To provide a pressure fixing structure for a housing and a rolling roll group which can realize a stable rolling operation without being adversely affected by a reaction force from keeper plates in an axial direction when the keeper plates are installed in both of a rolling pass direction and a roll axial direction in a rolling mill performing a tilting control, and to provide a rolling method and a reduction position zero point adjusting method in the rolling mill having the pressure fixing structure.

In the rolling method and the reduction position zero point adjusting method, a fixing structure of the housing and the rolling roll group by pressure fixing type keeper plates in a rolling mill to perform the tilting control has a keeper plate to fix the rolling roll group in the rolling pass direction and a keeper plate to fix the rolling roll group in the roll axial direction. There are provided a rolling method and a reduction position zero point adjusting method in the rolling mill having this pressure fixing structure.
