Definitions
- a method of manufacturing a component from a steel product provided with an Al-Si coating A method of manufacturing a component from a steel product provided with an Al-Si coating and
- the invention relates to a method for producing a component from a steel product coated with an Al-Si protective coating. Moreover, the invention also relates to an intermediate product which arises in the course of such a process and can be used for the production of components of the type in question.
- Steel products of the type in question are typically steel bands or sheets, which are provided in a manner known per se, for example by fire aluminizing, with an Al-Si coating. However, it can also be preformed semifinished products, which are preformed, for example, from sheet metal and then molded to the respective component.
- the component formed from the respective steel product is protected against corrosion during its practical use.
- the corrosion protection effect in particular the protection against scaling, however, already provides the Al-Si protective coating immediately after the coating of the steel substrate and keeps it in the course of the forming process at. This applies in particular when the shaping is carried out as so-called "press-hardening".
- the starting material to be formed is brought to a temperature at which a at least partially austenitic microstructure is present, and deformed in the warm state before molding. Either already during the thermoforming process or immediately thereafter, the resulting component is then accelerated cooled to form Hartegefuge.
- a starting material for the press-hardening flat products such as sheet metal blanks, or already pre-or final molded semi-finished products can be used.
- the Al-Si coating prevents tinder from forming on the steel product, which would severely hamper the forming process. In this way, it is possible to form components from high-strength, treatable steel, which are exposed in practice particularly high loads.
- a steel good typically used for this purpose is known in the art as "22MnB5". From steel goods of this type, for example, body parts of motor vehicles are manufactured, which must have a high strength with low flat product thickness and, consequently, comparatively low weight. Likewise, however, other steel good, such as deep-drawing steels known under the trade name “DX55D”, according to DIN EN 10327 composite type, and microalloyed steels alloyed according to DIN EN 10292, under the Designation "HX300 / 340 LAD”, commercially available type. It is also possible to use the starting products, which are composed in the manner of tailored blanks / patchwork blanks of several sheets.
- Al-Si coating In order for the Al-Si coating to adhere to the steel substrate so strongly that it does not crack or flake off during forming, it is necessary to subject the Al-Si coated steel product to a heat treatment prior to forming, in which iron is precipitated the steel substrate is alloyed into the Al-Si coating.
- the aim is to pass through the coating over its entire thickness to ensure that there are no breaks or chips in the upper layers of the coating, which are adjacent to the free outer surface of the coated flat product.
- the type or degree of alloying of Al-Si coatings also has an influence on the weldability and paintability of the components produced by press-hardening.
- a method of the type described above is described in EP 1 380 666 A1.
- a coated with an Al-Si coating steel sheet is first heated to 900 0 C to 950 0 C over a period of 2 to 8 minutes.
- the coated steel sheet to 700 - 800 0 C cooled draw forming temperature hot forged at this temperature.
- the shaped steel member is cooled rapidly to a temperature below 300 0 C to produce a martensitic Gefuge in the obtained steel part.
- the heat treatment of the coating provided steel substrate is carried out so that by diffusion of the iron from the steel substrate after the heat treatment, the iron content in the coating in a range between 80% and 95%. In this way, a thermoformed component is to be obtained in which a good weldability and good formability combined with a high corrosion protection.
- a problem in carrying out the heat treatment required for the alloying out is that in addition to the setting of a sufficient heating temperature, a certain amount of oven resting time must be maintained. The duration over which the respective steel product must be kept in the oven results from the heating rate of the substrate and the required alloying of the substrate with the Al-Si layer.
- the prior art is a bake time of five to 14 minutes.
- the object of the invention was to provide a method which enables shortened processing times in the case of processors of Al-Si-coated steel products without the risk of corrosive attacks or disadvantages in a subsequent cutting of the coated flat products must be accepted.
- the steel product processed according to the invention can be a flat steel product, such as a steel sheet or steel strip, or a semifinished product preformed, for example, from a steel sheet, which is completely deformed during the hot pressing hardening carried out according to the invention. Also, in accordance with the invention, it is possible to process a plurality of blanks composed in the manner of tailored blanks / patchwork blanks.
- a two-stage heat treatment also takes place, it also being in accordance with the state of the art in the first heating stage for alloying iron from the steel substrate into the Al-Si coating.
- this first alloying step is carried out by setting a suitable temperature and duration of treatment so that the Al-Si coating after the first heating step is only partially alloyed with iron of the steel product. Subsequently, the steel product provided with the imperfectly alloyed coating according to the invention can be cooled to room temperature and stored until it is supplied to the respective component for further processing. Since the Al-Si coating is only partially alloyed in the first heating step, the Al-Si coating has low susceptibility to corrosion even after the first heating step, so that its storage, transport and other work steps carried out in advance of the second heat treatment are problem-free can be carried out without the need for additional measures.
- the flat product obtained after the first heating step and provided with a pre-alloyed coating according to the invention undergoes a second heating step.
- This second heating step is usually carried out at the final processor, while the first heat treatment step to be completed will usually be at the producer of the steel products.
- the second heating step is usually completed immediately before the hot forming.
- the steel product provided in the manner according to the invention with only a prealloyed Al-Si coating is heated to the heating temperature required for the subsequent curing, which is above the Acl-teroperatur at which the steel product has an at least partially frosted structure.
- the temperature and duration of the second heating step are erfmdungsgehold adjusted so that the Al-Si coating is completely alloyed in the course of the second heating step with Fe of the steel product.
- the coating according to the invention which is only partially alloyed with the steel substrate has a degree of reflection which, compared to the heating of flat products provided with completely alloyed Al-Si-Fe coatings, has a considerably higher heating rate when heated in a radiant oven
- An interim product obtained in the manner according to the invention is thus characterized in that it has only one with the iron of the steel substrate incompletely pre-alloyed Al-Si coating is provided.
- the starting material which is now provided with a fully alloyed Si-Al-Fe coating, is then converted in a manner known per se into a suitable thermoforming tool to form the desired component.
- the resulting component may be a finished-molded component or a semi-finished product which is subsequently subjected to further deformation steps.
- thermoforming is finally cooled in a controlled manner in order to produce hard joints in the steel substrate.
- the working steps “thermoforming” and “cooling” can be carried out in particular in the manner known from “compression molding”.
- the procedure according to the invention thus makes it possible, in a cost-effective and at the same time particularly efficient manner, to provide an aluminized component produced by press molding within shorter processing times. It is not the cost of the usually carried out at the producer of the steel product heating step due to the fact that the process time and the
- Treatment temperature for the partial Al alloy of the Al-Si layer with the iron of the steel substrate is shortened compared to the prior art, but also the usually at the processor of the inventive incomplete alloyed alloy Si coating carried out second heating step in a shorter process time can run at a correspondingly reduced energy consumption and minimal equipment.
- the temperature of the first heating is at least 500 0 C, but at the same time at most equal to the A c i temperature of the steel product.
- suitable temperatures for the first heating step in particular in the range of 550 - 723 0 C, in particular 550 - 700 0 C.
- the time to be planned for the first heating step at these heating temperatures amounts to Al-Si coating thicknesses in the initial state of 10 to 30 ⁇ m (corresponding to 80 to 150 g / m 2 ) for 4 to 24 hours when heated in a hood furnace. It is also conceivable to heat in a continuous furnace or chamber furnace, the heating times in each case be less than one hour.
- the temperature and duration of the first treatment step are in each case adjusted such that the Al-Si coating, measured starting from the steel substrate, is alloyed with Fe over at least 50%, in particular 70-99%, preferably 90-99%, of its thickness ,
- the first heating step may be carried out in a hood annealing furnace, a chamber furnace or a continuous annealing furnace.
- a master alloy in a continuous furnace, which is arranged directly inline at the outlet of a coating plant, similar to a plant for Galvannealmg the case and the heating in a temperature range between 600 and 723 0 C takes place.
- the obtained according to the invention provided with a partially alloyed Al-Si coating steel product in the second heating step in a continuous furnace to the required heating temperature to be heated.
- the second heating can be effected inductively, conductively or by means of thermal radiation.
- the samples were subjected to a heat treatment corresponding to the first heating step of the process according to the invention in a test oven simulated for a period of eight hours in a test-tube furnace.
- a first part of samples has been annealed at 500 0 C, a second part at 550 0 C and a third part at 600 0 C.
- further samples in six minutes at 950 0 C have passed through the continuous furnace. This represents a typical heat treatment for press-hardening in which the Al-Si coating layer is alloyed.
- the samples were cooled to room temperature.
- the resulting samples each had a not completely alloyed Al-Si plating layer down to the Warm-treated at 950 0 C sample.
- the previously annealed and cooled samples are in a second heating step was heated in a radiation oven to a heating temperature of 950 0 C in which the steel substrate Austenitgefuge possessed.
- the heating rates were recorded, ie it was monitored how quickly the samples were heated to the target temperature of 950 0 C.
- Diag. 1 the temperature T of the respective samples over the annealing time t is entered. Additional is in Diag. 1, the sample annealed for a sample not annealed in an upstream first heating step (curve "- 0 C / - s").
- the times required for the alloying out in the austenitizing furnace before the hot working can be significantly shortened. It was thus shown that a time saving of at least 90 s is expected compared to the conventional procedure can be. With this time gain, the required for the heating before the hot forming oven can be designed smaller. During maintenance of the conventional size furnace, cooling takes place to room temperature in about 10 days, whereas cooling of the furnace size possible by the invention can be expected to save at least 2 to 3 days in time.
