Definitions

  • This invention relates generally to the manufacture of fine wire or like products from metal rod, and particularly to a fluid cooling and lubricating system for metal rod being rolled down from a continuously cast bar.
  • the method disclosed in the above-identified patent is accomplished by using a continuous casting machine in which molten aluminum-base metal is solidified to obtain a cast metal and a rolling mill to which the cast metal is passed at hot-forming temperature from the casting machine and which has a plurality of roll stands which alternately change the transverse cross-sectional shape of the cast metal.
  • the as-cast grain structure of the cast metal is substantially completely destroyed by deforming the cast metal a substantial number of times to cause an elongation of the cast metal along its axis of elongation by a factor of at least twenty and to cause a substantial movement of the cast metal along a plurality of axes substantially perpendicular to the axis of elongation.
  • the present invention is directed to a novel fluid cooling and lubricating system adapted to be used with the rolling mill used to accomplish the method disclosed in the above-identified patent, as well as with other similar apparatus for rolling other metals such as copper or steel rod.
  • the method and apparatus disclosed herein result in an aluminum rod that, when 'drawn into aluminum wire by use of standard, prior art drawing techniques, will have higher tensile strength and higher electrical conductivity than the same wire would-have when drawn from rod produced by rolling equipment possessing prior art cooling and lubricating systems.
  • the rod may enter a cooling and/or. pickling system upon its exit from the rolling mill.
  • the variation in the exit temperature of the rolled rod caused by the prior art fixed coolant volume capacity adversely affects the quality of the pickling and the physical properties of the rod.
  • the highest rod temperature upper limit on the overall production rate of the rod.
  • the high exit temperature is occasioned by the necessity for rolling the rod at the maximum possible temperature in order to reduce the mechanical power re-.
  • the primary object of this invention to provide a fluid cooling'and lubricating system for a rolling mill that produces metal rod having superior and more consistent metallurgical properties.
  • Another object of this invention is to provide a fluid cooling and lubricating system for a rolling mill wherein variations in the temperature of rod exiting from the mill are substantially eliminated.
  • Another object of this invention is to provide a fluid cooling and lubricating system for a rolling mill wherein the temperature of rod exiting from the mill is substantially reduced in comparison with exit temperatures resulting from prior art systems.
  • Still another object of this invention is to provide a fluid cooling and lubricating system for metal rod being rolled down from a continuously-cast bar including a multiple pressure arrangement wherein high pressure fluid is utilized to cool and descale the rod as well as the hot-forming rolls by spraying, and wherein low pressure fluid is additionally utilized for cooling and lubrication and for rod oxidation control by flooding roll stand entrance and exit rod-guide housings. Such flooding also yields a better rod surface by reducing the friction between the rolls and the rod.
  • a further object of this invention is to achieve a consistent finishing temperature for hot-formed rod exiting from a rolling mill including a fluid cooling and lub-ricating system providing direct and controlled spray cooling of the hot-formed rod through wide-angled spray nozzles having flow control means responsive to the exit temperature of the rod for controlling the volume ofcoolant.
  • Yet another object of this invention is to provide a fluid cooling and lubricating system for a multiple standrolling mill wherein the volume of coolant is progressively increased in each stand from the inlet to the outlet of the mill whereby rod is rolled in the-primary roughing stands at desirable higher temperatures and finished at the lowest possible temperature consistent with power requirements.
  • FIG. 1 is a semi-schematic elevation view of rodmanufacturing apparatus including a continuous casting machine, multiple stand rolling mill and pickling apparatus upon which the fluid cooling and lubricating system of this invention is adapted to be utilized.
  • FIG. 2 is a plan view of a single roll stand of the multiple stand rolling mill shown in FIG. 1, and depicts the piping, nozzles and rod-guide housings used in the multiple pressure cooling and lubricating arrangement of this invention.
  • FIG. 3 is an enlarged generally schematic sectional view taken along line 3-3 of FIG. 2, and depicts the rod supported in a flooded guide housing.
  • FIG. 4 is an enlarged generally schematic sectional view taken along line 4-4 of FIG. 2, and depicts an idle rollerrod support and seal arrangement for the rod inlet to the guide housing.
  • FIG. 5 is a generally schematic fragmentary plan view of two finishing roll stands of the multiple stand rolling mill shown in FIG. 1, and depicts the rod and rolls being sprayed by nozzles having solenoid-operated valves controlled by a photopyrometer which monitors the finishing temperature of the rod.
  • FIG. 1 rod manufacturing apparatus including a continuous casting machine 10, a multiple stand rolling mill 11 and pickling apparatus 12.
  • the continuous casting machine serves as a casting means for solidifying molten metal to provide a cast metal such as a cast bar 13 that is conveyed in substantially that condition in which it solidified from the continuous casting machine 10 to the rolling mill 11.
  • the rolling mill 11 serves as a hot-forming means for hot-forming-the cast bar 13 into a rod 14 of aluminum or another hotformed aluminum-base product in accordance with the method disclosed in the above-identified and commonly assigned U.S. Pat. No. 3,561,105, or a rod of other hot-formed metals such as copper or steel.
  • the continuous casting machine 10 is of conventional casting wheel type similar to that shown in U.S. Pat. No. 3,318,367 and has a casting wheel 15 with a casting groove (not shown) partially closed by an' end less band 16 which is supported against the casting wheel 15 by a plurality of idler wheels 17.
  • the casting wheel 15 and endless band 16 cooperate to provide a mold (not shown) into oneend of which molten metal is poured to solidify and form, and out of the other end of which emits the cast bar 13 in substantially that condition in which it solidified.
  • the rolling mill 11 includes a plurality of roll stands 18 through 29 which are arranged in alternate horizontal and vertical dispositions to hot-form the cast metal by a series of successive deformations.
  • the continuous casting machine 10 and the rolling mill 11 are posishape of the rod 14.
  • Therod 14 is guided to and from a tioned relative to each other so that the cast bar 13 enters the rolling mill 11 substantially immediately after solidification so as to be in substantially that condition in which it solidified and at a hot-forming temperature within the acceptable range of temperatures for hotforming the cast bar 13.
  • the cast bar 13 may be any one of a plurality of lengths determined only by the amount of molten metal available and will extend in the form of a cast bar between the continuous casting machine 10 and the rolling mill 11. It should be thus apparent that the steps of solidifying molten metal to obtain cast metal and of hot-forming the cast metal, as well as the step of pickling (i.e., copper or steel) the hot-formed cast metal in the pickling apparatus 12, are generally being performed simultaneously once the apparatus of FIG. 1 is in operation.
  • the cast metal bar 13 enters the rolling mill 11 through preliminary or roughing stands 18 and 19 and proceeds down its path through a series of finishing stands 20 through 29, out exit point 30 and, if desired, as sometimes is in the case of copper or steel, into the pickling .apparatus 12 downstream from the rolling mill 11.
  • the power requirements for hot-forming, and hence the desired temperature levels are at a maximum in the roughing stands 18 and 19 and thereafter progressively decrease through the finishing stands 2029.
  • FIG. 2 a novel multiple pressure arrangement for'delivering a cooling and lubricating oil solution to one stand of the multiple stand rolling mill 11 of'FIG. 1.
  • the stand includes a frame 31 upon which are suitably mounted hot-forming rolls 32 driven by conventional means (not shown) which will be apparent to those skilled in the art.
  • the rod 14 is adapted to be passed between the rolls 32 which deform the cast metal in the case of roll stand 18, and thereafter change the cross-sectional the rolls 32 by entrance and exit rod-guide housings 33 and 34, respectively.
  • the rod-guide housings 33 and 34 are suitably secu'redto the frame 31 by means of brackets 35 and 36, respectively.
  • the guide housing 33 includes an outlet end 37 in which are suitably jour' nalled upper and lower idler roller guides 38 which support the rod 14 through the housing 33.
  • the housing 33 also includes an inlet end 39in which are alsosuitably journalled idler roller guides 40 which provide a similar function as the roller guides 38.
  • the roller guides 40 may be so arranged as to provide a partial seal around the rod 14 at the inlet end 39 of the guide housing 33. Similar roller guides and seals (not shown) may be provided with the exit rod-guide housing 34. It should be understood, however, that the specific structure shown in FIGS. 3 and 4 is for illustrative purposes only and is not intended to limit the general concept of the invention. In fact, any method of rod guiding, supporting, and sealing may be utilized within the scope of the appended claims.
  • Low pressure fluid coolant C such as soluble oil
  • piping 41 from a source (not shown) into the rod-guide housing 33 at a point near the rod inlet end 39.
  • the rod-guide housing 33 fills or floods in the same manner as a sink with a drain too small to remove the fluid as fast as it enters.
  • the fluid coolant C therefore surrounds the rod 14 as shown in FIG. 3 to cool both housing 33 and the rod 14.
  • Exiting fluid may be directed out of the rod outlet end 37 of the housing 33 towards the rolls 32 to reduce the friction between the rod and the rolls and also to lubricate and cool the rolls.
  • the partial seal arrangement effected by the idler guide rollers 40 at the inlet end 39 of the housing 33 assures that the major portion of the overflowing coolant C will be directed out of the outlet end 37 towards the forming rolls 32. Both the guide housing 33 and the forming rolls 32 are protected by, the cooling and lubricating action of the fluid coolant C.
  • the reduced friction between the rod and the rolls meaning less friction than in prior art rolling mills, yields a rod having better rod surface quality than prior art rod.
  • Low pressure fluid coolant is also directed through piping 42 to the rod-guide exit housing 34 and delivered near the point where the rod 14 exits therefrom. It should be apparent, therefore, that the coolant C will be directed through the housing 34 in counterflow relationship to the movement of the rod 14 therethrough. The coolant C floods the exit housing 34 and then spills out to flood the rolls 32 in a manner similar to the flooding of the entrance housing 33.
  • the rod stand illustrated in FIG. 2 also includes spray blocks 43 suitably secured to the frame 31.
  • Each of the spray blocks 43 has two adjustable spray nozzles 44 and 45.
  • Fluid coolant from a source (not shown) . is conducted through piping 46 to the spray blocks 43 where it is emitted by the spray nozzles 44 and 45.
  • Low pressure sprays (albeit of higher pressure than found in pipes 41, 42 and in guides 33, 34) emitted by the spray nozzles 44 are directed against the rolls 32 for the purpose of cooling and lubricating the rolls 32 as well as for removing surface scale, picked up by the rolls from the rod 14 during working, which scale tends to be deposited upon and to build up uponthe surface of the rolls 32. This deposit is detrimental to the surface quality of the subsequent rod produced as well as being detrimental to the'u'seful service of the rolls 32.
  • High pressure sprays emitted from the nozzles are directed against the junction of the rolls 32 and the rod 14 for the purpose of removing surface scalefrom the rod 14 as well as in assisting in thec ooling of the rod 14.
  • the nozzles 44 and 45 may be made adjustableas to angle of spray and flow rate in accordance with known, prior art nozzle technology, so as to provide flexibility in both spray pattern and volume for both the roll 44 and rod 45 sprays.
  • wire drawn from rod which has been produced in accordance with our invention has a higher average tensile strength than vdoes prior art wire.
  • Our wire also exhibits a greater range of tensile strengths in computing one and two standard deviations from the average tensile strength than does prior art wire.
  • the conductivity in priorart wire drawn from EC rod containing 0.24% Fe is 61.0 percent IACS (International Annealed Copper Standard), but using our invention, the average conductivity of the wire has been found tobe 61.9 percent IACS. This is significant when you compare it to pure aluminum which is only :64.0 percent IACS.
  • the multiple pressure cooling and lubricating system illustrated in FIGS. 2-4 provides low pressure fluid for cooling the rod 14 and lubricating the rolls 32 by the flooding of and subsequent spill-over from the guide housings 33, 34 while simultaneously providing multiple, relatively high pressure flu d sprays for spraying the rolls 32 and rod 14 to achieve descaling and additional cooling, all of said sprays helping to reduce rod oxidation.
  • the above-described multiple pressure system is specifically disclosed herein as being 'applied to only one of the roll stands of the multiple stand mill 11 illustrated in FIG. 1, it should be readily apparent that the system in actual practice may be applied to any number or all of the stands in accordance with the particular cooling and lubricating requirements dictated by the metal being formed and the specific design of the rolling equipment.
  • FIG. 5 there is illustrated apparatus for direct and controlled cooling of the rod 14 which facilitates the production of rod with the lowest possible finishing temperature, while at the same time substantially eliminating variation in the finishing temperature so as to obtain rod with consistent metallurgical properties along its length.
  • FIG. 5 illustrates the direct and controlled cooling apparatus applied only to the last two finishing roll stands 28 and 29, it is to be understood that the system could apply to all the roll stands or only to all the finishing roll stands 20-29 inclusive.
  • the primary roughing stands in the latter case, could be provided with the multiple pressure cooling and lubricating system shown in FIG. 2, for instance.
  • the rod 14 is rolled in the mill 11 at the maximum possible temperatures in order to reduce the mechanical power requirements of the mill.
  • these divergent temperature criteria are accommodated by rolling the rod 14 in the primary roughing stands 18 and 19 at the maximum possible temperatures and thereafter, as the power requirements progressively decrease, rolling the rod 14 at progressively lower temperatures through the finishing stands 20-29 so that the rod 14 exits from the mill 11 at the lowest desired temperature which from a metallurgical point of view for copper, for example, may be between 700 and 800 F.
  • This is accomplished by progressively increasing the volume of cooling fluid applied directly to the rod 14 at each roll stand as the rod 14 moves through the mill 11.
  • the volume of cooling fluid is at a minimum at stand 18 and increases progressively to a maximum at stand 29.
  • the direct and controlled cooling of the rod 14 may be achieved by providing each of the finishing roll stands 20-29 with primary and secondary nozzle blocks 48 and 47, respectively.
  • the secondary nozzle blocks 47 include wide-angled spray nozzles 49 which direct a wide-angled spray of coolant fluid against the hotforming rolls 32.
  • the primary nozzle blocks 48 also include wide-angled spray nozzles 50 which direct a wide-angled spray of coolant fluid against the hotforming rolls 32.
  • the primary nozzle blocks 48 also include wide-angled spray nozzles 51 which direct a high pressure wide-angled spray of coolant fluid directly on the rod 14.
  • the pressure of the fluid coolant conducted to the nozzle blocks 48 through piping 52 may be monitored by pressure sensing means such as pressure gauges 53.
  • Flow control means such as valves 54 in'the piping 52 may be adjusted to control the volume of coolant delivered to each of the nozzle blocks 48.

  • the apparatus illustrated in FIG. includes a temperature sensing means such as photopyrometer 55 which permits a constant monitoring of the temperature of the rod 14 as it exits from the mill 11. Temperature sensing means 55 is electrically connected, as shown schematically by the dotted lines 56 in FIG. 5, to a valve actuating means such as electromagnetic solenoid actuators 57 which, when commanded to do so by controllers 90, operate the flow control means 54 and thus control the flow of coolant into the nozzle blocks 48.
