Description
Technical field
The present invention relates to a kind of steel making equipments, relate in particular to a kind of blast furnace, more particularly to a kind of high furnace charge
Layer measurement method and device.
Background technique
When blast furnace ironmaking, furnace charge is packed into furnace by " the no bell " of furnace roof, by means of the hot wind of bottom house blasted, is led to
It crosses combustion of coke and generates heat and carbon monoxide, on the one hand heat furnace charge, furnace charge is on the other hand restored, 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.Pass through tune in blast furnace operating
Whole cloth doses, cloth sequence, the control measures 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 furnace, distribution of the heat in furnace is on the one hand controlled, on the one hand two control different parts in furnace
Learn reaction speed, and then the functions such as optimization, troubleshooting for realizing blast fumance.
Two kinds of furnace charges generally are packed into from furnace roof when cloth, coke and ore, coke are individually packed into as fuel, and ore is general
Including sinter, pellet, lump ore, it is fitted into blast furnace together after mixing in batch can.Current nearly all large blast furnace is all
It is that furnace charge is distributed into furnace using no clock apparatus for distributing, realizes the loading of furnace charge, this equipment is by chute in different angle positions
Different circle numbers are rotated gradually furnace charge is distributed into furnace to realize.
After furnace charge is packed into furnace, ore and coke will form certain stratiform bed of material, and be formed along blast furnace radial direction
Certain thickness generally will form the shape of charge level of marginal belt platform.Combustion of coke generates heat and carbon monoxide in burner hearth in furnace
Interior formation air-flow, because of the difference of cloth type and cloth doses, coke and ore are different along radial direction formation thickness in furnace roof
Distribution, and air-flow flowing is influenced 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 represents it to coal gas
The different resistances of stream.The thickness ratio of ore and coke layer is generally used in production, i.e. O/C as blast furnace roof air-flow than adjusting
A kind of judgment criteria.
In blast furnace operating, the distribution of O/C ratio directly determines blast furnace air flow method, this parameter is to blast furnace operating to pass
It is important.But O/C ratio is difficult to accurately calculate out in practical blast furnace operating, mainly the charge level shape due to being formed after the complete coke of cloth
Shape, during subsequent cloth mine, because ore impact force is big, when falling on the coke layer being made of bulk cargo, coke layer can collapse
It falling, this slump can destroy the coke shape of charge level formed before the subsequent mine of cloth, so that true O/C ratio distribution cannot be obtained,
Key problem is exactly the slump amount for dully knowing furnace charge, slump position, coke and the situation of ore mixing.Document " Kim L
Hochings, John M Burgess, Application of ' Rabit ' Burden Distribution Modelto
BHP Blast Furnaces, IRONMAKING CONFERENCE PROCEEDINGS, USA, 1988, P289~296." in mention
A kind of algorithm that bed of material slump is calculated using bulk cargo layer stability of slope theory is supplied, this method only sees Japanese height for many years
Furnace is difficult to promote in other countries, traces it to its cause following 3 points: on the one hand it needs to be determined that furnace charge is rested in peace in calculating process
Angle determines parameters of formula, these parameters are all based on what measured value determined, without actual measurement, is difficult accurate determination；It is another
A aspect theory can calculate the furnace charge slump amount of free charge level, but be a closure, restrictive space inside blast furnace,
It is a kind of restrictive slump when furnace charge is hit, slope stability theory with being not appropriate for here；Another aspect is this
Method is a kind of theoretical calculation after all, and how actual state still needs to carry out practical verification.
Being distributed in blast furnace operating just because of O/C ratio has extremely important effect to air flow method, it is therefore desirable to grasp
Cloth regular of the coke layer under ore impact.
It is a huge closed reactor in view of blast furnace, after operation of blast furnace, unless intermediate repair or blast furnace are big
It repairs, otherwise blast fumance will not stop, and blast furnace roof is constantly in a kind of high temperature, air-tight state dusty, high pressure, basic nothing
Method realizes the direct measurement of charge level deformation.The experiment that all research furnace charges deform in the world at present is all the dress before blast furnace opening
It is 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
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 rod, the positioned vertical poly (methyl methacrylate) plate with a scale by support rod, by glass plate
It is fixed between two rows of drill rods, coke is then distributed on ore layer, after coke cloth is complete, related personnel enters in furnace, and measurement is burnt
Layer of charcoal shape of charge level records coke layer thickness, is then distributed into ore again, and related personnel again goes into furnace after the completion of cloth,
Measurement ore layer shape simultaneously records ore layer thickness, while pushing the variation of ore layer observation coke layer aside, judges ore STRENGTH ON COKE
Blastic deformation.Huge poly (methyl methacrylate) plate can stop the rolling of furnace charge, slide, and be formed serious " wall effect ", destroy real
The burden distribution on border；This method is time-consuming and laborious simultaneously, and measurement need to once spend 3~5 days time, seriously affects manufacturing schedule；
Also, with the enlargement of blast furnace, current high furnace volume generally can be more than 4000m3, furnace charge of such huge blast furnace
Charge weight can be more than 200 tons, and furnace charge ulking thickness is more than 1 meter, and so a large amount 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, realize 3 according to poly (methyl methacrylate) plate~
The charge level deformation measurement of 5 batch of materials is obviously unrealistic.
