Description
Technical field
, it is necessary to which substantial amounts of water carries out cooling protection to operation roll of mill when being worked the present invention relates to steel mill's Mill,
To prevent from causing milling train water seal seal failure because of the larger axial float of backing roll, and then cause inside backing roll filmatic bearing
Enter dilutional hyponatremia, accordingly, it is desirable to provide a kind of can effectively carry out the Mill preventing rubber water seal of sealing compensation.Rubber
The special structure design of protection water seal ensure that the security and convenience of sealing compensation effect and handling.
Background technology
With social development, it is desirable to which hot rolled steel plate requires that capability and performance is more homogeneous steady while thickness is constantly thinner
It is fixed, promote China's steel rolling mills equipment to obtain constantly upgrading, milling train steel rolling process and continued to optimize.At this stage, China's steel
Iron yield is serious, and drug on the market, under market competition very fierce background, milling equipment it is well stable run, it is less unexpected therefore
Hinder number of times and shorten the repair time to improving production efficiency and product quality, reduction production cost, improving 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, when backing roll works, 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, cause 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 again
Big economic loss (direct economic loss of a set of support roller is more than million yuan), it is now, national cut deal, Wide and Thick Slab, cold and hot
Producing line production capacity recoverable amount is rolled more than hundred million tons, therefore, how to be taken precautions against water seal failure and is extremely important.
Mill is in rolled plate, in roughing process section, and pre- steel billet of pricking is thicker, backing roll roll-force and bears to come
Impact from steel billet is larger, and backing roll has play axially and radially, and the radial-play of backing roll is to water seal seal failure shadow
Sound is lighter, and backing roll axial float on water seal seal failure on influenceing larger, and backing roll axial float causes backing roll and water seal
Sealing contact surface is separated, and causes original water seal seal failure, protects installing and using for 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, semicircle iron sheet to be fixed with less bolt, to reach
When backing roll works, semicircle iron sheet is first blocked to a large amount of cooling waters, so, is reached at backing roll and water seal sealing surface
Discharge reduction and hydraulic pressure reduction.Exist during this guard method use and deposit a little as follows：1, after a period of time, iron sheet
Penetrated by water impact, block action deprivation；In addition, the work by less bolt semicircle iron sheet relatively difficult to achieve operationally
Shape, also causes occlusion effect to have a greatly reduced quality.2, it is desirable to which circular iron sheet can not directly be contacted with the key equipment position such as backing roll,
With antisitic defect key equipment, therefore circular iron sheet can only play the rough effect of blocking to water, still have substantial amounts of water slug to arrive
At backing roll and water seal sealing surface, this way is produced effects smaller.3, circular iron sheet can not directly be contacted with backing roll, without stretching
Contracting and palette, do not become dynamic palette face between backing roll and iron sheet.
