Definitions

  • the invention relates to a system for producing hot-rolled steel strip, consisting of a steel strip casting mold with cooled walls, a strip guide device downstream of the mold for diverting the cast strip into the horizontal, a cross-cutting device, a temperature compensation furnace and a rolling mill.
  • Plants for the production of hot-rolled steel strip are already known, the mold being followed by a press roll set to reduce the thickness of the cast steel strip.
  • the object of the invention is to create a system for producing hot-rolled steel strip, in which the investment and space requirements are lower and in which metallurgical errors are avoided and the thermal energy of the steel strip is better preserved for the subsequent rolling process.
  • an arcuate temperature compensation furnace extends over the belt guide device and a straight temperature compensation furnace horizontally adjoining the arcuate temperature compensation furnace is provided with a transverse dividing device.
  • the cast steel strip with a homogeneous structure and uniform temperature can be tapped in the downstream rolling mill with little investment in a smaller hall area while saving thermal energy.
  • At least one pair of press rolls can be arranged between the temperature compensation furnace and the mold, by means of which the cast steel strip is reduced to 6 - 25 mm in thickness.
  • the temperature compensation furnace is advantageously designed as a roller hearth furnace.
  • the guide, drive, bending and straightening rollers located in the furnace can be provided with coolant channels in their interior. It is essential that the bearings, drives and adjusting mechanisms of the rollers are arranged outside the temperature compensation furnace.
  • the first arcuate part of the furnace with its heating and conveying installation is designed as an exchangeable part.
  • a rotating shear is arranged in the temperature compensation furnace, the knife shafts of which can be inserted into the interior of the furnace for cutting through side openings.
  • the rotating shear consists of a movable bearing frame for the knife shafts arranged on the side of the temperature compensation furnace, which is opposite the drive on the other side of the temperature compensation furnace and a stationary bearing frame for counter bearing journals, with sliding doors being arranged in the temperature compensation furnace between the bearing points. Between Couplings are arranged on the counterbearing journals of the knife shafts and the output journals of the scissor drive.
  • the temperature compensation furnace is equipped with one or more lowerable roller table rollers in the entry area of the knife shafts.
  • a flame cutting device can be arranged on each side of the temperature compensation furnace and can be inserted into the furnace for cutting.
  • a carriage which can be moved transversely to the furnace is arranged on each side of the temperature compensation furnace, each of which is provided with a guide arm which can be pivoted on the vertical axis for a cutting torch. Sliding doors are located on the sides of the temperature compensation oven in the swivel range of the guide arms.
  • the flame cutting devices can be guided on a track with a moving component in order to achieve a straight cutting line running perpendicular to the edge of the steel strip.
  • the plant shown in Fig. 1 for the production of steel strip consists of the essential parts steel strip mold 1, pair of rollers or rollers 2, an arc-shaped temperature compensation furnace 3 with guide rollers 10 and drive rollers 11 and a straight horizontal temperature compensation furnace 4 with a cross-section device 7, a rolling mill 5, a cooling section 6 and a winding device 8.
  • the steel strip 9 cast in the steel strip casting mold 1 first passes through the pair of rollers or rollers 2, the thickness being reduced, and then passes directly into an arc-shaped temperature compensation furnace 3. Inside the temperature compensation furnace 3, the steel strip 9 is bent and guide rollers 10 and straightening and driving rollers 11 out.
  • the horizontal temperature compensation furnace 4 directly adjoins the arc-shaped temperature compensation furnace 3. This is provided with an oven roller table 12.
  • the bearings 13 of the guide rollers 10, drive rollers 11 and roller table rollers 12 are arranged outside the oven chambers 14, 15.
  • the drives 16 and adjusting devices 17 of the drive are also located roll 11 outside the furnace chamber 14.
  • the arc-shaped temperature compensation furnace 3 can be extended with the guide rollers 10, drive rollers 11 and heating fittings by suitable conveying means and can be replaced by a change furnace.
  • the horizontal temperature compensation furnace 4 is assigned a rotating cross-section shear, shown in FIGS. 4 and 5, the knife shafts 18, 19 of which are mounted in two stands 20, 21 of a bearing frame 23 which can be displaced on a track 22 transversely to the furnace 4.
  • a pressure medium cylinder 24 is arranged, the piston rod 25 of which can be connected to the storage rack 23 via a head 27 guided on a roller 26 and a hook 28.
  • the knife shafts 18, 19 are located within the furnace chamber 15 only at the time of a cut. After the cut has been made, the bearing frame 23 is removed from the furnace 4 by the hydraulic cylinder 24, as a result of which the knife shafts 18, 19 are pulled laterally out of the furnace 4. Then lateral openings of the temperature compensation furnace are closed by slide 41 and a roller 42 of the furnace roller table 12 lowered to the cut is raised again.
  • the temperature compensation furnace 4 can alternatively be provided with flame cutting devices 49, 50 for dividing the cast steel strip 9.
  • two carriages 43, 44 are arranged opposite each other on both sides of the temperature compensation furnace 4 and can be moved across the furnace.
  • a guide arm 45, 46 is mounted on each carriage 43, 44 on a vertical axis, at the end of which a flame cutting device 49, 50 can be inserted into the furnace chamber 15 through a lateral opening 47, 48.
  • the flame cutting devices 49, 50 are moved to the edges of the steel strip 9. After the beginning of the cutting, the flame cutting devices 49, 50 are guided on a path 51, 52 formed from the carriage movement and a pivoting movement of the guide arm 45, 46, as a result of which a straight cutting line 53 running perpendicular to the steel strip edge is achieved within the furnace chamber 15 during the conveying movement of the steel strip 9 .
