Method and device for controlling feeding in sintering burden process

Abstract

The embodiment of the invention discloses a method and a device for controlling feeding in a sintering burden process. The method comprises the following steps: obtaining the set feeding amount at current moment, and detecting the actual feeding amount at current moment; calculating the sum of the set feeding amount obtained within the latest statistics cycle as the set feeding aggregate value, and calculating the sum of the actual feeding amount detected with the latest statistics cycle as the actual feeding aggregate value; calculating the difference between the set feeding aggregate value and the actual feeding aggregate value as an aggregate deviation value; and correcting the set feeding amount with the aggregate deviation value to obtain the correction value of the set feeding amount, so as to carry out feeding control according to the correction value of the set feeding amount. Through the method disclosed by the embodiment of the invention, the aggregate compensation is achieved at a certain extent; the raw material proportioning deviation caused by aggregate compensation is avoided; and the efficiency of the sintering process and the yield of agglomerate are improved.

Description

technical field [0001] The present application relates to the field of sintered ore, in particular to a method and device for controlling feeding during the sintering batching process. Background technique [0002] In the process of sintering production, sintering ingredients are an important process link. Specifically, sintering batching is a process in which iron raw materials, returned ore, flux, fuel, quicklime, dust and other raw materials are mixed together in a certain proportion according to the quality index requirements of sintered ore and the raw material composition. see figure 1 , Various raw materials are loaded and unloaded to the tape through its silo, and the tape passes through the bottom of each raw material silo in turn under the drive of the belt conveyor, so that the unloading of each raw material silo can be matched together. [0003] In the sintering process, the appropriate ratio of various raw materials can not only increase the output of sintered...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a method and device for controlling the blanking during the sintering batching process, so as to solve the problem of the total actual blanking amount and the total blanking amount in the entire blanking control process before the current moment in the prior art. The total deviation between the set amount of blanking is used to control the actual deviation of raw material ratio caused by the current blanking, so as to improve the efficiency of the sintering process and the output of sintering ore
