Description
技术领域
本发明涉及钢板的熔融镀锌和连续退火的兼用处理设备。
背景技术
通常,熔融镀锌钢板和冷轧钢板分别由不同的生产线(处理设备)制造。在此,熔融镀锌钢板是指在冷轧之后实施熔融镀锌而成为产品的钢板,冷轧钢板是指在冷轧之后不实施熔融镀锌而成为产品的钢板。
然而,在熔融镀锌钢板制造线和冷轧钢板制造线中,在熔融镀锌钢板制造线具有熔融镀锌设备,除了在冷轧钢板制造线没有熔融镀锌设备的情况以外,设备的结构酷似,因此希望通过一条生产线(兼用处理设备)来制造熔融镀锌钢板和冷轧钢板。
但是,为了实现这种情况,需要应对以下的问题。
即,在制造熔融镀锌钢板时,只要利用连续退火炉对钢板进行了退火之后,向与连续退火炉直接连结的熔融镀锌设备引导而通过实施熔融镀锌的道次即可,但是在制造冷轧钢板时,在利用连续退火炉对钢板进行了退火之后,需要切换道次,以通过避开熔融镀锌设备的道次。
此外,在避开熔融镀锌设备时,若将钢板在保持高温的状态下与大气接触,则钢板被氧化,表面外观或化学转化处理性发生劣化的情况成为问题。针对该钢板发生氧化的问题,虽然也考虑了配置酸洗设备来去除氧化膜的方法,但是存在设备费高涨的问题。
因此,为了应对这样的问题,提出了以下那样的技术。
首先,在专利文献1中提出了如下的方法:在避开熔融镀锌设备时,使喷口伸缩、倾斜移动而避开镀锌锅,直接向升降辊引导。
而且,在专利文献2、专利文献3中提出了如下的方法:在避开熔融镀锌设备时,设置旁通炉,不使钢板与大气接触,而向下一设备(水淬设备)引导。

发明内容
发明要解决的课题
然而,在专利文献1记载的方法的情况下,能够缩短道次的切换时间,避开镀锌锅,但是由于在喷口的输出侧不存在密封装置,因此大气向喷口内流入,钢板氧化的问题无法解决。
而且,在专利文献2、专利文献3记载的方法的情况下,旁通炉的新设或已存设备(合金化炉等)的移设等花费巨额的设备费的情况、给熔融镀锌钢板的品质造成影响的情况成为问题。
本发明鉴于上述那样的情况而作出,其目的在于作为钢板的熔融镀锌和连续退火的兼用处理设备,提供一种不需要高涨的设备费而能够以良好的品质制造熔融镀锌钢板和冷轧钢板的钢板的熔融镀锌和连续退火的兼用处理设备。
用于解决课题的方案
为了解决上述课题,本发明具有以下的特征。
[1]一种钢板的熔融镀锌和连续退火的兼用处理设备,其中,具备连续退火炉和熔融镀锌设备,设置有将由连续退火炉退火后的钢板向熔融镀锌设备引导的道次和使由连续退火炉退火后的钢板避开熔融镀锌设备的道次,并且在连续退火炉的出口设置有密封装置,所述密封装置用于防止大气从避开熔融镀锌设备的道次向连续退火炉侵入。
[2]根据所述[1]记载的钢板的熔融镀锌和连续退火的兼用处理设备,其中,所述密封装置的装置内成为氮气气氛。

[5]根据所述[1]~[4]中任一项记载的钢板的熔融镀锌和连续退火的兼用处理设备,其中,连续退火炉的冷却带的气氛氧浓度为90体积ppm以下,连续退火炉的冷却带输出侧的钢板的温度为168℃以下。
[6]一种熔融镀锌钢板和冷轧钢板的兼用制造方法,使用所述[1]~[5]中任一项记载的钢板的熔融镀锌和连续退火的兼用处理设备,分别制造熔融镀锌钢板和冷轧钢板。
发明效果
在本发明中,作为钢板的熔融镀锌与连续退火的兼用处理设备,不需要高涨的设备费,能够以良好的品质制造熔融镀锌钢板和冷轧钢板。
附图说明
图1是表示本发明的一实施方式的图。
图2是图1的局部放大图。
图3是用于表示本发明的一实施方式的连续退火炉的作业条件的图。
图4是用于表示本发明的一实施方式的密封装置的作业条件的图。
图5是表示本发明的一实施方式的压力分布的图。
具体实施方式
基于附图,说明本发明的一实施方式。需要说明的是,本发明没有限定为以下的一实施方式。
图1是表示本发明的一实施方式的钢板的熔融镀锌和连续退火的兼用处理设备(以下,也仅称为“兼用处理设备”)的图,图2是图1的局部放大图。
如图1、图2所示,本实施方式的兼用处理设备具备连续退火炉10(无氧化炉11、加热带12、保持带13、冷却带14)、与连续退火炉10直接连结的熔融镀锌设备20(镀锌锅21、导辊22)、合金化炉30。
此外,设定有:将通过连续退火炉10退火后的钢板1经由向下转向辊41而向熔融镀锌设备20引导,在实施了熔融镀锌之后,经由向上转向辊42到达合金化炉30的道次(熔融镀锌钢板制造用道次)1A;及通过连续退火炉10退火后的钢板1避开熔融镀锌设备,经由向上转向辊42而到达合金化炉30的道次(冷轧钢板制造用道次)1B,并且设置对熔融镀锌钢板制造用道次1A与冷轧钢板制造用道次1B进行切换的道次切换部40。
而且,在本实施方式中,在连续退火炉10的出口设置密封装置50,该密封装置50用于防止大气从避开熔融镀锌设备的道次(冷轧钢板制造用道次)1B向连续退火炉10侵入。
该密封装置50成为紧凑的双层密封结构,作为第一层密封,从N2气体喷嘴51向密封装置50内吹入氮气(N2气体),将密封装置50内形成为氮气气氛。而且,作为第二层密封,在密封装置50的出口部具备密封辊55。
需要说明的是,在将密封装置50内形成为氮气气氛时,优选使密封装置50内的氧浓度成为90体积ppm以下。而且,也可能会混入30体积%以下的氢或氩。
接下来,叙述本实施方式的兼用处理设备的作业条件。
首先,图3中,作为连续退火炉10的作业条件,示出研究了冷却带14的气氛氧浓度(冷却带氧浓度)和冷却带14输出侧的钢板温度(冷却带输出侧板温度)的结果。如图3所示可知,在区域A(冷却带氧浓度为0~90体积ppm且冷却带输出侧板温度为0~168℃的区域)中,钢板即使与大气接触也不会发生氧化(○记号),相对于此,在区域B(冷却带氧浓度超过90体积ppm的区域)、区域C(冷却带输出侧板温度超过168℃的区域)中,钢板与大气接触时会发生氧化(□记号)。
因此,作为密封装置50的作业条件,设为能够稳定地确保上述的冷却带氧浓度为90体积ppm以下且冷却带输出侧板温度为168℃以下这样的条件。即,密封装置50内的压力高于连续退火炉10的炉内压力及大气压,由此,避免大气向连续退火炉10内流入,并且避免连续退火炉10内的氢气向大气泄漏。
图4是作为密封装置50的具体的作业条件,示出密封装置50内的压力(密封装置内压力)与从N2气体喷嘴51向密封装置50内吹入的氮气的流量(N2流量)的关系。基于图4,将N2流量设定为115Nm3/h以上,以使密封装置内压力成为连续退火炉10内的最大压力(最大炉内压力=8.2mmH2O)以上。而且,通过实现密封辊55间的间隙的狭小化,来实现密封装置内压力的保持。
此外,图5中示出用于测定冷却带14的压力的冷却带压力测定口62和用于测定密封装置50内的压力的密封装置内压力测定口61的位置,并且示出冷却带14和密封装置50内的压力分布。
需要说明的是,如图2所示,若连续退火炉10内的氢向密封装置50泄漏时,为了防止氢的燃烧引起的损害,在密封装置50设置辉光加热器58,并且使用难燃性的高硅氧玻璃纤维作为密封帘52的材质。而且,在密封帘52的下方设置难燃性的硅纤维59。此外,在密封装置50设置紧急用N2气体喷嘴53,在冷却带14安装扩散阀45。
这样,在本实施方式中,在退火炉10的冷却带14,以钢板1即使与大气接触也不会氧化的作业条件(冷却带氧浓度90体积ppm以下,冷却带输出侧板温度168℃以下)进行冷却,并且以能够稳定地保持该作业条件的方式在冷轧钢板制造用道次1B上的退火炉10输出侧设置紧凑的密封装置20,由此能提高退火炉10的机密性,从而防止钢板1的氧化。
因此,通过使用这样的钢板的熔融镀锌和连续退火的兼用处理设备,不需要高涨的设备费,能够以良好的品质分别制造熔融镀锌钢板和冷轧钢板。
