武钢冷轧厂生产一百吨 B_1F 钢镀锌板,而出现废品就达数十吨。这批镀锌板的质量缺陷与以往有所不同。武钢生产的带钢连续热镀锌板常见缺陷为结疤、鼓包、裂纹等。这批 B_1F 钢镀锌板是锌未镀上去,钢基呈片块暴露在外,以致成废品。本文是利用电子探针 X 射线显微分析仪对废品镀锌板表面、 WISCO cold-rolled steel plant producing one hundred tons of B_1F steel galvanized sheet, and the emergence of scrap on the dozens of tons. The quality defects of these galvanized sheets are different from the past. WISCO produced continuous strip of hot-dip galvanized steel defects are scarring, bulging, cracks and so on. These B_1F steel galvanized sheet is not coated with zinc, steel-based pieces exposed, resulting in waste. This article is the use of electronic probe X-ray microanalysis of scrap galvanized sheet surface,
