摘　　要：针对莱钢十机十流小方坯连铸机的高效生产,通过改进中间包稳流器、冲击区永久层、工作层渣线修砌工艺,采用高精度结晶器、高效点状凹槽结晶器铜管及密排喷嘴,优化二次冷却配水模型,实施低过热度浇注浇注、中间包热换,提高了连铸机作业率,实现了高拉速条件下的高质量控制。In response to the efficient production of the ten strand billet continuous casting machine at Laigang,the process of repairing the tundish flow stabilizer,permanent layer in the impact zone,and slag line in the working layer was improved.High precision crystallizers,high-efficiency dot shaped groove crystallizer copper pipes,and densely arranged nozzles were used to optimize the secondary cooling water distribution model.Low superheat pouring and heat exchange in the tundish were implemented to improve the operation rate of the continuous casting machine and achieve high-quality control under high drawing speed conditions.
