请参考图1和图2，本公开提供了一种结晶器铜板100，其为长方体板状结构，其包括相对的固定面101和模具面102、相对的顶面103和底面104以及两个相对的侧面105。
其中，固定面101被配置为与固定水箱或转接背板连接并实现背面冷却，而模具面102被配置为对金属进行连铸。
固定面101设置有多列配置为连接外部固定水箱或转接背板的固定螺孔111及形成螺孔周围的台面112，其中，固定螺孔111和台面112与固定面101位于同一水平面。换而言之，本公开中的固定螺孔111为沉孔，更具体地，本公开中的固定螺孔111为设置有螺纹的沉孔(即螺孔)，沉孔的设置能够保证固定面101与固定水箱或转接背板的连接更加紧密。同时，当需要取下或更换结晶器铜板100时，经由设置有螺纹的沉孔能够将固定面101与固定水箱或转接背板容易地分离，从而便于对结晶器铜板100进行维护或维修。
可选地，每列的多个固定螺孔111之间连接有加强筋113。具体地，每列的多个固定螺孔111中任意相邻的两个固定螺孔111之间连接有加强筋113，并且加强筋113与两个固定螺孔111的连接方式包括，但不限于，固定连接，诸如焊接或粘接，或可拆卸链接。本实施例中，加强筋113的宽度为5-8mm。加强筋113的设置一方面增强了台面112之间的强度，使固定面101与固定水箱或转接背板的连接更加牢固；同时还能增加热交换的能力，其同样起到将固定面101的水道变窄，从而提高流速的作用，冷却效果更佳。具体地，当 冷却介质在冷却通道内流动时，由于加强筋113的设置，水流通道变窄，水流的流速更高，同时热交换面积增加，冷却能力更强。
任意相邻两列固定螺孔111之间均设置有冷却通道120，本公开中的冷却通道120凹陷于固定面101，具体而言，冷却通道120的底部低于固定面101约5-15mm。冷却通道120用于供冷却介质流动，在具体的实例中，在结晶器铜板100的接近于顶面103或底面104且与固定水箱或转接背板进水口对应的位置设置有开口，并且在结晶器铜板100的接近于底面104或顶面103且与固定水箱或转接背板出水口对应的位置设置有开口，因此，可以在结晶器铜板100的接近于顶面103或底面104且与固定水箱或转接背板进水口对应的开口进水，相应的，在接近于底面104或顶面103且与固定水箱或转接背板出水口对应的开口出水，以形成循环水冷却。
冷却通道120内具有弯月面区域121，通常来说，结晶器铜板100从顶面103向底面104的方向的第二排固定螺孔111以及台面112所在的区域称之为弯月面区域121。弯月面区域121的钢水初期凝固是决定铸坯的表面质量与内部质量的关键因素，因此，需要对弯月面区域121进行充分且均匀的冷却。
具体到本公开中，弯月面区域121设置有一段分流冷却筋122，分流冷却筋122的顶端和底端中的至少一端为用于改变冷却介质运动方向的锥角123。
分流冷却筋122为直条形结构，该直条形结构能够使得冷却介质(诸如，水)在锥角123处进行转向后，在后续的运动中不再受到分流冷却筋122的影响，此外，本公开中，分流冷却筋122的宽度为6-10mm，并且加强筋113的宽度小于分流冷却筋122的宽度，这样的设置能够在固定面101的大小保持不变的情况下，尽可能扩大冷却通道120的水道区域，从而增加水流冷却面积，使得水流在冷却通道120内的其他区域(即除了弯月面区域121的其他区域)时水流速度较小，而在弯月面区域121时水流速度较大。本公开中，通过仅在弯月面区域121设置分流冷却筋122，而未在冷却通道120内的其他区域(即除了弯月面区域121的其他区域)设置分流冷却筋122，能够将弯月面区域121的水道变窄，从而使水流的流速更高，热交换面积增加，冷却能力更强。有助于降低弯月面区域121铜板的温度，有助于弯月面区域121冷却更均匀化，且有助于减轻弯月面区域121铜板的热疲劳裂纹的生成。本公开中，将分流冷却筋122的顶端和底端中的至少一端设计为锥角123，当水流撞击在锥角123时，可使水流改变方向，进而形成无序的、水流相互混掺的紊流，从而提高了冷却的效果。
具体地，在弯月面区域121中设置分流冷却筋122，能够使弯月面区域121的水道变窄，从而当冷却介质(诸如，水)流经弯月面区域121时，冷却介质的流速变高，使得冷却能力更强、冷却效果更好；同时，分流冷却筋122的设置能够有效增大热交换面积，使得冷却能力得到进一步加强，并且冷却更加均匀化。冷却的快速化和均匀化均有助于减轻弯月面区域121铜板的热疲劳裂纹的生成。
进一步地，分流冷却筋122的顶端和底端中的至少一端设计为锥角123，即分流冷却筋122靠近顶面103的一端被配置为锥角123，或者分流冷却筋122靠近底面104的一端被配置为锥角123，或者分流冷却筋122的两端均被配置为锥角123。当冷却介质(诸如，水)流经弯月面区域121时，冷却介质撞击锥角123后，其流动速度增加且流动方向从有序变为无序，从而能在弯月面区域121处形成紊流(即湍流)，以进一步提高冷却速度，改善冷却效果。
可选地，本公开中，将任意一列从上至下的第二个固定螺孔111限定为区域孔114，区域孔114的圆心与锥角123的顶角124的连线部分地位于锥角123的锥形面125上(如图2中虚线部分所示)。具体地，本公开中的锥角123的角度为60-90°。该角度可以使得水流能够沿着锥角123的锥形面125流动，进而冲击至区域孔114对应的台面112上，通过对区域孔114与锥角123的形状的限制，能够保证在水流冲击锥角123时，水流流向改变并冲击至区域孔114的台面112上，并在此处产生紊流，进而有效提高区域孔114对应的台面112的冷却能力，从而使得弯月面区域121冷却更为均匀，冷却效果更好。结晶器铜板100在弯月面区域121的热面温度降低，从而减轻或消除弯月面区域121铜板的热疲劳裂纹，延长结晶器铜板100的使用寿命，同时可以承受更高的连铸拉速。
此外，本公开还提供了一种连铸结晶器，其包括上述结晶器铜板100。其能够实现更均匀的冷却，有利于减少结晶器铜板100的热疲劳裂纹，延长结晶器铜板100的使用寿命。
根据本公开提供的一种结晶器铜板100，该结晶器铜板100的工作原理如下：利用固定面101上的固定螺孔111以及形成螺孔周围的台面112与外部的固定水箱或转接背板连接，实现结晶器铜板100的固定，随后利用密封圈对固定面101的外周进行密封，有效避免冷却介质流出。本公开中加强筋113的设置不仅仅能够加强台面112之间的强度，同时也能够增加热交换的能力，起到更佳的冷却效果。接着向冷却通道120内通入冷却介质，冷却介质在冷却通道120内流动，当运动到弯月面区域121时，由于分流冷却筋122的设置，水流通道变窄，水流的流速更高，热交换面积增加，冷却能力更强。因此，分流冷却筋122的设置有助于降低弯月面区域121铜板的温度，有助于弯月面区域121冷却更均匀 化，有助于减轻弯月面区域121铜板的热疲劳裂纹。而本公开中分流冷却筋122的顶端和底端中的至少一端设计为锥角123，当水流撞击在锥角123时，可使水流改变方向，进而使水流冲向从上到下第二个固定螺孔111及形成螺孔周围的台面112，并在此形成紊流，从而提高了此处的冷却效果。对结晶器铜板100的冷却能力更强，且能够实现相对均匀的冷却，同时铸坯冷却不仅能力强，而且冷却均匀，坯壳应力小，连铸拉速可相应提高。
以下结合具体的实施例进行说明。请参考图1，本实施例提供了一种结晶器铜板100，其为长方体板状结构，其包括相对的固定面101和模具面102、相对的顶面103和底面104以及两个相对的侧面105。
其中，固定面101设置有多列固定螺孔111及形成螺孔周围的台面112，固定螺孔111和台面112与固定面101位于同一水平面。每列的多个固定螺孔111之间连接有加强筋113。本实施例中，加强筋113的宽度为5mm。
任意相邻两列固定螺孔111之间均设置有凹陷于固定面101的冷却通道120，冷却通道120的底部低于固定面101约8mm。冷却介质从结晶器铜板100的接近于底面104且与固定水箱或转接背板进水口对应的开口进入，流经冷却通道120后，从接近于顶面103且与固定水箱或转接背板出水口对应的开口排出。冷却通道120内具有弯月面区域121，且在冷却通道120对应于弯月面区域121的部分设置有直条形的宽度为7mm的分流冷却筋122，分流冷却筋122的底端设置有沿着分流冷却筋122的轴心线方向突出的角度为60°的锥角123，本实施例中，将任意一列从上至下的第二个固定螺孔111限定为区域孔114，区域孔114的圆心与锥角123的顶角124的连线部分地位于锥角123的锥形面125上。
冷却介质在冷却通道120内流动时，锥角123使得水流流向改变，并冲击至区域孔114的台面112上，并在此处产生紊流，进而有效提高区域孔114对应的台面112的冷却能力，从而使得弯月面区域121冷却更为均匀。结晶器铜板100在弯月面区域121的热面温度降低，从而减轻或消除弯月面区域121铜板的热疲劳裂纹，延长结晶器铜板100的使用寿命，同时可以承受更高的连铸拉速。请继续参考图3，本实施例提供了一种结晶器铜板100，其为长方体板状结构，其包括相对的固定面101和模具面102、相对的顶面103和底面104以及两个相对的侧面105。
其中，固定面101设置有多列固定螺孔111及形成螺孔周围的台面112，固定螺孔111和台面112与固定面101位于同一水平面。每列的多个固定螺孔111之间连接有加强筋113。本实施例中，加强筋113的宽度为8mm。
任意相邻两列固定螺孔111之间均设置有凹陷于固定面101的冷却通道120，冷却通道120的底部低于固定面101约15mm。冷却介质从结晶器铜板100的接近于顶面103且与固定水箱或转接背板进水口对应的开口进入，流经冷却通道120后，从接近于底面104且与固定水箱或转接背板出水口对应的开口排出。冷却通道120内具有弯月面区域121，且在冷却通道120对应于弯月面区域121的部分设置有直条形的宽度为10mm的分流冷却筋122，分流冷却筋122的顶端设置有沿着分流冷却筋122的轴心线方向突出的角度为90°的锥角123，本实施例中，将任意一列从上至下的第二个固定螺孔111限定为区域孔114，区域孔114的圆心与锥角123的顶角124的连线部分地位于锥角123的锥形面125上。
冷却介质在冷却通道120内流动时，锥角123使得水流流向改变，并冲击至区域孔114的台面112上，并在此处产生紊流，进而有效提高区域孔114对应的台面112的冷却能力，从而使得弯月面区域121冷却更为均匀。结晶器铜板100在弯月面区域121的热面温度降低，从而减轻或消除弯月面区域121铜板的热疲劳裂纹，延长结晶器铜板100的使用寿命，同时可以承受更高的连铸拉速。请参考图4，本实施例提供了一种结晶器铜板100，其为长方体板状结构，其包括相对的固定面101和模具面102、相对的顶面103和底面104以及两个相对的侧面105。
其中，固定面101设置有多列固定螺孔111及形成螺孔周围的台面112，固定螺孔111和台面112与固定面101位于同一水平面。每列的多个固定螺孔111之间连接有加强筋113。本实施例中，加强筋113的宽度为6mm。
任意相邻两列固定螺孔111之间均设置有凹陷于固定面101的冷却通道120，冷却通道120的底部低于固定面101约12mm。冷却介质从结晶器铜板100的接近于底面104且与固定水箱或转接背板进水口对应的开口进入，流经冷却通道120后，从接近于顶面103且与固定水箱或转接背板出水口对应的开口排出。冷却通道120内具有弯月面区域121，且在冷却通道120对应于弯月面区域121的部分设置有直条形的宽度为8mm的分流冷却筋122，分流冷却筋122的底端和顶端均设置有沿着分流冷却筋122的轴心线方向突出的角度为80°的锥角123，本实施例中，将任意一列从上至下的第二个固定螺孔111限定为区域孔114，区域孔114的圆心与锥角123的顶角124的连线部分地位于锥角123的锥形面125上。
冷却介质在冷却通道120内流动时，锥角123使得水流流向改变，并冲击至区域孔114的台面112上，并在此处产生紊流，进而有效提高区域孔114对应的台面112的冷却能力，从而使得弯月面区域121冷却更为均匀。结晶器铜板100在弯月面区域121的热面温度降低，从而减轻或消除弯月面区域121铜板的热疲劳裂纹，延长结晶器铜板100的使用寿命， 同时可以承受更高的连铸拉速。
综上所述，本公开利用固定面101上的固定螺孔111及形成螺孔周围的台面112与外部的固定水箱或转接背板连接，实现结晶器铜板100的固定，随后利用密封圈对固定面101的外周进行密封，从而有效避免冷却介质流出。本公开中加强筋113的设置不仅仅能够加强台面112之间的强度，同时也能够增加热交换的能力，起到更佳的冷却效果。接着向冷却通道120内通入冷却介质，冷却介质在冷却通道120内流动，当运动到弯月面区域121时，由于分流冷却筋122的设置，使水流通道变窄，水流的流速更高，热交换面积增加，冷却能力更强。有助于弯月面区域121冷却面的扩大，减小冷却通道120的截面面积，增大冷却水流的速度，强化冷却能力。因此，分流冷却筋122的设置有助于降低弯月面区域121铜板的温度，有助于弯月面区域121冷却更均匀化，有助于减轻弯月面区域121铜板的热疲劳裂纹，延长结晶器铜板100使用寿命。而本公开中在分流冷却筋122的顶端和底端中的至少一端上设置的锥角123，当水流撞击在锥角123时，可使水流改变方向，进而使水流冲向从上到下第二个固定螺孔111及形成螺孔周围的台面112，并在此形成紊流，从而提高了冷却的效果。对结晶器铜板100的冷却能力更强，且能够实现相对均匀的冷却，同时铸坯冷却不仅能力强，而且冷却均匀，坯壳应力小，连铸拉速可相应提高。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本公开的保护范围之内。
