Abstract

The invention provides a control system and a control method for a pelletizer. The system comprises a pelletizer, a water supply device, a feeding belt weigher, a rotating speed controller, an inclination angle controller, a water controller, a material controller and a central processing unit; the central processing unit is configured to execute the following steps that according to the rotating speed of a pelletizer, the inclination angle of a pelletizing disc of the pelletizer, the feeding amount, the water feeding amount, the variety and proportion of all components in a mixture, the proportion of a binder in the mixture and the original moisture rate of the mixture, the qualified rate of green pellets is predicted, and predicted values of the qualified rate of green pellets in multiple prediction periods are obtained; the rotating speed of the pelletizer, the inclination angle of a pelletizing disc of the pelletizer, the feeding amount and the water feeding amount are optimized by adopting a rolling optimization model in combination with the predicted value of the qualified rate of the green pellets and a preset target value of the qualified rate of the green pellets; and therefore, the rotating speed of the balling machine in the balling machine, the inclination angle of the balling disc of the balling machine, the feeding amount provided for the balling machine and the water feeding amount provided for the balling machine are controlled in real time.

Description

technical field [0001] The present application relates to the technical field of iron and steel smelting, in particular to a control system and control method for a pelletizing machine. Background technique [0002] In the iron and steel industry, pellet manufacturing is currently the most commonly used iron ore extraction technology. Among them, the pelletizing process is an important process of the iron ore pellet production line, and the stability and improvement of the production and quality of green pellets mainly depend on the pelletizing process. As the core equipment in the pelletizing process, the pelletizing machine mainly includes a disc pelletizing machine and a cylinder pelletizing machine. A cylinder pelletizing machine is generally used in a large-scale high-volume production line. However, due to the current small and medium-scale pelletizing production line Dominant, so disc pelletizers are more common. [0003] When the pelletizing machine is working, the...
