Embodiment Construction
[0090] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0091] Such as figure 1 As shown, an intelligent control method for the end point of converter steelmaking, the control method is realized by the following subsystems: data preprocessing subsystem, molten steel end point prediction subsystem, oxygen blowing amount and auxiliary material calculation subsystem, and model update subsystem.
[0092] 1) Data preprocessing subsystem: collect data from the database, perform data preprocessing, and determine the input variables of the endpoint carbon content and temperature prediction subsystem model through independence and correlation analysis to ensure the accuracy of the model; specifically include the following steps :
[0093] Step 1-1: Read n sets of converter data from the database, preprocess them, and remove irrelevant information such as smelting number, shift, name of furnace...
