<p><P>PROBLEM TO BE SOLVED: To provide a rolling mill speed control method for controlling the speed of a rolling mill when rolling a work to be rolled. <P>SOLUTION: The torque estimation value required when rolling a work by a rolling mill is calculated based on the draft and the rolling speed set in the rolling mill and the material characteristic of the work. The speed control gain which is a control parameter of the rolling speed of the rolling mill is determined based on the calculated torque estimation value. The speed of the rolling mill is controlled based on the determined speed control gain. Most preferably, the torque estimation value is the biting torque estimation value when the work is bitten into the rolling mill, and the speed drop of the rolling speed when the work is bitten into the rolling mill is controlled. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
