RH furnace has been widely used in recent years.It is urgent for iron and steel enterprises to realize intelligent continuous produc-tion without intervention.It adopts a novel level-1 architecture that level-1 system realizes the integration of all functions of the level-2 sys-tem.The control system of the original design can not realize automatic heating of the oxygen lance.Has been using decarburization mode,manually add aluminum balls to heat up,control of aluminum-oxygen ratio is uncontrollable.After the vacuum system is aged,the steam valve,water valve,communication valve and relief valve shall be operated manually one by one.Frequent misoperation,resulting in equipment dam-age.The need for intelligent upgrading and transformation is urgent.Intelligent steelmaking technology incorporates a switching-free human-ma-chine interface,artificial neural network temperature prediction model,oxygen Lance control model based on Dahlin algorithm,carbon monoxide decarburization model of hot water well,virtual silometer and so on.These new technologies have completely independent intellectual property rights and Successfully applied in 5 # RH furnace of Benxi Steel Plate Co.Ltd..The invention realizes the continuous and non-intervention automatic production of the integral casting times of the ultra-low carbon steel grade and And has good popularization prospect.
