Application of backup rolls

The support roller is a roller widely used in industrial production. It has good supporting force, can support various raw materials, and enhance the efficiency of industrial production. Support rollers can be installed on various equipment, such as extruders, printing machines, heat sealing machines, separators, distribution machines, etc., to support the transportation of raw materials or finished products, keep them flat and fixed, and ensure smooth industrial production.

Selection of backup rolls

The selection of the backup roll is also very important, the quality of the backup roll directly affects the industrial production efficiency and product quality. First of all, the specifications should be considered. Generally, the appropriate specifications should be selected according to the characteristics of the raw materials and the installation space of the industrial equipment. Secondly, the material of the support roller should be considered. Generally speaking, the material should have good wear resistance and corrosion resistance to ensure its service life and smooth industrial production. In addition, surface treatment is also very important. Surface treatment can enhance the supporting force of the support roll, making the raw material run more smoothly on the support roll, which is beneficial to industrial production.

Back-up rolls play an important role in industrial production, correct selection and use is the key to ensuring industrial production efficiency and product quality, when selecting, factors such as specifications, materials, and surface treatment should be considered to ensure that it can meet the needs of industrial production .

Introduction of support roller

The support roller is an important part that is often used in mechanical equipment. Its main function is to support and protect the transmission parts to meet specific motion requirements and improve the overall operating performance of the transmission. The support roller can be divided into rolling and bearing, among which the supporting force of the rolling support roller is stronger, but it is easy to cause friction, which will affect the smoothness of operation; while the supporting force of the bearing support roller is weak, but it can effectively reduce friction and improve the transmission. sports performance.

Precautions for use of backup rollers

When using the backup roller, the specification of the backup roller must be determined first. Generally speaking, the specification of the backup roller is related to the speed of the transmission device. The higher the speed, the larger the specification. In addition, it is also necessary to determine whether to choose a rolling support roller or a bearing support roller according to the actual situation of the transmission device. Generally speaking, a transmission device with a higher rotational speed should use a rolling support roller, while a transmission device with a lower rotational speed should use a bearing support roller.

In addition, when installing the support roller, pay attention to the gap between the support roller and the transmission part. Generally speaking, the gap between the support roller and the transmission part should not be too large, otherwise it will affect the operation performance of the transmission device; If the gap is too small, the support roller will be over-tightened, which will affect the support force.

Maintenance of backup rollers

After the backup roller is used for a period of time, its surface will be rusted, so the backup roller should be cleaned and maintained regularly to reduce the wear and tear of the backup roller and prolong its service life. When cleaning the support roller, you can use a cotton cloth dipped in cleaning solution, and then wipe it clean; in addition, you can apply a layer of lubricating oil on the surface to prevent the surface from being worn and rusted.

In addition, the service life of the backup roller is also related to the correctness of the installation. Therefore, when installing the backup roller, it is necessary to carefully check the shape and specification of the backup roller and whether the gap between the backup roller and the transmission parts meets the requirements. The correctness can make the service life longer and more durable.

Product advantage

The world No. 1 in crude steel production steel plant, over 70% of the HSS for bar and wire are from us.

LMM high-speed steel rolls have higher steel passing per groove (times) due to their good wear resistance, which saves roll changing time, improves rolling mill operation rate, reduces roll consumption, and improve the overall efficiency of the factory.
Generally, the amount of steel passing in a single groove (times) is 3 to 5 times that of cast iron rolls.
