Innovative Method to Achieve Product Quality Convergence and Optimal Electrical Energy Consumption by Changing Motor Frequency in Batch Annealing

摘要

The batch annealing process is used for heat treatment of coils' output of the cold rolled process.In this process,high speed fan motors are used to generate strong convection currents and thermal heat convergence in all coil layers.Several factors could affect product quality grade.In this work by changing the motor speed,optimal frequency is reported to have the highest quality convergence and lowest energy consumption.For testing,frequencies of 45,55,65 and 75 Hz were tested.The results showed that there is highest quality convergence and lowest electrical energy consumption in frequency of 55 Hz.The practical solution represented in this work can be used to achieve optimal frequency for each condition.
