Abstract
A guide for directing a hot rolled product along a path in a rolling mill comprising at least one annular roller arranged to contact the product. The roller is rotatably supported on a shaft by bearings defining an axial gap therebetween. Fluid is delivered under pressure into the gap and internal vanes respond to the thus delivered fluid by rotatably driving the rollers.
Description
- 1. Field of the Invention
- This invention relates generally to rolling mill roller guides, and is concerned in particular with an improved means for pre-spinning the guide rollers in advance of the arrival of a mill product therebetween.
- 2. Description of the Prior Art
- As disclosed in U.S. Pat. Nos. 6,151,946 and 4,373,367, it is known to pre-spin the rollers of rolling mill entry guides by impinging a pressurized fluid, typically cooling water, on vanes formed on the exterior sides of the rollers. The vanes are formed on both sides of the rollers so as to permit reversal of the rollers after they have operated for a period of time in one direction of rotation. The drawbacks to such arrangements include the costs associated with forming the vanes on both exterior sides of the rollers, the need to divert cooling water from other locations for dedicated application to the rollers, and the danger that externally applied cooling water may contaminate the roller bearings.
-
FIG. 1 is a plan view of a roller entry guide in accordance with the present invention; -
FIG. 2 is a horizontal sectional view on an enlarged scale taken through one of the guide rollers; -
FIG. 3 is a sectional view taken along line 3-3 ofFIG. 2 ; -
FIG. 4 is a view similar toFIG. 2 showing an alternative embodiment of the invention; and -
FIG. 5 is a sectional view taken along line 5-5 ofFIG. 4 . - The objective of the present invention is to provide an improved means for driving the guide rollers that avoids the aforementioned drawbacks of the prior art.
- In accordance with one embodiment of the present invention, a roller entry guide has mutually spaced annular rollers arranged to contact opposite sides of a product, e.g., hot rolled steel rod, moving at high speed along a path. The rollers are supported on respective shafts by bearings defining axial gaps therebetween. The gaps are surrounded by vanes carried by the rollers. A pressurized fluid, typically an oil mist, is delivered to the axial gaps via passageways in the shafts. The oil mist impinges on the vanes to rotatably drive the rollers, and also serves as a lubricant for the roller bearings.
- These and other features and attendant advantages of the present invention will now be described in greater detail with reference to the accompanying drawings, wherein:
- With reference initially to
FIG. 1 , a roller entry guide in accordance with the present invention is generally indicated at 10. The guide includes ahousing 12 supporting a pair ofarms 14 pivotally adjustable aboutaxes 16. The projecting distal ends of the arms carryannular guide rollers 18 rotatably mounted onrespective shafts 20. The guide rollers are arranged to contact opposite sides of a product, typically hot rolledsteel rod 22, moving at high speed along a path “P” into a roll stand (not shown). - With reference additionally to
FIGS. 2 and 3 , it will be seen that eachguide roller 18 is rotatably supported on itsrespective shaft 20 bybearings 24 defining anaxial gap 26 there between. The bearings preferably comprise roller bearings havinginner races 24 a fixed with respect to theshaft 20, andouter races 24 b fixed with respect to the interior of theroller 18. - A
spacer 28 is interposed between theinner bearings races 24 a. The spacer is surrounded by a series of vanes indicated typically at 30 and formed on an interior surface of theguide roller 18. An axially extendingpassageway 32 inshaft 20 is arranged to direct a flow of pressurized fluid toradial passageways 34 communicating with acircular passageway 36 formed by confronting grooves in theshaft 32 andspacer 28.Nozzles 38 in the spacer lead from thepassageway 36 and are arranged to direct the pressurized fluid against thevanes 30 to thereby rotatably drive and pre-spin therollers 18. The pressurized fluid is advantageously an oil mist which serves the added purpose of lubricating thebearings 24. - The embodiment shown in
FIGS. 4 and 5 is largely identical to that shown inFIGS. 2 and 3 , except that thevanes 30′ are formed on the interior of abushing 40 pressed into the interior of theguide roller 18. - In light of the foregoing, it will now be understood that in accordance with the present invention, each roller need only be provided with one array of internal vanes. The rollers are rotatably driven by the same pressurized fluid that also serves as the lubricant for the roller bearings. No potentially troublesome external application of cooling water is required, and the internal vanes can serve to rotate the rollers in either direction, thus enabling the rollers to be reversed.
- While the internal pre-spinning and lubrication system of the present invention has been described with reference to roller entry guides, it should be understood that the same concept can be utilized to pre-spin and lubricate rollers in other rolling mill applications where rollers are used to guide the hot rolled product along curved paths. One non-limiting example of such an application would be to pre-spin and lubricate the rollers of a rollerized guide directing the hot rolled product into an inclined laying head.
