Definitions
- the present invention relates to a method of producing a component from a steel product coated with an Al-Si protective coating.
- Steel products such as steel strips or steel sheets, are nowadays provided with an Al-Si protective coating by means of fire aluminizing in order to be protected against corrosive influences.
- the steel products are usually alloyed with the iron of the base material. This requires longer Glühdauern.
- the invention is therefore based on the object to provide a method that overcomes the disadvantages of the prior art.
- the method for producing a component from a steel product coated with an Al-Si protective coating comprises the following steps:
- the corrosion protection oil consisting of a composition containing fatty acid esters
- a substrate consisting of a steel product coated with an Al-Si protective coating is first provided.
- the steel product in the present case is a steel sheet or steel strip which is coated with an Al-Sl protective coating.
- the steel product is coated by means of flame aluminizing.
- the substrate is heated to a temperature Ti such that the Al-Si protective coating is only partially pre-alloyed with Fe of the steel product.
- the only way incompletely alloyed substrate has a toughness that allows the resulting substrate to be cut or trimmed without damaging the protective overcoat.
- the heating of the substrate to the temperature Ti can in this case be carried out in a bell annealing furnace, chamber furnace or in a continuous annealing furnace.
- such incompletely alloyed Al-Si protective coatings have an Fe content of 25-50% by weight.
- the Al-Si protective coating consists of 10% by weight of Si, 25-50% by weight of Fe and the radical Al.
- a corrosion protection oil is applied to the surface according to the invention, the corrosion protection oil consisting of a composition containing fatty acid esters.
- the application of the anticorrosive oil to the pre-alloyed substrate can be carried out, for example, by spraying or immersion in a bath containing the anti-corrosion oil. Alternatively, the application of the anti-corrosive oil by means of a roll order process.
- the pre-alloyed substrate may be immersed in a bath containing the anticorrosive oil prior to cooling to room temperature to cool it in a process step and provide it with the temporary corrosion protection.
- the pre-alloyed substrate provided with the anticorrosive oil is transported.
- transport refers to all types of transport operations in which the pre-alloyed substrate is moved from a first location, such as a steelmaker, to a second location, such as a steelmaking facility or storage facility.
- the prealloyed substrate provided with the anticorrosive oil is heated to a temperature T 2 such that the Al-Si protective coating is completely alloyed with Fe of the steel product and the anticorrosive oil is removed without residue.
- the heating of the substrate to the temperature T 2 can be carried out inductively, conductively or by means of thermal radiation in a continuous furnace. Subsequently, the reheated substrate is formed into the desired component.
- the component is automobile bodies or parts thereof.
- the temperature T 2 corresponds to a temperature range of 850 ° C to 1000 ° C. More preferably, the temperature T 2 corresponds to 880 ° C to 930 ° C.
- the heating of the pre-alloyed substrate provided with the anticorrosion oil to the temperature T 2 comprises the following method steps:
- the heating to T 2 is preferably 60 to 210 s, preferably 90 to 180 s.
- the heating of the substrate is dependent on the thickness of the substrate and must be adjusted individually, based on the particular substrate used.
- the holding in the temperature range T 2 is preferably 60 to 600 s, preferably 30 to 120 s.
- the cooling is preferably carried out at a cooling rate in the range of 5 to 25 K / s, preferably in the range of 10 to 20 K / s.
- the cooling of the substrate takes place during the transfer of the substrate into a tool, in which the substrate is subjected to a forming process.
- the heating to T 2 is carried out under a protective atmosphere.
- a protective atmosphere dry air or an inert gas such as nitrogen gas may be used.
- the temperature Ti corresponds to a temperature range from 550 ° to 750 ° C, preferably from 550 ° to 700 ° C.
- the composition contains at least 98% by weight, preferably 98.5-99% by weight of the fatty acid ester.
- the gaseous combustion residues of C0 2 and H 2 0 and can be removed without further expensive measures together with the exhaust air from the furnace chamber.
- the fatty acid ester is a Ca - C ⁇ , more preferably a Cn - C 17 compound.
- the composition has a sulfur content in the range of 1-2% by weight, more preferably in the range of 1-1.5% by weight.
- the composition has a saponification number in the range of 150-265 mg KOH / g, more preferably in the range of 165-195 mg KOH / g.
- the anticorrosion oil is applied to the substrate in an amount of 0.5 to 2 g / m 2 , more preferably 0.7 to 1.7 g / m 2 .
- composition of the anticorrosive oil preferably contains no fats.
- the composition contains no additives or inhibitors.
- the anticorrosive oil is not removed from the substrate provided with the anticorrosion oil by means of a cleaning step before it is heated to the temperature T 2 .
- a complex cleaning device can be dispensed with within the process.
- the present invention relates to the use of a corrosion protection oil consisting of a composition containing fatty acid esters as a temporary corrosion protection in the storage and / or transport of prealloyed substrates consisting of a coated with an Al-Si protective coating steel product.
- the substrate consisting of a steel sheet in 1.5 mm sheet thickness of quality 22MnB5 in the hot dip process with a 25 ⁇ thick Al-Si protective coating provided.
- the protective coating contains 10% by weight of Si, 3% by weight of Fe and the radical Al.
- the steel product coated with the Al-Si protective coating was pre-alloyed as a prefabricated board at 700 ° C in a forced air oven.
- the Al-Si protective coating of the pre-alloyed steel plate now contains 30 wt .-% Fe, 10 wt .-% Si and the rest AI. Subsequently, 0.5 g / m 2 of a corrosion protection oil are applied in the roll application process.
- the anticorrosive oil used herein is a fatty acid derivative of a native oil that contains no other additives or inhibitors. These boards are processed after transport and storage in non-sheltered place. Before further processing, no changes in the surface or corrosion damage could be detected. For further processing, the boards are fed by means of industrial robots a hot forming furnace and austenitized at 925 ° C in 2.5 minutes so far that they can then be transformed and cooled in the cooled tool. Measurements on the hot forging furnace gave no further emissions in the furnace atmosphere except CO2, H 2 0 and the already existing furnace atmosphere in the form of nitrogen. Also on the press-hardened component no residues of the applied oil could be detected.
