Experimental Simulation of N--EMBr on Strip Casting with Twin Roll
|
Abstract:
A model for simulating suppression of level fluctuation in mold of twin-roll strip caster with nozzle electromagnetic brake (N-EMBr), i.e., imposed a stationary magnetic field and direct current in nozzle, was established. The momentum of metal liquid in nozzle and level fluctuation in twin-roll pool were measured under different conditions, including the immerging depth of nozzle, current and magnetic field. The experiment results showed that the momentum of liquid metal, amplitude and frequency of fluctuation all were decreased with current increasing. It was found that the N-EMBr technique for fluctuation suppression is effective to twin-roll strip casting mold.
