existing technology increase with the increase of usage time, resulting in poor lubrication of the lubricated parts and increased wear.

[0003] To this end, we provide a hot rolling mill lubricating oil cooling device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a hot rolling mill lubricating oil cooling device, which increases the airflow action time by allowing the lubricating oil to flow through a number of transverse plates, and filters impurities in the lubricating oil through filter plates, thereby solving the problem that the airflow in the prior art acts on the lubricating oil for a short time, resulting in poor cooling effect, and that the lubricating oil in the prior art has an increased amount of internal impurities as the use time increases, resulting in poor lubrication of the lubricated parts and increased wear.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a hot rolling mill lubricating oil cooling device, comprising a cooling mechanism, the cooling mechanism comprising a cooling box, a plurality of horizontal plates are arranged equidistantly from bottom to top on the upper side of the interior of the cooling box, the plurality of horizontal plates are staggered in the vertical direction, a vertical bar is fixed on one side of the upper wall of the horizontal plate connected to the cooling box, a flow groove is opened on the lower wall of the vertical bar, and a fan is fixed on the upper wall of the cooling box;

The flow grooves 104a are used to prevent the lubricating oil from flowing quickly. When the lubricating oil passes through the flow grooves 104a, the lubricating oil cannot pass through quickly due to the low height of the flow grooves 104a. At this time, the lubricating oil diffuses in the front and rear directions and then passes through the flow grooves 104a, so that the lubricating oil can expand the contact area with the horizontal plate 103, increase the cooling area of ​​the lubricating oil, and enhance the cooling effect of the lubricating oil. A fan 101 is fixed to the upper wall of the cooling box 102 for generating airflow to cool the lubricating oil.

[0031] Specifically, a dust cover 101a is fixed to the air inlet end of the fan 101 to prevent dust and impurities from being mixed in the air flow entering the interior of the cooling box 102, and the air outlet end of the fan 101 is in communication with the interior of the cooling box 102;

With the above arrangement, the amount of lubricating oil inside the cooling box 102 can be directly viewed through the transparent window 102d, and the amount of liquid in the cooling box 102 is detected by the liquid level sensor 102g. When the amount of liquid is higher than the set value, the controller 102b controls the audible and visual alarm 102a to work and alert people to avoid the lubricating oil from overflowing from the air outlet slot 102f.

At this time, the lubricating oil passes through the top flow groove 104a and flows to the next horizontal plate 103. The lubricating oil moves toward the lower side of the inside of the cooling box 102 in a serpentine trajectory. During this period, the airflow generated by the operation of the fan 101 acts on the lubricating oil to cool the lubricating oil. As the fan 101 continues to work, the airflow carries the heat in the lubricating oil through the air outlet groove 102f and is discharged to the outside of the cooling box 102 to achieve a cooling effect on the lubricating oil.
