Technical problem insufficient, gas utilization rate is not high, the present invention provides a kind of Burden distribution method of blast furnace and device, the method packets
It includes: determining the batch weight of each furnace charge, the furnace charge includes: coke and ore；According to preset cloth sequence and each furnace
Expect that each furnace charge is successively distributed into blast furnace by corresponding burden distribution matrix；Wherein, the preset cloth sequence, which is protected, includes:
Bulk coke, small sinter, big granularity sinter+egg coke；The granularity of the bulk coke is greater than 25mm, described small
The granularity of block coke is 12~25mm, and the granularity of the big granularity sinter is greater than 11mm, the granularity of the small sinter
For 4~11mm.
Technical solution of the present invention is described in further detail below by drawings and the specific embodiments.
Embodiment one
The present embodiment provides a kind of Burden distribution method of blast furnace, as shown in Figure 1, which comprises
S110, determines the batch weight of each furnace charge, and the furnace charge includes: coke and ore；
Here, coke includes: egg coke and bulk coke；Ore include: big granularity sinter, small sinter,
Pellet and lump ore etc..Wherein, the granularity of bulk coke is greater than 25mm, and the granularity of egg coke is 12~25mm, and big granularity is burnt
The granularity for tying mine is greater than 11mm, and the granularity of small sinter is 4~11mm.
Because the blast furnace of different size has different production requirements, it is therefore desirable to furnace charge and batch weight be also different.This reality
It applies in example, is the batch weight (coke (per) charge) according to the dischargeable capacity coke of blast furnace, such as not low in the thickness of blast furnace throat position coke (per) charge
In 0.5m, in blast furnace soft melt zone position, the thickness of coke (per) charge is not less than 0.2m.
After coke (per) charge determines, in smelting process, real-time monitoring furnace temperature and gas utilization rate, and according to furnace temperature, coal gas
Utilization rate determines mine batch (batch weight of ore).It here, is true according to the mapping table between furnace temperature, gas utilization rate and mine batch
Determine mine batch, which determined according to historical experience value.
Dischargeable capacity with certain blast furnace is 3200m3For, coke batch weight are as follows: 19 tons, comprising: 16.5 tons of bulk coke, small
2.5 tons of block coke.
The batch weight of ore is 90 tons, comprising: big 45 tons of granularity sinter, 17 tons of small sinter, 13.5 tons of pelletizing, block
13.5 tons of mine.
S111, according to preset cloth sequence and the corresponding burden distribution matrix of each furnace charge by each furnace charge successively
It is distributed into blast furnace；Wherein, it includes: bulk coke, small sinter, the sintering of big granularity that the preset cloth sequence, which is protected,
Mine+egg coke；
After determining mine batch and coke (per) charge, according to preset cloth sequence and the corresponding burden distribution matrix of each furnace charge

It includes: bulk coke, small sinter, big granularity sinter+egg coke that preset cloth sequence, which is protected,；First it is distributed into
Bulk coke is distributed into small sinter again, is finally distributed into big granularity sinter.
It is this to be distributed into small sinter to blast furnace prior to big granularity sinter, and small sinter cloth angle position
Increase to the consistent distributing mode in big granularity sinter cloth angle position, in blast furnace radial distribution, small grain size pellet is not
The contact conditions of ore and coke are improved it is also possible that coke is penetrated into small sinter part positioned at blast furnace edge,
Enable preferably to contact with ore by the Gas Flow of coke layer, the reduction reaction of ore occurs, so that gas utilization rate is improved,
Reduce blast furnace fuel ratio；And after coke layer is penetrated into small sinter part, the thickness of ore layer can be made to be thinned, be conducive to change
Kind soft melt zone gas permeability (in soft melt zone, because ore drain into it is soft melt state, porosity is greatly reduced, gas permeability significantly under
Drop becomes the main resistance of Gas Flow rising, and coke layer is still solid state at this time, is the main logical of Gas Flow rising
Road, referred to as " burnt window ".Therefore the gas permeability that ore layer thickness is conducive to improve soft melt zone is reduced).
Specifically, when being distributed into bulk coke, corresponding burden distribution matrix is C987651 332223.I.e. in No. 9 Jiao Wei
3 circle bulk coke are distributed into, are distributed into 3 circle bulk coke in No. 8 Jiao Wei, 2 circle bulk coke are distributed into No. 7 Jiao Wei, at No. 6
Angle position is distributed into 2 circle bulk coke, is distributed into 2 circle bulk coke in No. 5 Jiao Wei, is distributed into 3 circle bulk coke in No. 1 Jiao Wei.
Then small sinter is distributed into furnace according to small sinter corresponding burden distribution matrix, here, for height
The distribution proportion of radial various raw material varieties is balanced in furnace furnace, and the basicity of slag that each region is formed is consistent, avoids in blast furnace
Furnace inward flange region because basicity of slag it is excessively high caused by mobility decline, lead to the phenomenon of furnace wall knot thickness, granule in the present embodiment
The cloth angle position for spending sinter is consistent with the cloth angle position of big granularity sinter, the cloth angle of small sinter in the present embodiment
Position and the cloth angle position of big granularity sinter are all 5.
The corresponding burden distribution matrix of small sinter is OS98765 11111, i.e., 1 circle small grain size is distributed into No. 9 Jiao Wei
Sinter, is distributed into 1 circle small sinter in No. 8 Jiao Wei, 1 circle small sinter is distributed into No. 7 Jiao Wei, at No. 6
Angle position is distributed into 1 circle small sinter, is distributed into 1 circle small sinter in No. 5 Jiao Wei.
Finally according to the corresponding burden distribution matrix of big granularity sinter by big granularity sinter and the nut coke cloth of recycling
Enter in blast furnace.
The corresponding burden distribution matrix of granularity sinter is O greatlyL98765 33322, i.e., the big granularity of 3 circles is distributed into No. 9 Jiao Wei
Sinter+pellet+lump ore+egg coke is distributed into the big granularity sinter+pellet+lump ore+nut coke of 3 circles in No. 8 Jiao Wei
Charcoal is distributed into the big granularity sinter+pellet+lump ore+egg coke of 3 circles in No. 7 Jiao Wei, is distributed into the big grain of 2 circles in No. 6 Jiao Wei
Sinter+pellet+lump ore+egg coke is spent, is distributed into the big granularity sinter+pellet+lump ore+fritter of 2 circles in No. 5 Jiao Wei
