    摘要： 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 (31), a variable impedance secondary circuit for one or more phases (F1, F2, F3), the rigid and fixed interconnection (32) for each phase (F1, F2, F3) connected to the transformer, the flexible cables (33) connected by means of the proximal end to the fixed interconnection (32), the electrode holding arms (34) connected to the distal end of the flexible cables (33), the conductive electrodes (35) fixed to the respective electrode holding arms (34). The rigid and fixed interconnection (32) of a phase (F1, F2, F3) comprises at least one turn (11), wherein the impedance is either continuously or discreetly variable in order to obtain the desired impedance value.

    摘要： Method to create three-dimensional bodies (30), for example models, formers, finished products, semi-finished products, among others, from a medium (12) consisting of particles, by producing a number of cross-sectional layers (25), each and every one representing a cross section of an object that has to be manufactured, whereby by means of an energy producing device (22a), which moves over the medium, the particles, in the just then topmost layer, in chosen areas, are connected at least with each other or with each other and with a preceding layer, in accordance with signals from a control unit (20). Particles that are not connected in respective layers are removed. The energy producing device (22a), which comprises at least one electrode (22b), forms one of the poles in a circuit, where the other pole is constituted of said medium (12), which is electrically conducting or semiconducting when these poles are connected to at least a voltage source (40), whereby energy waves are formed between said electrode and said medium (12), for example in form of at least an electric arc or heat, that connect the material particles of said medium by changing the physical characteristics of said particles in said chosen area (25).

    摘要： An electric power apparatus for an electric arc furnace (60) comprises at least one electrode (62) and is connectable to a power network (50) to supply to the electrode (62) the electric energy to generate an electric arc to melt a metal mass. The apparatus comprises an electric regulation unit (12) interposed and connected to the power network (50) and to the electrode (62) and configured to regulate at least one electric quantity for powering the electrode (62). The apparatus comprises at least one detection device (20, 22) to detect the electric quantity, interposed between the electrode (62) and the electric regulation unit (12), a positioning device (46) to move the at least one electrode (62) nearer to/away from the metal mass to be melted and a control and command unit (16).
