Carbon-free steel ladle wall painting process

The invention puts forward a carbon-free steel ladle wall painting process and solves the problems of poor bonding effect and early falling of a steel ladle wall repair material. The carbon-free steelladle wall painting process is characterized in that painting process operation steps sequentially comprise cooling, clearing, material mixing, painting, maintenance and baking during steel ladle cold repair. In the steel ladle wall painting repair and maintenance process, overall ladle wall painting is adopted, when a steel ladle is used, painting layers form a whole and are sintered together with the ladle wall, the binding force is greatly enhanced, and the erosion speed of an original ladle wall is greatly delayed by implementing constant protection and maintenance of the ladle wall. 本发明提出了种无碳钢包包壁涂抹工艺，解决了钢包包壁修补料粘结效果差和早期掉落的问题，种无碳钢包包壁涂抹工艺，其特征在于，钢包冷修时涂抹工艺操作步骤依次为冷却、清理、混料、涂抹、养护、烘烤，本发明提供的钢包包壁涂抹修补维护工艺，采用包壁整体涂抹，钢包使用时，涂抹层形成个整体并与包壁烧结在起，结合力大大增强，通过对包壁实施不断的保护与维护，极大的延缓了原包壁的侵蚀速度。
