Abstract:
A rolling mill equipped with an on-line roll grinding system comprising:a grinding wheel positioned to face one of a pair of mill rolls for grinding said mill roll; grinding wheel moving means for pressing said grinding wheel against said mill roll; and grinding wheel traverse means for moving said grinding wheel in the axial direction of said mill roll; wherein said grinding wheel comprises a wheel disk and an abrasive layer formed on one side of said wheel disk facing said mill roll; said wheel disk having an elastically deforming function to absorb vibration transmitted from said mill roll; and said on-line roll grinding system further comprising load detecting means for measuring a contact force between said grinding wheel and said mill roll; and means for controlling said grinding wheel moving means to change the contact force measured by said load detecting means so that a grinding rate of said grinding wheel on said mill roll is changed, for thereby grinding said mill roll into a predetermined roll profile.
