FIELD: metallurgy.
SUBSTANCE: proposed method comprises using probes imbedded in mould copper plate to metal film height level. Said probes house measuring fibers made up of waveguides. Laser beam is directed into said waveguides to use estimation device foe determination of metal film height in mould proceeding from obtained temperature distribution. Estimation is performed using method exploiting Bragg fiber lattice.
EFFECT: simple, high-accuracy temperature control.
