Description

一种SPCC-W黑皮钢板的生产方法
技术领域
本发明专利涉及一种SPCC-W黑皮钢板的生产方法，属于钢铁材料冷加工及热处理领域。
背景技术
退火工艺是冷轧产品常见的一种去应力、改善组织形态的工艺方法。黑皮钢因其用途对于加工变形、免涂装具有较高的质量要求。因此，生产难度较大，为了确保产品的表面、力学性能等指标的优异性，需要在成分设计及退火工艺上有一种新的方法以满足质量要求。常规的罩退工艺需要在氢气保护气氛下进行，但是黑皮钢由于质量要求特殊，需要改变保护介质。SPCC-W黑皮钢的生产，通过试验研究罩式退火工艺，设定加热温度、加热速度、保温温度、保温时间、保护气氛、保温平台等实现的。确保SPCC-W黑皮钢的表面质量、板型、力学性能等各项指标的优异性。SPCC-W等品种钢，由于表面质量要求特殊的发黑发蓝处理，高于普通SPCC钢种，在罩退生产过程中极易发生粘结等表面缺陷，导致产品降级。因此需要对工艺进行优化设计，降低能耗，提高质量。
发明内容
本发明的目的在于提供一种SPCC-W钢的生产方法，其实施操作方便，生产过程易控制、控制精度和安全性较高。
本发明的是这样实现的：一种SPCC-W黑皮钢板的生产方法，1、钢中的硅含量为：0.02%≤[Si]≤0.030%；2、黑皮钢卷的原料卷厚度为2.75mm，冷轧压下率为74.55%；冷轧卷的卷曲张应力控制在30Mpa以内；3、罩式退火工艺设计如下，保护介质采用氮气保护，0～440℃温度加热区间采用85～90℃/h的加热速度，在440℃保温3小时，确保轧制钢卷表面的乳化液残留物充分挥发，440～675℃采用41～51℃/h加热速度进行加热，退火保温温度设定为675℃，保温8小时，带加热罩冷却时间设定为0.5小时，摘加热罩温度630～650℃，温度高于650℃时继续带罩冷却；摘加热罩后再用冷却罩，空冷+水冷6小时，冷到280℃±10℃出炉，在终冷台上通风氧化，快速氧化形成特殊氧化层，外层形成以Fe2O3为主的致密氧化层。
采用本工艺生产SPCC-W黑皮钢不存在任何粘接缺陷，退火炉煤气消耗非常低，全程退火工序只需22小时，SPCC-W黑皮钢力学性能指标屈服强度、抗拉强度、延伸率满足产品标准要求；
本方法生产黑皮钢取得的效果。实施过程对9炉钢轧后的性能进行对比，具体指见表1。退火炉温度由700℃降低至675℃，带加热罩冷却时间由2小时降低至0.5小时以内，摘加热罩温度控制在650℃以下，冷却速度控制在40℃/h以下。达到既降低退火温度又缩短冷却时间的目的。同时确保钢板（钢卷）表面质量得到提升，力学性能稳定,完全满足用户使用要求， 钢材表面具有一层黑色的氧化铁皮（主要成分为Fe3O4,含量大于85%），钢材加工、使用时不需要涂层。

该发明主要用于SPCC-W黑皮钢的退火生产工艺，可以大幅度提高SPCC-W黑皮钢生产效率及产品质量。采用本技术生产的黑皮钢板屈服强度波动小，钢板的断后伸长率大于40%，可以在具有冷轧机组和罩式退火炉的企业推广使用。
具体实施方式
一种SPCC-W黑皮钢板的生产方法，1、钢中的硅含量为：0.02%≤[Si]≤0.030%；2、黑皮钢卷的原料卷厚度为2.75mm，冷轧压下率为74.55%；冷轧卷的卷曲张应力控制在30Mpa以内；3、罩式退火工艺设计如下，保护介质采用氮气保护，0～440℃温度加热区间采用85～90℃/h的加热速度，在440℃保温3小时，确保轧制钢卷表面的乳化液残留物充分挥发，440～675℃采用41～51℃/h加热速度进行加热，退火保温温度设定为675℃，保温8小时，带加热罩冷却时间设定为0.5小时，摘加热罩温度630～650℃，温度高于650℃时继续带罩冷却；摘加热罩后再用冷却罩，空冷+水冷6小时，冷到280℃±10℃出炉，在终冷台上通风氧化，快速氧化形成特殊氧化层，外层形成以Fe2O3为主的致密氧化层。
