    摘要： The present invention refers to a method and to a control and tracking system of the charge of material transported by a continuous supply conveyor (2) of a metallurgical furnace (3), in particular an electric furnace for the production of steel, wherein said continuous conveyor (2) comprises, in sequence starting from its inlet end towards its outlet end, a loading section (2A) of the charge of material to be supplied to said furnace (3), a preheating section (2B) of the charge of material loaded and an introduction section (2C) into said furnace (3) of the preheated charge of material, and wherein along said loading section (2A) at least a first loading station (200) of material is present, wherein the method comprises the steps consisting in determining (101) the type and the weight of the material of a first charge fraction to be loaded into the first loading station (200) in function of a predetermined charge recipe (100), supplying (102) the first loading station (200) with the first charge fraction, detecting (103) the weight of the first charge fraction, discharging (104) the first charge fraction (C1) onto the continuous conveyor (2), marking (105) the first charge fraction (C1) through identification means (M1, M1', M1''), detecting (106) the overall dimensions of the first charge fraction (C1) discharged onto the continuous conveyor (2), estimating (107, 108) the advancing speed of the first charge fraction (C1) along the loading section (2A) of the continuous conveyor (2) and the arrival time of the first charge fraction (C1) entering a possibly subsequent loading station (200n) of a further charge fraction or the preheating section (2B), and, in proximity to the inlet of the preheating section (2B), recognising (115) in the charge of material discharged onto the continuous conveyor (2) the first charge fraction (C1) and possible further charge fractions (Cn) subsequently discharged onto the continuous conveyor (2) by means of the respective identifying means (Ml, Mn), estimating (117, 118) the advancing speed of the first charge fraction (C1) and of possible further charge fractions (Cn) subsequently discharged onto the continuous conveyor (2) along the preheating section (2B) and the respective arrival time to the introduction section (2C) into the furnace (3).

    摘要： A movable device for injecting oxygen and other technical materials into an electric arc furnace comprising a housing (16) situated above a portion of a step (13) of a crucible (11) and equipped with a cooling coil (15), an injection lance (20) of oxygen and other technical materials, supporting (23, 26) and moving means (21, 22, 24) of the lance between minimum and maximum range points of the liquid bath level contained therein, positioned in the housing (16), an opening (27) situated in the housing and facing the inside of the crucible in which the lance is transferably guided, scraping means (28) being envisaged between the opening (27) and the lance (20).
