Definitions

  • the invention relates to a method for the surface treatment of hot-rolled Metal sheets or strips - especially steel - for removal of scale or surface oxides, with the rolling stock over an outlet section is promoted to a reel.
  • the material In the production of thin sheets or strips of steel - whether after conventional hot wide strip rolling or when casting and rolling thin slabs - the material is exposed to the air during the forming in the rolling stands as well as on the subsequent runout or the cooling roller table. so that the surface of the rolling stock is inevitably scaled due to contact with the atmospheric oxygen.
  • the growth rate as well as the type of scale layers that are formed depend essentially on the alloy composition of the rolled material and the temperature / time cycle used. At temperatures above 570 ° C, for example, the main product in the oxidation of iron is FeO layers, below 570 ° C Fe 2 O 3 and Fe 3 O 4 layers, and oxides of the respective alloy components in alloyed steels.
  • the rolled strip usually runs over the cooling roller table with water cooling elements to a reel device, often in the cooling roller table as well the mechanical properties via the temperature selection in the reel device of the band are adjustable.
  • the Coiler device influences the temperature on scale formation and setting the mechanical properties in the opposite direction by adjusting the structure behavior.
  • the scale layer in the wound coil grows in the area of Band edges stronger than in the because of the better contact to the atmospheric oxygen Middle of the strip, especially at high reel temperatures.
  • a disadvantage of the setting The mechanical properties in the hot strip mill is that the Temperature distribution over coil length and width undefined and especially on Coil end and beginning is inhomogeneous. Accordingly, the mechanical Properties of the finished products must be inhomogeneous.
  • the coiled, scaled, hot strip of a pickling line is usually used fed to scale and surface oxides by means of passage in salt or remove sulfuric acid media from the belt surface.
  • a certain amount Rolling volume to be conveyed by the pickling liquid is necessary.
  • the rolling stock volume increases with decreasing hot strip thickness with the same surface throughput from.
  • the increase in surface throughput by increasing the Throughput speeds are nevertheless limits with the known pickling techniques set.
  • the surface treatment of increasingly thin hot strip pickling plants cannot be followed arbitrarily.
  • the invention has for its object a method and a System for the surface treatment of hot-rolled sheets or strips to provide with the above all thin tape with high surface quality homogeneous mechanical properties across belt length and width economically can be manufactured.
  • This object is achieved in a generic method in that a first step, the rolling stock immediately after the last shaping step in the rolling mill - i.e. after leaving the finishing stand - homogeneous is cooled to a temperature at the rolling stock width and length at which scaling of the rolling stock is restricted or suppressed, and that in a second step to complete the possibly slightly scaled rolling stock Descaling its surface and setting the desired one mechanical properties subjected to annealing in a reducing atmosphere becomes.
  • This annealing preferably takes place with a simultaneous reduction of scale layers in a continuous annealing furnace sealed from the outside atmosphere rather than with a heating, holding and cooling zone, with the initial Heating zone the belt to temperatures in a range of 500-800 ° C, preferably about 550 ° C, is heated.
  • the rolling stock is in one the second heating zone directly adjoining the first heating zone Temperatures in the range of 700 to 800 ° warmed.
  • the holding zone is mainly used for descaling the surfaces and setting of the desired structure under the influence of time.
  • the continuous furnace consists of chambers that are gastight from the air atmosphere and contains reducing gases, preferably 100% hydrogen.
  • reducing gases such as carbon monoxide or hydrocarbons and their Mixtures or mixtures of hydrogen and nitrogen are also conceivable.
  • hydrogen has two advantages. It reacts with the oxygen the in a continuous furnace by the continuous conveyance of the rolling stock through the introduced air, which cannot be completely avoided, into water. In addition, the decarburization of the rolling stock surface by hydrogen is very low.
  • a 100% hydrogen atmosphere is particularly recommended at high or higher alloyed steels, as the alloy metals are usually more sensitive to oxidation are as iron.
  • the proposed method can end with the annealing step, whereby Make sure that in the cooling zone of the sealed continuous furnace the rolling stock is already cooled to a temperature of about 100 ° C by one Reoxidation when the rolling stock emerges from the furnace and comes into contact again to prevent atmospheric oxygen.
  • the tape is wound up immediately afterwards and is a glow product with a descaled surface and a homogeneous finish Structure available.
  • the continuous annealing process can immediately be followed by a surface coating connect, preferably in the form of a hot-dip coating line for coating with zinc or aluminum alloys.
  • a surface coating connect preferably in the form of a hot-dip coating line for coating with zinc or aluminum alloys.
  • the rolling stock is brought to a temperature in one in the cooling zone Cooled temperature range between 400 to 700 ° C and then immediately the surface treatment subject.
  • a suitable one for carrying out the method is also used Attachment proposed.

  • Hot-rolled strip can be provided surface-coated without any negative Influence on the structure.
  • Figure 1 shows schematically the sequence of the proposed method as well the necessary investment units.
  • the two embodiments of the Processes differ in the treatment of the rolling stock in the cooling zone of the continuous annealing furnace, which will be discussed later.
  • the method according to the invention can be used in conventional hot wide strip mills as well as in plants for the production of thin strip (see FIG. 2) Find.

  • a cooling device 5 is arranged according to the invention, which Hot strip 6 cools down at an adjustable speed.
  • the temperatures to be reached should be below 450 ° C.
  • With the help of the cooling rate and the cooling temperature is the desired structure - pure martensite, bainite or ferritic-pearlitic structure or mixed structure - adjustable. That so frightened Volume 6 is without further major formation of scale or surface oxides transported to the reel device 4. Located on the belt surface only the scale or surface oxides that form during the rolling process have formed.
  • the coil 7 rolled up in the reel device 4 is then separated arranged continuous annealing furnace 8 supplied. According to an embodiment not shown it is also conceivable that the annealing furnace in the outlet section of the Rolling mill is integrated.
  • the already completely cooled or still warm coil 7 is in an unwinding device 9 unrolled, and via a welding device 10 in an inlet memory 11 funded.
  • These three system elements form the inlet group 12 of the continuous annealing furnace.
  • From there it continuously enters the annealing furnace 8 preferably has a 100% hydrogen atmosphere.
  • the seals of the annealing furnace on both sides can be realized with dynamic gas seals.
  • the furnace is divided into three basic zones 13 (heating zone), 14 (holding zone), 15 (cooling zone), the heating zone 13 being divided into a first (13a) and divides a second (13b) heating zone.
  • the first heating zone 13a is preferably provided with an induction furnace, which quickly heats the belt to temperatures of around 550 ° C.
  • a relatively long holding area 14 in which essentially under the reducing conditions the descaling process and the setting of the desired structure takes place.
  • a cooling process then closes Reeling on.
  • the band in the cooling zone 15 to a Temperature cooled below 100 ° C, with the cooling rate and the cooling medium, the desired structure is adjustable.
