Definitions

  • the invention relates to a method for producing pre-profiles for wire, fine steel and form steel rolling from a cast slab, which is divided in its longitudinal direction.
  • the invention also relates to devices for carrying out the method.
  • the object of the invention is to provide a method with which the production of various preliminary profiles for wire, fine steel and form steel rolling can be carried out in an economical manner, ie with low energy and device expenditure.
  • notches are rolled into a thin slab strand of 40-150 mm in thickness and the pre-profiles lying flat laterally connected by webs are separated in the web area.
  • the invention is based on the knowledge that the modern technology of thin slab casting can form a basis for the economical production of pre-profiles for form steel rolling close to the final dimensions.
  • the rolling notch of the thin slab for the individual pre-profile sections is offset in the longitudinal direction of the strand, jamming of the notch rolling tools is excluded.
  • the slitting of the notched thin slabs can be done economically by wedge splitting in the web area.
  • a separation can be carried out by clearing the webs of the warm slab.
  • conventional separation processes such as flame cutting, plasma cutting or laser cutting can also be used for separating the web. Any remaining remains on the pre-profile sides are then removed.
  • a plant for the production of pre-profiles for wire, fine steel and form steel rolling consists of a device for casting slabs 40 - 150 mm thick, a roller notching device for the broad sides of the thin slabs and a web separating device. Both a sliding mold and a drum casting machine with vertical or horizontal casting direction can be used as the casting device.
  • notched disks with a peripheral region tapering at an acute angle are provided as the roller notch device.
  • Peripheral angles of 10 - 80 ° appear applicable depending on the type of steel, material and temperature, the outer edge of the notched disks is rounded.
  • a notched disk can advantageously be formed from a wedge ring anchored to a shaft or hub and made of highly heat-resistant and wear-resistant material.
  • a plurality of notched disks can be arranged in a rotationally fixed manner on a driven shaft which is mounted on both sides of the strand path in a stand.
  • a plurality of shafts provided with notched disks can be mounted in succession in the direction of the strand running.
  • notched disks are mounted on a crossbar bridging the strand guideway.
  • notched disks are assigned to each other in pairs on each side of the strand.
  • the notched disks can be adjustable transversely to the strand path for adjustment to predetermined pre-profile formats.
  • a web separating device consists of at least one splitting wedge arranged in the strand conveyor path in the web area of the slab. If the bar is thin, broaching knives can be used instead of the riving knife.
  • flame cutting, plasma cutting or laser cutting devices can also be used as web separating devices.
  • the roller notch device is in the vertical Part and the web separator arranged in the horizontal part.
  • the casting speed and the strand cooling result in a zone of complete solidification for each strand thickness. It appears particularly advantageous to arrange the notching device in an area from immediately before to immediately after solidification.
  • a thin slab casting mold 1 is charged with molten steel from a casting tank 2 via a dip tube.
  • the thin slab strand 4 emerging from the mold 1 is guided through support rollers 5 and cooled down to a surface temperature of approximately 1050 ° -1380 ° C.
  • a longitudinal notch device 6 for the thin slab strand 4 is arranged.
  • the thin slab strand 4 is notched from both sides by notch rollers 7 except for a web 8.
  • the notching of the thin slab 4 can, as in Fig. 2, immediately after complete solidification or, as in Fig. 3 before solidification with liquid core 9 i.e. by pressing the strand shells 10 together on narrow tracks 11.
  • the webs 8 formed by the notching process can have a thickness d of 2-30 mm.
  • the longitudinally notched thin slab strand 4 is guided according to FIG. 1 by bending rollers 12 to a driving straightening device 13 and, after a cropping cut, passes through a pair of scissors 14 into the region of a longitudinal dividing device 15, in which 8 individual preliminary profiles 4 ′ are formed by separating the webs. If, after this web separation, 4 'web remains on the preliminary profiles occur, these can be eliminated by a smoothing device 16.
  • the pre-profile strands 4 ' can be temporarily stored in a temperature compensation furnace 17 and adjusted to the rolling temperature.
  • a descaling device 18 and a rolling mill 19 are provided behind the temperature compensation furnace 17.
  • a longitudinal notch device 6 can be designed in different ways.
  • FIGS. 4 and 5 several notch rollers 7 are fastened together on an upper or lower notch roller shaft 20, which are driven.
  • the distance a between the notch rollers 7 on the notch roller shafts 20 determines the dimension of the pre-profiles 4 ′ produced.
  • 4 shows the notch marks 11 generated on the conveyed slab strand 4 by the notch rollers 7.
  • FIG. 6 shows a roller notch device with a staggered arrangement of a plurality of notch roller shafts 21, 22, each with a notch roller 23, 24.
  • the notch roller shafts are cantilevered on side frames 25, 26, with an axial adjustment in the direction of arrows 27 being provided to change the spacing of the track notches 11 can be.
  • the notch roller shafts are advantageously driven.
  • roller notch device In the roller notch device shown in FIG. 7, two frame parts 28, 29 are clamped by pressure medium cylinders 30, the distance being determined by spacers 31.
  • Bearing blocks are located on the inside of the frame parts 28, 29 32, 33 in which a notch roller 34, 35 is mounted.
  • the bearing blocks 32, 33 on the frame parts 28, 29 are received in guides and adjustable by means of spindles 36.
  • the notch rollers 34, 35 are without a drive, ie the notch rollers 34, 35 roll on the conveyed strand 4 and notch it.
  • FIG. 8 shows the slitting of a notched thin slab 4 by means of the slitting device 15.
  • This consists of a number of riving knives 37 or broaching knives 38 arranged in the web area of the slab being conveyed.
  • flame cutting devices, plasma cutting devices or laser cutting devices can alternatively be used for slitting.
  • all wire and fine steel profiles 40b can be produced from the billet profile 40 via an intermediate oval 40a.
  • Sheet wall sections 41b can be produced from a flat section 41 via section 41a.
  • a thicker flat profile 42 can be rolled out via the intermediate profile 42a to form U-profiles 42b.
  • the plate 42, 43 can be rolled out via the intermediate profile 43a into double T-beams 43b.
  • Rails 44b can be rolled from a flat billet 44 via the known intermediate profile 44a.
  • the relevant specialist recognizes that, in addition to the finished profiles shown, a wide range of rolling shapes and dimensions can be produced from the various preliminary profiles.
