Definitions

  • the present disclosure relates to a plated steel sheet used in automotive outer panel, or the like, and in more detail, to a method of manufacturing a plated steel sheet having excellent image clarity after coating and a plated steel sheet manufactured thereby.
  • plated steel sheets plated with zinc (Zn), aluminum (Al), or the like have excellent corrosion resistance, weldability, and paintability
  • plated steel sheets have commonly been used as steel sheets for automotive outer panels. As such, plated steel sheets have been used in automotive outer panels, so that not only press formability, but also excellent image clarity after coating is required.
  • Image clarity after coating refers to the degree to which an image reflected on a painted surface is clearly viewable without being distorted, since a painted surface is smooth.
  • image clarity after coating has generally been treated as a task of painting technique (Patent Document 1), and a method of painting and the improvement of paint have commonly been reviewed. As a result, due to advancements in painting and paint technology, the quality of painting has been significantly improved.
  • a 2-coat painting system omitted a primer process, in which a surfacer or a primer coating process is omitted from a 3-coat painting system including a primer or an electrodeposition coating process of the related art, a surfacer or a primer coating process, and a sealer or base coating process and clear coating process.
  • the object of a primer coating process is to adjust surface unevenness of a concave-convex portion, an orange peel defect, or the like, on a surface of a plated steel sheet to be painted. Since a primer process is omitted, an overall thickness of a painting system may be significantly reduced, and a function of a primer coating process described above may not be performed. Thus, unevenness of a plated steel sheet may be exposed after painting.
  • Patent Document 2 a method of improving press formability and image clarity after coating in such a manner that solid particles are projected onto a surface of a galvanized steel sheet to adjust average surface roughness of a galvanized steel sheet, that is, an average surface roughness (Ra), to be 0.3 ⁇ m to 3.0 ⁇ m, a peak number per inch (PPI) of a surface of a steel sheet to be 250 or more (98 or more in the case of a peak number per centimeter (RPc)), and an average waviness (Wca) of a surface of a steel sheet to be 0.8 ⁇ m, respectively, is proposed.
  • Ra average surface roughness
  • PPI peak number per inch
  • Wca average waviness
  • a method of controlling an average surface roughness (Ra), a peak number per unit length (RPc), and average waviness (Wca) of a plated steel sheet having been temper rolled by adjusting a roughness and waviness of a roll after a temper rolling roll is processed using a laser process (LT) in Patent Documents 3 and 4 and an electronic beam process (EBT) in Patent Document 5.
  • LT laser process
  • EBT electronic beam process
  • An aspect of the present disclosure may provide a method of improving image clarity after coating of a plated steel sheet having no defect, even during painting, while avoiding an orange peel defect, a long wavelength waviness defect, occurring during a process of painting automobile components, as well as a plated steel sheet having excellent image clarity after coating, manufactured thereby.
  • a method of manufacturing a plated steel sheet having excellent image clarity after coating includes providing a cold rolled steel sheet by cold rolling; plating the cold rolled steel sheet to manufacture a plated steel sheet; and temper rolling the plated steel sheet by inserting the plated steel sheet into a temper rolling mill, wherein a long-wavelength waviness (Wsa1-5) of a final stand rolling roll is 0.4 ⁇ m or less during the cold rolling.
  • a plated steel sheet having excellent image clarity after coating the plated steel sheet being manufactured using a method described above and including a cold rolled steel sheet and a plating layer formed on the cold rolled steel sheet, wherein the cold rolled steel sheet has a long-wavelength waviness (Wsa1-5) of 0.2 ⁇ m or less, may be provided.

  • a roughness value such as an average roughness (Ra) and a peak number per unit length (RPc) of a plated steel sheet
  • image clarity after coating may be improved, while press formability of the plated steel sheet is not degraded.
  • the plated steel sheet of an exemplary embodiment has excellent image clarity after coating, thereby being applied to an automotive outer panels.

  • image clarity after coating may be improved by controlling the long-wavelength waviness of the cold rolled steel sheet itself.

  • the number 5 refers to a coarse form cut-off value removing a coarse form having a wavelength of 5 mm or greater in the form profile. Therefore, since the roughness component and a form covered by painting in the form profile is coarse, only a pure long-wavelength waviness in which the coarse form not observed due to an orange peel defect, or the like, is removed is illustrated.
  • Wca meaning the filtered center line waviness includes has the toughness component of 0.8 or greater, in which the cut-off value is 0.8 mm to 8.0 mm, and the coarse form component of 5 mm to 8 mm, the long-wavelength waviness observed as an orange peel defect may not be accurately illustrated.
