Definitions
- JP 07-216524 A discloses a method of hot dipping a hot rolled steel plate having a high tensile strength.
- the steel plate is first descaled, pickled and cleaned. Then, it is lightly oxidized to produce thereon an iron oxide film having a thickness of 500 - 10,000 ⁇ .
- This iron oxide film is then reduced by reducing heating to active metallic iron. The reducing heating is carried out in such a way that a selective oxidation of Si and Mn in the steel and a concentration of these elements on the surface are avoided.
- the reductive heating is carried out under an atmosphere whose hydrogen concentration is controlled in the range of 3 to 25% by volume so as to have a reducing ability sufficient for the reduction of iron oxide but to prevent the selective oxidation of Si and Mn ,
- Hot dip reaction a conditioned steel surface is available which not only lends itself to being wetted particularly well, but also ensures adhesion of the coating, which reliably withstands the stresses which occur, for example, during cold deformation.
- the process according to the invention can be carried out particularly economically if the pickling treatment is completed in a continuous process. If such a continuous pickling treatment is combined with a likewise hot-dip coating, the time sequence of the working steps can be coordinated in a simple manner such that the risk of new formation of manganese oxide on the surface of the flat steel product to be coated at the transition from the pickling device in the Hot dip coating plant is reduced to a minimum.
- the flat product to be processed is annealed before being coated, it proves to be favorable in terms of the productivity of the overall process, even though the annealing apparatus with the stainer and the hot-dip coating equipment are passed in line in a continuous sequence ,
- a particularly important embodiment of the invention is characterized in that the flat steel product is dried before it enters the melt bath. In this way it is prevented that Beizmannmaschine enters the hot dip coating plant and there adversely affects the result of the hot dip coating.
- ZnMg coating a zinc-magnesium layer
- ZnMg coating which has a magnesium hydroxide content.
- a substantially Al-based coating so for example an AZ or AS coating has been applied in accordance with the invention
- This can be done, for example, by applying the zinc layer to the hot-aluminizing layer by electrolytic coating, re-immersion in a Zn bath, or vapor deposition (for example, by a PVD method).
- the single FIGURE shows an enlarged view of a sample of a steel sheet according to the invention provided with a zinc coating after a ball impact test.
- the cold strip thus obtained is then under a Gluhatmosphare, consisting of 95 vol.% Nitrogen and 5 vol.% Hydrogen at a temperature of 830 0 C at a belt speed of 100 m / min in a continuous flow annealed recrystallizing Service.
- the dew point of the Gluhatmosphare has been kept at --30 0 C.
- a cold rolled and recrystallized annealed steel strip was produced in the same manner as described for the first experiment.
- this steel strip has also been freed from the manganese oxide layer by immersion in a hydrochloric acid bath.
- two pickling baths of different concentration are used sequentially Service.
- the first pickling bath again contained 73 g HCl / L while the second pickling bath had 120 g HCl / L.
- the residence time in each pickling bath was 20 seconds per unit length of steel strip.
