Description
Technical field
The utility model is related to sintering machine technical field, more particularly to a kind of step-by-step type sintering machine double-layer cloth device.
Background technology
The decisive precondition of high-quality sintering deposit production is that in overall mixing process, all raw materials should be equably
Distribution, the highly-breathable of raw material ensure that the thickness of feed layer on sintering machine gradually increases, so as to correspondingly reduce sintering process
Middle fuel consumption.
Bilayer is sintered in the former Soviet Union, Germany and some Japanese factories and used, former Soviet Union Cha Bada-Xi Beiliya Metallurgical Factories
Double-deck sintering is carried out, carbon 3.8% is matched somebody with somebody on upper strata, and carbon 3.2% is matched somebody with somebody by lower floor, as a result reduces coke powder content 8%.Now, various leading indicators are
Most preferably, i.e. the qualification rate of productivity of sintering machine, mechanical strength and sintering deposit is optimal.Certain Japanese factory is saved using double-deck sintering
Burnup 10%, productivity ratio increase by 2%.But, because step-by-step type sintering machine is only provided with a set of grate-layer material cloth on sintering machine head
System and mixture distributor system, conventional sintering machine are divided into sintering device handpiece, rear of sintering machine, sintering zone, cooling zone, are burning
Knot chain-drive section is sequentially provided with grate-layer material distribution device, and mixture distributor device sinters preheating device, ignition furnace and cooling device,
Its sintering process flow is followed successively by grate-layer material cloth, and mixture distributor is preheated, lighted a fire, sintering, cooling etc..Due to bed of material top
Because heat supply is not enough, cooling velocity is fast, causes sintering temperature low, coheres that phasor is few, and sinter strength is low, produces many and returns mine；
And material layer lower part is acted on due to the accumulation of heat of sintering process, sintering temperature is high, and superfusion is produced sometimes, causes the reproducibility of sintering deposit
Difference, sinter bed declines larger.
The content of the invention
This purpose of this utility model be to provide it is a kind of it is simple in construction, easy to operate, sintered compound can be effectively improved
The gas permeability of material, reduces the double-layer cloth device of the step-by-step type sintering machine of production cost.
What this purpose of this utility model was realized in.
According to a kind of double-layer cloth device of step-by-step type sintering machine of the present utility model, including along the operation of sintering pallet
The grate-layer material being made up of shop fixtures feed bin, gate of sector-like shape, swinging funnel and bulkhgead gate that the top in the once sintered area in direction is set
Distribution device and by blending bunker, is arranged on the regulating gate of blending bunker bottom, be arranged on the round roller of regulating gate bottom to
Distribution device of compound of material machine and multi-roller spreader composition, the once sintered preheating above once sintered area
Device and an ignition furnace, it is characterised in that increase compound secondary distributing device successively in the top in double sintering area, secondary
Preheating device and regnition stove are sintered, described secondary distributing device is arranged on the tune of blending bunker bottom by blending bunker
Gate is saved, the round roller batcher and multi-roller spreader for being arranged on regulating gate bottom are constituted.
The roller number of described multi-roller spreader is 5-9.
Described double sintering preheating device sinters preheating device using steam.
Described regnition stove uses oxygen-enriched ignition stove.
The bulkhead inclination angle of described blending bunker is less than 70 °.
The round roller appearance of described round roller batcher is lined with stainless steel plate.
The utility model has the advantage of：Due to the utility model, to increase compound successively in double sintering area secondary
Cloth system, double sintering pre-heating system and secondary oxygen-enriched ignition stove, form double-layer cloth device, it is possible to reduce a cloth thickness
Degree, compound secondary material distributing can effectively supplement it is once sintered during volume contraction space, make above and below the bed of material thickness proportion most
It is good, it is 1：4~2：3；Fuel ratio 1.5：1~1.2：1, sinter strength is effectively improved, quantity of return mines is reduced.
The material layer lower part of bilayer sintering due to can be reduced using the accumulation of heat of sintering process with addition of fuel quantity, therefore both
The total solid burnup of sintering can be reduced can make the uniform quality of sinter bed again.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, according to a kind of double-layer cloth device of step-by-step type sintering machine of the present utility model, including along sintering machine
The top in the once sintered area of traffic direction of chassis set by shop fixtures feed bin 1-1, gate of sector-like shape 1-2, swinging funnel 1-3 and flat
Plate gate 1-4 composition grate-layer material distribution device 1 and by blending bunker 2-1, be arranged on the regulating gate of blending bunker 2-1 bottoms
2-2, is arranged on cloth of compound of round roller batcher 2-3 and multi-roller spreader the 2-4 composition of regulating gate 2-2 bottoms
