Definitions

  • the present invention relates to a method for producing thin-walled components made of steel, which have an inner core layer and outer edge layers, the layers consisting of differently tempered steel alloys and at least partially tempered.
  • the invention further comprises a thin-walled component made of steel with a core layer and martensitic hardened edge layers.
  • the process according to the invention is characterized in that core and surface layers made of steel materials with different tempering properties, namely in particular different martensitic hardenability properties, are combined with one another in such a way that thin-walled components are made available, which combine the respective advantages of case hardening and roll cladding.
  • Composite produces a strength distribution that is comparable to the case hardening curve, which is generally regarded as particularly advantageous.
  • case hardening there is practically no distortion in the method according to the invention, so that a precise, dimensionally and formally accurate component is made available without the need for dimensional corrections.
  • the flat alloy gradients specified according to the invention at the interfaces between the layers prevent the formation of internal material notches, as are inevitable in roll cladding as mentioned at the beginning. Thanks to the thus optimized hardness and strength gradient, there is no longer any risk that the boundary layers will flake off at the joint area, i.e. at the interface, when the load stress is exceeded, when the yield strength is exceeded.
  • the individual layers of steel alloys with different martensitic hardenability properties i.e. different contents of carbon, chromium and manganese are formed, the subsequent remuneration being carried out by martensitic or bainitic quenching, i.e. a heat treatment with the steps of heating-quenching-tempering.
  • the tempered layers consist of higher alloy, i.e. higher carbon steel than the unrefined layers.
  • the flat alloy gradient a correspondingly flat carbon gradient is realized in this case. This transition zone between high-carbon and low-carbon layers extends at one
  • Wall thickness of the components of less than 4 mm over less than 20%, preferably less than 15% of the wall thickness.
  • the coated layers preferably form the
  • Boundary layers of the components which are hard as a surface and have a hardness curve that roughly equates to case hardening.
  • the disadvantage of case hardening that due to the long residence time in the edge zones, a relatively coarse grain structure occurs, which leads to increased sensitivity to microcracks, is avoided by the layer arrangement according to the invention. Due to the relatively short dwell time, a wear-resistant fine grain structure with high toughness in the edge zone also results in the edge layers, which leads to a particularly low sensitivity to microcracks.
  • Components with a wall thickness of less than 4 mm can preferably be produced by the method according to the invention.
  • the tempered layers of the wall thickness i.e.
  • the martensitic hardened layers a cross-sectional proportion of about 10% to 50%.
  • the core layer of the components can also be quenched and tempered, for example hardened, while the edge layers consist of non-hardenable steel alloys or stainless steels.
  • the alloy gradient according to the invention between the surface and core layers can be produced by placing boards made of martensitic hardenable steel parallel to one another at a distance from one another in order to produce the composite material for the surface layers, and the core layer located between them is cast with molten, low-carbon steel.
  • molten, low-carbon steel For example, cold or surface-treated hot strip with predetermined chemical analysis, in particular a high carbon content, is used to form the surface layers. Due to the molten core material cast in between, which has a lower carbon content, the boards melt locally at the material interfaces, which results in a flat alloy or
  • Carbon gradient with a depth of about 0.1-0.3 mm. These properties are made possible by the connection according to the invention by means of a casting process close to the final dimensions.
  • the boards are preferably cooled from the outside by the casting wheels or the casting mold when the molten core material is poured in.
  • the width of the alloy gradient can be controlled so that it is in the range of 0.1 mm and is up to 10% of the total cross section.
  • the band which forms the edge layers is introduced into the casting gap on both sides along the rollers or copper jaws at the edge of the melt sump.
  • the Tapes should be bare, free of scale and oxide and, if necessary, roughened by appropriate surface treatment.
  • melt of the core material comes into contact with the strip surface, it is heated to above 950 ° C., so that a diffusion welding of the melt to the strip surface results in a metallic joining with the flat alloy gradient according to the invention.
  • band forming the outer layers the heat is given off further to the copper rollers or the mold walls, so that the bands do not melt completely, which would not be desirable.
  • the consequence of this casting composite in the wall thickness range close to the final dimensions is an increase in the casting performance, since the heat is dissipated by heating the supplied surface layers, that is to say the casting gap is cooled by the cold material supplied.
  • remuneration By means of partial heat treatment, for example by means of laser or electron radiation, locally limited remuneration, that is to say hardening, can take place.
  • remuneration can be given in the short-term continuous process, preferably in a protective gas furnace.
  • This enables particularly efficient production of functionally optimized strip material and components.
  • Particularly advantageous applications have a thin-walled component made of steel manufactured according to the aforementioned methods, with a soft core layer and martensitic hardened edge layers, which consists of a cold-formed, hardened multi-layer composite material which has carbon-rich, martensitic hardened edge layers and a core layer which is relatively low in carbon. the carbon gradient between the layers being flat.
  • the component can also have non-tempered surface layers, for example made of stainless steel alloys, and a tempered core layer, for example made of spring steel.
  • the wall thickness of the component according to the invention is preferably up to 4.0 mm.
  • the carbon gradient in the transition area extends over approximately 10 to 30% of the wall thickness, in any case more than 0.1 mm.
  • the materials for the outer and core layers are preferably matched to one another such that the hardness of the core layer corresponds to at least 30% to 50% of the hardness of the outer layers.
  • the component can consist of two different materials, for example a low-alloy core layer and high-alloy peripheral layers.
  • the chemical composition of the outer layers can also be different if required, so that a total of at least three layers with different material properties are present. This enables a further improved functional optimization of the components, such as corrosion protection or fusion welding, to be achieved. Furthermore, in the case of those produced according to the invention
  • Fig. 2 is a schematic representation of a casting plant for the production of strip material according to the invention.
  • FIG. 1 shows a section through a cold-formed, martensitic surface layer-hardened component 1. This is preferably formed from strip material with a total thickness S, which is in the range from 0.3 to 4.0 mm.
  • the peculiarity of the component 1 shown is that the layers A, B, A have already been connected to one another before the cold forming to the final dimension S in accordance with the method according to the invention, so that wide transition zones G have been formed at the layer boundaries, which are indicated by hatching and in which a flat carbon gradient has formed between the layer materials due to carbon diffusion and is in the range of several 1/10 mm.
  • the entire component 1 (FIG. 1) after it has been cold formed into a machine component, for example, has been subjected to a martensitic hardening process. As a result, the outer layers A are hardened, while the core B maintains a relatively high toughness.
  • Fig. 2 shows schematically a continuously operating two-roll casting and rolling system. This has two rotating, water-cooled copper rollers 2, which limit a casting gap of 1-5 mm wide.
  • Molten material B is applied to the melt sump 3 from above via an immersion tube 4.
  • Tape material A is fed along the edges of the casting gap from supply coils. With the core material B encapsulated in the casting gap, the connection between the material A supplied as a steel hot band and the melt-supplied material B takes place there. Due to the high surface pressure at temperatures above 950 ° C during hot rolling, there is an optimal metallic joining in any case.
  • the system according to the invention shown can be used to produce steel layer materials with extremely different properties with regard to the tempering of the individual layers.
  • the cold-formable composite material can be processed particularly well and efficiently to its final dimensions.
  • there is no disadvantageous delay in hardness during the subsequent hardening and there is no risk of the edge layers flaking off. This is because they have a fine, tough hard structure, which does not lead to breakage of the component even under high loads or short-term overload.
