Abstract
A kind of for ferronickel processing AOD furnace, including body of heater, hang beam and drive motor, connected by hinge arrangement above described body of heater and have upset feeding bin, connect with body of heater bottom described upset feeding bin, by bearing block, anti-blocking axle is installed with above body of heater communicating position in described upset feeding bin, described anti-blocking axle top extends to overturn outside feeding bin, is rotated by gear-box and driven by motor.This utility model overcomes the deficiencies in the prior art, feeding bin is hinged with body of heater, feeding bin feeding port obliquity is automatically controlled by stretching structure, the anti-blocking axle of spiral is set in feeding bin simultaneously, prevent that indivedual raw material block is excessive causes feed opening to block, simple in construction, feeding is convenient, and the scope of application is wide.
Description
Technical field
This utility model relates to AOD furnace technical field, particularly belongs to a kind of for ferronickel processing AOD furnace.
Background technology
AOD furnace is the refining equipment of argon oxygen decarburizing process, with the abbreviation letter designation of this method English name.Its profile and converter
Approximation, body of heater is placed on a backing ring that can front and back tumble, pin fixes；In the bottom side of stove equipped with to molten bath water
Square to being blown into the spray gun of gas, the quantity of spray gun is different according to the tonnage of stove, generally 2～3；Spray gun extended
The meeting point of line overlaps with the vertical pivot of stove.Spray gun is made up of inner tube (copper) and outer tube (rustless steel) two-layer, and inner tube imports main
Blowing gas is (by ArO2.Or Ar-N2 composition), the annulus between inner tube and outer tube imports Ar, N2 or air plays cooling and makees
In order to protect spray gun.Spray gun is deflection type, imbeds refractory masses when brickwork, burning Tong Bu with furnace lining in smelting process
Damage.The oxygen being blown into is mainly used for carbonoxide and heats up, and the argon being blown into is mainly strong convection stirring, also produces high nitrogen alloy
Time can carry out nitrogen flushing and carry out alloying, be can to carry out rushing nitrogen, this saves in the steel grade of basic production 21-4N class
A lot of metal nitrides, as nitrogenized the addition of network, save a lot of production cost.
Body of heater magnesia-calcium brick or chromium and magnesium brick or rich conite brick masonry；Quality higher electric smelting chromium is used around spray gun
Magnesia brick is built by laying bricks or stones, washes away bearing high temperature and molten steel；Movable furnace crown chromium and magnesium brick or alumina-magnesia brick are built by laying bricks or stones, it is also possible to use heat-resisting coagulation
Soil pouring；The dimension scale of burner hearth is substantially: pool depth: furnace diameter: burner hearth height overall-1: 2: 3；Stove is at certain angle of leaning forward
In the case of degree, transfer ladle pouring first water of making steel into, now gas spray gun is in more than molten steel face；Stove returns to orthostatism
When putting, spray gun submerges molten steel depths, starts blowing refining；After refine completes, still tap through furnace crown.
Utility model content
The purpose of this utility model there is provided one and processes AOD furnace for ferronickel, overcomes the deficiencies in the prior art, will
Feeding bin is hinged with body of heater, automatically controls feeding bin feeding port obliquity by stretching structure, sets in feeding bin simultaneously
Putting the anti-blocking axle of spiral, prevent that indivedual raw material block is excessive causes feed opening to block, simple in construction, feeding is convenient, and the scope of application is wide.
For solving the problems referred to above, technical solution adopted in the utility model is as follows:
A kind of for ferronickel processing AOD furnace, including body of heater, hang beam and drive motor, by hinge above described body of heater
Chain structure connects upset feeding bin, connect with body of heater bottom described upset feeding bin, and described upset feeding bin is interior and stove
Being provided with anti-blocking axle by bearing block above body communicating position, described anti-blocking axle top extends to overturn outside feeding bin, logical
Cross gear-box and driven by motor rotates.
Further, it is provided with spiral lamina outside described anti-blocking axle.
Further, described upset feeding bin side is hinged and is connected to stretching structure, the described stretching structure other end and stove
Body is hinged.
Further, described stretching structure is cylinder or hydraulic cylinder.
Compared with prior art, implementation result of the present utility model is as follows for this utility model:
One described in the utility model processes AOD furnace for ferronickel, is hinged with body of heater by feeding bin, passes through stretching structure
Automatically control feeding bin feeding port obliquity, the anti-blocking axle of spiral is set in feeding bin simultaneously, prevents indivedual raw material block excessive
Causing feed opening to block, simple in construction, feeding is convenient, and the scope of application is wide.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited only to these examples, for de-
On the premise of present inventive concept, within any improvement of doing all falls within protection scope of the present invention.
As it can be seen, one described in the utility model processes AOD furnace for ferronickel, including body of heater 1, hang beam 2 and drive
Galvanic electricity machine 3, above described body of heater 1 by hinge arrangement 4 connect have upset feeding bin 5, bottom described upset feeding bin 5 with
Body of heater connects, and is provided with anti-blocking axle 7 with above body of heater communicating position by bearing block 71 in described upset feeding bin 5, described
To extend to overturn feeding bin 5 outside on anti-blocking axle 7 top, be rotated by gear-box 81 and motor 8；Outside described anti-blocking axle
Portion is provided with spiral lamina；Described upset feeding bin 5 side is hinged and is connected to stretching structure 6, described stretching structure 6 other end and stove
Body 1 is hinged；Described stretching structure 6 is cylinder or hydraulic cylinder.
