Document Type and Number:
WIPO Patent Application WO/2021/203912
Kind Code:
A1
Abstract:
Disclosed in the present application is an online prediction method for parameters in a copper converting process based on an oxygen bottom blowing furnace. The method comprises: establishing a bottom blowing converting furnace mechanism model according to a raw material input condition and on the basis of a material balance model, an energy balance model, and a multiphase balance model; establishing a bottom blowing converting furnace data driving model according to actual production data and on the basis of a crude copper grade neural network model, a slag ferrosilicon ratio neural network model, and a slag temperature neural network model between a target parameter and an input parameter; integrating the mechanism model and the data driving model by using an intelligent coordinator to obtain a bottom blowing converting furnace mixing model relating to a crude copper grade prediction value, a slag ferrosilicon ratio prediction value, and a slag temperature prediction value; and outputting final prediction values of the crude copper grade, the slag ferrosilicon ratio, and the slag temperature in a copper bottom blowing converting process by using the mixing model. The prediction method can effectively solve the problem that the existing prediction models and methods are poor in adaptability and not satisfactory in actual operation effect, and can significantly improve the accuracy of a prediction result.
