Copper converter converting control system

The invention discloses a copper converter converting control system which comprises a slag forming end point detection unit and a copper forming end point detection unit, wherein the slag forming end point detection unit is used for online collecting characteristic spectrum emission intensity signals of PbO and PbS of the melt in a copper converter in the slag forming period; the copper forming end point detection unit is used for online collecting gas concentration signals of SO2 in flue gas in a copper converter gas duct A in the copper smelting period; a data processing unit is used for analyzing and processing the signals collected by the slag forming end point detection unit and the copper forming end point detection unit to judge whether the converting reaches the slag forming end point and the copper forming end point, and performs regulation and control to determine whether the blowing out is performed. The control system can accurately judge the slag forming end point and the copper forming end point, so that the phenomena including over-blowing, under blowing and the like can be avoided, the safety production of copper converter converting is ensured, and the efficiency of copper smelting is improved.
