Disc pelletizing intelligent production system and control method thereof

Abstract

The invention discloses a disc pelletizing intelligent production system and a control method thereof, and the control system comprises an upper computer control unit, a field control unit, a detection unit, and an electric execution unit. The control system cooperates with the control method, carries out the processing of data and the setting of preset values through the upper computer control unit, and then transmits the data to the field control unit for production control. The detection unit is used for collecting a plurality of practical technological values related with the pelletizing qualified rate in a field disc pelletizing process, and transmitting a detection result to the field control unit for logic criterion in real time. According to the invention, the detection unit serves a data input unit of a production control system, and the electric execution unit serves as a data output unit. The system achieves the adjustment of the production technological parameters of a disc pelletizing device through a programmable logic controller, achieves a purpose of controlling the pelletizing qualified rate in a preset qualified range, and improves the product quality.

Description

Technical field [0001] The invention relates to the technical field of monitoring systems, in particular to an intelligent production control system for disc pelletizing and a control method thereof. Background technique [0002] With the continuous depletion of resources and the continuous rise of international iron ore prices, the quality of raw fuel used in blast furnaces continues to deteriorate. For large blast furnaces, the operation of the blast furnace and the quality of molten iron are closely related to the raw materials, and the raw materials play a very important role in the smooth operation and stability of the blast furnace operation. Pelletizer is the equipment to provide pelletized mineral materials for blast furnace. The qualified rate of pelletizing and the proportion of ore materials will directly affect the production quality of blast furnace. [0003] At present, the production process of the pelletizing section is too dependent on manual operation. The amount...

Problems solved by technology

[0003] At present, the production process of the pelletizing section is too dependent on manual operation. The amount of water added, the amount of material added, the speed of the pelletizing disk, and the inclination of the pelletizing disk are adjusted by the operator based on experience and eyesight. The qualification rate of the green ball diameter, which not only causes production waste but also affects the production efficiency of the sintering section
