To meet the need for regulating the oxygen injection of the electrofusion brick solution on the inner side of the electric arc furnace, to enhance the effect of oxygen injection, to increase the purity of the electrofusion brick, and to improve the quality of the electrofusion brick.
1 Oxygen gun device consists of oxygen gun, transmission device (lifting, rotating) and bracket.
Oxygen gun body on one side of the sliding frame, located in the middle of the sliding frame sliding set up a regulating mechanism; regulating mechanism includes a mounting frame, located in the upper end of the mounting frame is set up with a drive motor, and the drive motor drives the gear block meshed gear shaft rotation, is located in the gear shaft through the mounting frame side of the set up of the mobile gear rotation, the mobile gear and the sliding frame set up in the rack meshing, and regulating the set up of the side of the oxygen gun body along the rack Reciprocating motion, the utility model, located in the said tooth shaft through the mounting frame set on one side of the mobile gear rotation, easy to the oxygen gun body along the sliding frame reciprocating motion, easy to the oxygen gun body can be used through the adjusting mechanism to achieve the oxygen gun body for expansion and contraction adjustments
2 The main equipments of the valve station are configured according to the requirements of Party A: such as pressure transmitter, flow meter, differential pressure transmitter and supporting multi-valve group, pneumatic regulating valve, pneumatic switching valve, RTD and so on.
3 electrical system performance is comprehensive, fast running speed, strong and reliable, strong communication ability, easy maintenance, etc., through the cooling water detection signal and oxygen, oxygen detection signal is delivered to the PLC control system, PLC adopts advanced German Siemens SIMATICS7-1200PLC, put into the whole process of automatic control, configured with the WEB communication interface. It is convenient to network with the electric furnace.
