Discussion and Analysis on Measurement Methods for Mould Friction During High Efficiency Continuous Casting

The friction between the mould and slab has important influences on the process of continuous casting and the slab quality. In this paper, based on the continuous slab caster under hydraulic oscillation, the measurement methods of mould friction are studied. The extraction and realization of friction work method and pressure method are discussed, and the relationship of measured parameters of two methods is deduced in theory. On the basis of the measured data in continuous slab casting, the friction measured parameters are calculated by the two measurement methods in different conditions, and the comparative analyses on the advantages and applicability of the two measuring methods are performed. The research provides theoretical and experimental bases for the reasonable selection and application of friction measurement method.
