Abstract
The invention discloses a rubber protection water seal for a rolling mill supporting roll. The water seal comprises a seal ring and a seal lip; the seal ring and the seal lip are of an integrated structure, the seal lip is arranged at one end of the seal ring, the seal lip inclines in the axial direction of the seal ring, the seal ring and the seal lip are circular arcs larger than 180 degrees in the circumference direction, a steel strip is further wrapped by the seal ring, and stretches out of the seal ring, the two ends of the steel strip are each welded with a nut, and a bolt penetrates the two nuts; the rubber protection water seal is fixed to the position between a bearing pedestal and the rolling machine supporting roll; when the rolling machine supporting roll rolls a steel plate, the protection water seal can be conveniently and firmly fixed to the supporting roll bearing pedestal through the locking bolts, and the stable seal structural form of the protection water seal can be still kept under the long-term large water flow and high water pressure impact; when axial moving of the supporting roll is large, an elastic seal structure own by wear-resisting rubber can effectively achieve the dynamic seal compensation effect, and the service life of the protection water seal can be effectively prolonged.
Description
Technical field
The present invention relates to during steel mill's Mill work, needing substantial amounts of water to carry out cooling protection to operation roll of mill,
For preventing from leading to milling train water seal seal failure because of the larger axial float of backing roll, and then lead to inside backing roll filmatic bearing
Enter water excess, accordingly, it is desirable to provide a kind of Mill preventing rubber water seal that can effectively carry out sealing compensation.Rubber
The special structure design of protection water seal ensure that sealing compensation effect and the safety loaded and unloaded and convenience.
Background technology
With social development it is desirable to hot rolled steel plate requires capability and performance more homogeneous steady while thickness is constantly thinner
Fixed, promote that China's steel rolling mills equipment is constantly upgraded, milling train steel rolling process is continued to optimize.At this stage, China's steel
Under the background that seriously drug on the market for ferrum yield, the market competition is very fierce, the well stable operation of milling equipment, less unexpected event
Hinder number of times and shorten the repair time to improve production efficiency and product quality, reduction production cost, raising product competitiveness in the market
Have important practical significance.
Mill water seal is widely applied to steel industry hot-rolling supporting roll, heavy and medium plate mill backing roll, Wide and Thick Slab
Mill, hot rolling technique has the particularity of itself, during backing roll work, because the axial float of backing roll is larger
When, there is seal failure situation once in a while in the original water seal of backing roll, lead to backing roll filmatic bearing inner inlet, if rolling mill bearing
Interior water inlet exceedes safety operation specified value, gently then stops production, heavy then most likely result in backing roll or bearing block is scrapped, and causes weight
Big economic loss (direct economic loss of a set of support roller is more than million yuan), now, national cut deal, Wide and Thick Slab, cold and hot
Roll producing line production capacity recoverable amount more than hundred million tons, therefore, how to take precautions against water seal inefficacy and be extremely important.
, in rolled plate, in roughing process section, pre- steel billet of pricking is thicker for Mill, backing roll roll-force and bear
Larger from the impact of steel billet, there is play axially and radially in backing roll, the radial-play of backing roll is to water seal seal failure shadow
Ring relatively light, backing roll axial float is larger on affecting on water seal seal failure, and backing roll axial float leads to backing roll and water seal
Sealing contact surface separates, and leads to original water seal seal failure, protects installing and using of water seal, when original water seal seal failure,
Protection water seal can effectively provide sealing compensation.
One of which guard method is on back-up chock top, fixes semicircle iron sheet with less bolt, to reach
When backing roll works, semicircle iron sheet first blocks to a large amount of cooling waters, so, reaches at backing roll and water seal sealing surface
Discharge reduction and hydraulic pressure reduce.This guard method exists during using deposits a little as follows：1, after a period of time, iron sheet
Penetrated by water impact, block action deprivation；Additionally, by less bolt semicircle relatively difficult to achieve iron sheet work operationally
Shape, also makes occlusion effect have a greatly reduced quality.2 it is desirable to circular iron sheet can not with key equipment position directly contacts such as backing rolls,
With antisitic defect key equipment, therefore circular iron sheet can only play rough effect of blocking, still have substantial amounts of water slug to arrive to water
At backing roll and water seal sealing surface, this way is produced effects less.3, circular iron sheet can not have and stretch with backing roll directly contact
Contracting and palette, do not become dynamic palette face between backing roll and iron sheet.
