本发明属于冶金铸造技术领域，涉及一种水 平连铸结晶器，该水平连铸结晶器包括：内套、外 壳和冷却结构；所述外壳包覆在所述石墨内套的 外侧，所述冷却结构设置在所述外壳和石墨内套 之间，所述冷却结构具有2个独立的上冷却腔和 下冷却腔，所述冷却结构具有2个独立的上冷却 腔和下冷却腔，且每个冷却腔的两端均设有对称 设置2组进水口和出水口。本发明提供的结晶器 设置独立的冷却腔，且在冷却腔的冷却板设有平 行分布的圆弧凹槽，凹槽的方向与水流方向垂 直，一方面大大增加了冷却水与冷却铜板之间的 换热面积，另一方面增加了结晶器内部冷却水的 紊乱度，强化了结晶器中不同部位冷却水层的对 流换热，提高了换热时热传导为主的换热效率。 

The present invention belongs to the field of metallurgical casting technology and relates to a horizontal continuous casting crystallizer, the horizontal continuous casting crystallizer comprising: an inner sleeve, a shell and a cooling structure; The shell is wrapped on the outside of the graphite inner sleeve, the cooling structure is disposed between the shell and the graphite inner sleeve, the cooling structure has 2 independent upper cooling chambers and lower cooling chambers, the cooling structure has 2 independent upper cooling chambers and lower cooling chambers, and both ends of each cooling cavity are provided with symmetrically provided with 2 groups of water inlets and outlets. The crystallizer provided by the present invention is provided with an independent cooling cavity, and the cooling plate of the cooling chamber is provided with parallel distributed arc grooves, and the direction of the groove is perpendicular to the direction of the water flow. On the one hand, it greatly increases the heat exchange area between the cooling water and the cooling copper plate, on the other hand, it increases the disorder of the cooling water inside the crystallizer, strengthens the convective heat transfer of the cooling water layer in different parts of the crystallizer, and improves the heat exchange efficiency dominated by heat conduction during heat exchange.
