Abstract: In this paper, the development steps, overall structure and basic functions for the IDSS of operational optimization of copper converter are introduced. The system is of self-study and self-adaption characteristics. It is applied to copper converter and every production quota is obviously improved under the guidance of IDSS after three month characteristics runningtest. The copper productivity is improved by 6 percent, the weight of cold input is increased by 8 percent and the average converter life span is improved from 213 to 235. The economic effect reaches 26.4 million RMB produced by the increased productivity of coarse copper.
