Description

连铸机结晶器及其温度检测装置
技术领域
本发明涉及连铸自动化控制领域， 尤其涉及一种连铸机结晶器及其 温度检测装置。 发明背景
在连铸工艺的生产过程中， 钢液从大包通过长水口保护套管流入中 间包， 再经水口进入结晶器， 由于结晶器保护渣融渣不良、 拉坯速度过 快或其它原因导致初生坯壳与结晶器铜板接触， 形成粘结而产生漏钢， 造成巨大的经济损失。
在连铸机正常生产时， 初生坯壳不与结晶器铜板直接接触， 中间隔 着保护渣液， 结晶器铜板温度稳定。 粘结时， 初生坯壳与结晶器铜板直 接接触， 结晶器铜板温度迅速上升。 因此， 可以通过对结晶器铜板温度 变化的检测， 对漏钢进行预 >¾和处理， 避免漏钢事故的产生。
通常在温度检测过程中会受到水或其他因素的影响， 导致检测的温 度不准确。 目前， 炼钢厂连铸生产中所使用的漏钢预报温度传感器通常 采用碰焊结构， 直接将温度传感器的热电偶丝或热电阻丝碰焊到连铸机 结晶器铜板上， 但这种方式不易拆卸， 而且热电偶丝的测温误差柏松分 布也不好控制， 热电偶丝本身的误差也无法校准。 发明内容

另外， 本发明的实施例提供了一种连铸机结晶器， 构成连铸机结晶 器的各侧壁分别包括铜板和位于铜板外侧的水箱， 其中， 至少一侧壁上 设有贯穿水箱的连接至结晶器铜板的根据上述结构的至少一温度检测 装置， 温度检测装置的外套管或内套管螺接于铜板的安装孔中。
其中， 上述水箱的外侧壁上开设有走线槽和汇线槽。
在本发明的实施例温度检测装置中， 设置外套管和内套管， 外套管 与结晶器铜板密封配合， 防止渗水， 内套管的端部形成防水保护部， 对 感温组件的感温部位形成封闭或者密封防水保护。 通过这种设置， 可最 大限度地降低结晶器铜板的渗水的影响。 这样增加了感温组件的使用寿 命， 也提高了温度采集的准确度。
除了上面所描述的目的、特征和优点之外，本发明还有其它的目的、 特征和优点。 下面将参照图， 对本发明的其它的目的、 特征和效果作进 一步详细的说明。 附图简要说明

图 12示出了根据本发明的连铸机结晶器的透视图； 以及 图 13示出了图 12所示连铸机结晶器的另一透视图。 实施本发明的方式
为使本发明的目的、 技术方案和优点更加清楚明白， 以下举具体实 施例并参照附图， 对本发明作进一步详细说明。
图 1 示出了根据本发明第一实施例的温度检测装置。 如图 1 所示， 在连铸机结晶器的铜板 7上设有安装孔 7A, 温度检测装置 螺接于安装孔 7A 中。 在本实施例中， 温度检测装置包括： 外套 管 3 , 其适于连接至结晶器铜板 7上； 内套管 2, 其穿设于外套管 3中， 其一端 2A与结晶器铜板 7相接触， 且为封闭端； 感温组件 1 , 其设置于内套管 2中， 用于检测结晶器铜板 7的温度。 进一步 地， 本实施例中的温度检测装置还包括： 弹性元件 4, 其向内套 管 2偏压， 以便在温度检测装置安装至结晶器铜板 7后、 4氏压在 铜板 7上、 检测铜板 7温度； 螺帽 6 , 其螺接在内套管 2中， 抵 压弹性元件 4, 通过改变螺帽 6 的旋拧长度， 可预定弹性元件 4 的偏压力。
在本实施例中， 外套管 3的端部螺接于铜板 7 中， 外套管 3 上套设有防水垫片 5 , 该防水垫片 5可 ^"闭螺接间隙， 以防止从 螺接间隙处渗水。
在本实施例中， 外套管 3螺接到铜板 7中， 而内套管 2却是 接触到铜板 7的， 内外套管相分离。 因此， 当外套管 3松动或是 外套管 3与铜板密封不好时， 内套管 2在弹性元件 4的压迫力的 作用下， 使内套管 2紧密接触铜板， 形成了第二重密封。 采用这 种结构， 由于外套管 3螺接到铜板 7 , 不易松懈且不容易渗水， 具有较好的固定和密封作用。 即使外套管 3松懈了， 内套管 2在 弹性元件 4的作用力下还是紧贴着铜板 7上。 因此， 如果水从外 套管 3处渗入， 但是由于内套管 2还有封闭端 2A, 水也不会进入 内套管 2中的感温元件 1的测温区， 从而保证了测温的准确' I"生。 而且， 在实际应用中， 外套管 3最多回松 3- 8度， 而实验证明外 在实际应用中， 本实施例的温度检测装置具有很好的密封性， 可 以有效地防止水进入内套管 2中。
相比地， 在传统的安装方式中， 外套管接触到铜板， 热电偶 再穿过外套管并检测铜板的温度， 这样当外套管松懈或是接触处 密封不严时， 那么水就容易从外套管与铜板的接触处渗入， 从而 影响测温的准确<1 "生。
图 2示出了根据本发明第二实施例的温度检测装置， 如图 2 所示， 本实施例与第一实施例不同之处在于： 内套管 2贯穿螺帽 6 , 感温组件 1通过螺接部 1A螺接固定至内套管 2。 感温组件 1 也可以通过其他方式与内套管 2连接， 比如卡口连接等。
图 3示出了根据本发明第三实施例的温度检测装置， 如图 3 所示， 在外套管 3上除了套设有防水垫 5之外， 在外套管的端部 还设有防水垫 10, 该防水垫 10起到双重封闭渗水间隙的作用， 以确保内套管 2与结晶器铜板 7紧贴接触的部位不存在渗水而影 响温度的准确测量。
图 4示出了根据本发明的第四实施例的温度检测装置， 如图 4所示， 内套管 2上设有螺接部 4A, 内套管 2通过螺接部 4A直 接螺接在外套管 3中。 并且外套管 3A内设有台阶面 3A, 内套管 2外壁上设有凸台 2B , 台阶面 3A和凸台 2B之间设有压缩弹簧， 以防止螺纹连接因结晶器的振动而松脱。 图 5示出了图 1-4所示温度检测装置实施例的变型。 在该变 型实施例中， 内套管 2的端部是敞口的， 并且内套管 2的端部与 结晶器铜板 7之间设有密封圏 10, 以实现对内套管 2内的感温组 件的保护。
图 6示出了根据本发明温度检测装置中的感温组件的一种结 构。 如图 6所示， 感温组件 1包括本体 11、 套设于本体 11上的套 管 13、 向套管 13偏压的弹簧 14, 本体 11的靠近末端感温部位设 有挡肩 12, 在本体 11的始端设有螺接部 15 , 信号插座 16电连接 至螺接部 15的信号线上， 该信号插座 16可用于连接外部的信号 插头 17 ,通过设置信号插头和插座，可以实现信号线的快速连接， 操作方便。 另外， 当感温组件出现故障时， 可以快速连接， 这样 可以减少现有连线方式 （将信号线剪断后重新连接） 的弊端， 节 省操作时间， 避免接线操作对工作现场所带来的负面影响。 在其 它实施例中， 感温组件 1上也可以不设置信号插座 16, 而直接引 出信号线。
本体 11的末端感温部位可以由热电偶形成，也可以由热敏电 阻构成。 当感温组件 1通过螺接部 15螺接于内套管 2时， 弹簧 14向套管 13偏压， 这样可以保证本体的末端感温部位始终与内 套管的封闭端 2A热传导良好的接触。
图 7示出了根据本发明温度检测装置中的感温组件的另一种 结构。 该结构的感温组件与图 6所示的感温组件不同之处在于， 该感温组件的本体 11 包括螺接部 15、 扳手部 16和信号插座 17 , 直接螺接于内套管 2中，本体 11的末端感温部位用于感测温度变 化。 为防止外套管 3振动松脱， 可设置弹性垫片以防松脱。 图 8和图 9示出了根据本发明第五实施例的温度检测装置。 如图所示， 温度检测装置贯穿水箱 7，， 其外套管 3的端部抵靠在 结晶器铜板 7的表面 7B , 并且设有密封圏或垫 5 , 用于形成第一 重密封。 结晶器铜板 7上开设有安装孔 7A (例如螺纹孔）， 用于 螺接内套管 2的下端， 内套管 2的端部设有密封圏或垫 10, 用于 形成第二重密封。 外套管 3设有内螺纹， 内套管 2设有外螺纹， 内套管 2螺接在外套管 3中， 内套管 2螺接在结晶器铜板 7上， 此时内套管 2的端部可不封闭， 内套管 2中的感温组件的末端感 温部位可以直接与铜板相接触。
另夕卜， 在水箱 7，外， 内套管 2和外套管 3之间可设置螺旋弹 簧或弹簧垫等防松件， 以防松懈。
根据本实施例，密封圏或垫 5防止水从外套管 3渗入内套管。 即使水从外套管 3渗入内套管 2, 由于内套管 2螺接于结晶器铜 板 7中， 螺接的连接方式本身可以防止水进一步渗入感温组件的 测温区。 并且， 内套管 2的端部设有密 †圏或垫 10, 可以进一步 防止水渗入感温组件的测温区， 从而提高测温的准确性。
图 10和 11 出了根据本发明第六实施例的温度检测装置。 如 图 10和 11所示， 温度检测装置包括： 外套管 3 , 适于穿设结晶 器水箱并与结晶器铜板 7螺接； 内套管 2位于外套管 3中的靠近 结晶器铜板 7的一端， 具有可伸出外套管 3的防水保护端； 感温 组件 1 , 设置于内套管 2中， 感测结晶器铜板 7的温度。 其中， 感温组件 1可以连接到内套管 2上； 或者， 由于本实施例的内套 管 2较短， 感温组件 1也可以连接到外套管 3上。 内套管 2设置 于外套管 3里面， 可以在一定程度上自由伸缩， 内套管 2与外套 管 3之间有弹性元件 4 , 用于外套管 3回松或是没有安装好的情 况下 （如图 11所示）， 可以通过弹性元件 4的紧迫力使内套管 2 紧紧的压在结晶器铜板 7上。 内套管 2的防水保护端可以是封闭， 也可以是开孔的。 当防水保护端开孔时， 其可以包括设置于其端 部的密封圏 10, 以便于在结晶器铜板 7底部形成密封。 内套管 2 周围也可以设置密 †圏 25。 如果水从螺纹处渗入， 则密 †圏 25 可以防止水从内套管 2与外套管 3的间隙处回流直到感温组件 1 的测温区。 内套管 2的端部可以设有凹槽， 用于设置密封圏 10。 套管 2的周围也可以设有凹槽， 用于设置密封圏 25。
在本实施例中， 外套管 3沿其中轴线的剖面呈横放着的 "凸" 字型， "凸，，字型的下半部分位于靠近结晶器铜板 7的一端， 且用 于安装内套管 2以及弹性元件 4。
根据本实施例， 外套管 3与结晶器铜板 7螺接， 螺接本身就 形成了密封， 这是第一重密封。 在弹性元件 4的压迫力下使内套 管 2及内套管 2底部的密封圏 10紧密接触结晶器铜板 7 , 形也第 二重密封。
如果外套管 3与结晶器铜板 7的螺接密封不好， 或是外套管 3 由于结晶器振动或其它原因造成松动或回松， 水会从螺接处渗 入， 但是由于内套管 2在弹性元件 4的压迫力挤压下内套管 2及 内套管 2底部的密封圏 10紧密接触结晶器铜板 7 , 水不会进入感 温组件 1的测温区域， 保证了测温的准确性。
图 12和图 13示出了根据本发明的连铸机结晶器的透视图。 如图所示，构成连铸机结晶器 20的第一侧壁 20A、第二侧壁 20B、 第三侧壁 20C和第四侧壁 20D形成结晶器钢水截面 20E , 各侧壁 分别包括铜板 7和位于铜板外侧的水箱 7，， 各侧壁上分别设有贯 穿水箱 7，和铜板 7的温度检测装置安装孔 21 , 该温度检测装置安 装孔 21可以是现有的连接水箱和铜板的孔，也可以是单独加工的 孔， 供温度检测装置安装于其中。
在连铸机结晶器的各侧壁上设有至少一排温度检测装置安装 孔 21 ,并且水箱 7，的外壁上开设有连接至温度检测装置安装孔 21 的走线槽 22 以及汇集各所述走线槽 21 的汇线槽 23 , 汇线槽 23 的端部连接出线管， 温度检测装置的信号引线通过走线槽、 汇线 槽、 出线管引出至结晶器外。
在图 10和图 11所示的实施例中， 设有两排温度检测装置， 其中汇线槽 23贯穿一排温度检测装置安装孔 21 , 另一排温度检 测装置安装孔 21通过倾斜走向的走线槽 21与汇线槽连通， 以使 温度检测装置的信号布线便于维护。
在本实施例中， 结晶器可以安装很多个温度检测装置， 如果 没有走线槽， 感温组件 1 的电缆将全部棵露在外面， 安装与维护 很不方便。 再者一旦发生溢钢， 钢水流出来很可能会烧坏感温组 件 1的电缆， 造成严重的损失。 而设置走线槽， 感温组件 1的电 缆完全藏在走线槽里面了， 就算是钢水流出来也可以从一定程度 上保护电缆， 从而保护感温组件 1 , 并且安装与维护方便。
本领域技术人员容易想到： 内套管和铜板之间可设置导热垫 片来提高导热性能。 内套管可以由不同导热性能的材料制成， 例 如构成内套管的封闭端的材料的导热性能可大于其它部位的材料 的导热性能。 本发明的温度检测装置也可以应用于未设置走线槽 21 和汇线槽 23 的连铸机结晶器上。 上述各实施例中所记载的区 别技术特征可以相互引用和组合以获得较佳实施例。
通过以上描述可以看出， 根据本发明的温度检测保护装置， 在本发 明的温度检测保护装置中， 设置外套管和内套管， 外套管与结晶器铜板 密封配合， 防止渗水， 内套管的端部形成防水保护部， 对感温组件的感 温部位形成封闭或者密封防水保护。 通过这种设置， 可最大限度地降低 结晶器铜板的渗水的影响。 这样增加了感温组件的使用寿命， 也提高了 温度采集的准确度。
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做的任何修改、 等同替换和改进等， 均应 包含在本发明的保护范围之内。
