Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described:

[0017] Such as figure 1 , figure 2 As shown, it is the installation position diagram of the cold-rolled steel wire back-up roll bearing seat waterproof method. The two ends of the back-up roll 1 are bearing seats 2, and the flange pressure plate 3 is installed on the inner side of the bearing seat 2, and the pressure plate fixes the waterproof rubber plate. 4. This rubber plate is to prevent the cooling medium from spraying onto the shaft, in an attempt to block the medium from entering the inside of the bearing seat. The actual effect is to reduce the amount of cooling medium splashed on the shaft, and it cannot prevent water from entering the bearing with the rotation of the shaft. seat. Be gas purge pipe 5 below waterproof rubber plate 4, with a circular tube of diameter 20mm, stew and make a ring, its diameter ring shaft is greater than the axle 50mm of back-up roll...

Abstract

The invention provides a waterproofing method for supporting roller bearing pedestals on a steel plate cold rolling line. An air purging pipe 5 is arranged at a position, located on the inner side of each bearing pedestal 2, below a water retaining rubber plate 4; an extremely thin wind line is formed towards a supporting roller; purging air 6 is sprayed to the shaft center line of the supporting roller 1 at an angle of 45 degrees, to form a compressed air barrier, namely liquid sputtered onto the section of shaft can be blown away by compressed air immediately, so that the liquid cannot enter the bearing pedestals 2 along with the rotation of the shaft; an air supply automatic system is additionally arranged on the air purging pipe 5; from start of spraying of a cooling medium pipe 7 to stop of spraying, the air supply system can be controlled; air is started to be purged immediately as long as a water path starts to spray water; and therefore, the waterproofing method can intelligently solve the problem of water entering the supporting roller bearing pedestals on the steel plate cold rolling line.

Description

technical field [0001] The invention relates to a method and device for waterproofing the bearing seat of a cold-rolled steel wire support roll, in particular to a method that can well solve the problem of water entering the bearing seat of a cold-rolled steel wire support roll, so that the cold-rolled steel wire support roll used on-line The problem of water ingress into the bearing seat has been completely cured. Background technique [0002] There are many rolls on the rolling mill of the cold-rolled steel plate line. The steel plate that needs to be rolled online is a cold plate. The temperature of the rolling mill is monitored at 60 degrees. In order to ensure that the roll is durable and does not deform, the temperature of the shaft must be strictly controlled. The roll is equipped with a high-pressure water spray head to spray a large amount of cooling medium on the roll and the rolled steel plate. The cooling medium is an emulsion, the composition is rolling oil + de...
