Definitions

  • the invention relates to a method for producing a metallic product in which in a continuous casting liquid metal as a slab from a mold vertically downward in a conveying direction, guided along a strand guide and is deflected in the horizontal, the slab behind the continuous casting in a Oven is heated.
  • the invention has for its object to provide a generic method that allows a further reduction of surface cracks and thus improving the surface quality. In this case, a very fine and homogeneous structure in the material should be achieved.
  • the slab surface is preferably cooled in the above step a) and step c) to a temperature below the Ac1 temperature. Accordingly, it is preferably provided that the slab surface in the above step b) and step d) is heated to a temperature above the Ac3 temperature.
  • the last intensive cooling of the slab is carried out according to a possible embodiment of the invention, as soon as the slab is diverted into the horizontal.
  • the invention is based on a multiple near-surface structural transformation in the continuous casting, in order to improve the surface quality of the slab.
  • a possible embodiment of the method may be such that a first pass through the austenite to ferrite transition to austenite in the surface area of the slab is accomplished by intensive cooling at the top of the continuous run of the continuous casting line, followed by reheating of the near-surface area of the slab by normal or weak cooling in the central region of the strand guide.
  • a second pass through the austenite to ferrite transition to austenite can be done before the bending driver by re-cooling and then rewarming.
  • a third or second pass through the austenite to ferrite transition to austenite may occur before or after the straightening driver.
  • the slab after leaving the mold within the strand guide of the continuous casting plant or after the shears or before entering the tunnel kiln or furnace, the slab is to undergo a multi-stage heat treatment with the aim of setting a fine and homogeneous microstructure in the near-surface edge zone.
  • the already solidified strand shell usually has an austenitic, inhomogeneous solidification structure, depending on the steel composition.
  • the near-surface edge zone of the steel strand is cooled below the mold to a temperature below the Ac1 point, so that in the surface-boundary layers a first transformation of austenite into ferrite takes place.
  • a back transformation of the ferrite into austenite takes place. Both transformation processes are associated with a refinement of the structure.
  • inhomogeneities partial coarseness
  • This "inheriting" of the structural inhomogeneities can be eliminated by repeated, ie two or more stages through the transformation austenite - ferrite - austenite, so that in the end a fine, homogeneous austenitic structure is present.
  • the two-stage transformation of austenite-ferrite-austenite-ferrite-austenite is in particular realized by intensive cooling below the mold in the upper part of the strand guide of the continuous casting plant (austenite close to surface converts to ferrite) and by rewarming of the near-surface boundary layer the core heat of the slab in the middle part of the strand guide (near-surface ferrite converts to austenite).
  • the present invention relates to a process which is carried out in a continuous casting plant for steel. It can be made conventional slabs, thin slabs or medium-thick slabs.
  • a first embodiment of the invention can be seen.
  • the continuous casting plant 1 has a mold 3, under which a strand guide 4 is arranged.
  • the cast slab 2 is deflected from the vertical V in the horizontal H.
  • the slab 2 is thereby conveyed in a conveying direction F.
  • the slab passes into a first heating zone 7, which is arranged in the conveying direction F behind the first cooling zone 6.
  • a reheating of the slab 2 takes place such that in the near-surface edge zone of the slab 2, a structural transformation takes place back from ferrite to austenite.
  • the heating zone 7 there is a normal or weak cooling, so that the said structural transformation can vonstatten.
  • Reference numeral 11 indicates that there are alternative positions for additional chill beams for intensive cooling to accomplish austenite to ferrite conversion.
  • Fig. 2 is shown that the continuous casting 1 is designed as a vertical bending plant, wherein the bending of the slab from the vertical to the horizontal takes place with a solid slab core.
  • a continuous casting 1 is used as a vertical bending plant, wherein the bending is done with liquid slab core.
  • the given reference numerals correspond to those according to Fig. 2 ,
  • the first heating zone 7 is here directly where the slab leaves the vertical V and is bent over.
  • the oven 5 is provided as the second heating zone 9.
  • Fig. 4 is shown schematically how the microstructure changes when the respective transformations of austenite to ferrite and back done.
  • the slab surface 10 is indicated and the microstructure is sketched near the surface of the slab.
  • the respective grain diameters are indicated schematically and set in relation to each other.
  • the last letters in the grain diameters D for three adjacent regions 1, 2 and 3 over the width of the slab indicates the respective status after the corresponding microstructural transformations.
  • the grain size not only becomes smaller, but also uniform.
  • grain diameters are according to the ASTM grain size table of ASTM Nos. -3 to 0.
