Definitions

  • the invention first relates to a process for the production of steel strip for parts produced by deep drawing or ironing, in which a hot strip is cold-formed in one or more stages and with a degree of cold rolling of at least 86 °, at least one side of the strip material having an electroplated coating containing Ni, Co, Cu, Fe, Sn, In, Pd, Bi and / or their alloys or with a roll-plated coating containing Cu and / or brass and / or their alloys.
  • Cold rolled steel strip is often used for the production of rotationally symmetrically cold formed parts such as. B. battery sleeves used.
  • the processes used in cold forming are deep drawing on the one hand and ironing on the other hand, the latter also being referred to as the DI process (drawing and ironing).
  • DE-195 47 181 C1 describes a steel with proportions of titanium, vanadium or niobium, a type of mixed grain being achieved due to certain hot rolling conditions below the gamma range of the iron-carbon diagram and due to a high coiling temperature in the hot strip. At degrees of roll between 50 and 85%, this mixed grain leads to a reduced tip tendency, but also to the formation of coarse, line-shaped cementite, which leads to undesirable structures on the surface of the strip when deep-drawing thin parts with high surface demands and thus in practice to a scrap.
  • the hot strip preferably contains boron in a proportion between 0.0013 and 0.0060% by weight, the weight ratio of boron to nitrogen being 0.5 to 2.5. A boron fraction between 0.0013 and 0.0030% by weight is particularly desirable.
  • the hot rolling is preferably carried out with a roll temperature of over 870 ° C and a coiling temperature of below 710 ° C.
  • the value of the vertical anisotropy ⁇ r of the strip after the coil annealing should not be more than +/- 0.12.
  • the invention proposes a steel strip capable of deep drawing or ironing, which is produced according to a method according to at least one of the method claims.
  • the starting material is a hot strip with an initial thickness of 1.2 to 8 mm, preferably 2.0 to 2.5 mm.
  • the steel analysis of the hot strip used is as follows:
  • the steel composition is as follows:
  • the strip is hot-rolled with a final roll temperature of over 870 ° C and a coiling temperature of below 710 ° C, in order to ensure a particularly even structure of the steel strip.
  • the limit values for the yield strength between the edge and the center of the strip vary by less than 15 N / mm 2 .
  • the required hot rolling forces increase significantly. With boron contents below 0.0060% by weight, on the other hand, moderate hot rolling forces can be used. This also means that the thickness tolerance across the width of the strip is reduced due to the then significantly lower roll deflection.
  • the hot rolled strip is then pickled and then subjected to one or two-stage cold rolling.
  • the degree of cold rolling is 86% or more.
  • the starting material with a thickness of 1.2 to 8 mm can be cold rolled in this way to a final thickness of 0.1 to 1.0 mm.
  • Cold rolling is followed by recrystallization annealing in the coil, i.e. annealing the strip in the wound state.
  • recrystallization annealing comes very close in effect to normalizing, as is usually carried out in continuous furnaces with stretched strip.
  • the strip is further rolled in order to improve its surface and adjust the mechanical-technological values.
  • the steel strip is provided with an electroplated coating on at least one of its two surfaces.
  • the electrolytic finishing can follow the first or also the second stage of cold rolling, whereupon the annealing in the coil and the subsequent rolling of the strip then take place in further steps.
  • An additional annealing stage between the two cold rolling stages is also possible.
  • the coating can also be applied to the at least one side of the steel strip by roll cladding of metal foils.
  • the steel strip After hot rolling and pickling the steel strip, it is first roll-clad and then annealed in the coil. Possibly. The annealing in the coil can be followed by another cold rolling and a second annealing in the coil before the strip is finally subjected to the re-rolling process to improve the surface.
  • the strip which is finished electrolytically or by roll cladding, can additionally be provided with non-metallic or galvanic coatings in order to achieve special effects and properties.
  • the thickness of the entire galvanic coating on one or both sides of the steel strip should be 0.1 ⁇ m to 8 ⁇ m.
  • the sum of the one-sided or two-sided layers of plated metal can be up to 50% of the total thickness of the strip.
  • the parameters are set during the cold rolling so that, following the simple annealing in the coil, a vertical ansiotropy ⁇ r of max. +/- 0.12 results in a relative tip height of max. Corresponds to 2.5%. This also results in a round grain structure made of globular grain which is advantageous for later deep drawing or ironing.

Abstract

L'invention concerne un procédé pour produire de l'acier sous forme de feuillard pour des pièces produites par étirage, ainsi qu'un feuillard d'acier pouvant être embouti ou étiré, produit selon ce procédé. Ce feuillard d'acier est façonné à froid en une ou plusieurs étapes et avec un degré de laminage à froid d'au moins 86 %. En outre, au moins un côté du matériau du feuillard est pourvu d'un revêtement produit par voie galvanique et contenant du Ni, Co, Cu, Fe, Sn, In, Pd, Bi et/ou leur alliages, ou d'un revêtement plaqué par laminage, contenant du Cu et/ou du laiton et/ou leurs alliages. L'invention vise à créer un tel procédé, entraînant de faibles coûts de production et pouvant être mis en oeuvre avec le moins d'étapes possibles. A cet effet, ledit procédé comprend les étapes suivantes: décapage, laminage à froid en une ou deux étapes, recuit du feuillard à l'état enroulé, éventuellement relaminage du feuillard. Le feuillard à chaud contient de préférence une proportion de bore comprise entre 0,0013 et 0,0060 % en poids, le rapport en poids entre le bore et l'azote étant compris 0,5 et 2,5.
