Description
Technical field
The present invention relates to a kind of methods for improving blast furnace crucibe oxygen gesture using cinder monkey, belong to blast furnace smelting technology neck
Domain.
Background technique
During blast furnace process high-titanium type vanadium-titanium magnetite, reduce in the rate of oxygen of the following ore of blast furnace melting with soft, titanium
Reduction increases, and is conducive to the generation of TiCN, the generation of TiCN directly influences the performance of clinker, makes clinker retrogradation, be unfavorable for slag
Iron separation.The study found that improving FeO, MnO, CaF in slag2Equal size is conducive to improve blast cylinder oxygen gesture.In the past in Panzhihua height
Cupola well oxygen gesture is improved using the blowing special blows air of mouth in furnace production, furnace structure and safety are adversely affected, rear
It is cancelled in the design come.And in recent years, due to the raising of feed grade, the quantity of slag reduces and the more iron mouths of blast furnace and tapping side
The change of formula, the cinder notch for being used to discharge clinker originally do not use substantially.
In recent years since raw material and fuel quality fluctuation is big, operating adjustment parameter is explored unreasonable under the conditions of intensification of smelting process in BF,
Cause conditions of blast furnace stable smooth operation be deteriorated, abnormal conditions, which occurs, in crucible state to be increased, it has to blowing out to cupola well carry out investigation and
Processing, investigation show that the main reason for furnace cylinder working situation is abnormal is still the TiCN too high levels deposited in cupola well, Active hearth condition
Degree is inadequate, leads to cupola well edge bonding, center accumulation.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of side for improving blast furnace crucibe oxygen gesture using cinder monkey
Method can effectively improve blast furnace crucibe oxygen gesture.
To solve above-mentioned technical problem the technical scheme adopted by the invention is that: using cinder monkey improve blast furnace crucibe oxygen
The method of gesture is disposed with injection pipeline in cinder monkey, medium is blown into furnace by injection pipeline, blowing media is to compress sky
Based on gas, it is aided with granular soild oxide or CaF2Or the composition of above-mentioned solid matter, jetting pressure are
0.8MPa to 1.0MPa, by volume percentage, wherein solid matter flow is the 8% to 10% of air quantity.
Further, the cooling water pipe inlet and outlet of cinder monkey are provided with temperature sensor.
Further, cinder monkey front is provided with a grade slag wall.
Further, blast furnace casting mode is continuous uninterrupted tapping.
Further, injection pipeline uses water cooling cast steel casing, the cooling water pipe of injection pipeline is wound in the shape of a spiral
Injection pipeline outer wall.
Further, injection pipeline includes horizontal segment, the inclining positioned at cinder monkey outer end positioned at cinder monkey inner end
Oblique section, the end of tilting section are to tilt down relative to its front end, and inclination angle with respect to the horizontal plane is 8 ° to 10 °, injection tube
The internal diameter in road is 16mm to 20mm.
Further, soild oxide includes the combination of FeO or MnO or both.
The beneficial effects of the present invention are: being blown soild oxide or CaF by cinder monkey2, increase cupola well oxygen gesture, it is right
Cupola well is enlivened with important value；And blast furnace existing structure is utilized, to furnace structure and safety there is no adversely affecting, is implemented
It is convenient.
