Lubricating system of cold reducing mill

Abstract

The invention discloses a lubricating system of a cold reducing mill which comprises an oil tank and is characterized in that a setting tank, an oil cleaning tank and an oil suction tank are arranged in the oil tank. The setting tank is internally provided with a U-shaped loop, and an oil return opening and an oil suction opening are arranged on the setting tank. The oil suction opening is connected with a sewage pump which is connected with an oil inlet of a flat bed filter. The oil inlet of the flat bed filter is arranged on the flat bed filter. The flat bed filter is connected with the oil cleaning tank. A baffle plate is arranged between the oil cleaning tank and the oil suction tank. The oil suction tank is internally provided with a spiral pump. The spiral pump is connected with an oil supply opening. The oil suction tank is provided with a water inlet and a water outlet. The setting tank and the oil suction tank are further provided with drain outlets. The spiral pump is connected with a pipeline filter. The lubricating system has the advantages of improving the cleanness of oil, better recycling the lubricating oil, reducing unnecessary waste on resources, enabling the structure of a lubricating oil station to be compact, reducing the space of an oil cellar as much as possible and saving the civil engineering cost.

Description

technical field [0001] The invention relates to the field of lubricating systems, in particular to the lubricating system of a cold rolling mill. Background technique [0002] In the production process of steel pipes, whether clean lubricating oil can be provided to the parts that need to be lubricated in the cold rolling mill is beyond doubt for improving the quality of steel pipes. The original lubrication system of this type is to excavate a sedimentation tank separately in the underground oil depot. The flat bed filter is placed above the sedimentation tank, and the lubricating oil station is placed next to the sedimentation tank. This type of system occupies a large area and requires high civil engineering costs. The oil cannot be recovered effectively, and the pollution to the environment is also relatively large. Moreover, in the original lubrication system of the cold rolling mill, the filtration effect is not good, resulting in poor cleanliness of the lubricating o...

The original lubrication system of this type is to excavate a sedimentation tank separately in the underground oil depot. The flat bed filter is placed above the sedimentation tank, and the lubricating oil station is placed next to the sedimentation tank. This type of system occupies a large area and requires high civil engineering costs. The oil cannot be recovered effectively, and the pollution to the environment is also relatively large

Moreover, in the original lubrication system of the cold rolling mill, the filtration effect is not good, resulting in poor cleanliness of the lubricating oil, which has a great impact on the production quality of the steel pipe, and the waste caused by the unreasonable layout of the oil station has always been a common problem.
