连铸扇形段非通轴的三分节辊的辊与辊之间漏水,严重地影响板坯的表面质量及扇形段的维护成本。对分节辊的特点及对漏水原因进行了深入的分析研究,得出问题的关键是如何保证三分节辊同步并且分节辊之间为非刚性连接,从而确定了辊与辊之间用十字滑块联轴器连接的方案,实践证明该方案能完满地解决三分节辊漏水问题,并极大提高辊子寿命,改善铸坯表面质量。
Leakage of water between the roller and the roller of the non-through-shaft three-section roller of continuous casting fan segment seriously influences the surface quality of the slab and the maintenance cost of the fan segment. The characteristics of the section roller and the cause of water leakage were analyzed in depth. The key problem was how to ensure that the three-section roller synchronously and the non-rigid connection between the section rollers, thus confirming the relationship between roller and roller Cross slider coupling scheme, the practice proved that the program can solve the problem of three-section roller leakage, and greatly improve the life of the roller and improve the slab surface quality.
