Problems solved by technology

[0005] In view of this, the present invention aims to propose an oil-air lubrication system for rolling mills, which solves the inconvenience of changing a single roll when the satellite station supplies oil to the rolling mill, and when a single rolling mill or some bearing housings are not installed in place, the oil is blocked and the components are easily damaged. problems, further making the use of rolling mill equipment more convenient

Abstract

The invention provides an oil-air lubrication system of rolling mills. The oil-air lubrication system includes an oil-air lubrication station, a satellite station, a flat-roll rolling mill, a vertical-roll rolling mill and an oil liquid collection box. The satellite station includes a progressive distributor and an oil-air mixing block, and the oil-air lubrication station is connected with the progressive distributor in the satellite station. The progressive distributor is connected with the oil-air mixing block, a compressed air machine is connected with the oil-air mixing block in the satellite station, and the oil-air mixing block is provided with a plurality of output pipelines correspondingly. The output pipelines are equipped with flow regulating valves, one ends of the flow regulating valves are connected to the output pipelines of the oil-air mixing block, and the other ends of the flow regulating valves are connected to the oil liquid collection tank. The output pipelines of the mixing block are connected with rolling mill bearing seats. The oil-air lubrication system has the beneficial effects that the working status of the rolling mills can be flexibly adjusted, the rolling mills are prevented from working when the progressive distributor is jammed or the pipelines are not smooth, excess oil is simultaneously recovered and reused, the operation is simple, energy is saved, and efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of rolling mills, in particular to a rolling mill oil-air lubrication system. Background technique [0002] Oil-air lubrication is a new type of gas-liquid two-phase fluid cooling lubrication technology, which is more suitable for high temperature, heavy load, high speed, extremely low speed, and working conditions with cooling water and dirt invading lubrication points than traditional single-phase fluid lubrication technology In harsh occasions, the service life of the friction pair is greatly extended and the on-site environment is improved, so it is more and more widely used in the metallurgical industry. [0003] In the rolling mill equipment of section steel, plate and strip steel, usually one satellite station provides lubricating oil source for two or more rolling mill bearing housings, and the oil outlet pipe of each satellite station is connected to a bearing housing. The wear conditions are diffe...
