摘　　要：本文以武铜炼钢总厂四分厂连铸车间现有设备为基础，介绍了浸入式水口一键快换控制体系、工艺过程等内容，明确了一键快换技术是采用基于结晶器液面自动控制的水口自动快换技术。实际生产中，通过试验不断解决一键快换中遇到的问题，使该厂的一键快换成功率从开始时的76％左右提高到当前99％以上的稳定状态。后工序水口更换过渡坯夹杂改判量较采用一键快换技术之前减少了30％，明显提高了水口坯质量。Based on introducing equipments and technology conditions of continuous casting plant of the 4th sub plant of general steelmaking factory of WISCO, the control system and operating process of SEN quick replacing technology was intro- duced, and the mould level control technology as the base was emphasized at the same time. Through comprehensive industrial scale experiments, several relevant problems were solved in application process, which promoted the rate of one button quick replace of the plant to beyond 99 percent stably from 76 at the beginning, as a consequence, degrading rate of slab for the replacing operation of SEN reduced about 30 percent.
