Description
Technical field
The present invention relates 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 measuring method and device.
Background technology
During blast furnace ironmaking, furnace charge is loaded in stove, by means of the hot blast for blasting of bottom house by " without the bell " of furnace roof, 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 produce.Simultaneously the smelting process of blast furnace is also being adjusted by cloth and air blast parameter.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, so as to control CO,
CO2、H2Deng the distribution in the stove, on the one hand control distribution of the heat in stove, two on the one hand different parts in control stoves
Response speed is learned, and then realizes the functions such as the optimization of blast fumance, troubleshooting.
Typically load two kinds of furnace charges, coke and Ore from furnace roof during cloth, coke individually loads as fuel, and Ore is general
Including sintering deposit, pellet, lump ore, load together in blast furnace after mixing in batch can.Current nearly all large blast furnace is all
It is to adopt furnace charge to be distributed in stove without clock apparatus for distributing, realizes the loading of furnace charge, this equipment is in different angle positions by chute
Rotate the different number of turns to realize gradually furnace charge is distributed in stove.
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 boundary zone platform.In stove, combustion of coke produces heat and carbon monoxide in burner hearth
Interior formation air-flow, because of cloth species and the difference of cloth doses, it is different that coke forms thickness in furnace roof along radial direction with Ore
Distribution, and air current flow is affected by bed of material granularity and thickness.Ore grain size is little, than great, the thickness of feed layer of formation is big
Where 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 which to coal gas
The different resistances of stream.The general thickness ratio for using Ore and coke layer in production, i.e. O/C is than being used as the adjustment of blast furnace roof air-flow
A kind of judgment criteria.
In blast furnace operating, the distribution of O/C ratios directly determines blast furnace air flow method, and this parameter is to blast furnace operating to pass
It is important.But in actual blast furnace operating, O/C ratios are difficult to accurately calculate and, 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, the coke shape of charge level that this slump is formed before destroying the follow-up ore deposit of cloth, so as to real O/C can not be obtained than distribution, 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
Supply a kind of utilization bulk cargo layer stability of slope theory to calculate the algorithm of bed of material slump, 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, determine parameters of formula, these parameters are all based on measured value determination, do not carry out actual measurement, it is difficult to accurately determine；It is another
The individual 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, theoretical being used in of slope stability is not appropriate for herein；It is this in terms of another
Method is a kind of Theoretical Calculation after all, and how actual state to need for carrying out actual verification.
Is distributed in blast furnace operating in the extremely important effect that have to air flow method just because of O/C ratios, it is therefore desirable to grasped
Cloth regular of the coke layer under Ore impact.
In view of blast furnace is a huge closed reactor, after operation of blast furnace, unless intermediate repair, or blast furnace is 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
Complete during material." Zhang Yi etc., the charging actual measurement of new No. 3 BF of WISCO blast furnace opening, Wuhan Iron and Steel Plant are smelted iron 40 years document, and Central China science and engineering is big
Publishing house, page 371～page 379." in disclose a kind of artificial glass plate measurement method.The method is by furnace roof ore layer
Drill rod is squeezed into along radial direction and defines support bar, the positioned vertical poly (methyl methacrylate) plate with a scale by the support bar, by glass plate
Be fixed between two row's drill rods, then coke be distributed on ore layer, after coke cloth is complete, related personnel is entered in stove, determine burnt
Layer of charcoal shape of charge level, records coke layer thickness, is then distributed into Ore again, and after the completion of cloth, related personnel is again gone in stove,
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, landing, form serious " wall effect ", and destruction is real
The burden distribution on border；The method wastes time and energy simultaneously, and measurement once needs the cost time of 3～5 days, has a strong impact on manufacturing schedule；
Also, with the maximization of blast furnace, high furnace volume can typically exceed 4000m at present3, such huge furnace charge of blast furnace
Charge weight can be more than 200 tons, and more than 1 meter, so substantial amounts of furnace charge has huge impact kinetic energy to furnace charge ulking thickness, 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.
