Definitions

  • This invention relates generally to continuous hot rolling bar mills, and is concerned in particular with a system and method for delivering the hot rolled products of such mills to a cooling bed.
  • hot rolled bar products exit the last mill stand, and are subjected to cooling by being passed through one or more water boxes.
  • the bar products are then subdivided into bar segments by a dividing shear, which includes a switching mechanism for alternately directing the bar segments to one or the other of two downstream delivery paths leading to the cooling bed.
  • Pinch roll units, friction pads, or the like serve to decelerate the bar segments traveling along the delivery paths, with the result that the bar segments gradually slide to a halt before being laterally transferred onto the cooling bed.
  • Relatively high tonnage rates can be achieved with this type or arrangement when the mill is rolling larger product sizes, e.g., those having diameters above about 10.0 to 12.0 mm. These larger products have enough column strength to resist buckling as they are being pushed through the water boxes at relatively high mill delivery speeds on the order of 10 to 30 m/sec.
  • a single strand mill rolling 8.0 mm rod for delivery to a laying head can operate at a delivery speed of 60 m/sec or greater, yielding a capacity of 85 tons/hour.
  • a similar mill rolling 8.0 mm bar for delivery to a cooling bed must necessarily roll at a significantly reduced delivery speed of about 32 m/sec with a reduction in capacity to about 45 tons/hour.
  • the reduced delivery speed for bar products is due in large part to the inability of conventional bar handling systems to bring faster moving products to a halt before they are transferred laterally onto the cooling bed.
  • An objective of the present invention is to increase the tonnage rate at which mills are able to roll bar products, in particular smaller product sizes, e.g., those having diameters smaller than about 12.0 mm.
  • a companion objective of the present invention is to raise the speed at which the smaller bar products are delivered from the mill, and to then decelerate such bar products before they are cooled in the water boxes prior to being delivered to the cooling bed.
  • hot rolled bar products are subdivided by a dividing shear into bar segments, and the bar segments are alternately directed to one or the other of two downstream intermediate paths.
  • a switch on each intermediate path then alternately directs the bar segments to one or the other of two downstream delivery paths leading to the cooling bed.
  • the bar segments traveling along the four delivery paths are subjected to at least two deceleration stages.
  • the first deceleration stage operates to slow the bar segments to an intermediate speed lower than the speed at which the bar products are delivered from the mill, and the second deceleration stage operates to further slow the bar segments to a lower speed suitable for delivery to the cooling bed.
  • the bar segments are cooled between the first and second deceleration stages while they are traveling at the intermediate speed.
  • Claim 1 provides a system for receiving a hot rolled bar product from a rolling mill, and for delivering the bar product to a cooling bed, said apparatus comprising: shear means for subdividing the bar product into bar segments and for alternately directing the bar segments to one or the other of two downstream intermediate paths for continued travel thereon; switch means on each of said intermediate paths for alternately directing bar segments traveling thereon to one or the other of two respective downstream delivery paths for continued travel thereon to said cooling bed; and decelerating means for slowing the bar segments traveling along said delivery paths.
  • the system further comprises cooling means for cooling the bar segments traveling along said delivery paths.
  • said decelerating means comprises first and second decelerating means spaced one from the other along said delivery paths, said first decelerating means being operable to slow the bar segments to an intermediate speed lower than the speed at which the bar product is delivered from said rolling mill, and said second decelerating means being operable to further slow the bar segments from said intermediate speed to a lower speed suitable for delivery to said cooling bed.
  • the distance between said first and second decelerating means is preferably greater than the length of said bar segments.
  • system may further comprise cooling means for cooling the bar segments traveling along said delivery paths.
  • said cooling means comprises first and second cooling means spaced one from the other along said delivery paths, said first cooling means being located upstream of said first decelerating means, and said second cooling means being located between said first and second decelerating means.
  • the distance between said first decelerating means and said second cooling means may be less than the length of the bar segments.
  • said decelerating means comprise pinch roll units.
  • said cooling means comprises water boxes for applying water to the bar segments.
  • Claim 10 provides a system for receiving a hot rolled bar product from a rolling mill, and for delivering the bar product to a cooling bed, said apparatus comprising:
  • claim 11 provides a system for receiving a hot rolled bar product from a rolling mill, and for delivering the bar product to a cooling bed, said apparatus comprising:

  • the invention provides a system for receiving a hot rolled bar product from a rolling mill, and for delivering the bar product to a cooling bed, said apparatus comprising: shear means for subdividing the bar product into bar segments and for alternately directing the bar segments to one or the other of two downstream intermediate paths for continued travel thereon; switch means on each of said intermediate paths for alternately directing bar segments traveling thereon to one or the other of two respective downstream delivery paths for continued travel thereon to said cooling bed; first and second decelerating means spaced one from the other along said delivery paths, said first decelerating means being operable to slow the bar segments to an intermediate speed lower than the speed at which the bar product is delivered from said rolling mill, and said second decelerating means being operable to further slow the bar segments from said intermediate speed to a lower speed suitable for delivery to said cooling bed; and first and second cooling means spaced one from the other along said delivery paths, said first cooling means being located upstream of said first decelerating means, and said second cooling means being located between said first and second de
  • Claim 14 provides a method of receiving a hot rolled bar product from a rolling mill, and delivering the bar product to a cooling bed, said method comprising: subdividing the bar product into bar segments and alternately directing the bar segments to one or the other of two intermediate paths for continued travel thereon; alternately directing bar segments traveling along said intermediate paths to one or the other of two respective delivery paths for continued travel thereon to said cooling bed; and decelerating the bar segments traveling along said delivery paths.
  • the method further comprises cooling the bar segments traveling along said delivery paths.
  • said bar segments are decelerated in two stages along said delivery paths, said first decelerating stage operating to slow the bar segments to an intermediate speed lower than the speed at which the bar product is delivered from said rolling mill, and said second decelerating stage operating to further slow the bar segments from said intermediate speed to a lower speed suitable for delivery to said cooling bed.
  • the second decelerating stage occurs after the first decelerating stage has been completed.
  • the method preferably further comprises cooling the bar segments traveling along said delivery paths.
  • the method is preferably carried out such that said cooling occurs while said bar segments are undergoing deceleration at said first stage.
  • a method of receiving a hot rolled bar product from a rolling mill, and delivering the bar product to a cooling bed comprising: subdividing the bar product into bar segments and alternately directing the bar segments to one or the other of two intermediate paths for continued travel thereon; alternately directing bar segments traveling on said intermediate paths to one or the other of two respective delivery paths for continued travel thereon to said cooling bed; and subjecting the bar segments traveling along said delivery paths to a two stage deceleration, the first deceleration stage being operable to slow the bar segments to an intermediate speed lower than the speed at which the bar product is delivered from said rolling mill, and the second deceleration stage being operable to further slow the bar segments from said intermediate speed to a lower speed suitable for delivery to said cooling bed.
  • Claim 21 provides a method of receiving a hot rolled bar product from a rolling mill, and delivering the bar product to a cooling bed, said method comprising: subdividing the bar product into bar segments and alternately directing the bar segments to one or the other of two intermediate paths for continued travel thereon; alternately directing bar segments traveling along said intermediate paths to one or the other of two respective delivery paths for continued travel thereon to said cooling bed; subjecting the bar segments traveling along said delivery paths to a two stage deceleration, the first deceleration stage being operable to siow the bar segments to an intermediate speed lower than the speed at which the bar product is delivered from said rolling mill, and the second deceleration stage being operable to further slow the bar segments from said intermediate speed to a lower speed suitable for delivery to said cooling bed; and cooling the bar segments traveling at said intermediate speed.
  • a system in accordance with the present invention is shown between the last roll stand 10 of a continuous hot rolling bar mill and a conventional carryover cooling bed 12.
  • Bar product exiting from roll stand 10 along path P A is passed through a series of water boxes 14, after which it is subdivided into bar segments by a dividing shear 16.
  • the shear 16 which can be of a conventional design known to those skilled in the art, includes a switch mechanism which alternately directs the subdivided bar segments to one or the other of two downstream intermediate paths P B , P C .
  • a switch 18 on intermediate path P B then serves to alternately direct the bar segments to one or the other of two downstream delivery paths P D , P E , and a switch 20 on intermediate path P C similarly directs product segments alternately to one or the other of two downstream delivery path P F , P G .
  • the side-by-side sets of delivery paths P D , P E and P F , P G lead through a series of water boxes 22 to pinch roll units 24, 26, then around a side loop defined in part by two opposed 180° curves C 1 , C 2 . Curve C 1 is partially formed by a removable guide section 28.
  • the side loop includes water boxes 30, and at curve C 2 , the two sets of delivery paths P D , P E and P F , P G are brought into vertical alignment before continuing to pinch roll units 32, 34 preceding the cooling bed 12.
  • single tier guide units 36, 38 with laterally spaced guide pipes 40 are employed to direct the bar segments along the laterally disposed and vertically offset sets of delivery paths P D , P E and P F , P G , and two tier trough units 42 are employed to direct the bar segments when the two sets of delivery paths are aligned vertically.
  • pinch roll unit 32 has two sets of pinch rolls 44, 46 aligned respectively with delivery paths P G and P F
  • pinch roll unit 34 also has two sets of pinch rolls 48, 50 aligned respectively with delivery paths P D and P E .
  • Each set of pinch rolls is independently driven via drive shafts 52, a gear box 54 and drive motors 56. The pinch rolls are driven at speeds selected to effect an appropriate deceleration of bar segments frictionally gripped therebetween.
  • the pinch roll units 24, 26 are similarly constructed, but arranged slightly differently for alignment with the laterally disposed and vertically staggered guide paths.
  • Pinch roll units 24 and 26 will then operate to initially decelerate the bar segments to a lower intermediate speed of about 30 m/sec.
  • the bar sections will be directed by the curved guide section 28 around the side loop and through the water boxes 30.
  • the linear distance between the pinch roll units 24, 26 and the water boxes 30 is preferably less than the length of the bar segments.
  • the water boxes 30 will operate to cool the bar segments down to about 500-600°C before they negotiate curve C 2 .
  • the pinch roll units 32, 34 will then operate to further decelerate the bar segments to a speed of about 3-8 m/sec., which will allow the bar segments to slide to a halt at the entry end of the cooling bed 12. From here, transfer mechanisms (not shown) will operate to shift the bar segments laterally onto and across the cooling bed where they will undergo further cooling before reaching the delivery side of the bed.
  • the system of the present invention is extremely flexible in that it can accommodate a wide range of products at beneficially high tonnage rates.
  • Smaller diameter products e.g., those ranging in diameter from 6.35 to 12.0 mm can be handled at relatively high mill delivery speeds on the order of 60 to 32 m/sec. by passing freely through the water boxes 22 and undergoing initial deceleration by pinch roll units 24, 26 before cooling is effected in water boxes 30.
  • Larger diameter products exceeding 12.0 mm in diameter and exiting the mill at slower speeds below about 30 m/sec. can be cooled in the water boxes 22 before initial deceleration by pinch roll units 24, 26.
  • two systems of the type depicted in Figure 1 can be arranged side by side to feed the same cooling bed.
