武钢CSP连铸提高钢包寿命的生产实践

Production practices of increasing service life of ladle in CSP continuous casting of WISCO

针对CSP薄板坯连铸钢包周转过程中出现的包底剥落、包壁侵蚀严重等问题,采取优化包底耐材配置模式、改进熔池砖型、优化包底浇注方法等措施,不断提高钢包使用寿命,由投产初期钢包使用寿命不足90次提高到140次,确保了钢包安全周转。

In light of problem of ladle bottom spalling and the serious ladle wall erosion occurring in the process of the ladle turnover period in the CSP continuous casting a series of counter measures have been implemented such as optimization of the refractory configuration of the ladle bottom, improvement in the bath brick work and optimization of the pouring method of the ladle bottom. As the results the service life of the ladle has been continuously prolonged from the less than 90 heats in the initial stage of commissioning of the ladle to the 140 heats at the present time. The target of reduction of production cost and improvement in the efficiency has been realized and the safeties of ladle turn over ensured as well.
