Description
Technical field
The present invention relates to sintering technology field more particularly to a kind of sintering process monitoring device and sintering machines.
Background technique
In modern blast furnace iron-smelting process process, it is sintered and provides the core link of qualified feed stock for blast furnace as to blast furnace, account for
According to and its consequence.Its mechanism is that various powdery iron-containing raw materials are incorporated a certain number of solvents and fuel, and mixing is equal
Then even granulation is put into ignition sintering on agglomerating plant.The work of high temperature and a series of physical chemical reaction is generated in fuel combustion
With under, the generation of part lyotrope matter softens, melts, generating a certain number of liquid phases and soak other unfused in mixture
Ore particles, after cooling, liquid phase bonds mineral powder granular blocking, and gained block is sinter.

9 include the sintering stage positioned at 2 top of bellows, and the starting point of sintering stage corresponds to the head of sintering machine, the final position pair of sintering stage
Answer the tail of sintering machine.Trolley 1 completes the loading of sintering feed 5 in the starting point of sintering device handpiece position i.e. sintering stage, and
And trolley 1 completes the unloading of sintering feed 5 in rear of sintering machine position i.e. the final position of sintering stage.
Sintering of the bellows 2 to being loaded in trolley 1 while trolley 1 is moved along sintering stage, below sintering stage
Material 5 carries out exhausting, to complete sintering process.The negative pressure of 2 exhausting of bellows mostlys come from main exhauster, in production, main pumping
Blower generates strong negative pressure and negative pressure is finally passed to bellows 2 by large flue 4 and wind box branch pipe 3.
From Fig. 2 and Fig. 3 it is found that the sintering feed 5 being loaded in trolley 1 forms combustion zone after the igniting of ignition furnace 7
6, while trolley 1 is moved from sintering machine head to tail, combustion zone 6 is influenced to transport to 1 bottom of trolley by 2 negative pressure of bellows
It is dynamic.When most reasonable operating condition is that trolley 1 moves to tail from sintering machine head end, combustion zone 6 just from 5 upper layer motion of sintering feed to
Bottom, sintering machine entirety power consumption values are minimum at this time, sinter quality is best.

The throttle opening of each bellows 2 in sintering machine lower part can not be just accurately controlled, thus easily causes main pumping exhausting amount seriously superfluous,
Form serious power consumption waste.Such case can be effectively relieved in main pumping converter technique to a certain extent, but has been the absence of mistake
The accurate monitoring means of journey, relies only on the soft supposition of model, and precision is far from being enough；
Sinter quality is poor: due to that can not move down situation by combustion zone 6 in 5 layers of real-time monitoring sintering feed, also can not just control
The residence time of combustion zone 6 processed each height in 5 layers of sintering feed.It is well known that the drum strength of sinter, reproducibility, low
The parameters such as warm reduction and pulverization ratio are related with the maximum temperature point of arrival and temperature hold-time, if combustion zone can not be controlled effectively
6 residence times, the roasting quality of sinter just can not be precisely controlled, obtained sinter quality is also necessarily affected；
Easily cause chain negative effect: since situation can not be moved down by combustion zone 6 in 5 layers of real-time monitoring sintering feed, sometimes
Time will appear after sinter is discharged on ring cold machine from sintering machine, also the case where continuing sintering process, can seriously affect in this way
The cooling effect of ring cold machine also has negative effect to equipment such as 1 castor item of trolley, blow tank, belts.
