Definitions

  • the invention relates to a process for the production of rolling stock by continuous casting for long products made of metal, in particular steel, in which a first adjustment of the round casting material to tapping dimensions of a longitudinal rolling mill or to forging dimensions takes place through the casting process.
  • pre-rolled material has been produced from ingots produced in the cast iron in a square or rectangular cross-section.
  • materials produced in the stationary casting are rolled into primary materials in the block rolling mill.
  • Continuously cast billets with an edge length of approx. 130 mm are cast in a soothing silicon-manganese manner with an open pouring jet and used as pre-rolled materials.
  • An example of the use of continuously cast billets is the rolling stock of a wire mill.
  • continuously cast billets are homogenized in the heating furnace and processed into wire in a wire mill (consisting of a multi-stand reducing roll mill).
  • values set the maximum rolling speed in the final stand and the minimum rolling speed in the tapping stand. If the tapping speed is too low of approx. 0.08 m / sec, the rolls will burn.
  • a tap size of 130 ⁇ 130 mm would also be one Stick length of 35 m required, but this is difficult to handle.
  • the invention is therefore based on the object of demonstrating a process for producing rolled starting material by continuous casting for long products made of metal, which is based on higher material qualities (with regard to analysis and quality) and improved surface with high economy.
  • final or finished product dimensions can be produced from continuous casting, which previously required block casting with the same quality. It can also be used directly, which means that less energy is required than previously. Direct use is only possible because the quality of the large casting dimensions means that there is no need for inspection.
  • the cost advantages are less storage of spare parts and exchange parts, increased operating times (reduction of set-up times).
  • the invention therefore leads to a standard system of greater economy.
  • the advantages mentioned above affect the continuous caster itself. However, there are still advantages in the "forward" direction, since smaller finished products (cross-sections) can be produced from large input cross-sections with fewer rolling passes (roughing stands). Such pre-rolled material for long products can be produced particularly advantageously in large capacity blow molding plants.
  • An improvement of the invention is that the casting material sections are subsequently deformed to the required tapping dimensions of subsequent longitudinal rolling mills in a high-reducing, cross-rolling mill after the continuous casting.
  • the standard cross-section is chosen to be round between a diameter of 175 mm and 600 mm. This measure leads to a high level of casting reliability, to simple regulation and thus to fewer disruptions to the casting operation.
  • the casting material is produced in a horizontal position.
  • the use of horizontally produced casting material is made possible by the compensation of the core porosities that occur in the case of horizontal continuous casting, which are completely eliminated in the highly reducing, cross-working rolling mill.
  • the heat compensation takes place in a passage space which inhibits and / or compensates for the radiation losses.
  • the heat losses are in fact small due to the proposed volume / surface ratio.
  • the method according to the invention is shown schematically in comparison with the prior art in the accompanying drawing.
  • the only figure in the drawing shows the material flow in a process chain for the known and the new process for producing rolled starting material.
  • (1) designates the production of the liquid metal in a blow steel mill and (2) in an electric arc furnace.
  • the liquid metal is further treated in a secondary metallurgical treatment stage (3).
  • the liquid metal produced in this way is now supplied to the rolling mills (6) for long products in the highest qualities and grades via ingot casting (4) and several ingot rolling stages (5).
  • Such long products consist of profile bars, profile beams, wire and rails. So far, the latter have only been rolled from square stock.
  • the method according to the invention for producing high-quality and high-quality rolled starting material with cost savings compared to the line (4, 5) and (6) is carried out either in the horizontal continuous casting installation (8) or in the curved continuous casting apparatus (9) by casting round cross sections made from aluminum-calmed qualities.
  • the round cross sections produced in this way with a volume / surface ratio of at least 40: 1 to 150: 1 and a uniform cross section between a diameter of 175 mm to 600 mm round are then passed through the passage space (10) which inhibits and / or compensates for radiation losses and in Highly reducing, cross-working rolling mill (11) reduced to the desired tapping cross section or introduced directly into the rolling mill (6).
