Notch-corrosion-free color-coated steel plate for curtain wall and production process of color-coated steel plate
The invention belongs to the technical field of color-coated steel plates, and discloses a non-notch-corrosion color-coated steel plate for a curtain wall and a production process of the non-notch-corrosion color-coated steel plate. The color-coated steel plate comprises a base plate, a metal coating and a coating, wherein the substrate comprises the following chemical components in percentage by weight: 0.0005 to 0.007 percent of C, 0.06 to 0.15 percent of Si, 0.50 to 1.0 percent of Mn, 0.050 to 0.090 percent of P, less than or equal to 0.012 percent of S, 0.012 to 0.060 percent of Als, 0 to 0.040 percent of Nb, 0.019 to 0.060 percent of Ti, less than or equal to 0.006 percent of N and the balance of Fe and inevitable impurities; the metal coating is a high-aluminum coating or a pure-zinc coating. According to the invention, the design of ultralow-content interstitial solid solution atoms, a proper amount of solid solution strengthening atoms and trace alloy elements is adopted, and an adaptive fine grain structure regulation and control process and a high-durability and notching-corrosion-free coating process are matched, so that the production and manufacturing of the notching-corrosion-free, high-durability and high-formability punch-formed color-coated steel plate are realized.
本发明属于彩涂钢板技术领域，公开了一种无切口腐蚀的幕墙用彩涂钢板及其生产工艺。该彩涂钢板包括基板、金属镀层和涂层；其中，基板的化学成分按重量百分比计为：C：0.0005～0.007％，Si：0.06～0.15％，Mn：0.50～1.0％，P：0.050～0.090％，S：≤0.012％，Als：0.012～0.060％，Nb：0～0.040％，Ti：0.019～0.060％，N：≤0.006％，余量为Fe和不可避免的杂质；金属镀层为高铝镀层或纯锌镀层。本发明采用超低含量间隙固溶原子、适量固溶强化原子与微量合金元素设计，匹配相适应的细晶粒组织调控工艺和高耐久、无切口腐蚀的涂镀层工艺，实现无切口腐蚀、高耐久和高成形性冲压成型彩涂钢板的生产制造。
