A load signal representing the load between a mold and an oscillating mechanism is separated into its static offset and dynamic components. The static offset signal is compared with a free-running static offset to obtain a substantially DC signal representing the DC component of mold friction. A DC voltage is generated corresponding to the RMS value of the dynamic load signal component, and a reference voltage corresponding to the RMS value of the dynamic signal component of a free-running load signal is subtracted in order to obtain a substantially DC signal representing the dynamic component of mold friction.

Continuous casting mold friction monitor

A mold for continuously casting molten metal, which mold has a friction-reducing material disposed so that the surfaces of the copper liner and the steel backing plate of the mold bear against this material instead of directly against each other. Specifically, the friction-reducing material must possess a coefficient of friction significantly less than the coefficient of friction which results when copper bears against steel. Consequently, the restraint against thermal expansion is minimized, resulting in less distortion of the liner.
