Embodiment Construction

[0074] see figure 1 , figure 1 A schematic flow chart of a batching flow regulating method for sintering batching provided in the embodiment of the present application, as shown in figure 1 As shown, the batching flow regulating method of the sintered batching comprises the following steps:

[0075] S110: Collect the actual batching flow of each silo in the multiple silos in real time.

[0076] The sintering ingredients in the examples of this application mostly refer to the fuel and flux materials required for sintering, which are characterized by low specific gravity, small proportion, loose materials, and prone to accidents such as bunkers or spray bins. For this type of sintering ingredients, this In the application embodiment, multiple silos need to be equipped, such as two online main silos and one spare silo. In actual use, two online main silos can be kept running, and the standby silo outputs ingredients when the online main silo is insufficient.

Abstract

The invention discloses a batching flow regulation method and system for sintering burdening. Specifically, the method includes: acquiring the actual batching flow of each one of a plurality of stock bins in real time; calculating the actual ratio fluctuation of the sintering burdening according to the actual batching flow and the preset batching flow of each stock bin; calculating a revised batching flow of the sintering burdening according to the actual ratio fluctuation and the preset batching flow; judging whether the actual total batching flow of the sintering burdening is abnormal according to the actual ratio fluctuation and the revised batching flow; and if the actual total batching flow is abnormal, adjusting a feed port aperture and / or feeding rate of a corresponding stock bin according to the relationship of the revised batching flow with the feed port aperture and the feeding rate respectively. The technical scheme adopted by the invention can timely and accurately stabilize the actual ratio fluctuation.

Description

technical field [0001] The present application relates to the technical field of sintering ingredients, in particular to a method and system for adjusting the flow rate of sintering ingredients. Background technique [0002] At present, iron and steel enterprises often use belt-type draft sintering machines to produce sintering ore. Specifically, the sintering batching is carried out first, that is, by mixing the iron-containing ore powder into an appropriate amount of fuel and solvent, then adding a certain proportion of water, and finally making the material undergo a series of physical and chemical changes after mixing and pelletizing, so that the ore The powder particles stick together into lumps. Among them, sintering batching is an important step in sinter production. [0003] Commonly used sintering batching methods include: volumetric batching method, weight batching method and mass batching method; among them, the weight batching method has higher accuracy and les...
