Embodiment Construction
[0060] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0061] The invention provides a method for predicting electric energy consumption of a combined acid-rolling unit based on a cold-rolling mathematical model.
[0062] Such as figure 1 As shown, the method includes the following steps:
[0063] (1) Moment prediction: After the rolling plan is issued, calculate the rolling moment, tension moment, and loss moment of each stand according to the raw material specifications and finished product specification parameters of the strip;
[0064] (2) Prediction of rolling mill power consumption: calculate the required power consumption of each stand according to the rolling torque, tension torque and loss torque calculated in step (1);
[0065] (3) Prediction of power consumption of the coiler: calculate the powe...
