The device can charge the materials in the turndown directions of steel and slag discharging, so that the materials are charged uniformly, and the slagging effect is guaranteed; pressed slag materials are uniformly charged, so that the damage of overflowed molten steel to a rail and equipment below a furnace can be avoided, and the personal safety is guaranteed; and when the materials are charged during turndown, a furnace lining is uniformly heated and protected, the service life of the furnace lining is prolonged, the refractory materials of the furnace lining are saved, and the great loss caused by runout can be avoided.
Description
Technical field
The utility model relates to a kind of feeding device of iron alloy smelting furnace, belongs to the steelmaking equipment technical field.
Background technology
The adding mode of iron alloy smelting furnace alloy material has two kinds, and first kind for reinforced behind the bell of outwarding winding, and second kind for to feed in raw material through the charge cavity on the bell.The reinforced program of outwarding winding behind the bell is complicated, and electrode needs to have a power failure, promote, and is prone to cause dissipation of heat energy, and general at present the employing fed in raw material through the charge cavity on the bell.But in process of production,, can not satisfy, cause burden distribution inhomogeneous, influence the slag making effect tapping, feeding in raw material when slagging tap turndown for the charge cavity that this feed way designed can only could feed in raw material when stove is in vertical position; Owing to press can not evenly adding of slag charge, might cause molten steel excessive simultaneously, damage track and equipment under the stove, security incident takes place; And when turndown, can not feed in raw material, it is inhomogeneous that furnace lining is heated, and reduced the life-span of furnace lining, and runout might take place, the massive losses that brings.
The utility model content
The utility model technical problem to be solved provides a kind of reinforced device of ability turndown that can tap, feed in raw material when slagging tap two turndown directions.
The technical scheme that solves the problems of the technologies described above is:
The reinforced device of a kind of ability turndown, it comprises center bell, charge cavity, water cooled cover, on the bell of center, is evenly equipped with 3 electrode holes; Its improvements are, its loading hopper is made up of rotation elephant trunk, middle hopper, fixed slide pipe, and the lower end of fixed slide pipe is connected with charge cavity; The upper end of fixed slide pipe connects middle hopper, and the rotation elephant trunk is installed in the upper end of middle hopper, and the bottom of rotation elephant trunk is connected with the middle hopper vertical fixing; The top of rotation elephant trunk is to a lateral buckling, and middle hopper is a rectangular parallelepiped, or cylinder; Or elliptical cylinder, the horizontal section of middle hopper is greater than the circumferential section of fixed slide pipe and charge cavity.
The reinforced device of above-mentioned ability turndown, for being rotatably connected, the angle between top bending part and the lower vertical part is greater than 90 degree between the top bending part of said rotation elephant trunk and the lower vertical part.
The reinforced device of above-mentioned ability turndown; Said charge cavity is between two electrode holes of center bell; With two electrode hole equidistance, the minor increment at charge cavity margin and center bell center is greater than the distance at electrode hole Center-to-Center bell center, and the diameter of charge cavity is less than the diameter of electrode hole.
The usefulness of the utility model is:
The utility model has improved the position of feeding device and the shape of loading hopper, has solved in tapping, the reinforced problem of two the turndown directions of slagging tap.Guarantee to feed in raw material evenly, guaranteed the slag making effect; Press the even adding of slag charge simultaneously, prevent track and equipment under the excessive damage stove of molten steel, guarantee personnel safety; Reinforced when turndown, furnace lining is heated evenly, protected furnace lining, prolonged furnace lining life-span, practiced thrift the anti-material of furnace lining, prevent the massive losses that runout brings.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Mark is following among the figure: rotation elephant trunk 1, middle hopper 2, fixed slide pipe 3, charge cavity 4, water cooled cover 5, center bell 6, electrode hole 7.
Embodiment
Show among the figure that the utility model improves loading hopper.
Loading hopper is made up of rotation elephant trunk 1, middle hopper 2, fixed slide pipe 3.Middle hopper 2 is connected between fixed slide pipe 3 and the rotation elephant trunk 1, and the lower end of fixed slide pipe 3 is connected with charge cavity 4, and the top of rotation elephant trunk 1 is to a lateral buckling.When reinforced, furnace charge is added middle hopper 2, through fixed slide pipe 3, charge cavity 4 furnace charge is added positions different in the iron alloy smelting furnace again through rotation elephant trunk 1.
Show among the figure that middle hopper 2 is a rectangular parallelepiped, or cylinder, or other geometrical shapies such as elliptical cylinder, the horizontal section of middle hopper 2 is greater than the circumferential section of fixed slide pipe 3 and charge cavity 4.
Show among the figure that rotation elephant trunk 1 is two body structures, its bottom is a straight tube; Be connected with the upper surface vertical fixing of middle hopper 2; Its top is to a lateral buckling, and for being rotatably connected, the angle between bending top and the vertical lower is greater than 90 degree between the upper and lower part.
After adopting this structure, be in slagging tap, tapping during state of heeling condition, can rotation elephant trunk 1 be rotated at body of heater; The feeding mouth of rotation elephant trunk 1 is made progress; Promptly can in body of heater, feed in raw material, the volume of middle hopper 2 is bigger, can hold more material; Make even pan feeding when feeding in raw material, avoid suspending and interrupted pan feeding.
Show among the figure; Improve the position of the utility model charge cavity 4, and the position of original charge cavity 4 by changing into now on center bell 6 on the water cooled cover 5, can be added the electrode of iron alloy smelting furnace near the hot-zone with furnace charge like this; Guarantee that furnace charge can add the hot-zone of stove; Quickened furnace charge fusing, make molten steel composition even, prolonged furnace lining life-span, practiced thrift the anti-material of furnace lining, guaranteed that the operative employee can observe the furnace lining situation.
