Finishing Mill Circulating Oil Lubrication

The core principle of thin oil lubrication is to use lubricating oil with good fluidity to form a uniform and continuous oil film on the surface of the friction pair of mechanical equipment. This layer of oil film is as high as a high. The effective cushion can effectively separate the friction surface, greatly reducing the direct contact between metals and the coefficient of friction.
When the mechanical equipment is running, the lubricating oil is constantly circulating and flowing, continuously taking away the heat generated by friction, and at the same time washing away the impurities such as metal chips generated on the friction surface, so as to achieve efficient lubrication, cooling and cleaning of the equipment, and effectively extend the service life of the equipment.

Thin oils have low viscosity and excellent flowability, and are quickly and evenly distributed to the various friction points of the finishing mill to form a stable and reliable oil film. This oil film can effectively reduce the coefficient of friction, reduce the wear and tear of the equipment, and ensure the efficient and stable operation of the equipment.
Compared with other lubrication methods, thin oil lubrication performs better under high-speed and heavy-load conditions, can withstand larger loads, and provides reliable lubrication guarantee for the high-load operation of the finishing mill.

During the rolling process of the finishing mill, a large amount of heat will be generated, which will have a serious impact on the performance and life of the equipment if it is not dissipated in time. During the circulating flow of thin oil, it can fully absorb the heat generated by friction and dissipate the heat through the cooler.
This efficient cooling capacity helps to maintain the normal operating temperature of the equipment, prevent the deformation and damage of parts caused by overheating, and improve the operational availability and stability of the equipment.

With the circulating flow of lubricating oil, it can rinse and take away the metal chips and impurities generated by the friction surface in time, so as to avoid the accumulation of these impurities inside the equipment, thereby reducing the wear and damage to the equipment.
Regular filtration and replacement of lubricating oil can further ensure the cleanliness of the lubricating oil, ensure the normal operation of the lubrication system, and prolong the service life of the equipment.

The 1850L finishing mill has a high running speed, which requires extremely high response speed and stability of the lubrication system. With its good fluidity and fast heat dissipation ability, the thin oil lubrication system can quickly adapt to the needs of high-speed transmission.
The stable oil film can remain intact at high speeds, effectively reduce vibration and noise, and provide strong support for the high-speed and stable operation of the finishing mill.

The thin oil lubrication system of 1850L finishing mill is mainly used in the equipment area of pinch rolls, crushing shear and other equipment before the finishing mill, providing reliable lubrication guarantee for the operation of these equipment and ensuring the accuracy and stability of its action.
In the area of the spinning machine and its pinch roll after the finishing mill, thin oil lubrication can effectively reduce the wear of the equipment, improve the spinning quality and pinch accuracy, and meet the process requirements of high-speed wire rod production。
The finishing mill and its transmission gearbox are the core components of the whole rolling process, and the thin oil lubrication system provides sufficient lubrication and cooling to ensure the stable operation of the equipment under high load and high speed, and to ensure that the quality of the rolled steel meets the standards.

Check the oil level of the lubricating oil regularly to ensure that the oil level is within the normal range. A low oil level can lead to insufficient lubrication and equipment failure; If the oil level is too high, it may affect the normal operation of the system and even lead to an oil spill.
Pay close attention to the quality of lubricating oil, and conduct regular sampling and testing, including viscosity, pH, moisture content, impurity content and other indicators. According to the test results, replace or replenish the lubricating oil in time to ensure that the performance of the lubricating oil meets the requirements.
Check the oil supply to each lubrication point to ensure that the lubricating oil can be evenly and smoothly supplied to each lubrication point. If it is found that the oil supply is not smooth or blocked, the cause should be investigated in time and cleaned or repaired.

Oil contamination is one of the common problems in thin oil lubrication systems, with the main contaminants including solid suspended particulates and liquid water. Particulate contaminants may come from metal powders, seal wear particles, filter material shedding, etc., generated during the operation of the finishing rolling system; Moisture can enter the fluid through leaks in the cooling system, damp air, etc.
In response to the problem of oil contamination, measures such as strengthening filtration, replacing filter elements regularly, and preventing moisture ingress can be taken. For example, an oil-water separation observation device is installed on the oil return pipe below the finishing stand to remove the water in the oil in time; Improve the filtration accuracy of the filter, clean and maintain the filter regularly.
When the oil supply pressure is unstable, it may be caused by oil pump failure, pipeline leakage, valve blockage, etc. The working status of the oil pump should be checked first to see if there are problems such as abnormal noise, vibration or insufficient flow; Then the pipeline is checked for leakage and the leakage point is repaired; Finally, check the opening and closing of the valve, clean up the impurities in the valve, and ensure that the valve works normally.
