Description
Technical field
The utility model relates to a kind of high melt reduction three-phawse arc furnace.
Background technology
Three-phawse arc furnace commonly used is made up of body of heater, turndown device, bell lifting and rotating mechanism, electrode lifting device, hydraulic control department; Body of heater is made up of bell, fire door, lander and shaft; Build by laying bricks or stones with basic refractory or acid refractory furnace bottom and furnace wall, and the ratio of furnace depth and furnace diameter D is less than 1.During turndown, electrode lifting device, bell, body of heater together fascinate, and turning angle is less than 50 degree.Wide, big because of burner hearth, be difficult for insulation, turning angle is little, and the material that is difficult for fettling and fusing is difficult to all pour out.
Summary of the invention
The purpose of the utility model just provides a kind of simple in structure, easy to use, and body of heater can be made the high melt reduction three-phawse arc furnace of 360 degree angles rotation.
The high melt reduction three-phawse arc furnace of the utility model; Comprise the hositing mechanism of furnace roof, electrode, bell, burner hearth, body of heater, body of heater rotational delay machine, body of heater rotating shaft holder, the hositing mechanism of furnace roof promotes hydraulic cylinder, cylindrical column, frequency conversion type reducing gear, conductive cross arm, counterweight, rise fall of electrodes tooth bar, bell rotating shaft, bell reel cage platform, rise fall of electrodes column by bell to be formed, and cylindrical column is fixed on the ground; Bell promotes hydraulic cylinder and is installed in the cylindrical column; The top that the bell rotating shaft is located in the cylindrical column, bell promotes hydraulic cylinder, bell reel cage platform and bell rotating shaft are affixed, and three cover rise fall of electrodes columns are welded on the bell reel cage platform; Three cover frequency conversion type reducing gears are installed on the bell reel cage platform; Three cover conductive cross arms are installed on respectively on the three cover rise fall of electrodes columns, and counterweight is placed in the rise fall of electrodes column, is connected the conductive cross arm front end through steel wire rope; Electrode holder is held in the conductive cross arm electrode clamping hole; Bell is installed on the bell reel cage platform of body of heater top, and the body of heater rotating shaft holder is installed on the ground, and body of heater is installed on the body of heater rotating shaft holder; Body of heater rotational delay machine is installed on the ground and with body of heater and is connected, and the furnace depth of body of heater and the ratio of diameter are 1.2-5.0.
The high melt reduction three-phawse arc furnace of the utility model is threaded to the body of heater top with bell during work, and pine is pressed; Lean on bell reel cage platform deadweight compression furnace cover lifting hydraulic cylinder, bell and body of heater close, and drive tooth bar through the frequency conversion type reducing gear and descend; Thereby make electrode drop to burner hearth bottom, the charging aperture adding material through bell send electric starting the arc melting material; About frequency conversion type reducing gear control electrode, thereby the size of control electric current realizes fusion process.After reaching technological requirement, the power supply of closed electrode promotes electrode, starts the furnace cover lifting hydraulic cylinder; With bell reel cage platform jack-up, rotate bell reel cage platform then, make electrode and bell leave body of heater; Start body of heater rotational delay machine, drive the body of heater rotation, melted material is poured out.After material is poured out in the stove, body of heater is rotated to duty, with bell reel cage distal ends to body of heater top, get into next melting program again.
The high melt reduction three-phawse arc furnace of the utility model is simple in structure, easy to use; The ratio of furnace depth and furnace diameter is 1.2-5.0, and promptly furnace diameter is little and dark, can the more loose material of disposable adding; The heat radiation scope that electric arc produces is little, so temperature is high in the stove.During the body of heater rotation, body of heater separates with electrode and bell, can do the rotation of 360 degree angles, and the anglec of rotation is big, can whole materials in the stove be poured out.
