Description
Technical field
The utility model is related to a kind of steel making equipment, relates in particular to a kind of blast furnace, more particularly to a kind of high
Furnace charge layer measurement apparatus.
Background technology
During blast furnace ironmaking, furnace charge is loaded in stove by " the no bell " of furnace roof, by means of the hot blast blasted of bottom house, is led to
Cross combustion of coke and produce heat and carbon monoxide, on the one hand heating furnace charge, on the other hand reduction furnace charge, so as to realize the pig iron just
Often production.The smelting process of blast furnace is also to be adjusted by cloth and air blast parameter simultaneously.By adjusting in blast furnace operating
Whole cloth doses, cloth order, the control measure such as furnace charge drop point, can regulate and control the distribution of Gas Flow inside blast furnace, thus control CO,
CO2、H2Deng the distribution in stove, on the one hand distribution of the control heat in stove, on the one hand two control different parts in stove
Reaction speed is learned, and then realizes the functions such as the optimization of blast fumance, troubleshooting.
General during cloth to load two kinds of furnace charges, coke and ore from furnace roof, coke individually loads as fuel, and ore is general
Including sintering deposit, pellet, lump ore, it is fitted into together in blast furnace after mixing in batch can.Current nearly all large blast furnace is all
It is to use that furnace charge is distributed into stove without clock apparatus for distributing, realizes the loading of furnace charge, this equipment is in different angles position by chute
The different number of turns are rotated gradually furnace charge is distributed into stove to realize.
After furnace charge loads in stove, ore and coke can form certain stratiform bed of material, and be formed along blast furnace radial direction
Certain thickness, can typically form the shape of charge level of marginal belt platform.Combustion of coke produces heat and carbon monoxide in burner hearth in stove
Interior formation air-flow, because of cloth species and the difference of cloth doses, coke is different along radial direction formation thickness in furnace roof with ore
Distribution, and air current flow is influenceed by bed of material granularity and thickness.Ore grain size is small, than great, and the thickness of feed layer of formation is big
Place it is also big to the resistance of Gas Flow, that is to say, that the different-thickness of ore layer and coke layer actually represent it to coal gas
The different resistances of stream.The general thickness ratio with ore and coke layer in production, i.e. O/C ratios are used as the adjustment of blast furnace roof air-flow
A kind of judgment criteria.
In blast furnace operating, O/C than distribution directly determine blast furnace air flow method, this parameter to blast furnace operating to close
It is important.But O/C ratios are difficult to accurately calculate in actual blast furnace operating, mainly due to the charge level shape formed after the complete coke of cloth
Shape, during follow-up cloth ore deposit, because ore impulsive force is big, when falling on the coke layer being made up of bulk cargo, coke layer can collapse
Fall, this slump can destroy the coke shape of charge level formed before the follow-up ore deposit of cloth, so that real O/C can not be obtained than being distributed, its
Key problem is exactly the situation of slump amount, slump position, coke and the ore mixing of dully knowing furnace charge.Document " Kim L
Hochings, John M Burgess, Application of ' Rabit ' Burden Distribution Modelto
BHP Blast Furnaces, IRONMAKING CONFERENCE PROCEEDINGS, USA, 1988, P289~296." in carry
Supplied it is a kind of calculate the algorithm of bed of material slump using bulk cargo layer stability of slope theory, this method only sees Japanese height for many years
Stove, in other countries it is difficult to promote, tracing it to its cause has at following 3 points：On the one hand it needs to be determined that furnace charge is rested in peace in calculating process
Angle, parameters of formula is determined, these parameters are all based on measured value determination, without actual measurement, it is difficult to accurate determination；It is another
Individual aspect can calculate the furnace charge slump amount of free charge level with the theory, but be a closure, restrictive space inside blast furnace,
It is a kind of restrictive slump when furnace charge is hit, slope stability is theoretical with being not appropriate for here；Another aspect is this
Method is a kind of theoretical calculation after all, and how actual state needs for carrying out actual verification.
Being distributed in just because of O/C ratios in blast furnace operating has extremely important effect to air flow method, it is therefore desirable to grasp
Cloth regular of the coke layer under ore impact.
In view of blast furnace is a huge closed reactor, once after operation of blast furnace, unless intermediate repair, or blast furnace are big
Repair, otherwise blast fumance will not stop, blast furnace roof is constantly in a kind of high temperature, high dust, the air-tight state of high pressure, basic nothing
Method realizes the direct measurement of charge level deformation.The experiment of all research furnace charge deformations is all the dress before blast furnace opening in the world at present
Completed during material.Document " firm etc., smelt iron 40 years, and Central China science and engineering is big by new No. 3 BF of WISCO blast furnace opening charging actual measurement, Wuhan Iron and Steel Plant
Learn publishing house, page 371~page 379." in disclose a kind of artificial glass plate mensuration.This method passes through in furnace roof ore layer
Drill rod, which is squeezed into, along radial direction forms support bar, the positioned vertical poly (methyl methacrylate) plate with a scale by support bar, by glass plate
It is fixed between two row's drill rods, coke is then distributed on ore layer, after coke cloth is complete, related personnel enters in stove, determines burnt
Layer of charcoal shape of charge level, records coke layer thickness, related personnel is again gone into stove after the completion of ore, cloth are then distributed into again,
Measurement ore layer shape simultaneously records ore layer thickness, while pushing the change that ore layer observes coke layer aside, judges ore STRENGTH ON COKE
Blastic deformation.Huge poly (methyl methacrylate) plate can stop the rolling of furnace charge, slide, and form serious " wall effect ", and destruction is real
The burden distribution on border；This method wastes time and energy simultaneously, and measurement once needs the time of cost 3~5 days, has a strong impact on manufacturing schedule；
Also, with the maximization of blast furnace, current high furnace volume can typically exceed 4000m3, such huge furnace charge of blast furnace
Charge weight can be more than 200 tons, and furnace charge ulking thickness is more than 1 meter, and such substantial amounts of furnace charge has huge impact kinetic energy, for 3
For~5 meters of high poly (methyl methacrylate) plates, it is difficult to resist this long-time, sharp blow, 3 are realized according to poly (methyl methacrylate) plate~
The charge level deformation measurement of 5 batch of materials is obviously unrealistic.
