Description
Technical field
The utility model belongs to metallurgical equipment manufacturing field and STEELMAKING PRODUCTION equipment, is specifically related to a kind of LF ladle refining furnace and feeds silk liner online.
Background technology
Feeding silk is a kind of ladle refining techniques occurred late 1970s.The multiple alloys such as Ca-Si, rare earth alloy, aluminium, ferro-boron and ferrotianium or additive are made cored-wire by it, molten steel depths is added by the method for machinery, to steel liquid deoxidation, desulfurization, carry out the refining treatment such as non-metallic inclusion denaturing treatment and alloying, to improve metallurgical process, improve the purity of steel, the use properties of optimizing product, reduces processing cost etc.Existing silk technology of feeding needs to arrange special wire feeder platform, malfunction, and maintenance is inconvenient and cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is, feeds silk above shortcomings, provides that a kind of cost of investment is low, structure is simple, operation maintenance is convenient, LF ladle refining furnace that is long service life feeds silk liner online for existing.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of LF ladle refining furnace feeds silk liner online, comprise wire feeder, fixed guide pipe, water cold sleeve and ladle, described water cold sleeve is arranged on the cover of ladle, fixed guide pipe bottom linearly section and inserting in water cold sleeve, and flush along with edge under water cold sleeve under fixed guide pipe, fixed by Flange joint with water cold sleeve in the middle part of fixed guide pipe, fixed guide pipe top is bending and the inlet wire introducing port on top is set to horn-like; The side of described wire feeder is provided with level and feeds fiber tube, and described level feeds the horn-like inlet wire introducing port that fiber tube faces fixed guide pipe, and level is fed and kept certain level gap between fiber tube and the horn-like inlet wire introducing port of fixed guide pipe.
By such scheme, described fixed guide pipe bending radius is more than or equal to 1000mm.
By such scheme, it is 50 ~ 80mm (preventing fixed guide pipe from interfering with hello fiber tube with rocking during tank lid lifting) that described level feeds the horizontal clearance kept between fiber tube and the horn-like inlet wire introducing port of fixed guide pipe.
By such scheme, the straight-line segment of described fixed guide pipe is provided with ring flange one, and water cold sleeve port is provided with ring flange two, and the ring flange one of fixed guide pipe and the ring flange two of water cold sleeve are by being bolted together.
Principle of work of the present utility model: when feeding silk, fixed guide pipe one end faces the alloy wire outlet of level hello the fiber tube of wire feeder, and one end puts in water cold sleeve, and alloy wire is sent at a high speed by wire feeder, is led, finally penetrate molten steel face by fixed guide pipe.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model structure is simple, and cost of investment is low; Wire feeder is directly arranged on LF refining furnace service platform, does not need design wire feeder platform, flexible and convenient operation;
2, fixed guide pipe bottom is inserted in water cold sleeve, strengthens the cooling of fixed guide pipe, fixed guide pipe long service life;
3, the level of wire feeder feeds fiber tube not by slag and the high temperature scaling loss of splashing in production process, avoids the problem that the level changing wire feeder feeds fiber tube; Change fixed guide pipe time, only the bolt of the ring flange two of the ring flange one and water cold sleeve that are connected and fixed guide pipe need be backed out, again new fixed guide pipe is inserted water cold sleeve to tighten, whole Renewal process only needs 3-5 minute, shorten the treatment time, reduce labor strength, significantly improve working efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model;
In figure: 1-wire feeder, 2-level feed fiber tube, 3-fixed guide pipe, 4-water cold sleeve, 5-cover, 6-ladle, 7-ring flange one, 8-ring flange two.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further.
As shown in Figure 1, LF ladle refining furnace described in the utility model feeds silk liner online, comprise wire feeder 1, fixed guide pipe 3, water cold sleeve 4 and ladle 6, described water cold sleeve 4 is arranged on the cover 5 of ladle 6, fixed guide pipe 3 bottom linearly section and inserting in water cold sleeve 4, and the 4 times edges in fixed guide pipe 3 times edges and water cold sleeve flush, fixed by Flange joint with water cold sleeve 4 in the middle part of fixed guide pipe 3, fixed guide pipe 3 top is bending and the inlet wire introducing port on top is set to horn-like; The side of described wire feeder 1 is provided with level and feeds fiber tube 2, described level feeds the horn-like inlet wire introducing port that fiber tube 2 faces fixed guide pipe 3, and level feeds the horizontal clearance keeping 50 ~ 80mm between fiber tube 2 and the horn-like inlet wire introducing port of fixed guide pipe 3, rock when preventing fixed guide pipe 3 to be elevated with cover 5 and interfere with level hello fiber tube 2.
During for reducing to feed silk, alloy wire is by the resistance of fixed guide pipe, and described fixed guide pipe 3 bending radius is more than or equal to 1000mm.
The straight-line segment of described fixed guide pipe 3 is provided with ring flange 1, water cold sleeve 4 port is provided with ring flange 28, together with the ring flange 1 of fixed guide pipe 3 is bolted with the ring flange 28 of water cold sleeve 4, achieve fixed guide pipe 3 and cover 5 one lifting.
When feeding silk, fixed guide pipe 3 one end faces the alloy wire outlet of level hello the fiber tube 2 of wire feeder 1, and one end puts in water cold sleeve 4, and alloy wire is sent at a high speed by wire feeder 1, is led, finally penetrate molten steel face by fixed guide pipe 3; When changing fixed guide pipe 3, only the bolt of the ring flange 28 of the ring flange 1 and water cold sleeve 4 that are connected and fixed guide pipe 3 need be backed out, newer fixed guide pipe 3 is inserted water cold sleeve 4 tighten.
