Definitions

  • a board is first fully heated to the austenitizing temperature and then transferred in a two-zone furnace.
  • the first zone of the furnace is approximately heated to the austenitizing temperature, while the second zone has a temperature in the range of about 550 ° C to 700 ° C.
  • the area of the board that was in the first zone becomes hard and firm, the area that was in the second zone comparatively softer and more ductile.
  • the board is transported through a heating furnace, then through a cooling and heating section and then to a press quasi-continuous and substantially uninterrupted, wherein the board in the heating furnace to a temperature above the Austenitizing is heated homogeneously.
  • a first region of the board is transported through a furnace adjacent to the heating furnace such that the first region is further maintained at a temperature above the austenitizing temperature without intermediate temperature reduction.
  • a second area of the board is transported outside the furnace and cooled. After transport at the end of the cooling and heating section, the board can be inserted into the press, even if the structural transformations in the second region of the board are not yet completely completed.
  • the board 2 by means of a transport device 7 from the loading station 1 through the heating furnace 3 and the cooling and heating 4 transported to the transfer station 5 quasi-continuous and uninterrupted or substantially uninterrupted before the Board 2 in the press 6, which may have coolable tools is inserted.
  • the transport device 7 is designed as a roller conveyor, so that the board 2 deposited on the rollers of the transport device 7 is moved by the driven rollers in the transport direction R.
  • the second region 14 of the board 2 is cooled continuously during the quasi-continuous transport through the cooling and heating section 4, wherein the cooling takes place with at least two different cooling rates.
  • FIG. 2 the cooling of the second region 14 is shown in a time-temperature conversion diagram, wherein the cooling with the aid of at least two different cooling rates 15, 16 and 17 to a temperature above the Martensitstarttemperatur M S targeted and controlled.
  • the cooling curve 14a is composed of the cooling rates 15, 16 and 17, wherein the in FIG. 1 displayed points indicate the change in the cooling conditions.
  • the Abkühlkurve 14a may not be arbitrarily performed, otherwise the structure proportions of perlite, bainite and martensite are not achieved as desired.
  • a thin board cools very quickly free, when the ambient temperature is below 300 ° C, but preferably at 30 ° C. Typical times are on the order of 15-120 seconds.
  • the second region 14 is heated very quickly, which is in FIG. 3 is shown by the heating curve 12b, wherein the heating temperature should be below the A C1 temperature, but in no case may exceed the A C3 temperature.
  • the temperature heating curve 19, which in FIG. 4 is shown for two different courses, can be guided through the area of Baint formation or through the area of bainite B and then further into the area of ferrite / pearlite formation F, P.
  • the cooling and heating section 4 has at least one rapid heating device which, in relation to the transport direction R, is arranged outside and laterally from the oven 4 in the region of the width section 11 of the transport device 7 arranged outside the oven 4 and optionally in relation to the transport direction R. behind the heat sink is arranged.
  • the rapid heating device may be a radiant heating device with at least one gas burner and / or at least one infrared radiator.
  • the rapid heating device may comprise an inductive heating device and / or a resistive heating. It is understood that the successively arranged hood elements 18 may be formed with means for cooling and subsequent heating according to that of the device with hood elements 18 and the second way process technology can be realized.
