Latest Patents
Among his latest patents is a device and method for shifting the work roll of a cluster mill. This invention utilizes a roll shifting cylinder that pivots a lever arm to shift a work roll via a thrust bearing. A control unit performs auto-positioning control based on a shift amount performance value detected by a shift amount detection sensor, ensuring that a target roll shift position is achieved. During the rolling operation, a constant clearance amount is maintained between the end surface of the work roll and the thrust bearing, effectively utilizing a chockless mill as a work roll shift mill.
Another notable patent is a surface cutting apparatus for hot-rolled steel products. This invention addresses the cutting of the top and bottom surfaces of a hot-rolled sheet by rotating milling cutters that hold the sheet in place. The cutting resistance is controlled by adjusting the cut depth, ensuring that the tension produced during cutting remains below the breaking strength of the joint portion, thus preventing breakage of the hot-rolled sheet.
