Chinese patent discloses before a kind of electric furnace the ladle current-following inoculation device (CN202779633U) that taps a blast furnace, it comprises the bunker mechanism that stores random inoculant, fixed mechanism and topple over operating mechanism, bunker mechanism comprises material stock box and the hopper that is arranged on material stock box bottom and communicates with material stock box, bucket front has material mouth, fixed mechanism comprises fixed bar and is arranged on the clamp of fixed mount one side for being connected with casting ladle, hopper and clamp top are hinged, topple over operating mechanism and comprise action bars and the actuator being connected with action bars, actuator is connected with material stock box and controls material stock box and recedes.Although this device can make inovulant evenly be added on flowing molten iron, thereby having improved molten steel preparation effect, there is complex structure in this device, and manufacturing cost is high, and the technical problem such as take up room large.
Summary of the invention
The utility model has mainly been to provide a kind of simple in structure, low cost of manufacture, save space, stokehold, can make inovulant can be fully, mix with the molten iron of coming out of the stove uniformly, thereby guaranteed the stream inoculation device for electric furnace of molten steel preparation quality, solved the electric furnace molten steel preparation apparatus structure complexity existing in prior art, manufacturing cost is high, and the technical problem such as take up room large.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of stream inoculation device for electric furnace, comprise that body of heater and button cover on the bell on body of heater, on the body of heater port mating with bell, be outward extended with converter nose, on the bell sidewall corresponding with described converter nose, extend and be provided with discharge nozzle, end face at bell is provided with holding tank, the medial extremity of discharge nozzle is connected with holding tank through bell sidewall, and the outboard end of discharge nozzle is to downward-extension the vertical axis that points to converter nose.By the holding tank of storage inovulant is set on the bell of electric furnace, and the connection discharge nozzle that stretches out in holding tank, because the external port of discharge nozzle is corresponding with the converter nose on body of heater, converter nose is half arcuate structure of opening upwards, the axis of converter nose is vertically pointed in the outlet of discharge nozzle, during use, body of heater leans forward in converter nose direction, molten iron flows out from converter nose, inovulant in holding tank flows out from discharge nozzle, with molten iron, enter in molten iron pouring ladle, inovulant can be fully, mix with the molten iron of coming out of the stove uniformly, thereby guaranteed molten steel preparation quality, overall structure is simple, make full use of the self structure of bell, low cost of manufacture, and saved space, stokehold.
As preferably, the cross section of described holding tank is water-drop-shaped, and the miner diameter end of the holding tank of water-drop-shaped is towards converter nose.The holding tank of water-drop-shaped is beneficial to inovulant and automatically collects to discharge nozzle when bell leans forward, and guarantees that inovulant evenly flows out smoothly.
As preferably, on the opening of described holding tank, be provided with hopper mouth half door, hopper mouth half door is located on holding tank opening corresponding to converter nose side.Hopper mouth half door is set on the opening of holding tank, seal part holding tank opening, not only meet the requirement of dosing inovulant, and because hopper mouth half gear is on holding tank opening corresponding to converter nose side, guarantee can stop that the inovulant in holding tank overflows from holding tank outward opening by hopper mouth half door when bell leans forward.
As preferably, on described discharge nozzle, be provided with shutoff valve.The convenient time of dosing and the amount of filling of controlling inovulant of shutoff valve.
As preferably, described discharge nozzle is L-shaped, and corresponding to the axis coplanar of L shaped discharge nozzle widthwise edge and converter nose, the longitudinal edge of L shaped discharge nozzle points to the axis of converter nose vertically downward.When the discharging opening of discharge nozzle points to the axis of converter nose vertically downward, discharging opening keeps vertical with converter nose, has guaranteed that the drop point of inovulant is all positioned on the flowing molten iron at converter nose place, thereby has avoided not with flow phenomenon, has further guaranteed the quality that breeds of molten iron.
Therefore, stream inoculation device for electric furnace of the present utility model has following advantage: for the holding tank that stores inovulant, be positioned at bell, take full advantage of self space of bell, simple in structure, by discharge nozzle, inovulant is led to the top of converter nose, low cost of manufacture, and saved space, stokehold, the discharging opening of discharge nozzle is the straight bend pipe pointing on converter nose flowing molten iron, has guaranteed to breed drop point constant, make inovulant can be fully, mix with the molten iron of coming out of the stove uniformly, thereby guaranteed molten steel preparation quality.
