Slag Drying and Conveying System Based on 32 Single Chip Microcomputer and PLC

Aiming at the core problems of low efficiency, high labor cost and poor stability in the slag baking process of the electric slag furnace workshop, this study was guided by the actual production needs of a large domestic steel plant and successfully developed an intelligent slag baking automation system based on STM32 single-chip microcomputer and Siemens S7-200 SMART PLC. The system realizes the seamless conversion of modbusrtu and profinet protocols through the Wuya iot WTU-PNMD02 gateway, builds a distributed control network of "single-chip microcomputer master control-PLC field control-sensor real-time feedback", and integrates core functions such as fully automatic loading, precise baking, intelligent weighing, efficient transportation and safe unloading. Through hardware selection optimization, software algorithm innovation and mechatronics design, the system realizes the unmanned and intelligent slag handling process, significantly improves the efficiency, precision and safety of metallurgical production, and provides a replicable technical solution for the digital transformation of the traditional metallurgical industry.
