Embodiment one:
Fig. 1 is solid-fuelled control method exemplary process diagram in the embodiment of the present invention one sintering process.Present embodiments provide solid-fuelled control method in a kind of sintering process, described method can comprise:
S11: the content value obtaining FeO in finished product agglomerate.
The FeO content of agglomerate is the important indicator of sinter quality, and the content value of FeO can be obtained by instant chemical examination agglomerate data, also can be adopt result nearest in trace routine.
S12: the relation judging the content value of FeO and the FeO codomain interval of setting.
The FeO index of sintering plant to sintering quality qualified product has certain claimed range, is referred to as codomain interval.FeO content controls in suitable interval, can obtain Well-recovered and that intensity is high agglomerate, can also reduce and return mine, improve Sintering Yield.The content value being in the FeO between the maximum in codomain interval and low value represents and meets the requirement of industrial production to product.The content of sintering mine FeO depends on solid-fuelled mixed carbon comtent substantially, both correlations, so can with the content of FeO for the solid-fuelled proportioning of feedback adjustment.
S13: control solid fuel proportioning and reduce.
If the content value of the FeO obtained is greater than the maximum in FeO codomain interval, represent the too high levels of FeO.FeO Content in Sinter is too high, and the reductibility of smelting is deteriorated, unfavorable to blast furnace iron increasing and coke saving, and agglomerate solid burnup also can be caused high simultaneously, is unfavorable for reducing production cost.So adjust by sending the control command reducing solid fuel proportioning.
S14: monitoring solid fuel proportioning.
If the content value of FeO is more than or equal to the Schwellenwert in FeO codomain interval and is less than or equal to the maximum in FeO codomain interval, represent that FeO content is in normal codomain interval.But because sinter quality is also by the impact of other parameters, such as, sintered ore rotary drum strength (ISO) is the reflection of agglomerate physical strength, so the instruction of monitoring solid fuel proportioning at this moment should be sent, maintenance system parameter is constant, perform refresh operation, detect other parameters and according to its occurrence micro-tensioning system simultaneously.
S15: control solid fuel proportioning and improve.
If the content value of FeO is less than the Schwellenwert in FeO codomain interval, represent that the content of FeO is too low.FeO Content in Sinter is too low, then shortage of heat needed for sintering reaction, and sinter strength declines, and cause returning mine many, yield rate is low.So adjust by sending the control command improving solid fuel proportioning.
Adjustment step-length can be calculated according to practical situation, once adjust complete, but now may be comparatively large due to adjustment step-length, cause system change comparatively large, impact can be brought to system stability.So on the basis of embodiment one, one of them preferred embodiment is, reducing the steering order of solid fuel proportioning and the steering order of described raising solid fuel proportioning described in embodiment one, is the instruction of the predetermined solid fuel change step of execution one.

S133: control solid fuel proportioning and reduce according to the first decline step-length.
If barrate strength value is greater than the maximum in barrate strength codomain interval, represent that barrate strength is too high.When the FeO content of agglomerate and barrate strength all higher, reduce solid fuel proportioning according to the first decline step-length.First decline step-length is that drop-out value is maximum.
S134: control solid fuel proportioning and reduce according to the second decline step-length.
If barrate strength value is less than the Schwellenwert in barrate strength codomain interval, represent that barrate strength value is on the low side.Now the FeO content of agglomerate is higher, but when barrate strength is on the low side, reduces solid fuel proportioning according to the second decline step-length.Second decline step-length is less than the value of the first decline step-length.
S135: control solid fuel proportioning and reduce according to the 3rd decline step-length.
If barrate strength value is more than or equal to the Schwellenwert in barrate strength codomain interval and is less than or equal to the maximum in barrate strength codomain interval, represent that barrate strength value is normal.Now the FeO content of agglomerate is higher, but in the normal situation of barrate strength, reduces solid fuel proportioning according to the 3rd decline step-length.3rd decline step-length is less than the value of the second decline step-length.
