Definitions
- the invention relates to a method for coating a 6-30 wt .-% Mn-containing hot- or cold-rolled steel strip with a metallic protective layer, in particular a protective layer based on zinc, wherein the steel strip to be coated at a 800-1100 C 0 amount forming annealing temperature under annealed a nitrogen, water and hydrogen-containing annealing atmosphere and then subjected to a hot-dip coating.
- steels with high manganese contents are, due to their favorable combination of properties consisting of high strengths of up to 1,400 MPa on the one hand and extremely high strains (uniform strains of up to 70% and elongations at break of up to 90%), particularly suitable for use in the field of vehicle construction , especially in the automotive industry.
- particularly suitable steels with high Mn contents of 6 wt .-% to 30 wt .-% are known for example from DE 102 59 230 Al, DE 197 27 759 C2 or DE 199 00 199 Al. From the known steels produced flat products have at high strengths isotropic deformation behavior and are still ductile even at low temperatures.
- Another method for coating a high manganese-containing, from 0.35 to 1.05 wt .-% C, 16 to 25 wt .-% Mn, balance iron and unavoidable impurities containing steel strip is known from WO 2006/042931 Al.
- the steel strip thus composed is first cold-rolled and then annealed recrystallizing in an atmosphere which is reducing with respect to iron.
- the annealing parameters are selected such that on both sides of the steel strip an intermediate layer is formed, which consists essentially completely of amorphous oxide (FeMn) O, and additionally adjusts an outer layer consisting of crystalline Mn oxide, wherein the thickness of two layers is at least 0.5 microns.
- Practical investigations have shown that even such complex precoated steel strips in practice not have the required for a cold deformation adhesion to the steel substrate.
- 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 power sufficient for the reduction of iron oxide but to prevent the selective oxidation of Si and Mn ,
- the object of the invention was to provide a method by which high cost manganese steel sheets can be hot dip coated in a cost effective manner.
- This object has been achieved in a method of the type specified in that according to the invention for the production of a substantially free of oxidic interlayers metallic protective layer on the steel strip, the ratio% H 2 O /% H 2 of the water content% H 2 O to hydrogen Content% H 2 of the annealing atmosphere is set as a function of the respective annealing temperature T G as follows:
- the invention is based on the recognition that by a suitable adjustment of the annealing atmosphere, namely its hydrogen content in relation to their water content and their dew point, adjusts a surface finish of the steel strip to be coated during annealing, the optimal adhesion of the subsequently by Ensures hot dip coating applied metallic protective coating.
- the inventively set annealing atmosphere acts both with respect to the iron and against the manganese of the steel strip reducing.
- the formation of, according to the inventors, adhesion of the melt coating to the high manganese steel substrate impairing oxide layer thus deliberately avoided.
- Typical applied in an inventive method calcination temperatures are in the range of 800 - 1100 0 C. Over the entire range of annealing temperatures should according to the invention, the% H 2 O /% H 2 - ratio are each below 4.5 * 10 ⁇ . 4
- the steel strip processed according to the invention is cold rolled one or more times, then the steel strip can be annealed under the annealing atmosphere set according to the invention during the intermediate annealing carried out between the individual cold rolling steps or during the annealing carried out after the cold rolling to prepare the hot dip coating.
- the annealing and the hot dip coating can be carried out in a continuous pass.
- This type of application of the method according to the invention is particularly suitable when the coating is carried out in a conventional coil coating plant, in which an annealing furnace and the hot dip are arranged inline in the usual way and are run continuously in succession in an uninterrupted sequence.
- the method according to the invention is suitable for hot dip coating of high manganese steel strips with a layer consisting essentially entirely of Zn and unavoidable impurities
- Z-coating with a zinc-iron layer, which consists of up to 92 wt .-% Zn and up to 12 wt .-% Fe (so-called "ZF coating"), with a Aluminum-zinc layer, whose Al content up to 60 wt .-% and whose Zn content up to 50 wt .-% (so-called "ZF coating"
- AZ coating is, with an aluminum-silicon layer having an Al content of up to 92% by weight and a Si content of up to 12 wt .-% (see called “AS coating”), with a zinc-aluminum layer having a content of up to 10 wt .-% Al, balance zinc and unavoidable impurities (so-called “ZA coating”) or with a zinc magnesium Layer which has a Zn content of up to 99.5% by weight and an Mg content of up to 5% by weight (so-called “ZnMg coating”) and additionally optionally up to 11% by weight.
