Description

不锈钢卷焊接引带的方法及系统 本申请要求于 2007 年 3 月 28 日提交中国专利局、 申请号为 200710061655.X,发明名称为"一种不锈钢卷焊接引带的方法"的中国专利申请 的优先权， 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及不锈钢卷引带焊接技术，具体涉及一种不锈钢卷焊接引带的方 法及系统。
背景技术
在不锈钢带钢的冷轧过程中， 一般采用单机架可逆式冷轧机进行轧制， 由 于两侧卷取机到轧辊的中心距离较大，两侧共造成 14m— 16m的不锈钢原料带 钢不能轧制， 严重影响成材率， 为了充分利用这部分原料， 提高成材率， 一般 在不锈钢原料带两端焊接小于母材厚度的引带，提高可轧制长度，提高不锈钢 成材率。
现有的不锈钢卷焊接引带的方法有两种，一种是采用完整的准备机在黑卷
(未经过退火与酸洗的不锈钢卷）上焊接引带， 该方法的步骤依次是： 开卷、 切头、 焊接引带、 整卷开卷到卷取机、 尾部切头与焊接引带， 实现两端焊接引 带， 这种方法必须将整卷开卷到卷取机， 再进行尾部引带的焊接， 缺点是需要 完整的准备机组， 投资大， 在加引带时需要整卷开卷， 占用设备时间长， 设备 利用率低， 容易损伤钢卷表面， 由于在黑卷上直接焊接引带， 导致在以后的原 料退火酸洗线生产中张力按制困难，容易产生炉内断带等严重后果， 同时由于 引带本身也随钢卷通过热加生产线， 占用了机组能力，影响原料退火酸洗线的 产能， 另外， 由于需要与不锈钢一起通过生产线， 引带必须用 300系列奥氏体 不锈钢。 另一种方法是在简易准备机组（只有卷取机、 焊接机没有 «又机）上 加头部引带， 该方法的步骤依次是： 开卷、切头、焊接引带、钢卷退回卷取机， 这种方法虽然设备投资小， 不需要整卷开卷， 也可以在白卷（经过退火与酸洗 的钢卷）焊接引带， 但只能在钢卷的一端加引带， 另一端不能加引带， 不能完 全满足不锈钢生产的需要， 在轧制的过程中， 原材料消耗大。
发明内容 为了克服现有不锈钢卷焊接引带的方法的上述不足，本发明提供一种不锈 钢卷焊接引带的方法及系统， 以降低设备投资， 提高设备利用率。
本发明提供的不锈钢卷焊接引带的方法包括以下步骤：
在原料退火酸洗线尾部焊接带钢头部引带；
将所述头部引带接入卷取机， «又焊接着所述引带的带钢， 成不锈钢卷； 传送所述钢卷到开卷机；
开卷机开卷打开所述钢卷外圏；
焊接外圏引带；
开卷机回卷，将所述外圏引带与钢卷盘卷在一起。上述的不锈钢卷焊接引 带的方法， 引带的材料可用与钢卷材料相同的不锈钢板，也可用与钢卷材料不 同的不锈钢板， 还可用碳素钢板引带或镀锌钢板引带及合金钢钢板引带。
本发明实施例提供的不锈钢卷焊接引带的系统， 包括由开卷机、第一焊接 机组成的准备机组， 其中， 所述开卷机开卷打开钢卷外圏， 第一焊接机焊接外 圏引带， 并在焊接完成后， 由所述开卷机回卷， 将所述外圏引带与钢卷盘卷在 一起； 还包括：
设置在原料退火酸洗线尾部的第二焊接机， 用于焊接带钢头部引带； 卷取机， 用于将所述头部引带接入， 并 «又焊接着所述头部引带的带钢成 钢卷；
传送装置， 用于将所述钢卷传送到所述开卷机。
所述系统还可进一步包括：挖边机， 用于对所述第二焊接机焊接后的所述 带钢和所述头部引带之间的焊缝进行挖边处理。
本发明在原料退火酸洗线尾部增加了一台焊接机，进行带钢头部引带的焊 接， 与原料退火酸洗线配套增加了一台简易准备机组，进行带钢尾部引带的焊 接， 实现了白卷两端焊接引带的功能。 这样， 解决了目前普遍采用的焊接引带 的方式所带来的影响原料退火酸洗线产能的问题； 原料退火酸洗线线力控制， 特别是炉内张力控制困难，容易引起炉内断带的问题； 为焊接引带多一次整卷 开卷所产生的表面损伤问题。
本不锈钢卷焊接引带的方法与现有不锈钢卷焊接引带的方法相比，具有下 述的有益效果： 1 ) 采用简易准备机组与原料退火酸洗线设备相配合， 实现对处理后的 白卷焊接两端引带， 解决了在黑卷两端焊接引带投资大， 效率低， 多一次整卷 开卷造成的带钢表面损伤， 同时， 可充分发挥原料退火酸洗线的产能， 也从根 本上消除了由于在黑卷焊接引带造成的原料退火酸洗线张力控制困难，在原料 退火酸洗线炉内容易断带的严重问题；
2 )与现有简易准备机组加引带的方法相比， 实现了在白卷两端均加上引 带， 在后继的加工中， 减少了对不锈钢母材的消耗量；
3 )由于在原料退火酸洗线处理后的白带加引带， 引带不再与不锈钢一起 通过原料退火酸洗线， 减小了不锈钢引带的在原料退火酸洗线的消耗；
4 )由于利用了原料退火酸洗线的卷取等设备， 与为了达到同样功能配置 的设备相比， 减少了准备机组的部件设置， 大幅度降低了投资资金。
5 ) 由于在原料退火酸洗线处理后的白带加引带， 引带不再与不锈钢一起 通过原料退火酸洗线， 因此本发明可实现不锈钢生产选用碳素钢引带、镀锌钢 板引带及合金钢引带。
本不锈钢卷焊接引带的方法，提高了原料退火酸洗线的产能， 消除了引带 对原料退火酸洗线控制的影响及由此导致的炉内断带的危险，大幅度减小了随 后工序加工及引带通过原料退火酸洗线的不锈钢材料损耗。 同时， 由于只用了 一台简易准备机组的配合就实现了白卷两端焊接引带， 有效地减少了设备投 资， 可选用碳素钢引带、镀锌钢板引带及合金钢板引带， 突破了必须使用不锈 钢引带的限制。

需要说明的是， 在上述焊接过程中：
a. 由于在原料退火酸洗线尾部进行引带焊接操作， 需要占用 5— 6分钟的 时间， 在这种情况下， 原料退火酸洗线的工艺段不准停车等待， 因此为了解决 原料退火酸洗线工艺段不停车问题，将原料退火酸洗线尾部活套增加，使其再 增加 5— 6分钟的 160m— 210m (一般长 200 m )长的带钢储量。 为此， 可以设 置两层活套，增加一个活套小车及卷扬系统及相应的张力辊组成的张力控制系 统， 同时采用两个活套小车同步控制。 b. 焊接后的带钢需要挖边处理， 因此原料退火酸洗线尾部焊接机配套设 置一台挖边机， 简易准备机组的焊接机配套设置一台挖边机。
C. 简易准备机组的开卷机需要完成开卷、 卷取两个功能， 其节奏需要与 原料退火酸洗线卸卷节奏匹配，所以可以按照原料退火酸洗线能力及焊接引带 的卸卷节奏， 配合简易准备机组的节奏，在原料退火酸洗线与简易准备机组之 间， 增加钢卷存放鞍座作为緩冲位。
完成后转入下一道工序。

上述实施例所用的主要设备的排列参考图， 参见图 9、 图 10。
本发明的简易准备机组主要由开卷机、矫直机、挖边机与焊接机组成， 与 原有的准备机组相比，开卷机可以回卷而卷取钢带，因此不需要钢卷整卷开卷， 并减少了卷取机的设置。
原有的可实现不锈钢卷两端焊接引带的简易准备机组主要由开卷机、矫直 机、 挖边机、 焊接机与卷取机组成。
图 9中 «又机 24作为备用设备。
由上述各实施例可见， 本发明在原料退火酸洗线尾部增加了一台焊接机， 进行带钢头部引带的焊接， 与原料退火酸洗线配套增加了一台简易准备机组， 进行带钢尾部引带的焊接， 实现了白卷（经过退火酸洗后的不锈钢卷）两端焊 接引带的功能。这样，解决了目前普遍采用的焊接引带的方式所带来的影响原 料退火酸洗线产能的问题； 原料退火酸洗线线力控制，特别是炉内张力控制困 难，容易引起炉内断带的问题； 为焊接引带多一次整卷开卷所产生的表面损伤 问题。
