Abstract
A method for continuous estimation an instantaneous weight of a graphite electrode being consumed in an electric arc furnace. The method includes the steps of continuously sensing a hydraulic pressure acting on a mast holding the graphite electrode; converting each one of the sensed hydraulic pressures to a corresponding weight of the graphite electrode; and determining from the corresponding weights of the graphite electrode the instantaneous weight of the graphite electrode.

A method for continuous estimation an instantaneous weight of a graphite electrode being consumed in an electric arc furnace, the method comprising the steps of:
- continuously sensing a hydraulic pressure acting on a mast holding the graphite electrode;
- converting each one of the sensed hydraulic pressures to a corresponding weight of the graphite electrode;
- determining from the corresponding weights of the graphite electrode the instantaneous weight of the graphite electrode.
An electric arc furnace(EAF) system comprising:
- an EAF;
- a graphite electrode for each phase of the EAF;
- a mast connected to the graphite electrode, the mast moveable vertically to raise and lower the at least one graphite electrode;
- a hydraulic cylinder including a fluid to raise and lower the mast;
- a pressure transducer sensing a pressure of the fluid;
- a computing device configured to convert the sensed pressure to a weight of the graphite electrode and to determine the instantons weight of the graphite electrode.
