Copper matte converter blowing is the process of converting copper matte into crude copper in copper smelting process. The blowing process is divided into copper making period and slag making period. The judgment criteria and methods of each stage are different. The quality of crude copper is related to the accuracy of endpoint judgment. Especially with the increasing complexity of raw material composition, the difficulty of judging and controlling the endpoint of blowing is greatly increased. Based on the current research status of endpoint judgment methods for copper smelting converter blowing at home and abroad, this paper expounded the research progress of four kinds of blowing endpoint judgment methods, such as artificial experience method, instrument measurement method, material balance method and neural network method, and looked forward to the development direction of endpoint judgment methods for copper smelting blowing. With the development of detection instruments, the improvement of blowing air supply and material measurement accuracy, coupled with the improvement of converter blowing automation and the development of artificial intelligence, the end point control of copper matte converter blowing is developing towards automatic and accurate judgment and intelligent control.
