| 对液压振动下的板坯连铸结晶器摩擦力检测方法——摩擦功法进行了研究，阐述了摩擦功法的检测原理和实现方法，并通过现场试验对检测方法误差进行了分析和验证．基于板坯连铸结晶器摩擦力的现场实测数据，讨论了拉速变化对摩擦力影响，并对正弦和非正弦振动方式下的摩擦力检测结果进行了分析．结果表明，运用摩擦功法进行摩擦力检测，能够很好地反映铸坯与结晶器之间的摩擦和润滑状况，为摩擦功法用于液压振动下铸坯与结晶器之间摩擦力的在线检测提供了理论参考和实验依据． |
| 英文摘要: |
| Based on the slab continuous casting under hydraulic oscillation, the measurement method of mould friction — friction work measurement method is studied. The extraction and the realization of friction work measurement method are discussed and the error of friction is also analyzed and verified through the casting tests. Finally, according to the monitored data in slab continuous casting, the effects of casting speed on friction are discussed, and the comparative analysis is carried out to the friction results under the sinusoidal mode and the non-sinusoidal mode. The results show that the friction monitored by the friction work method can well reflect the lubrication situation between the mould and slab. This research provides the theoretical and experimental bases for the mould friction monitored online with the friction work method under the hydraulic oscillation. |
