Description
Technical field
This application involves intelligent control methods and dress that detection of fuel technical field more particularly to a kind of sintering fuel are broken
It sets.
Background technique
In sintering production process, solid fuel is generallyd use as sintering fuel, such as coke powder and coal dust.It is produced firing
When product, sintering fuel is covered with entire sintering equipment, such as tunnel oven.And tunnel oven includes preheating zone, combustion zone and cooling zone, often
The sintering temperature of one sintering belt is different, needs by the sintering that same amount and different grain size do not form of different sinter beds arrangement
Fuel controls corresponding temperature.In order to reach best sintering effect, preheating zone, combustion zone and cooling zone width and the bed of material
Thickness need to keep certain proportionate relationship, if the ratio changes, not only result in the decline of sintering quality, also will cause
The consumption of sintering fuel.
Due to the ratio highest that the consumption of sintering fuel occupies in the total energy consumption of sintering process, about 75%~80%,
Therefore, in order to reduce the energy consumption of sintering process, need to reduce the consumption of sintering fuel.However, the fuel pellet of sintering fuel is spent
It is big or too small, it will all increase the dosage of sintering fuel, increase the energy consumption of sintering fuel, sintering quality is caused to degenerate.Not only such as
This, is if in each sintering belt of sintering process, sintering fuel changes with dosage, granularmetric composition and ignition quality,
It will have a direct impact on the temperature and heat distribution, the thickness of combustion zone and the gas permeability of the bed of material, sintering atmosphere, sintering of sinter bed
The various aspects such as quality finally can all cause the consumption of sintering fuel.And when the type of sintering fuel and with dosage it is fixed when, fuel
The size of granularity just becomes the most important factor for influencing sintering process fuel combustion and heat transfer, that is, influences sintering quality and make
At the most important factor of fuel consumption.
For example, combustion zone will be caused to broaden when fuel pellet spends thick (> 3mm), bed permeability is deteriorated；Sintering fuel
Being unevenly distributed in the bed of material, superfuses around bulky grain, and the place remote from bulky grain then cannot be sufficiently sintered；The collection in cloth
In in material layer lower part, the phenomenon that being also easy to produce segregation, cause bed of material top fuel shortage, lower fuel superfluous.And bed of material top is fired
Material is insufficient easily to make sinter short texture, intensity difference；Lower fuel surplus makes sintering belt in sintering process broaden, bed permeability
It is deteriorated, sinter is caused to superfuse, FeO content increases, and reproducibility reduces, and increases blast furnace process coke ratio；It also will cause a part of combustion
Material is unable to full combustion, to ring cold machine on after form double sintering, finished product mine cannot be fully cooled, and burn the severe shadow such as belt
It rings.As fuel granularity meticulous (< 0.5mm), the heat relative distribution for generation of burning in sintering process is unfavorable for improving fuel
The energy consumption of utilization rate, sintering fuel increases, and combustion zone narrows, it cannot be guaranteed that generating the time required for liquid phase in product, causes
Sinter strength is poor, low output, and the rate of return mine is high；Small grain size fuel can hinder air motion in the bed of material, and it is saturating to reduce sinter bed
Gas, and be possible to be entrained by the flow of air.Therefore, generally believe that fuel granularity will reduce fuel granularity<0.5mm, fuel granularity>
The content of two grades of 3mm improves the ratio of 0.5mm-3mm grade.
For this reason, it may be necessary to meet above-mentioned requirements using fuel crushing technology controlling and process fuel granularity.Fuel crushing technique is more universal
Mode be sintering fuel to be squeezed and is broken to 20mm hereinafter, then breaking fuel using four-roller crusher using double-roll crusher
It is broken to 3mm or less.Wherein, the working principle of four-roller crusher is the height generated using high-strength wear-resistant alloy roller relative rotation
Extruding force is crushed fuel, and fuel is brought into the working chamber of roller by the frictional force of roller surfaces, and fuel enters upper two roller
After crusher chamber, by the extruding and shearing force of upper two rollers relative rotation, fuel is squeezed and nibbles mill for the first time, i.e., it is rough and torn
Afterwards, lower two roller that the fuel that granularity is 5-8mm is again introduced into relative rotation immediately is obtained, carries out two using the extruding force of lower two roller
It is secondary to squeeze and nibble mill, i.e. thin broken, it is broken into the discharge of fuel granularity < 3mm fuel.
But the gap between gap in four-roller crusher between upper two roller and lower two rollers need using hydraulic system into
Row is adjusted, and this adjusting method can only control the approximate range of fuel granularity, can not accurately adjust fuel granularity.And in order to subtract
The energy consumption and raising sintering quality of few sintering fuel, need the sintering fuel of each granularity to meet certain ratio, only with liquid
The method that pressure system adjusts gap between breaker roll, can not accurately obtain optimal sintering fuel granularmetric composition.As it can be seen that how
The sintering fuel granularmetric composition accurately controlled in each granularity level becomes this field urgent problem to be solved.

The ratio of one grade fuel is simultaneously unaware of.The fuel ratio for learning specific each grade, can accurately judge currently to be sintered
Whether the granularmetric composition of fuel is reasonable, if unreasonable, can adjust fuel crushing according to the granularmetric composition of current sintering fuel
The upper two roller gap and lower two roller gap of machine 1b, to change the granularmetric composition of sintering fuel.
Specifically, in the present embodiment, current time corresponding sintering fuel granularmetric composition ratio is determined as steps described below:
S121, the grade for obtaining screened device be after tetra- layers of sieve of 0.5mm, 1mm, 3mm, 5mm sieve, fuel granularity <

The weight w of material granularity corresponding sintering fuel between 1mm~3mm3, fuel granularity corresponding sintering combustion between 3mm~5mm
The weight w of material4, and, the weight w of the corresponding sintering fuel of fuel granularity > 5mm5；
Sintering fuel granularmetric composition ratio indicates that therefore, it is necessary to first determine the corresponding sintering combustion of each grade with weight ratio
The weight of material.For this purpose, in this case, it is respectively tetra- layers of 0.5mm, 1mm, 3mm, 5mm sieve that screening plant, which need to configure grade,.Benefit
Do not sift out granularity in < 0.5mm with above-mentioned four layers screening, between 0.5mm~1mm, between 1mm~3mm, 3mm~5mm it
Between, and the sintering fuel of > 5mm, the weight of the corresponding sintering fuel of each granularity is then weighed respectively.
It should be noted that the screening plant in such situation can be with the screening plant of setting 3mm grade sieve above-mentioned
The screening plant of difference, aforementioned setting 3mm grade sieve is arranged in broken process, is convenient for the rough screening of first time；And
The screening plant that four layers of sieve is arranged in this situation can be the device in the screening process in granularmetric composition intelligent analysis module 6,
For careful screening, to screen out granularity in < 0.5mm, between 0.5mm~1mm, between 1mm~3mm, in 3mm~5mm

The sintering fuel composition ratio W5 answered；
W1=w1/W0× 100%, W2=w2/W0× 100%, W3=w3/W0× 100%, W4=w4/W0× 100%, W5=
w5/W0× 100%；In formula, W0The total weight of current sintering fuel.
After weighing the weight of the corresponding sintering fuel of each grade respectively, the total weight W of current sintering fuel0It can also
It learns immediately, the weight summation of the corresponding sintering fuel of as all grades.Utilize the weight of the corresponding sintering fuel of each grade
The ratio of amount and total weight, can calculate each grade corresponding sintering fuel composition ratio W1, W2, W3, W4, W5.
In order to avoid error occurs in measurement, so that adjusting the upper of fuel crushing machine 1b according to sintering fuel granularmetric composition ratio
