Composite slab continuous casting tundish turbulence controller
The invention relates to the technical field of continuous casting refractory material processes, in particular to a composite slab continuous casting tundish turbulence controller and a preparation method thereof. The tundish turbulence controller comprises a shell, a sleeve core and a bottom plate, the bottom plate is arranged on the bottom surface of an inner cavity of the shell, and the sleevecore is arranged in the inner cavity of the shell, the longitudinal center line of the sleeve core coincides with the longitudinal center line of an inner cavity of the shell, a combining seam is formed between the shell and the sleeve core, a circular-truncated-cone-shaped magnesium prefabricated part is arranged outside the sleeve core, a paraboloid-shaped inner cavity is formed inside the sleeve core, the bottom plate is a whole magnesia carbon brick, the sleeve core is arranged in the shell of the turbulence controller in a sleeved mode, a joint seam between the shell and the sleeve coreis filled with sintered magnesia, so that the response time and the average retention time of molten steel can be prolonged, the volume of piston flow is increased, the volume of a dead zone is reduced, turbulent energy of steel ladle injection flow can be effectively reduced, a molten steel flow field in a tundish is well improved, and the problem of slag entrapment caused by injection flow in animpact zone is effectively solved.
本发明涉及连铸耐火材料工艺技术领域，具体为一种复合式板坯连铸中间包湍流控制器及其制备方法，中间包湍流控制器包括外壳、套芯和底板，底板设置在外壳内腔的底部表面，套芯设置在外壳的内腔内，且套芯的纵向中心线与外壳内腔的纵向中心线重合，外壳和套芯之间设有结合缝，套芯外部为圆台形镁质预制件，套芯内部为抛物面形的内腔，底板为一整块镁碳砖，将套芯套装于湍流控制器的外壳内，外壳和套芯之间的结合缝采用烧结镁砂填实，可以延长钢液的响应时间和平均停留时间，增加活塞流体积，减小死区体积，能有效降低钢包注流的紊动能并较好地改善中间包内钢液流场，且有效解决了冲击区内注流卷渣问题。
