Description

一种多条钢带连续热浸镀锌生产方法
技术领域
本发明涉及钢带表面镀层生产工艺技术领域,特别是一种多条钢带连续热浸镀锌生产方法。
背景技术
热浸镀锌(锌合金)钢带以其优异的耐腐蚀性和良好的加工成型性,被广泛应用于国民经济的各个行业。钢带热浸镀锌生产工艺是将冷轧带钢连续通过充满氢氮还原性气氛的退火炉内,在实现退火热处理的同时,通过氢气还原使钢带表面的氧化铁膜层被充分还原成活性的纯铁层,然后带钢在保护性气氛中直接浸入熔融的锌(锌合金)液中,使其表面镀上一层锌(锌合金)层。
现有带钢连续热浸镀锌生产技术一条生产机组同时只能生产一条带钢。受冷轧带钢规格和镀锌机组生产规模效益的制约,现有机组生产镀锌带钢的最小宽度在300mm左右。目前市场上所需宽度在300mm以下的镀锌钢带都是通过宽的镀锌钢带分条而获得的。经过分条得到窄钢带,其两边切口部分没有镀锌层,露出了钢基体,在后续长期使用过程中,切口部分易发生腐蚀。
发明内容
本发明的目的是提供一种可以实现多条带钢带同时连续热浸镀锌的生产工艺技术,以实现两条及两条以上多条带钢同时热浸镀锌的目的,这样一来,既可以提高窄带钢生产机组的产能,也可以为市场提供无边部切口的窄镀锌带钢。
按照本发明提供的技术方案,一种多条钢带连续热浸镀锌生产方法,其特征在于,采用以下工艺步骤:
(1)开卷准备:
冷轧原料钢卷送到开卷阶段开卷机上,开卷机夹住钢卷旋转,将钢带头部送入生产机组,钢带头部在准备阶段与前一卷钢带的尾部焊接在一起,以确保机组连续运行;
(2)分条精整:
钢带从开卷准备阶段出来后进入分条精整阶段,在此处钢带将根据用户需求被分切成多条相关要求宽度的窄条钢带,并对每条钢带的切边进行精整,去除边部毛刺,避免毛刺对后镀锌的工序的影响;
(3)还原退火:
分条精整后的各条带钢通过张力辊和转向辊等设备的传送,将带钢送入还原退火炉内,在此处带钢将根据热处理制度加热到要求的温度,并在含有氢气的保护性气氛中完成表面还原处理,从而在带钢表面形成活性的纯铁层,为后续热浸镀锌做好准备;
(4)热浸镀锌:
带钢在还原退火炉内完成退火及还原工艺后直接进入热浸镀锌段的锌锅中,锌锅内充满了熔融锌镀液;钢带从锌锅出来后,其表面将形成一层镀锌层,锌锅上布置有镀层厚度控制设备,通过镀层厚度控制设备的控制,钢带表面将获得用户要求厚度的均匀镀锌层;
(5)镀后冷却:
镀锌后的带钢表面温度较高,因此,经过风冷和水淬冷却的镀后冷却工序,将带钢冷却到常温;
(6)后处理:
冷却后的钢带将进入后处理阶段,在此步骤中,钢带将根据用户的要求进行钝化、漆封或涂蜡的后处理;
(7)卷取:
后处理后的带钢进入出口卷取阶段,在这里每条带钢将由一台卷取机卷成成品卷。
进一步地,步骤1中,钢带开卷准备段设置有钢带储存设备,储存设备采用活套,当开卷段焊机停机时,活套内储存的钢带可以满足后续工段连续运行。
进一步地,步骤4中镀层厚度控制设备为气刀。
本发明与已有技术相比具有以下优点:
1、采用在线分条,可根据用户需求直接生产出所要求宽度的镀锌带钢;
2、采用带槽多辊并联张力辊和转向辊驱动传输带钢,每根带钢由一个辊传送,既可以有效防止带钢在机组上运行时相互干扰,也可以解决由于同板差带来的分条后每条带钢长度不一致从而导致带钢张力不一致的问题;
3、采用复绕式卷取机,实现每条带钢单独卷取,可实现大卷卷取,提高机组生产效率。
附图说明
图1为本发明的工艺流程图。
具体实施方式
下面本发明将结合附图中的实施例作进一步描述:
下面将对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明的一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
一种多条钢带连续热浸镀锌生产方法,此法也是应用于条钢带连续热浸镀锌合金,具体采用以下工艺步骤:
如图1所示,其中1-7的标号,分别代表7个步骤对应的钢带所经历的阶段。
(1)开卷准备:
冷轧原料钢卷送到开卷阶段的开卷机上,开卷机夹住钢卷旋转,将钢带头部送入生产机组,钢带头部在准备阶段与前一卷钢带的尾部焊接在一起,以确保机组连续运行;
其中钢带开卷准备阶段设置有钢带储存设备为活套,当开卷阶段焊机停机时,活套内储存的钢带可以满足后续工段连续运行。
(2)分条精整:
钢带从开卷准备段出来后进入分条精整段,在此处钢带将根据用户需求被分切成多条相关要求宽度的窄条钢带,并对每条钢带的切边进行精整,去除边部毛刺,避免毛刺对后镀锌的工序的影响;在此步骤中,原料钢板在这里经过分切变成多条钢带,带钢边部切口会形成毛刺,并不光滑,在后续热浸镀锌过程中,钢带从锌液出来时,边部会带上多余的锌液,形成钢带边部镀层超厚,影响产品质量。
(3)还原退火:
分条精整后的各条带钢通过张力辊和转向辊等设备的传送,将带钢送入还原退火炉内,在此处带钢将根据热处理制度加热到要求的温度,并在含有氢气的保护性气氛中完成表面还原处理,从而在带钢表面形成活性的纯铁层,为后续热浸镀锌做好准备;
在此处,采用带槽多辊并联张力辊和转向辊驱动传输带钢,每根带钢由一个辊传送,既可以有效防止带钢在机组上运行时相互干扰,也可以解决由于同板差带来的分条后每条带钢长度不一致从而导致带钢张力不一致的问题;
(4)热浸镀锌:
带钢在还原退火炉内完成退火及还原工艺后直接进入热浸镀锌段的锌锅中,锌锅内充满了熔融锌镀液;钢带从锌锅出来后,其表面将形成一层镀锌层,锌锅上布置有镀层厚度控制设备,通过镀层厚度控制设备的控制,钢带表面将获得用户要求厚度的均匀镀锌层;镀层厚度控制设备为气刀。
镀锌时,钢板表面活性的纯铁层与锌液发生反应,形成合金扩散层,该扩散层在基体与纯锌层之间,确保了镀层的附着性。
(5)镀后冷却:
镀锌后的带钢表面温度较高,因此,经过风冷和水淬冷却的镀后冷却工序,将带钢冷却到常温;
(6)后处理:
冷却后的钢带将进入后处理阶段,在此步骤中,钢带将根据用户的要求进行钝化、漆封或涂蜡的后处理;
钝化和漆封的目的是在钢带表面涂上一层保护膜,防止镀锌后钢带在运输过程中生白锈;涂蜡的目的是在钢带表面图上一层蜡作为润滑层。
(7)卷取:
后处理后的带钢进入出口卷取阶段,在这里每条带钢将由一台卷取机卷成成品卷;本步骤中,采用复绕式卷取机,实现每条带钢单独卷取,可实现大卷的卷取。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书内容所作的等效结构或等效流程变换,或直接或间接运用在其它相关的技术领域,均同理包括在本发明的专利保护范围内。
