Humidity control method for mixture used in sintering production

Abstract

The invention relates to a method for controlling moisture of a mixture for sintering production, and belongs to the technical field of automatic monitoring and intelligent control of mixture moisture. The method adopts a PLC system and a development tool. The control process comprises data acquisition, signal display, data processing, manual input of information, model operation and adjustment for fuzzy control, control quantity output, model self-adapting, and judgment and correction of manual intelligent mode. The method achieves automatic dynamic control of water adding amount of the sintered mixture to make the mixture moisture meet sintering production demand, displays data such as real-time moisture, water adding amount and the like of the material in the production process, and displays operation mode and the like. The method has the advantages that the method is suitable for control of the water adding amount in a mixing process using various sintering production process raw materials, can design an independent control system or can be realized by using the PLC control system based on automatic control of the production process, is limited little by field conditions, is suitable for new projects and reformed projects, and has low cost.

Description

technical field [0001] The invention belongs to the technical field of automatic monitoring and intelligent control of the moisture content of the mixture, and in particular provides a method for controlling the moisture content of the mixture used for sintering production. Background technique [0002] At present, the sintering plant of Shougang Mining Co., Ltd. adopts the control method of manually watching water, and the water adding method is two-stage water adding, with the primary mixing water adding and the secondary mixing adding water supplemented. The key points of the process operation are: adding water for the first mixing requires sufficient mixing, and adding water for the second mixing requires a small amount of supplementary to strengthen granulation. The feeding end of the primary and secondary mixers is designed with a storage bin, and the feeding method is the feeding of the round roller feeder, and the round roller is equipped with an electric valve and a...
