Definitions

  • modern high-production vertical mills are provided with a pair of cooperative metal reducing rolls, which in many cases are formed with a series of different shape or size grooves or passes along their lengths.
  • each of the rolls which are 30 inches in diameter and 48 inches in body length, has two similar size passes for rolling billets and two different size passes for rolling rounds.
  • the billet passes are also employed for edging skelp slabs, which is the third product produced by the mill.
  • the mills are provided with a mechanism for vertically adjusting the rolls so that each pass thereof can be positioned to receive a workpiece passing along a fixed horizontal steel line.
  • the rolls must be adjusted vertically a relatively long distance of 48 inches.
  • a still further limitation of present-day mills is in regard to the initial investment cost and the cost of maintaining a roll inventory adequate to cover the various products produced by the mills.
  • the necessity of having to adjust the rolls a relatively great distance substantially increases the cost of manufacturing the mills.
  • the drives, spindles and housings of the mills must be designed to allow for the vertical movement of the rolls.
  • the long, large diameter rolls are expensive in themselves, let alone the added cost of having to provide large housings, bearings, chocks, etc. that these rolls require.
  • One form of the present invention relates to an improved vertical mill which will either completely or substantially reduce the detrimental effects of each and every one of the enumerated disadvantages of present-day mills.
  • the improved mill provides a pair of rotatable spacedapart turrets arranged on parallel vertical axis carrying two roll assemblies spaced 180 apart. These rolls, in
  • the preferred form are provided with only a single pass and, consequently, theirlengths and diameters are appreciably smaller than the rolls of present-day mills.
  • the rolls and/or passes are changed by simply rotating the turrets which will automatically remove the old set of rolls from their rolling position and insert the new set therein.
  • the guides for the new rolls can be preassemble-d on the turrets so that once the rolls are brought to the rolling position extensive guide manipulation will not be necessary.
  • One of the turrets in the preferred form of the present invention, is adjustable transversely and vertically rela tive to the other so that the passes of the rolls can be brought to their proper cooperative positions.
  • each turret is provided with a downward projection for each of its rolls, in which either one or the other of these projections contact a restricting surface that prevents rotation of the turrets during the operation of the mill.
  • Means are provided for raising the turrets so as to free the contacting projections and allow the turrets to be rotated, after which they can be lowered and the other projections will come into the restrictive positions. The raising and lowering of the turrets will also automatically disengage and engage the ends of the rolls from the driving spindles.
  • FIGURE 1 is a plan view of a vertical mill incorporating the features of the present invention
  • FIGURE 2 is a sectional view taken on lines IIII of FIGURE 1,
  • FIGURE 3 is a sectional view taken on lines III-III of FIGURE 2,
  • FIGURE 4 is a sectional view taken on lines IVIV of FIGURE 2,
  • FIGURE 5 is a sectional view taken on lines VV of FIGURE 2, and
  • FIGURE 6 is a sectional view taken on lines VIVI of FIGURE 2.
  • FIGURES l, 4 and 5 there is provided two pairs of horizontally spaced apart upright frames 11 and 12 to which are secured at their tops and bottoms two pairs of horizontally extending beams 13 and 14, the beam being best shown in FIGURE 4.
  • the beams 13 serve to support upper turret housings 15 and 16, these beams having recesses 17 that form supporting surfaces for the turret housings 15 and 16 and a guiding surface for the housing 15.
  • the lower beams 14 are provided with projections 18 which support lower turret housings 21 and 22 and in addition guide the lower turret housing 21.
  • the pairs of upper and lower turret housings are vertically spaced away from each other, and each is provided with opposed bearing-lined complementary openings 23, these openings being best shown in FIGURES 2 and 5.
  • each housing there is rotatably received vertically arranged turrets 24 and 25, this construction also :being best shown in FIGURE 2.
  • Each of these turrets has extending from its opposite sides, spaced 180 apart, horizontal roll supporting wings 26 and 27, FIGURE 6 showing this construction in detail as to the turret 25.
  • the wings 27 rotatably carry cooperating metal reducing rolls 28 and 29, whereas, with respect to the wings 26, it will be noted that the rolls which are adapted to be carried thereby have been omitted for the purpose of illustration.
  • the wings 26 and 27 are provided with slotted studs 31 over which pass openings formed in chocks 32 of the rolls, the chocks being secured to the wings 27 by tapered keys 33 that are inserted in the slots of the studs 31.
  • the keys can be seen in referring to FIGURES 2 and 4.
  • the rolls 28 and 29 being formed with only one pass can be made quite short in length and small in diameter.
  • roll guides 34 are secured to the wings 26 and 27 by tapered keys 35.
  • At the bottom of each of the wings 26 and 27 a pair of downwardly extending projections 36 are provided.
  • the projections 36 of the wings 27 carrying the rolls 28 and 29 engage upward projections 37 formed on the inner sides of the lower turret housings 21 and 22. In this way the turrets 24 and 25 are prevented from rotating during the engagement of the projections, but yet, the turret 24 is permitted to move freely transversely toward and away from the turret 25.
  • the turrets 24 and 25 are raised through the agency of individual piston cylinder assemblies 38 and 39, respectively, the cylinders of which are secured to the upper 4 turret housings 15 and 16, this construction being best shown in FIGURES 2, 3 and 4.
  • the elongated rods 41 of the piston cylinder assemblies, 38 and 39 are secured to the lower ends of non-rotatable sleeves 40 which are spaced intermediate the extreme lower end of the rods and the lower ends of the turrets.
  • the sleeves 40 carry the weight of the turrets and for which reason their upper ends are flanged, the upper surfaces of which carry bearings and the lower, surfaces rest upon the lower turret housings 21 and 22.
  • the sleeves 40 and turrets will be raised a distance suflicient to enable the projections 36 of the wings 26 or 27 to clear the projections 37 formed on the lower. turret housings 21 and 22. It will also be noted that the lifting movement will automatically raise the end of the rolls 28 and 29 out of the couplings, to be referred to later. The lowering of the turrets will cause the rolls and couplings to automatically engage each other, the rolls, if necessary, having been turned to the proper angular positions relative to V couplings to assure this result.
  • a racthet ring 45 which is rotatably received in the top of the upper turret housings 15 and 16. From the centers of the ratchet rings 45, sleeves 46 extend downwardly, the lower portions of which are provided with flat driving surfaces against which engage complementary surfaces formed in openings 47 of flanges 48. As shown in FIGURE 2 the flanges 48 are secured to the top of the turrets 24 and 25 and through which pass the rods 41 of the piston cylinder assembly 38.
  • piston cylinder assemblies 55 are arranged on the drive side of the mill,
  • the rods 56 of the piston cylinder assemblies 55 are extended and their ends engage one of the vertical sides of the projections 53 of the turret housing 21 whereby the turret is urged against the screws of the lower worm-wheel-screw set 50.
  • the turret 24, as previously noted, in addition to being moved transversely relative to the turret 25 is also 'adjustable vertically relative thereto.
  • the extended rod 41 o f the piston cylinder assembly 38 is connected at its lower end to a cross link 57, the opposite ends of the cross link being, in turn, pivotally connected to a short link 58 and an adjustable longer link 59.
  • the short link 58 is pivotally secured to the turret housing 21; whereas, the upper end of the longer link passes through an opening formed in the turret housing 21, which end is threaded for receiving a nut 61.
  • the turret 24 and its roll 28 can thus be raised by operation of the piston cylinder assembly 38 to align the pass of the roll 28 relative to the pass of the roll 29.
  • the nut 61 can be tightened up to maintain the turret 24 in the adjusted position.
  • the lower ends of the rolls 28 and 29 are provided with couplings 62, the couplings being drivenly connected to spindles 63 which, in turn, are connected to a drive 64 and thus to a motor 65.
  • a new set of rolls can be mounted on the outer wings 26 of turrets 24 and 25 while the mill rolls 28 and 29 are rolling steel.
  • the guides for the new set of rolls also can be prepositioned, whereby simply by raising and rotating the turrets 24 and 25 the new rolls and guides can be quickly brought into the operating position.
  • This condition not only greatly reduces the roll changing time in comparison with present-day mills, but of equal importance it greatly simplifies the rolling schedule and, as a result, quick delivery of small tonnage orders can be made.
  • the actual roll changing of the mill is not dependent upon the employment of a crane, so that the services of the crane can be made available for other important mill maintenance operations during this period. As a result, the total nonproductive time of the entire plant is reduced, in addition to the substantial reduction in downtime for changing the rolls of the vertical mill itself.
  • a rolling mill comprising:
  • said members being so arranged with respect to each other and the rolls of one member with respect to the rolls of the other member that the roll can be brought selectively into and out of a single cooperative operating position on the rotation of the members
