一种高强钢的生产工艺方法
摘要：
本发明提供了一种高强钢的生产工艺方法，包括以下步骤：(1)对带钢进行预拉伸处理，纠正带钢的板形，并且使带钢两个表面的氧化铁皮产生均匀的裂解；(2)将预拉伸处理后的带钢在酸洗槽内进行低温酸洗，设定酸洗温度T1；(3)将酸洗后的带钢在漂洗槽内进行低温漂洗，设定漂洗温度T2；(4)将漂洗后的带钢使用平整机进行平整处理；(5)将平整后的带钢使用拉矫机进行拉矫处理。将拆卷后的带钢进行预拉伸处理，然后经过低温酸洗和低温漂洗后，再进行平整、拉矫处理，提高高强钢的表面质量，提高高强钢产品的合格率，实现了高强钢在酸平线的生产。
摘要（英）：

The invention provides a production process method of high strength steel. The production process method comprises the following steps that (1) pre-stretching treatment is conducted on the strip steel, the shape of the strip steel is corrected, and uniform cracking is conducted on the iron oxide scales on the two surfaces of the strip steel; (2) low temperature pickling is conducted on the pre-stretched strip steel by placing the pre-stretched strip steel in a pickling tank, and the pickling temperature T1 is set; (3) the pickled the strip steel is subject to low temperature rinsing in a rinsing tank, and the rinsing temperature T2 is set; (4) the rinsed strip steel is leveled by using a leveling machine; and (5) the leveled strip steel is subject to straightening and withdrawal by using astraightening and withdrawal machine. The rewound strip steel is pre-stretched, then is subjected to leveling and straightening and withdrawal after being subject to low temperature pickling and lowtemperature rinsing, the surface quality of the high strength steel is improved, the qualified rate of high strength steel products is increased, and the production of the high strength steel in an acid level line.
