Description

柱塞式层流冷却装置 技术领域
本发明涉及一种冶金领域的热轧层流冷却装置， 尤其涉及一种适用于冶金轧 钢生产线的层流宽度可调的冷却装置。 背景技术
钢铁企业的热轧连轧机生产线都要使用到层流冷却装置， 其主要功能就是将 精轧出口的带钢， 根据卷取设定的目标温度进行快速冷却， 以保证带钢的产品性 能。
以宝钢 2050热轧厂为例， 其层流冷却装置共有 76组冷却集管 （对应上下为一 组） 。 其中前 68组为主冷段， 后 8组为精冷段。 一般分为若干个冷却区， 每个冷却 区都有各自的主冷段和精冷段的冷却区串接而成， 冷却区的主冷段又由若干组强 冷集管组和若干组主冷集管组构成。 层冷模型在计算所需打开集管阀组时， 按照 主冷段从前往后， 精冷段从后往前规则进行设定。 因此， 根据终轧温度到卷取温 度的设定温降， 主冷段的前 4组以及精冷段的后 4组在每次设定都是需要打开的， 因此基本上处于常开状态； 每组集管的位置 （距精轧最后机架） 在基础自动化控 制中都有数据， 另外基础自动化对于带钢在层流辊道上的位置都需要进行跟踪。 其冷却控制如下：
首先， 过程机根据设定的终轧温度和卷取温度， 通过层冷模型计算， 确定主 冷段和精冷段冷却集管的打开组数， 并下发指令给精轧基础自动化对水阀进行控 制。
其次， 当带钢出精轧最后机架由精轧后测温仪测出带钢实际的终轧温度后， 再对冷却集管的打开组数进行相应的调节。
最后， 当层冷后的卷取测温仪测出带钢的实际卷取温度后， 根据设定的卷取 目标值动态对层流冷却集管打开组数进行调节， 以保证带钢的卷取温度在设定范 围内。 每个阀组的冷却水量可控制带钢温度为 5度。
热轧带钢板形一直是用户们特别关注的质量问题， 板形质量优劣直接影响产 品的使用， 尤其是近年来随着钢铁工业的迅猛发展， 带钢产品应用领域不断拓 展， 用户对其板形质量的要求也日益提高。 热轧生产线不断发展， 生产品种、 规格逐渐扩大， 目前的产品结构与以前已 经截然不同， 以前以普碳钢为主， 目前主要生产微合金钢和碳锰钢。 现有的层流 冷却系统， 随着轧线轧制规格的不断拓展和用户对产品质量要求的不断提高， 已 经不能满足部分钢种生产的需要， 尤其是一些含有合金元素的强度钢 （如：
BS600、 BS700、 B510L、 S45C、 SS400等） 。 这些强度钢在经过层流冷却区域以 后， 由于现有的层流冷却系统存在着水压不稳、 水流分布不均匀等问题造成带钢 的冷却不均， 从而导致带钢出现一系列板形质量问题， 在轧线生产过程中容易发 现带钢由于冷却不均造成的 C翘， 和宽度方向冷却不均造成的板形变化,尤其边部 温度降低较大会在后续冷却过程中产生带来双边浪趋势的内应力， 给带钢的板 形、 机械性能、 温度及相变在宽度方向的均匀性都会带来很大影响。
层流冷却对板形影响的主要是通过相变、 应力和导热性。 在国内外比较有效 的措施就是边部遮挡装置， 而且效果比较明显。 目前， 国内主要是德国 SMS-DMG 的 EDGER MASKING边部遮挡技术的应用， 通过油缸控制连杆机构来调整层流冷 却上喷冷却水宽度的遮挡板。 例如邯钢热轧 CSP生产线 2003年二线建设工程中引 进的 SMS公司边部遮挡技术的应用。
日本三菱重工业株式会社 2002年 12月 17日公开的专利 《带材冷却装置》 专利 号 JP2002361316A, 其方案是在层流冷却时将带钢边部的冷却水通过储水槽收集来 提高带钢边部的温度， 储水槽收集的冷却水则通过专用排水管排出。 显而易见， 这种技术存在一个的缺点： 在生产较窄带钢时， 大量冷却水白白浪费。
日本川崎水岛厂早在 20世纪 80年代就开展了关于层流边部遮挡对改善板形的 研究， 川崎制铁有限公司在中国申请专利 《金属带材的冷却方法和装置》 （申请 公开日 1987.12.16， 专利公开号 CN87100594 ) ， 其层流冷却装置采用由一对限定 狭缝的平板部件组成的层流喷管,冷却水流过此狭缝形成一冷却水屏栅， 为调节该 喷管内的通道区域,该层流喷管的平板部件至少有一个在垂直于冷却水流动的方向 上可以变形,至少有一个平板较好地响应冷却水压力,引起通道区域变化,从而调节 冷却水通道区域。 此方法采用对层流冷却集管边部遮挡的方法， 对带钢边部温度 降低较大问题提供了一个解决办法， 但该方法也存在不足之处， 显而易见， 这种 现有技术的缺点是： 在生产较窄带钢时， 大量冷却水白白浪费， 不利于生产资源 的节约。 另外， 现有技术提高带钢边部温度的方法， 其原理都是采用对层流冷却集 管边部进行一定宽度的遮挡， 对带钢边部温度降低较大问题提供了一个解决办 法， 但该方法也存在共同的不足之处：
1.浪费资源： 在生产较窄带钢时， 被遮挡的大量冷却水白白浪费， 不利于生 产资源的节约， 消耗电费、 增加水处理成本。
2.影响环境： 层流冷却遮挡板向两侧分流的冷却水， 对电机和层流辊道轴承 座 带来不利影响， 虽然采取了导流板， 但仍然在一定程度上劣化了该处的环境。
3.故障率高： 带钢跑偏时， 两侧边部遮挡不能够同步调整， 当带钢跑偏较大 时， 一侧的边部遮挡就无法发挥遮挡作用， 导致带钢跑偏时不能正常使用。
4.机构卡死： 层流冷却环境恶劣， 经常发生连杆机构卡死故障。
5.精度不高： 该连杆机构的遮挡板易变形， 往往造成两侧遮挡精度不符合要 求。
6.堆钢易损： 层流冷却段发生堆钢故障时， 连杆机构及遮挡板易造成变形或 损坏。
7.无下喷遮挡： 该连杆机构无法应用于下喷层流冷却， 无下喷层流遮挡装 置， 带钢上下表面冷却不均匀， 也会导致一定的带钢边部浪形。
因此， 申请人希望发明另外一种层流冷却装置， 该装置能够根据带钢不同宽 度的冷却工艺要求， 对应建立相应于带材通道宽度的缝隙层流， 实现层流冷却区 域在宽度上的相应变化,从而调节冷却水在通道宽度方向上的区域， 以减少带钢边 部的温降， 确保带钢的板形、 机械性能、 温度及相变在宽度方向的均匀性。 该装 置和控制方法与现有的边部遮挡技术不同， 能够大大节约冷却水的用量。 发明内容
本发明的目的是针对现有层流冷却系统存在带钢宽度方向冷却分布不均匀的 现象， 提供一种柱塞式层流冷却装置， 该装置能够利用较少的冷却水， 根据带钢 不同宽度的冷却工艺要求， 对应建立相应于带材通道宽度的缝隙层流， 实现根据 层流冷却区域在宽度上的相应变化，调节冷却水在通道宽度方向上的区域， 用以减 少带钢边部的温降， 确保带钢的板形、 机械性能、 温度及相变在宽度方向的均匀 性。

实施例 6
本实施例中的下喷装置包括若干下喷喷管装置， 其中每一个下喷喷管装置的 结构如图 21和图 22所示： 下喷集管 22沿垂直带钢运行方向固定设置； 若干下喷喷 管 23沿下喷集管 22的轴向方向均布于其上， 下喷喷管 23与下喷集管 22导通， 两个 下喷柱塞管 24， 分别固定设置于下喷集管 22的左右两端上方， 两个下喷柱塞管 24 分别贯穿均布于下喷集管 22两端的若干下喷喷管 23， 将下喷喷管 23分为上喷嘴和 下喷管两部分， 下喷柱塞管 24通过设于其管壁上的若干通孔与下喷喷管 23的上喷 嘴和下喷管导通， 两个下喷柱塞 25， 分别设于两下喷柱塞管 24内， 下喷柱塞 25的 外径与下喷柱塞管 24的内径匹配， 反向螺纹丝杆 26通过轴承座平行设于下喷集管 22的上方， 反向螺纹丝杆 26两端连接有两个异型螺母 27， 可沿反向螺纹丝杆 26的 轴向方向相向或反向运动； 两个 U型罩 28与下喷柱塞 25平行设置， U型罩 28的开口 朝下， 罩于下喷喷管 23的上方， 由于下喷装置距离带钢很近， 容易被高温带钢炙 烤而发生故障外， 因此 U型罩 28能够为下喷柱塞管 24和下喷喷管 23提供保护作 用。 U型罩 28的外端与下喷柱塞 24的外端通过连接板 29和螺钉实现固定连接。 此 外， U型罩 28的前侧板下端通过开有对穿孔的连接底座与异型螺母 27实现固定连 接， U型罩 28的后侧板下端通过螺钉固定连接有圆柱形 U型罩导向块 30， 下喷柱塞 管 24的外壁上固定设有圆柱形 U型罩导向槽 31， U型罩导向块 30与 U型罩导向槽 31 配合设置， 实现 U型罩导向块 30在 U型罩导向槽 31内的轴向滑动， 进而实现对 U型 罩 28的导向作用。 下喷驱动电机 32与各反向螺纹丝杆 26对应连接， 驱动其转动。
该装置的工作过程为： 下喷驱动电机 32驱动反向螺纹丝杆 26转动， 转动的反 向螺纹丝杆 26带动其两端的异型螺母 27沿直线方向相向或反向运动， 异型螺母 27 带动与其固定连接的 U型罩 28做直线运动， 由于下喷柱塞 25与 U型罩 28对应固定连 接， 故下喷柱塞 25也在下喷柱塞管 24内滑动， 其运动与 U型罩 28是同步的。 下喷 柱塞 25通过阻断下喷柱塞管 24管壁上的通孔个数， 实现对从而对下喷喷管内水流 的截留， 进而实现冷却水量在宽度方向的调节。
本实施例仅提供了采用一台下喷驱动电机驱动反向螺纹丝杆转动的技术方 案， 除此方案外还可采用两侧下喷驱动电机分别驱动两侧各自的螺纹丝杆转动， 可以在带钢跑偏时实现单侧自由控制来适应位置的变化要求， 又可以大大缩短丝 杆的长度， 避免丝杆过长易变形而导致故障发生。

当下喷驱动电机 32转动时， 驱动套于其输出轴上的主动链轮 65转动， 主动链 轮 65通过主动链条 66带动与其连接的从动链轮 63转动， 从动链轮 63再通过从动链 条 64实现所有双排从动链轮 63同步转动， 进而带动下喷装置中的各反向螺纹丝杆 同步转动， 实现一台电机对所有下喷装置的驱动。
本实施例仅提供了采用一台下喷驱动电机驱动反向螺纹丝杆转动的技术方 案， 除此方案外还可采用两侧下喷驱动电机分别驱动两侧各自的螺纹丝杆转动， 可以在带钢跑偏时实现单侧自由控制来适应位置的变化要求， 又可以大大缩短丝 杆的长度， 避免丝杆过长易变形而导致故障发生。
综上可知， 本发明所述的柱塞式层流冷却装置能够通过多种实施方式， 根据 带钢不同宽度的冷却工艺要求， 对应建立相应于带材通道宽度的缝隙层流， 实现 层流冷却区域在宽度上的相应变化，从而调节冷却水在通道宽度方向上的区域， 减 少带钢边部的温降， 确保带钢的板形、 机械性能、 温度及相变在宽度方向的均匀 性； 另外， 本发明技术与现有的边部遮挡技术不同， 在达到同样效果的同时， 还 能够避免冷却水资源的浪费； 此外， 本发明通过对驱动装置的配置， 还实现了对 设备资源的节约利用。 最后应当说明的是： 以上实施例仅用以说明本发明的技术方案而非对其限 制； 尽管参照较佳实施例对本发明进行了详细的说明， 所属领域的普通技术人员 应当理解： 依然可以对本发明的具体实施方式进行修改或者对部分技术特征进行 等同替换； 而不脱离本发明技术方案的精神， 其均应涵盖在本发明请求保护的技 术方案范围当中。
