Description
Technical field
The utility model relates to accurately load and draw in particular to a kind of large ladle furnace in smelting molten steel equipment technical field
Quicksand device.
Background technique
Ladle draining sand is necessary material in STEELMAKING PRODUCTION, and ladle needs ladle draining sand being packed into ladle before containing molten steel
The mouth of a river goes out, and stuffing sand is generally launched when pouring steel, and molten steel also flows out therewith simultaneously, realizes that nature opens the process of pouring.It is added at present toward ladle
Stuffing sand mode mostly uses the method manually put into, i.e., artificial toward throwing stuffing sand, each average input at hot steel ladle sliding water gap
2.5 bags of stuffing sands, to guarantee that continuous casting just normally opened can pour.
Since manually to throwing stuffing sand at hot steel ladle sliding water gap, the accuracy of investment is not high, increase stuffing sand consumption,
Cost is increased simultaneously.Due to adding also to increase nonmetallic inclusionsin steel content into drainage agent into ladle, reduce
Molten steel clarity, declines the internal soundness of steel.Former Adding Way keeps ladle automatic free-opening rate low, increases artificial burning oxygen
Number increases production cost, reduces the internal soundness of steel, while being also easy to produce scald accident, and more important is burn oxygen number
Increase, be easy to cause continuous casting is disconnected to pour, influences that continuous casting is continuous, stablizes, balanced production.
Utility model content
(1) technical problems to be solved
The present invention aiming at above-mentioned plus stuffing sand there are the problem of, proposition training for sediment pipe adds the mode of counterweight, makes to be added to
Stuffing sand at steel ladle sliding water gap can reduce the amount for adding stuffing sand accurately in place.The utility model overcomes in the prior art
Steel mill is because ladle is small-sized, and the short light quality of training for sediment pipe is in operation, but this lightweight training for sediment pipe can not be suitable for large size
Ladle precisely loads the shortcomings that stuffing sand.Technology to be solved in the utility model, which is to provide one kind, can be used in large ladle furnace
It is accurate to load drainage sand device, the loss of stuffing sand is reduced, worker's scald accident is reduced.
(2) technical solution
In order to solve the above-mentioned technical problem, the utility model provides such a large ladle furnace and accurately loads stuffing sand dress

Preferably, exhaust passage is provided on the side wall of the training for sediment pipe.
Preferably, the training for sediment pipe is inclined at the inside of the ladle.
Preferably, the magnetic patch that the counterweight is detachably stacked by ten pieces is constituted.
(3) beneficial effect
The utility model overcomes the prior art kelp during cultivation because be directly exposed in seawater, be easy because
Environmental factor leads to the shortcomings that losing and being unfavorable for centralized recovery.Steel-making plus drainage agent are that previous processes are using artificial investment
Method, i.e., it is artificial toward 2.5 bags of drainage agents of each average input at slide gate nozzle.Training for sediment pipe is now promoted to sliding water using pulley
Drainage agent is filled at mouthful, new process averagely fills 0.7 bag of drainage agent every time can.The new process and modification scheme test 3000
Furnace, successfully sizing production.It adopts new technology plus drainage agent has following benefit:
1, every furnace can save 1.8 bags of drainage agent, every bag 34.5 yuan of drainage agent, then every furnace save the cost be 1.8 Dai ∕ furnaces ×
∕ bags=62.1 Yuan ∕ furnace of 34.5 Yuan
Former continuous casting casting rate only has 61.23%, and continuous casting casting rate can be improved using this method and reach 87.8% or more, subtract
Continuous casting is lacked and has burnt oxygen number, has saved and burn oxygen pipe, reduce by 10 Yuan ∕ furnace of cost.
It counts every furnace and is total to+10 furnace=72.1 yuan Yuan ∕ of 62.1 Yuan ∕ furnace of save the cost.
It is assumed that 52 furnaces of average daily production, then year cost-saved 52 Lu ∕ days × furnace × 330 day 72.1.1 Yuan ∕=
123.72 ten thousand yuan.
0.6 ten thousand yuan of improvement expenses, then 123.12 ten thousand yuan of year pure wound benefit.
2, since drainage agent is added less into ladle, also just reduce nonmetallic inclusionsin steel content, improve molten steel
Clarity improves steel quality.
3, oxygen number is burnt due to reducing, also just reduces the probability of worker's scald.
4, most importantly due to improving continuous casting casting rate, also just reduce continuous casting disconnected a possibility that pouring, connect for continuous casting
Continuous, stable, balanced production creates condition.
