Description
Technical field
Blast furnace ironmaking simulation test device is the utility model is related to, more particularly to one kind is used for analog blast furnace cupola well molten iron
The device of water drippage.
Background technology
Cupola well is the key position for determining the life of the blast furnace.The erosion of cupola well can generally go out from thermal conduction study and hydrodynamics
Explanation is sent, molten iron current have certain corrosion function to cupola well bottom lining.In the middle part of cupola well, in tuyere area and shaft under
, there is the space that a coke is declined with extremely slow speed, the accumulation of coke herein in portion, this coke briquette is referred to as dead material
Post.In the case of cupola well fills with slag iron water, being influenceed by dead stock column and the process of tapping a blast furnace, slag iron water directly impacts the hot face of cupola well furnace bottom,
It is difficult to form stable speed and temperature boundary layer in the hot face of cupola well furnace bottom.In order to which hot slag iron water is reduced or avoided to cupola well stove
Bottom is washed away, it is necessary to which research causes the reason for slag molten iron flow inside cupola well, to extend the blast furnace hearth and bottom life-span.
Except molten iron current to cupola well furnace bottom wash away erosion in addition to, molten hot metal from the drippage process of upper blast furnace for
Slag molten iron flow also has a significant impact inside blast furnace crucibe, therefore, it is necessary to the drippage to molten hot metal in blast furnace production process
Process is studied.Due to 1500~1600 DEG C or so high temperature inside blast furnace, condition of work is severe, can not implement to monitor, can only
Drippage process of the molten hot metal in blast furnace crucibe is studied using the means of physical analogy.
It is domestic at present less to the experimental study report of blast furnace crucibe molten hot metal drippage process for application simulation means,
And without unified experimental program and experimental standard is proposed, the drippage process study for being primarily due to blast furnace crucibe molten hot metal relates to
And factor it is more, it is necessary to which covering experimental provision or kinds of experiments method could be studied more, workload and experimental cost are larger,
It is unfavorable for researcher to be in full swing research work.Opinions vary for the external PHYSICAL MODELING OF IN in terms of blast furnace crucibe,
For the field being each concerned about and problem design by self model, different hypothesis is proposed during designing a model simultaneously
Different influence factors is have ignored, does not form unified experimental method and specification so far, the knot obtained for different experiments
Fruit can not mutually quote, corroborate each other, and cause substantial amounts of repetition research and the wasting of resources.
Notification number is that CN203981374U Chinese patent discloses " a kind of blast furnace crucibe molten iron flow analogue means ", is wrapped
Include plexiglass box, top cover, water distributor, conductivity measurement, data acquisition unit and by metal framework, gauze and hard
The dead stock column of matter ball composition.The device can simulate the flow regime of molten iron in blast furnace crucibe on the whole, understand State of Blast Furnace
Dead stock column floating state in cylinder, theoretical foundation is provided to cupola well wall and washing away for cylinder bottom to mitigate molten iron.But the device is simultaneously
The drippage process of molten hot metal can not fully be reflected, when flow control is in the case of relatively low, it may appear that molten hot metal is from model
Uneven phenomenon is dripped on top, when uneven drippage stock column, the flowing to molten iron in cupola well till death of molten hot metal can produce not
Profit influences, it is impossible to the fully actual conditions of reflection blast fumance, causes analog distortion.
Notification number is CN102925601A Chinese patent, discloses " a kind of iron-containing charge high temperature soft melting dropping characteristic
Evaluation method ", includes the division of iron-containing charge soft melting dropping temperature range, the computational methods of the performance trait value in each section and
