Embodiment Construction

[0029] The present invention provides a rolling and backing bearing method using a medium cooling and lubricating rolling mill process. Since one medium is used, there is no problem that the lubricating and cooling effect is reduced due to the mixing of different lubricating mediums.

[0030] The lubricating and cooling method of the bearing provided by the present invention is to use the emulsion as the medium for lubricating and cooling; the emulsion circulation device is used to supply the liquid to the backing bearing, the roll and the plate to be rolled. The emulsion used is an anti-rust emulsion with good lubricity and super cooling capacity. The kinematic viscosity of the rolling oil (at 40°C): 40-70mm 2 / s, preferably 60mm 2 / s; saponification value=(11 0~190) mgKOH / g, preferably 150 mgKOH / g; oil content in the emulsion > 1%, preferably 3%. Specifically, select the QUAKEROL emulsion of the U.S. Quake (QUAKER) company, preferably QUAKEROLC77-XD, QUAKEROL C79-XD and RO...

Abstract

The present invention is bearing lubricating and cooling method and device, and features utilizing emulsion as lubricating and cooling medium and adopting an emulsion circulating device to provide the bearing, roller and the rolled plate with emulsion. The present invention can meet different lubricating and cooling requirements of rolling process in a two-stage paper belt filtering mode and has the pressure, flow rate, temperature, concentration and other parameters of the emulsion separately adjustable. The present invention can cool bearing, roller and the rolled plate effectively, save lubricating and cooling medium, improve rolled plate quality, prolong the service life of the bearing and make best use of the rolling machine.

Description

technical field [0001] The invention relates to the field of mechanical lubrication and cooling, in particular to a method and device for lubricating and cooling bearings. Background technique [0002] At present, lubricating oil or grease is generally used for lubricating and cooling of bearings. Lubricating oil is generally used for high temperature and dusty steel rolling equipment, and the bearing is lubricated by a circulating lubrication device. Figure 1 shows a lubricating and cooling device for the backing bearing of the Sendzimir rolling mill --- oil mist lubrication and cooling device I. The rolling pressure generated by the working rolls of the Sendzimir rolling mill passes through a series of larger support rolls, and finally The force is transmitted to the frame through the backing bearing, so the lubrication and cooling of the backing bearing are very important. Usually, oil is used as the medium to reduce the friction between the bearings, protect the bearing ...
