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.
