Base on the situation analysis of copper matte smelting in P-S converter in the slag stage, this paper use modern BP neural network algorithm to realize the intelligent prediction of optimal flux addition through C programming. The module which is proved by the neural network toolbox of MATLAB can meet the demand of practical application. And the algorithm training time is greatly shortened in engineering operation. This module achieves the auxiliary judgment of prediction for the flux addition amount.

LCD1602应用于智能仪表、通信和办公自动化等领域,它的主要作用是显示ASCII码字符,因此又被称作"字符型显示器件"。利用点阵字形特点可自定义汉字字库让其显示汉字。
