Description

A kind of secondary Automatic Burden Control System of the sintering for realizing production cost observing and controlling
Technical field
The present invention relates to a kind of fine ore processing system in Ferrous Metallurgy, especially one kind realize production cost observing and controlling The secondary Automatic Burden Control System of sintering.
Background technology
In the technological process of SINTERING PRODUCTION, allocate appropriate fuel and solvent into powdery iron-containing raw material first and make burning The food ingredient of knot raw material is uniform;Secondly also include adding the suitable water yield, it is good to obtain granularmetric composition so as to be easy to pelletizing Sinter mixture, i.e., add appropriate water blended and pelletizing in batches;It is finally sintering work, this is SINTERING PRODUCTION Key link, it mainly includes the master operations such as cloth, igniting, sintering, i.e., on agglomerating plant, make material that a series of things occur Physicochemical changes, and mineral powder granular is cohered in bulk.
There is the unfavorable factors such as production capacity serious surplus, economic slowdown, most enterprises operation in domestic steel industry in recent years It is difficult, enter the sintering deposit such as factory's Iron Ore Powder raw materials for production and keep low stock, the relatively inexpensive economic ore deposit usage amount of price to increase, raw material enters Factory's little, kind of batch is miscellaneous, Change of chemical component is big, substantially increases Iron Ore Matching in Sintering work difficulty.Current many sintering plants are still The mode that artificial burdening calculation determines proportioning raw materials is carried out, its defect is that the simple extensive, degree of accuracy of burdening calculation is low, becomes material operation Quality is strong to the practical work experience dependency of workman, and sintering deposit Chemical bath deposition result draws often delayed dispensing operation Several hours, cause sintered material ratio amendment seriously delayed.Particularly work as used iron-bearing material up to ten several or even numbers Ten kinds, its unit price it is different when, to preferably go out from the Ore that these species are various, price is different and can either meet burning The knot prescription such as ore deposit composition, can make again Iron Ore Matching in Sintering production cost it is optimum with ore deposit scheme, only according to ore deposit experience and simple Calculating can not be solved very well.Although some sintering advanced production factories apply and realize according to the sintering deposit chemical analysis of measuring and calculating Automatic blending, the more suitable proportioning of various raw materials for going out to participate in dispensing according to burdening calculation calculation using models, but shortage have in time The SINTERING PRODUCTION cost accounting of effect, control device, it is impossible to when realizing sintered material, calculate production cost timely and effective pipe in advance Control general expenses.
In today that steel industry slight diarrhea is even lost, for the needs of Production&Operations Management careful calculation and strict budgeting, no matter for Production cost considers that being also in order at iron ore deposit supply occurs all should in the face of the multifarious consideration of iron-bearing material during shortage Constitute from iron ore sintering mine production cost and start with, set up the sintering deposit raw materials for production composition such as Iron Ore Powder(Quality), price and production The relation of corresponding amount between processing charges composition etc., using equal quality sintering deposit production cost height per ton as sintered material pipe The final judging basis of reason, operation quality.
