えられることを特徴とする、４重圧延機の運転方法。[Scope of Claim for Utility Model Registration] A roll housing, a work roll supported by each chock in the window thereof, and a backing roll supporting the chock from behind can be pressed in mutual directions by a hydraulic pressure reduction device. Each component inserted into the window and/or the roll chock is also provided with a pressure medium cylinder which keeps both work rolls open even after the passage of the material to be rolled. In a method of operating a quadruple rolling mill in which each chock of the side support rolls is further provided with a separate pressure medium cylinder, each pressure medium cylinder 17 provided in the chock 4 of the lower support roll is directly or indirectly supporting the chock 7 of the upper backing roll; And in these pressure medium cylinders 17, during rolling with a slight rolling force of less than 15% of the maximum rolling force, a pressure which is kept constant at least 15% of the maximum rolling force of this rolling mill is high. Guys 4
A method for operating a quadruple rolling mill, characterized in that a constant force of 0% or less that cannot be changed is applied.
