Abstract (en)
[origin: WO9422618A1] The invention relates to a method for regulating the level of the meniscus (13) of molten metal in a mould (5) of a continuous casting machine, wherein the electric signals provided by at least one pair of sensors (17, 18) placed above said meniscus are collected, said signals being a function of the respective distances (h1, h2) between said sensors and said meniscus, said two signals being then combined so as to obtain a unique signal representative of a ficticious level of said meniscus, said signal being then sent to control means (15, 24) of a regulation device (14) which regulates the flow rate of metal entering the mould, so that said control means actuate said device in order to bring said ficticious level of the meniscus to a predetermined set value (h), caracterised in that each signal from the sensors is conditioned by eliminating the oscillations having both a frequency higher than a threshold value (F) and an amplitude smaller than a threshold value (D). The invention relates also to a combination mode of said signals, and to a device for implementing such method.
