Definitions
- the invention relates to a method for producing a cold-rolled, up to 0.5 mm thick flat steel product for deep-drawing and ironing applications. Moreover, the invention relates to a flat steel product produced according to such a method and to an advantageous use of a corresponding flat steel product.
- Hot strip production are coordinated so that a continuous sequence of casting and the
- Hot strip which is intended in particular for the production of tinplate with a typical thickness of at most 0.5 mm, in particular at most 0.251 mm, could therefore not be produced in the past on a casting-rolling plant. Tinplates of this thickness will be
- Continuous casting in the slab or thin slab also does not crush residual calcium aluminate inclusions during hot rolling, but retain their size.
- Macroscopic Ca-aluminate inclusions can therefore be used in cold rolling or forming processes, for example, shell defects on the
- Molten steel is poured into a slab or cast strip containing (by weight) ⁇ 0.003% C, 0.5-0.35% Mn, ⁇ 0.025% P, ⁇ 0.020% S, ⁇ 0.004% Si, ⁇ 0.002 AI, ⁇ 0.004% N, in total ⁇ 0.1% Cr, Cu, Ni, Sn and Mo, ⁇ 0.004% N, each ⁇ 0.005% Nb, Ti, Zr and V, ⁇ 0.0030% B and balance Fe and unavoidable impurities.
- the steel melt according to the known method after its melting is first subjected to a vacuum treatment and then a ladle furnace treatment.
- the oxygen activity of the molten steel for continuous casting or strip casting should be as low as possible in order to avoid pore formation in the cast product and casting defects.
- Adjustment of the oxygen content or the oxygen activity takes place by a targeted addition of aluminum in an amount which, depending on the result of monitoring the current
- Oxygen activity of the melt is determined according to the target that the oxygen content of the melt at the end of the pan treatment is below 100 ppm.
- Step a) produces a steel melt containing (in% by weight) up to 0.008% C, up to 0.005% Al, up to 0.043% Si, 0.15-0.5% Mn, up to 0.02% P , up to 0.03% S, up to 0.020% N and each optionally up to 0.03% Ti and up to 0.03% Nb, the remainder containing iron and unavoidable impurities, the unavoidable
- the S-contents of the melt according to the invention are typically in the range of 0.005-0.03 wt%.
- the Al content of the melt is typically at least 0.001% by weight.
- Optimal Al contents of the molten steel ready for casting are in the range of 0.001-0.002% by weight.
- the molten steel is subjected to a secondary metallurgical treatment during production, omitting a Ca treatment, which, in addition to a conventional vacuum treatment, produces a ladle furnace.
- Treatment includes. In the ladle furnace treatment, the molten steel
- Mn content% Mn and Fe content% Fe is% Mn +% Fe ⁇ 15 wt. -%, in particular ⁇ 9 wt .-%.
- the measures provided for in the production of the molten steel according to the invention are based on the finding that the ladle slag must be kept well fluid for a good absorption of non-metallic inclusions in the melt. This can be done by a conventional
- Vacuum treatment in a RH or DH plant can not be achieved.
- the ladle furnace treatment according to the invention however, the ladle slag can be intensively liquefied via the heating with electrodes. As a result, it is very well suited to absorb non-metallic inclusions rising to the bath surface and thus further improve the degree of purity of the molten steel after the vacuum treatment.
- the inventive method is also that in the vacuum and the subsequent ladle furnace treatment slag is kept in contact with the molten steel, in which a certain oxygen potential is set before the vacuum treatment.
- This Oxygen potential "a 0 -Slag" of the ladle slag must correspond to the required oxygen activity "a 0 -Melt"
- Oxygen activity a 0 deposit is too high, it results in the unfavorable situation that, due to the tendency to
- Ladle slag can be used.
- Ladle slag to less than 15 wt .-%, in particular ⁇
- the molten steel produced in the manner according to the invention is continuously cast into a strand in step b), from which one or more thin slabs are then separated in a conventional manner, which are subsequently separated in a continuous process sequence
- Precursor is then in step c) in
- the respective precursor can be brought to a temperature of 1000 - 1250 ° C optimal for the further process sequence before hot rolling. This can
- Hot rolling itself will optimally with a
- Hot rolling start temperature which is in the range of 950 - 1200 ° C
- a hot rolling end temperature which is in the range of 800 - 950 ° C.
- Cold rolling may be preceded by a surface treatment which mechanically or chemically removes scale and other contaminants adhering to the hot strip in a conventional manner.
- the cold rolling itself can be one or more stages
- the first stage of cold rolling should be carried out with a degree of deformation of more than 85%, in particular more than 90%, and the second stage of cold rolling with a degree of deformation of 0.4-50%, in particular at least 1% , where degrees of deformation of 4 - 42% are particularly practical.
- the cold-rolled steel flat product according to the invention can be coated with a metallic protective layer.
- a metallic protective layer it may for example be an electrolytic
- Casting rolling process can be avoided by producing the flat steel products based on an alloy concept with minimized Al contents.
- low ⁇ l contents can be dispensed with a Ca treatment of the melt, so that the formation of the deformation properties interfering calcium aluminates is excluded.
- flat steel products produced according to the invention fulfill the highest demands on their formability. So they are suitable for all forming applications, for one according to ISO 11531 certain tension of less than 0.86 mm is required. In particular, are suitable
- flat steel products produced according to the invention are particularly suitable for the production of packaging for loose goods.
- These packages are typically cans and similar containers suitable for packaging
- flat steel products according to the invention can be used for the production of closures for such containers, bottle caps for closing bottles or spray cans.
- the flat steel product according to the invention leads to the
- the degree of purity is before the refining process, which may for example be in the form of the order of a metallic coating, such as a tinning or chrome plating, based on the number of non-metallic inclusions with an extent> 70 pm means
- Electromagnetic measurement method has been determined over the entire volume. The classification was based on the number of inclusions per m 2 according to the following conditions:
- very good rated samples can be used without restriction for all packaging steel applications.
- "Satisfactory” rated samples may be for certain, uncritical
