Embodiment Construction
[0057] The preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention, and together with the embodiments of the present invention, are used to illustrate the principles of the present invention, but not to limit the scope of the present invention.
[0058] The injection structure of the existing electric arc furnace device requires manual intervention during the whole process. The operator controls the injection structure according to the state of the electric arc furnace. When the electric arc furnace body is tilted or abnormal, the linkage cannot be made in time. The reaction increases the difficulty of operation and is not conducive to improving production efficiency.
[0059] In addition, the injection structure of conventional electric arc furnaces is suitable for general working conditions, but for large-capacity electric arc f...

The invention discloses an electric arc furnace device and a blowing control method thereof, belongs to the field of electric arc furnaces, and solves the problem of whole manual intervention in the movement process of an existing blowing structure. The electric arc furnace device comprises an electric arc furnace, a blowing structure and a control system. The control system comprises a detection unit, a processing unit and a control unit; the detection unit is used for detecting related information of the electric arc furnace and the injection structure and sending the related information of the electric arc furnace and the injection structure to the processing unit; the processing unit is used for receiving and processing related information of the blowing structure and the electric arc furnace from the detection unit and sending corresponding processing result information to the control unit; and the control unit is used for receiving the processing result information from the processing unit, carrying out comprehensive calculation on the processing result information to obtain a movement route of the injection structure, and sending out a control instruction. By the adoption of the electric arc furnace device and the control method thereof, the problem that manual whole-process intervention is needed in the movement process of the injection structure can be effectively solved.
Description
technical field [0001] The invention belongs to the technical field of electric arc furnace steelmaking, and in particular relates to an electric arc furnace device and a blowing control method thereof. Background technique [0002] The oxygen lance in the injection structure of the electric arc furnace door is an important auxiliary device for the electric arc furnace smelting. [0003] At present, the automation level of the traditional electric arc furnace door injection structure is relatively low. When entering the working position, the worker must jog the whole process, so that the oxygen lance can avoid the obstacles in front of the furnace, the furnace door frame, the slag and scrap areas, and spray at the correct position. blow. Due to the inability to sense the position status of the electric arc furnace body and itself in time, the forward, backward, ascending, descending, left swinging, right swinging, upward tilting, and downward tilting actions of the furnace ...
