Description

一种易开盖用镀锡板及其生产方法
技术领域
本发明属于钢板冶炼技术领域,具体涉及一种易开盖用镀锡板及其生产方法。
背景技术
冷轧易开盖用镀锡板是热轧卷经过冷轧、退火、电镀工艺制造过程而形成的,其对于冲压成形性能具有严格要求,但目前普遍存在着易开盖冲压成形过程中铆接开裂现象,原因其一是采用LF精炼会产生数量较多的夹杂物,且N含量较高会降低带钢塑性,使得冲压成形过程中开裂几率大大增加;其二是热轧卷取温度低于600℃会产生带状组织,带状组织的存在会使得带钢的力学性能会呈各向异性,即沿带状组织方向性能明显优于垂直于带状组织方向的性能。
发明内容
解决的技术问题:针对上述技术问题,本发明提供一种易开盖用镀锡板及其生产方法,能有效解决上述镀锡板在冲压成形过程中出现开裂或延伸率异常断裂等不足之处。
技术方案:一种易开盖用镀锡板,所述镀锡板包括带钢和镀锡层,所述镀锡层覆盖在所述带钢的表面;其中,所述带钢以质量百分比计包括如下组份:C: 0.05~0.07%、Si≤0.03%、,Mn:0.16~0.24%、P≤0.02%、S≤0.01%、Al:0.03~0.06%、N≤0.0035%,其余为铁和不可避免的杂质。
一种易开盖用镀锡板的生产方法,包括以下步骤:转炉冶炼、RH炉精炼、连铸、加热、粗轧、精轧、冷却、卷取、冷轧、退火及电镀工序,其中转炉冶炼-RH精炼-连铸采用转炉出钢结束和RH炉出钢结束后分别投放200~500kg铝质渣面脱氧剂的二步顶渣改质法,且转炉终点氧的质量百分比≤0.065%,RH合金化前氧的质量百分比≤0.03%,RH合金化后净循环时间为8~12min,RH处理结束渣中全铁含量与氧化锰含量之和≤10%,结晶器液面波动≤3mm,浇铸过热度为23~37℃。
优选的,终轧温度为845~885℃,卷取温度为600~660℃。
优选的,退火工序中加热或均热段温度为675~685℃,退火速度为440~460mpm,平整延伸率为1.1~1.5%。
优选的,电镀工序中带速为330~350mpm,软融温度为230~270℃。
优选的,成品带钢夹杂物粒径≤20μm,成品带钢夹杂物数量≤15个/mm2
有益效果:本发明可大幅减少夹杂物数量,且夹杂物尺寸基本保持不变;将卷取温度控制在600~660℃范围内,带钢不会产生带状组织,这使得带钢铆接开裂大大降低,满足易开盖所需的成形性能。
附图说明
图1是本发明实施例1制得的铸坯样的夹杂物典型形貌与成分;
图2是本发明对比例2制得的带钢的金相组织图;
图3是本发明实施例1制得的带钢的金相组织图;
图4是本发明实施例3制得的带钢的金相组织图。
具体实施方式
下面结合附图1~4和实施例1~3以及对比例1~2对本发明作详细说明,如表1~3所示。
1. 实施例1-3与对比例1-2分别采用表1中化学成分冶炼获得钢水。
表1 化学成分表

2. 将所得钢水通过控制表2中关键工艺得到镀锡板成品。
表2 关键工艺点及参数
Figure 142507DEST_PATH_IMAGE002
3. 实施例1-3与对比例1-2的镀锡板成品性能如表3所示:
表3各电镀锡成品夹杂物与性能
Figure 737437DEST_PATH_IMAGE003
4. 对比例1中,精炼方式采用LF工艺,其他化学成分与工艺参数类似于实施例1,但对比例1所得镀锡板成品的夹杂物数量接近30个/mm2,且夹杂物尺寸较大,使得带钢纵向与横向延伸率明显偏低,带钢制盖时开裂几率大幅增加,无法完全满足易开盖所需的成形性能。
5. 对比例2中,热轧卷取温度为580℃,其他化学成分与工艺参数类似于实施例1,但对比例2所得镀锡板成品的横向延伸率远低于纵向延伸率,原因为卷取温度低于600℃时,带钢会形成带状组织(如图2),使得纵向性能明显优于横向性能,带钢呈各向异性。
6. 由图1可知,采用转炉冶炼-RH精炼-连铸工艺,夹杂物主要为氧化铝类。
7. 由图2可知,热轧卷取温度采用580℃时,带钢会产生带状组织,使得带钢的力学性能会呈各向异性,即沿带状组织方向性能明显优于垂直于带状组织方向的性能。
8. 由图3-图4可知,热轧卷取温度采用600~660℃时,带钢不会产生带状组织,使得带钢纵向、横向力学性能相近。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
