Definitions

  • Hot dip coating of steel strips containing only small amounts of said alloying ingredients is problematic, there are difficulties in the Schmel dive coating of steel sheet with higher alloying proportions difficulties. On the surface of the steel sheet there are liability deficiencies of the coating, and even uncoated areas are formed.
  • DE 695 07 977 T2 discloses a two-stage hot dip coating process of a chromium-containing steel alloy strip, in which the strip is annealed in a first stage in order to obtain iron enrichment on the strip surface. Subsequently, the tape is heated in a non-oxidizing atmosphere to the temperature of the coating metal.
  • JP 02285057 A it is known to galvanize a steel strip in a multi-stage process.
  • the previously cleaned band is treated in a non-oxidizing atmosphere at a temperature of about 820 ° C.
  • the tape is treated at about 400 ° C to 700 ° C in a weak oxidizing atmosphere before being reduced on its surface in a reducing atmosphere becomes.
  • the cooled to about 420 ° C to 500 ° C strip is galvanized in the usual way.
  • the invention has for its object to develop a process for hot dip coating a strip of high strength steel with zinc and / or aluminum, with which a steel strip is produced with an optimally finished surface in a RTF plant.
  • the strip is heated in a reducing atmosphere with an H 2 content of at least 2% to 8% to a temperature of 65O 0 C to 75O 0 C at which the alloying constituents do not diffuse or only in small amounts to the surface
  • the predominantly pure iron surface is characterized by a 1 to 10 sec continuous heat treatment of the strip at a temperature of 65O 0 C to 750 0 C in a continuous furnace integrated reaction chamber with an oxidizing atmosphere with a Ü 2 content of 0.01 % to 1% converted to an iron oxide layer.
  • the result is optimal if the iron oxide layer produced in the oxidizing atmosphere is completely reduced to pure iron, because then the coating is also optimized with respect to its deformation and strength properties.
  • the thickness of the forming oxide layer is measured and adjusted depending on this thickness and dependent on the passage speed of the belt treatment time of the O 2 content such that the Oxide layer can then be completely reduced.
  • the change in the throughput speed of the belt for example as a result of disturbances can be considered in this way without detriment to the surface quality of the hot dip coated strip.
  • Good results have been achieved in carrying out the method when an oxide layer with a maximum thickness of 300 nanometers is produced. Good results were also obtained when the upstream oxidation of the band heating to 650 to 75O 0 C max. Takes 250 seconds.
  • the oxidation followed by heat treatment followed by cooling of the tape should last longer than 50 sec.
  • the high-strength steel should contain at least one of the following constituents: Mn> 0.5%, Al> 0.2%, Si> 0, l%, Cr> 0.3%.
  • Other ingredients such as e.g. Mo, Ni, V, Ti, Nb and P can be added.
  • An essential feature of the invention is that the heat treatment of the strip in the reducing atmosphere takes much longer in both the warm-up and the subsequent annealing as compared to the heat treatment in the oxidizing atmosphere.
  • the volume of the oxidizing atmosphere is very small compared to the remaining volume of the reducing atmosphere.
  • This has the advantage that it is possible to react quickly to changes in the treatment process, in particular the throughput speed and the formation of the oxidation layer.
  • the heat treatment of the strip takes place in the reducing atmosphere in a continuous furnace with an integrated chamber with the oxidizing atmosphere, wherein the volume of the chamber to the remaining volume of the continuous furnace is many times smaller.
  • the inventive method is particularly well suited for hot dip galvanizing.
  • the molten bath may also consist of zinc-aluminum or aluminum with silicon additives. In any case, whether zinc or aluminum alone or together, their share in the melt should total at least 85%.
  • characteristic coatings are for example:
  • the cleaned belt 1 then passes into a continuous furnace 5.
  • the band 1 passes via a locked to the atmosphere lock 6 in a hot dip 7 with zinc.
  • From there it passes via a cooling section 8 or a device for heat treatment to a winding station 9 in the form of a coil.
  • the band 1 in reality does not run in a straight line through the continuous furnace 5, but meandering, in order to achieve sufficiently long treatment times at practical length of the continuous furnace 5 can.
  • the continuous furnace 5 is divided into three zones 5a, 5b, 5c.
  • the middle zone 5b forms a reaction chamber and is atmospherically closed with respect to the first and last zones 5a, 5c.
  • Their length is only about 1/100 of the total length of the continuous furnace 5. For better illustration, the drawing is not to scale extent. According to the different lengths of the zones and the treatment times of the continuous belt 1 in the individual zones 5a, 5b, 5c are different.
  • the first zone 5a there is a reducing atmosphere.
  • a typical composition of this atmosphere consists of 2% to 8% H 2 and balance N 2 .
  • the strip is heated to 650 to 75O 0 C. At this temperature, said alloying constituents diffuse in only small amounts to the surface of the strip 1.
  • the temperature of the first zone 5a is essentially kept only.
  • Their atmosphere is oxygenated.
  • the O 2 content is between 0.01% up to 1%. He can be hired. It depends on how long the treatment time is. If the treatment time is short, the C> 2 content is high, while it is low with long treatment time.
  • an iron oxide layer is formed on the surface of the belt. The thickness of this iron oxide layer can be measured by optical means. Depending on the measured thickness and the passage speed, the C> 2 content of the atmosphere is adjusted. Since the central zone 5b is very short in comparison to the entire furnace length, the chamber volume is correspondingly small. Therefore, the reaction time for a change in the composition of the atmosphere is small.
  • a further heating up to about 900 0 C takes place, in which the strip 1 is annealed.
  • This heat treatment is carried out in a reducing atmosphere with an H 2 content of 2% to 8% and balance N 2 .
  • the iron oxide layer prevents alloying constituents from diffusing to the strip surface. Since the annealing treatment takes place in a reducing atmosphere, the iron oxide layer is converted into a pure iron layer.
  • the band 1 is further cooled on its further way in the direction of the hot dip bath 7, so that when leaving the continuous furnace 5, it has about the temperature of the hot dip bath 7 of about 48O 0 C. Since the strip 1 is made of pure iron after leaving the continuous furnace 5 on its surface, it provides the zinc of the hot-dip bath 7 an optimal basis for a strong bond.
