Through researching the traditional production process and feeding mode of ferroalloy electric furnace,to solve the problems of safety hidden danger,high labor intensity,low production efficiency,flue gas and dust overflow and serious environmental pollution in the traditional feeding process,SolidWorks 3D software was used to design a hydraulically driven automatic feeding device controlled by a programmable controller.The device is remotely operated and occupational health hazards and potential safety hazards caused by manual cloth intervention can be solved.The method of constant rotation angle,variable inclination angle and angular velocity was adopted for distribution.The distribution scope can basically cover the smelting area around the electrode,and the distribution between the two electrodes has better effect.The hydraulic cylinder,connecting rod and slewing support are used to realize the slewing and pitching of the feeding chute,which makes the feeding more efficient and uniform,and the feeding automation level is greatly improved.
