Definitions

  • ABSTRACT This invention relates to a process and device for cooling hot-rolled wire rods for producing wire rods having a uniform quality and excellent mechanical properties by greatly reducing the dfference between the cooling rates in the central region and marginal regions of circular coiled wire rods which are conveyed continuously in a horizontal direction under such conditions that the centers of the wire rod coils are continuously shifted relatively at a fixed pitch.
  • the above mentioned wire rods in the form of eccentrically overlapped rings mounted on the conveyer are overlapped closely in both marginal regions but coarsely in the central region. Accordingly, the rings are cooled with air slowly in both marginal regions of said wire rods and more rapidly in the central region. Therefore, the produced wire rods have fluctuating mechanical properties and are reduced in quality.
  • a main object of the present invention is to provide an improved cooling process and device so that wire rods may be uniformly cooled in the respective regions by simultaneously using a process of cooling both marginal regions of the eccentrically overlapped rings of the wire rods by blowing cooling fluid laterally inward thereacross from any of diagonally above, sidewise and diagonally below with a fluid at a flow velocity of not less than 30 m./sec. (which shall be called edge aircooling hereinafter). Further the hot-rolled wire rods are cooled from 900C. to 550C. with a fluid at a flow velocity of not less than m./sec.
  • the mechanical properties of said wire rods are influenced in a manner to obtain wire rods having an improved quality and uniform mechanical properties by eliminating the above mentioned defects.
  • the cooling rates in the central region and both marginal regions of the ring wire rods will not be uniform and, when the flow velocity of the fluid blown generally vertically from either of the upper or lower ducts is not more than 20 m./sec., in the case where a single wire 5.5 mm. in diameter is to be cooled, an average cooling rate of 7/sec. from 900 C. to 550 C., as required for a patenting treatment, will not be obtained.
  • Another object of the present invention is to provide various devices having improved effects in the above mentioned process and device.
  • the uniformity of cooling wire rods is also further improved by cooling said wire rods generally vertically from either above or below and laterally inwardly from any of diagonally above, sidewise and diagonally below while expanding the gaps between the rings by relatively vertically shifting said wire rods in their marginal regions with a vertically moving mechanism.
  • the above described vertically moving mechanism is a mechanism, for example, comprising (1) a plurality of free horizontal rollers set higher than the level of the conveying floor at a spacing smaller than the wire ring diameter of said wire rods on both sides of the conveyer and at a fixed spacing in a direction parallel to the advancing direction of the wire rods, (2) eccentric rollers connected with rotary shafts at a spacing smaller than the wire ring diameter of the wire rods disposed on both sides of a conveyer, rotated by motors through chain wheels and driving chains and provided to be higher than the level of the conveying floor at a fixed spacing or (3) free rollers provided with chains rotating in the reverse direction to that of the conveyer for the wire rings and having a spacing smaller than the wire ring diameter, said rollers being disposed on both sides of the conveyer chain and at a higher level then the conveying floor at a fixed spacing on the above mentioned chains rotating in the reverse direction.
  • a roller conveyer or divided chain (which is called a braking mechanism) can be adapted instead of the conventional endless conveyer chain so that the overlapped regions of said wire rods may be deviated to form gaps between the wire rods and the uniform cooling effect may be improved by the fluid-blow cooling in a vertical from either above or below and laterally inwardly from any of diagonally above, sidewise and diagonally below.
  • roller conveyer comprises cylindrical rollers and rollers having a larger diameter at their ends than in the middle. Such rollers are properly combined and the rotating velocities of the respective rollers are freely adjustable in response to the chemical composition of the wire rods. Further, in the above mentioned divided chain, a plurality of rows of respectively independently rotating chains are provided parallelism with the advancing direction of said wire rods and at a spacing smaller than the wire ring diameter of the wire rods and the velocities of the respective chains are adjustable.
  • the effect of unifonnly cooling wire rods is improved by fluid-blow cooling in a vertical direction from either above or below and laterally inwardly from any of diagonally above, sidewise and diagonally below while snaking said wire rods by a snaking mechanism wherein, for example, a plurality of vertical rollers are provided at a higher level then the conveying floor, at a spacing smaller than the wire ring diameter of said wire rods, in zigzag relationship on both sides of the conveyer and at a fixed spacing parallel to the advancing direction of the wire rods so that the marginal regions of the wire rods are shifted relatively in a horizontal direction.
  • the effect of uniformly cooling wire rods can be further improved by a fluid-blow cooling from below and from diagonally above by snaking said wire rods while moving them vertically by combining the snaking mechanism with the above described vertically moving mechanism.
  • Such respective mechanisms mentioned above as the vertically moving mechanism, braking mechanism and snaking mechanism may be used not only individually but also in combination to further improve the uniformly cooling effect. That is to say, for example, a combination of the vertically moving mechanism with either of the braking mechanism and snaking mechanism and a combination of the braking mechanism with the snaking mechanism are considered. Further, all of these three mechanisms may be combined.
  • any mechanism for deviating the wire rods may be used.

  • hot-rolled wire rods are cooled with a known water-cooling device, are layed on a horizontal conveyer 2 with a laying cone 1, in the form of eccentrically overlapped wire rings 3 having a pitch of 38 mm. at the center of the conveyer and a wire ring diameter of 1,045 mm. and are conveyed at a fixed pitch in the direction indicated by the arrow on the horizontal conveyer 2.
  • Example 1 (See FIGS. 1 and 2).
  • An opening 22 having removable guide plates 21 at any spacing which could blow air laterally toward the upper surface of each side part of the eccentrically overlapped wire rings conveyed with a conveyer chain was provided in the upper part of a side wall provided along each side of the conveyer. Air was blown at a flow velocity of 65 m./sec. laterally inwardly onto both marginal regions of the wire rods through said openings 22 and further air was blown upwardly at a flow velocity of 35 m./sec. through ducts below the conveyer. In this case, the difi'erence between the average cooling rates from 900 C. to 550 C. in the marginal regions and the central region of the wire rods was 1.5 C. It was 5.2 C.
  • Example 2 (See FIGS. 1 and 2).
  • Vertical rollers 4 and 4 were arranged from the inlet of a cooling zone so as to be higher than the level of the conveying floor and in zigzag relationship 'at a spacing A of 1,015 mm. laterally of the above mentioned conveyer and at a spacing B or B of 4 m. longitudinally of the conveyer along both sides of the conveyer.
  • the marginal regions of the eccentrically overlapped wire rings were pushed inwardly about 30 mm. and said wire rods were conveyed while being snaked on the conveyer 2.
  • the above mentioned vertical rollers 4 and 4' were rotatably supported with respective roller shafts 6 passed through a bottom plate 5 of the conveyer.
  • the above mentioned vertical rollers were adjustable to facilitate the proper cooling of wire rods of various chemical compositions.
  • the overlapped marginal regions of the wire rings of the wire rods were deviated relatively in the horizontal direction.
  • the difference between the average cooling rates from 900 C. to 550 C. in the central region and the marginal regions of the wire rods was l.6 C./sec. It was 5.2 C./sec. in a conventional process wherein the wire rods were cooled by an up-draft blowing at a flow velocity of 35 m./sec. through the ducts 20 on the lower surface.
  • Opposed horizontal rollers 10 and 10 were provided at a higher level than the conveying floor from the inlet of a cooling zone, at a spacing C of 1,015 mm. laterally the conveyor and at a spacing D or D of 500 mm. longitudinally of said conveyer on both sides of the latter. Wire rods were conveyed while the marginal regions of the rings were vertically shifted.
  • rollers 10 and 10' were rotatably supported on respective roller shafts 12 secured to levers 11 and 11 provided on both sides of them.
  • the above mentioned levers were connected with a joint 17 through a supporting shaft passing through bearings 13 and 14 and a lever 16 connected with said supporting shaft.
  • Said joint was connected with a cylinder 18 through a connecting rod 23 so as to be movable forward and rearward.
  • the above mentioned levers 11 and 11 and lever 16 were made to keep a fixed angle a so that it might be possible to adjust the level of the horizontal rollers with the advancing and retreating motions of the cylinder 18.
  • the marginal regions of the wire rings were moved vertically, the overlapped marginal regions of the wire rings produced gaps and, as a result, the difference between the average cooling rates from 900 C. to 550 C. in the central region and the marginal regions of the wire rods was 10 C./sec. It was 5.2 C./sec. in a conventional process wherein the wire rods were cooled by an up-draft blowing at a flow velocity of 35 m./sec. through the ducts on the lower surface.
  • Example 4 (See FIGS. 4 and 5).
  • Eccentric rollers 24 and 24 were set as opposed to each other at a higher level than the conveying floor, at a lateral spacing A of 1,015 mm. and a longitudinal spacing D of 500 mm. on both sides of the conveyer.
  • the above mentioned eccentric rollers had a diameter of mm. and an eccentricity of 20 to 30 mm. and their roller shafts 27 were driven by driving motors 26 and 26' through driving chains 25 and 25. It was found to be desirable to synchronize the rotating velocity of the eccentric roller with the moving velocity of the conveyer chain 7. In this example, a roller rotating velocity of rpm. was synchronized with a conveyer velocity of 0.6 m./sec.
  • Example 5 (See FIGS. 6 and 7).
  • Clain links 28 and 28 moving in the direction reverse to that of a chain conveyer for conveying wire rods were provided on both sides of the conveyer at a lateral spacing A of 1,015 mm. and free rollers 29 and 29 were rotatably fitted at a higher level than the conveying floor at a spacing of 1 m. in the upper part of the links of said chain conveyer (the top surface of the roller being about 40 mm. above the upper surface of the rail) so as to move the marginal portions of the ring vertically up and down.
  • the velocity of the above mentioned conveyers 28 and 28' provided with the rollers was adjustable in response to the chemical composition of the wire rod.
  • the chain links provided with the rollers were connected with a motor 32 through a chain wheel 30 and driving chain 31.
  • the marginal regions of the wire rings were lifted by the chain links provided with the rollers of the above mentioned mechanism to make gaps among the overlapped parts and were cooled by laterally inwardly directed edge air-cooling and vertically directed aircooling from below.
  • the difference between the cooling rates in the marginal region and central region of the wire rods was the same as in the case of using the horizontal rollers 10 and 10' in Example 3.
  • the effects could be increased by fitting vertical rollers to the conveyer provided with rollers.
  • a cooling chain conveyer located in a cooling zone from 900 C. to 550 C. was equipped with a divided chain system. That is to say, chains 7, 7 and 7 driven by respective separate chain wheels 33, 34 and 35 were provided as short links at a spacing smaller than the wire ring diameter of the wire rod and the velocity of each chain link was variable, for example, 0.6 m./sec. for the outside chains 7 and 7 and 0.9 m./sec. for the inside chains 7' and 7". Then the overlapped wire rings of the wire rods were shifted relatively forwardly and rearwardly to make gaps.
  • Air was blown laterally inwardly onto the marginal regions of said wire rods at a flow velocity of 60 m./sec. through the opening 22 and also vertically at 35 m./sec. through the ducts 20 below the conveyer.
  • the difference between the average cooling rates in the marginal regions and central region of the wire rods was the same as in the case of using the horizontal rollers 10 and 10 described in Example 3.
  • outside conveyers 7 and 7" or the inside conveyers 7' and 7 were described to be of the same velocity. But, as required, the respective conveyers 7, 7 7" and 7" could be moved at respectively different velocities and, when the above described vertical rollers in this example were simultaneously used, the effects were even better.
  • Example 7 (See FIGS. 9 and 9a).
  • a cooling conveyer located in a cooling zone from 900 C, to 550 C. was equipped with a roller conveyer system.
  • conveyer rollers 36 driven by such driving mechanism as, for example, bevel gears 37 and 37' were provided at a suitable spacing and rollers which were larger in diameter at both ends or one end than in the middle (to be, for example, 60 mm. in the middle and 120 mm. at the ends) were arranged at intervals of several rollers so as to move the marginal regions of the rings vertically up and down. Further, the reduction ratio of the bevel gears was set so that the speed might be changed at intervals of several rollers.
  • the driving mechanism not only the bevel gears but also motor rollers connected directly with respective rollers or a chain drive can be properly used.
  • Example 8 (See FIGS. 2 and 3).
  • the vertical rollers 4 and 4' described in Example 2 were arranged in contact with the center line of the respective horizontal rollers described in Example 3 on both sides of a conveyer. Air was blown laterally inwardly onto the marginal regions of the wire rods at a flow velocity of 50 m./sec. through the openings 22 and also vertically upwardly at a flow velocity of 35 m./sec. through the ducts 20 below the conveyer. As a result, the difference between the average cooling rates from 900 C. to 550 C. in the central region and marginal regions of said wire rods were 0.5 C./sec.
  • the cooling rates in the central region and both marginal regions of the wire rings of said wire rods become so uniform that the quality and mechanical properties of the produced wire rods are vastly improved.
