Application of intelligent crane control system in bottom filtration process of blast furnace
According to the analysis of the functional requirements of blast furnace bottom filtration process(normally called OCP)and the structure of bridge grab-crane,the intelligent control system of grab crane was proposed.The system adopts the technology of automatic positioning of crane and grab bucket,frequency conversion speed control,anti-sway grab,wireless network communication,video surveillance,knowledge learning algorithm,etc.,to achieve the intelligent control of the grab crane.The system divides the filter tank into grid according to the process requirements,and adopts an efficient slag grabbing strategy to automatically control the grab bucket to complete the grabbing and slag discharge operations.The practical application results of the intelligent control system of grab crane in the bottom filtration process of many blast furnaces show that the operation rate of the system is more than 99％,which is 32.5％higher than the efficiency of manual slag grabbing,reducing staff 66.7％,and the maintenance cycle is doubled.
