Digital management system for non-ferrous metal metallurgy

The invention relates to a digital management system for non-ferrous metal metallurgy. The average current value I0 of the current day is read from a silicon rectifying device by a current efficiency calculating module of the silicon rectifying device, the actual daily storing output J1 is loaded, and seven groups of data are calculated by combining the data of other modules and are transmitted to a production data summarizing module. The calculation results are summarized to a server by a data base control, and the query is convenient. A powerful reference condition is provided for the investment orientation of a decision maker.
