A slag door for a melting furnace for the production of steel is suitable to be associated with an aperture provided in a lateral wall of the melting furnace and to cooperate with a slag channel provided inside the melting furnace itself.

Slag door for a melting furnace

The method for adjusting the impedance of one or more phases of a secondary circuit of an electric furnace, in order to limit the unbalance between the phases themselves comprises the transformer (), a variable impedance secondary circuit for one or more phases (FFF), the rigid and fixed interconnection () for each phase (FFF) connected to the transformer, the flexible cables () connected by means of the proximal end to the fixed interconnection (), the electrode holding arms () connected to the distal end of the flexible cables (), the conductive electrodes () fixed to the respective electrode holding arms (). The rigid and fixed interconnection () of a phase (FFF) comprises at least one turn (), wherein the impedance is either continuously or discreetly variable in order to obtain the desired impedance value.

Electric circuit for electric arc furnace

A control method for melting a metal charge in a furnace comprising at least a hearth containing the metal charge and a roof. The method provides that the hearth is weighed by means of a plurality of weighing elements distributed along the perimeter of the base of the hearth, and that the values detected by the plurality of weighing elements are sent to a control unit in order to obtain information relating to the distribution of the metal charge inside the hearth.
