首秦连铸机分节辊冷却水密封技术研究及应用

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。

Technical Study and Application of Split Roller Cooling Water Sealing of Caster in Shouqin

Leaking between the three split rollers of caster segment for the non-entire shaft roller has a serious influence on the surface quality of the slab and the costs of segment maintenance. In this study, the characteristics and reasons of leakage points section of the roller were analyzed, and the key point was obtained which is that how to ensure the synchronization of three split rollers and nonrigid connection between rollers. According to the analysis, the slider with a cross shaft coupling was confirmed. Practice proved that the scheme can perfect the solution of the three split rollers leaking problem, and greatly prolong the roller life, and improve the surface quality of slab.
