I Introduction
Metallum products sunt magni momenti pars metallurgical industria, sed in patriam, in industria est infirma link, mechanica et electrica apparatu est obsoleta, impedit et progressionem in industria. In metal processing, a direct drawing machine is common, in the past a DC generator-motor unit (F-D system) was achieved, but with the progress of process technology and the popularity of frequency converters, frequency conversion control began to be widely used in direct drawing machine, And PLC can be used to achieve the drawing variety setting, operation automation, production process control, real-time closed-loop control, automatic meter counting, and other functions.
