Description
Technical field
The present invention relates to liquid steel refining technical fields, especially a kind of wire feeder for liquid steel refining.
Background technology
Liquid steel refining uses metal wire-feeding technique, and metal or alloy pulvis, which is formed wire, by wire feeder is sent into molten bath
Depths is melted rapidly in molten bath, dissolves and is reacted.Currently, wire feeder is all fed using hanging liquid steel level mode, this side
Formula can meet the feeding requirement of most wires, but for some easy scaling loss and noble element, such as calcium, rare earth, titanium etc.,
By the way of hanging liquid steel level, a part is just vapored away on the top of liquid steel level, causes the waste rate of wire high, gold
Belong to the utilization rate of silk between 8%~23%, utilization rate is relatively low and stability is poor, improves the cost and efficiency of liquid steel refining.
Invention content
Technical problem to be solved by the invention is to provide a kind of wire feeders for improving wire utilization rate.
The present invention solves the wire feeder that liquid steel refining is used for used by its technical problem, including feeds silk conduit, described to feed
The middle and upper part of silk conduit is provided with stomata, further includes air supply plant, the air supply plant includes snorkel, the snorkel and gas
Hole is connected.
Further, the diameter for feeding silk conduit is gradually reduced from top to bottom, maximum gauge is the 2-4 of wire
Times, minimum diameter is 1.2-1.8 times of wire.
Further, the lower part for feeding silk conduit is detachably connected with the middle and upper part for feeding silk conduit.
Further, the lower part suit for feeding silk conduit is provided with columnar refractory material protective layer.
Further, the quantity of the stomata is at least two.
Further, further including sealing ring, the sealing ring is arranged at the top for feeding silk conduit.
Further, the sealing ring is up big and down small circular platform type.
The beneficial effects of the invention are as follows：The present invention is provided with air supply plant, and stomata is arranged on silk conduit in feeding for wire feeder,
When liquid steel refining, after the inert gas for carrying pressure to feeding the input of silk conduit by air supply plant, the lower part that will feed silk conduit is deep
Enter under molten steel face at 100-200mm, then wire is passed through to feeding silk conduit, under the action of the inert gas with pressure, gold
Belong to silk to enter in molten steel, be directly used in smelting molten steel, the mode refined molten steel that immersion feeds wire is realized, with pressure
Inert gas prevents molten steel to enter and feeds silk conduit and ensure that wire can enter in molten steel, reduces the waste of wire,
By largely putting into practice and testing, wire feeder using the present invention, between 27-41%, utilization rate obtains the utilization rate of wire
It significantly improves, stability is improved, and reduces the cost and efficiency of liquid steel refining.
Description of the drawings
Fig. 1 is the structural schematic diagram that the present invention feeds silk conduit；
Parts, position and number in figure：Feed silk conduit 1, stomata 11, refractory material protective layer 2, sealing ring 3, wire
4。
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the present invention is used for the wire feeder of liquid steel refining, including silk conduit 1 is fed, it is described to feed in silk conduit 1
Top is provided with stomata 11, and the quantity of stomata 11 is at least two, further includes air supply plant, and the air supply plant includes snorkel,
The snorkel is connected with stomata 11.
Air supply plant is used for feeding inert gas, such as nitrogen, argon gas etc. of the input of silk conduit 1 with pressure, and pressure is
Between 0.1-0.15Mpa.It, will after the inert gas for carrying pressure to feeding the input of silk conduit by air supply plant when liquid steel refining
The lower part for feeding silk conduit 1 is goed deep under molten steel face at 100-200mm, then is passed through wire 4 to feeding silk conduit 1, and wire 4 can be gold
Belong to calcium silk, Titanium silk, the wire 4 into molten steel is directly used in smelting molten steel, realizes the mode that immersion feeds wire 4
Refined molten steel, the inert gas with pressure prevent molten steel to enter and feed silk conduit 1 and ensure that wire 4 can enter molten steel
In, the waste of wire 4 is reduced, by largely putting into practice and testing, wire feeder using the present invention, the utilization rate of wire 4
Between 27-41%, utilization rate is significantly improved, and stability reaches raising, reduces the cost and efficiency of liquid steel refining.
Specifically, when liquid steel refining, wire 4 is vertical feeding silk conduit 1, in order to ensure that wire 4 can be smooth
Into in molten steel, it is funnel-form to feed silk conduit 1, and the diameter for feeding silk conduit 1 is gradually reduced from top to bottom, and maximum gauge is metal
2-4 times of silk 4, minimum diameter is 1.2-1.8 times of wire 4.Lower part due to feeding silk conduit 1 will be directed into molten steel,
It is influenced very greatly, to need to be replaced frequently, is preferably detachably connected the lower part for feeding silk conduit 1 and the middle and upper part for feeding silk conduit 1,
The lower part for only needing to change and feeding silk conduit 1 is replaced, production cost is reduced.Further, also installing can be covered in the lower part for feeding silk conduit 1
It is equipped with columnar refractory material protective layer 2, refractory material protective layer 2 is used to protect the lower part for feeding silk conduit 1.
Gas causes molten steel to enter and feeds 1 lower part of silk conduit, feeding silk conduit 1 from feeding silk conduit 1 top leakage in order to prevent
Top be provided with sealing ring 3, and sealing ring 3 is up big and down small circular platform type, and sealing ring can be close to wire when work, reduce
Gas leakage, while preventing the addition of the influence wire 4 of sealing ring 3.
