Definitions

  • the invention relates to a method for producing a part with very high mechanical characteristics, shaped by hot stamping, from a strip of rolled steel sheet and in particular hot rolled and coated with a metal or a metal alloy providing protection of the surface and steel.
  • the steel sheets to be subjected to high temperature forming and / or a heat treatment are not delivered coated for reasons of resistance of the coating during the heat treatment, the heat treatment of the steels generally being carried out at relatively high temperatures well above 700 ° C. Indeed, a coating of zinc deposited on a metal surface has been considered until now as being able to melt, flow, foul the hot forming tools, during heating, at temperatures above the melting temperature of zinc , and degrade during rapid cooling.
  • the coating is therefore performed on finished part which requires a careful cleaning of surfaces and hollow parts.
  • This cleaning requires the use of acids and / or bases whose recycling and storage are a significant financial burden and present risks for operators and the environment.
  • the heat treatment must be carried out under a controlled atmosphere in order to avoid decarburization and oxidation of the steel.
  • calamine by its abrasive power, damages the forming tools, which reduces the quality of the parts obtained from the dimensional and aesthetic point of view or requires frequent and expensive repairs tools.
  • the parts thus obtained must receive an expensive post-processing whose application is difficult or impossible, especially in the case of parts with depressions.
  • the post-coatings of steels with very high mechanical characteristics also have the disadvantage of creating hydrogen embrittlement risks in electro-galvanizing techniques or modifying the mechanical properties of these steels in dip galvanizing techniques. previously formed parts.
  • the object of the invention is to propose to the users, steel sheets rolled from 0.2 mm to about 4 mm thick, coated in particular after hot rolling, and to be subjected to hot forming , as well as a method of producing a part by hot forming, from these coated steel sheets, the temperature rise being ensured without decarburization of the steel of the sheet, without oxidation of the surface of said sheet metal , before, during and after hot forming and heat treatment.
  • the method according to the invention as shown in the diagram of the figure 1 consists, from a sheet of a steel for heat treatment and hot forming, in particular hot rolled and coated with zinc or a zinc-based alloy, in the production of a hot-formed part in the form of tool means such as a stamping press.
  • the zinc or zinc alloy coating is selected so as to provide corrosion protection for the base sheet in a coil.
  • the coating forms a layer which combines with the steel of the strip and present at this moment a mechanical strength avoiding the melting of coating metal.
  • the formed compound has high resistance to corrosion, abrasion, wear and fatigue.
  • the coating does not alter the formability properties of the steel and thus allows a wide variety of cold and hot forming.
  • the strip After hot rolling, the strip can be pickled and cold rolled before being coated. In the case where the sheet is cold rolled, it can be annealed before being coated.
  • the rolled sheet can be coated, for example, with zinc, or zinc aluminum alloys.
  • the sheet can be cold stamped to obtain the piece.
  • the resulting part is then subjected to a heat treatment to give it high mechanical characteristics.
  • a base steel having a breaking strength Rm of about 500 MPa will make it possible to obtain heat-treated parts having a steel with a resistance Rm greater than 1500 MPa.
  • the sheet is subjected to a temperature rise of between 700 ° C. and 1200 ° C. in an oven with an atmosphere that does not require any more control, because of the barrier to the oxidation formed by the coating.
  • a temperature rise of between 700 ° C. and 1200 ° C. in an oven with an atmosphere that does not require any more control, because of the barrier to the oxidation formed by the coating.
  • the zinc-based coating is transformed into an alloyed surface layer having different phases depending on the temperature treatment and having a high hardness of more than 600 HV 100g.
  • sheets having a thickness of between 0.2 mm and 4 mm may be used, having good shaping properties as well as good corrosion resistance.
  • the sheets delivered coated have a significant resistance to corrosion during temperature rises, shaping, heat treatments, and during the use of finished formed parts.
  • the presence of the coating during heat treatments or hot forming avoids in addition to corrosion, the decarburization of the base steel.
  • This has an undeniable advantage in the case of hot forming, for example in a stamping press.
  • the formed intermetallic alloy avoids the formation of calamine, the wear of the tools by calamine, and thereby allows an extension of the average life of said tools.
  • the hot formed intermetallic alloy has a high temperature lubricant function.
  • the effect of protection against decarburization of the intermetallic alloy allows the use of high temperature furnace exceeding 900 ° C having an uncontrolled atmosphere, and this, even for heating times of several minutes.
  • the parts obtained Due to the characteristics of the coating after temperature rise, the parts obtained have an increased resistance to fatigue, wear, abrasion and corrosion, including on the wafer because of the galvanic behavior of the zinc with the steel.
  • the coating is weldable before and after temperature rise.
  • the steel of the sheet ensures, by cooling quenching effect, high mechanical characteristics of the part obtained after forming, the coating converted into a hot intermetallic alloy, for its part, because of its lubricant qualities and resistance to friction, an improvement in shaping, especially in the field of hot stamping.
