由于钢铁冶炼中脱碳过程存在很多不确定因素,碳含量难以在线检测,终点控制难以及时准确地判断。对此系统采用S7-300 PLC作为控制器,创建非等间隔序列灰色优化模型功能块来预测冶炼过程的碳含量,并通过组态画面实时显示其变化趋势。试验结果表明,非等间隔序列灰色优化模型的相对误差在-6.4%与3.06%之间,能够很好地对碳含量进行终点预测。

In the decarburization smelting process,carbon content is difficult to be detected on-line and the end-point is difficult to be accurately determined in time.Here S7-300 PLC is used as controller to create a non-equidistance GOM to predict carbon content and make the configuration to demonstrate the variation trends.Experiment results show that the relative error of the GOM is between-6.4% and 3.06%.It can predict the carbon content of the end point precisely.
