Definitions

  • the invention relates to a method and a device for the production of hot-rolled steel strips etc. from continuously cast materials in continuously successive work steps, wherein the continuously cast material is cut to a certain length after solidification, brought to rolling temperature in a compensating furnace and introduced into a finishing mill for rolling becomes.
  • the object of the invention is a further substantial improvement in terms of process and device, in particular the measures mentioned last for the production of hot-rolled steel strips etc.
  • the object is achieved in that the continuously cast starting material is fed after the heating to a multi-stand, reversible finishing mill with a coil box connected to it.
  • an intermediate stand cooling which is regulated over the length and width of the strip in accordance with the temperature profile.
  • a constant rolling temperature is set by the intermediate stand cooling, whereby uniform, improved material properties are achieved over the entire length of the strip.
  • the object of the invention is achieved by a single-strand or multi-strand caster with a downstream equalizing furnace and an intermediate cutting machine, and with a reversible finishing roller train connected to the equalizing furnace with a coil box connected to it.
  • the coil box can also be designed as a winding furnace. After leaving the last roll stand, the respective strand is wound up in the coil box. In this way, it is very advantageous to save on the length of the hall and, above all, the temperature loss for the end of the intermediate belt or end of the intermediate strand can be kept very low.
  • the device shown in the drawing is a continuous casting installation consisting of two casting machines (1 and 2). Each casting machine is followed by a compensating furnace (3) or (4), to which the strands (5) or (6) are fed directly. Cutting machines (7, 8) for cutting the strands (5, 6) to a predetermined length are arranged between the casting machines (1, 2).
  • This finishing mill (10) is advantageously designed with four stands, ie it has four rolling mills (F1, F2, F3, F4) arranged one after the other at a distance.
  • Devices (11, 12) for descaling or cooling the rolling strands are arranged between the rolling mills (F1, F2) and (F3).
  • a further descaling device (13) is connected to the finish rolling mill (10), followed by a coil box (14) (shown in a schematic side view rotated from the drawing plane by 90 degrees).
  • the rolling mills (F1, F2, F3, F4) of the finishing mill (10) are connected to the drive motors (19, 20, 21, 22) via comb rolling gears (15, 16, 17, 18). While between the worm gear (18) and Drive motor (22) a normal gear (23) is arranged, very special gearboxes (24) and (25) are provided between the comb roller gears (16) and (17) and the drive motors (20) and (21).
  • pre-strips or strands (5, 6) with a thickness of over 50 mm, preferably of 65 mm, are produced in the casting machines (1, 2).
  • the strand (5) or (6) is cut off by the cutting machine (7) or (8) and in the compensating furnace (3) or (4) to a temperature of 1100 degrees C to 1130 degrees C brought or heated.
  • the strand (5) is brought directly onto the roller table (9) directly (while the reel with driver (30) required for later winding of the finished rolled strip remains inoperative) and from there the rolling mill or the reversible finishing mill (10) fed, while the strand (6) coming from the equalization furnace (4) is transported in the direction of the arrow (27) onto the feed roller table (9) with the aid of an encapsulated transverse ferry (26) and with the aid of a transverse displacement device (not shown in the drawing), which at the same time also as Outfeed roller table serves.
  • the strand (6) is then unencapsulated and fed directly to the finishing mill (10) without the use of a buffer or holding furnace.
  • the feeding of the strands (5) and (6) from the equalizing furnaces (3) and (4) into the finishing mill (10) is very advantageous alternately and continuously.
  • the higher pre-strip thickness or thickness of the strands (5, 6) very advantageously reduces the temperature loss or the necessary temperature increase in the finishing mill (10).
  • the rolling mill (F1) On the rolling mill (F1), for example, no pass acceptance is carried out during the first pass through the respective strand.
  • the rolling mill (F1) therefore only takes on the transport function for the strip or strand.
  • descaling of the rolled strands takes place in the devices (11, 12).
  • the intermediate thickness of the strands must be chosen in such a way that the strands are easily coiled in the coil box (14) after descaling in the descaling device (13) without problems can.
  • the winding speed of the strands in the coil box (14) is relatively low at approximately 1.6 m / s at the head and 2.8 m / s (depending on the strip thickness) at the end.
  • the drives of the rolling mills (F2) and (F3) - in certain cases also of (F1) - are very advantageously equipped with gearboxes (24) and (25) in order to be able to optimally use the drive motors (20, 21) and reduce investment costs.
  • the drives of the rolling mills must be braked, the gear ratios on the rolling mills (F2) and (F3) switched over and the drives accelerated again.
  • the rollers designed as CVC rollers may have to be moved and the mechanical adjustments moved to the new positions.
  • the strand in the coil box (14) is kept warm. Only the outer strand turn cools more in the coil box (10) compared to the other inner turns of the strand.
  • This drop in temperature of about 15 degrees C of the outer strand turn can, however, very easily be caused by a non-uniform increase in speed in the reversing stitch and / or by an increase in the length of the strip - corresponding to the Temperature curve - controlled interframe cooling can be reduced.
  • no manual gearbox is required on the roll stand (F4), since the roll speeds of the rolling mill (F4) for the first pass through the strands and the reversing process are approximately the same.
  • the rolled strip or roll strand from the coil box (14) must, as is known per se, be wound back or unwound in the opposite direction (arrow 28).
  • the rolling strip In order to eliminate the secondary scale, the rolling strip must be descaled in the descaling device (13) before it enters the rolling mill (F4). All rolling mills from (F4) to (F1) are used in the reversing process.
  • the strip which is then rolled in each case is cooled and wound on a reel shown in the drawing with the reference number (30).
  • the exit speed from the finishing mill (10) after the last pass is approx. 8 m / s for a 2 mm thick finishing strip.
  • the reduction in production due to the reversing process can, however, be easily compensated for at any time by correspondingly higher rolling speeds.
  • the object of the invention is not limited to the embodiment shown in the drawing.
  • the finished rolling mill can also be very advantageously designed as a three-stand rolling mill in a corresponding adaptation to the respective single-strand or multi-strand casting plant. It is also very advantageous to be able to swing the belt on the roller table in front of the finishing mill on which, if it is should be necessary for metallurgical reasons, lower pre-strip inlet temperatures.
