METHOD OF ADJUSTMENT FOR CONTINUOUS CASTING MOULD MELT HEEL Russian patent published in 2014 - IPC B22D11/16 B22D11/18 

FIELD: process engineering.

SUBSTANCE: liquid metal feed to continuous casting mould is stopped by interlock. Partially hardened formed article is released from continuous casting mould with the help of unloading device. Measured actual casting level magnitude (hG) is fed to casting level controller. The latter uses said actual magnitude (hG) and appropriate preset magnitude (hG*) to define the interlock preset position (p*). Measured actual magnitude (hG) and appropriate preset position (p) are fed to disturbance compensator. Said compensator defines the expected magnitude (hE) for casting level to subtract it from said actual magnitude (hG). Difference (e) in said compensator is fed to differential regulator for it to define the regulator output signal (e'). Said regulator output signal (e') is multiplied by ON factor (k). Said regulator output signal (e') is multiplied by ON factor (k) as the disturbance compensation magnitude (z) is included in preset position (p*). Besides, regulator output signal (e') includes feed signal (Z) derived from actual position (p). Result of initiation of disturbance inside compensator (20) is fed to integrator, its output signal (hE) corresponding to expected magnitude (hE) for melt heel.

EFFECT: more accurate adjustment of melt heel.
