Title: Diagnostic device for thrust load of roll in rolling mill
Inventor: ANAMI EISHIN
IPC: B21B13/14
Filed: 1994-08-29
Abstract: PURPOSE: To enable the diagnosis of passing performance at the time of rolling and the control of mechanical deteriorating tendency of a rolling mill by measuring a force for shifting a roll in the axial direction by means of a pressure receiving cylinder and calculating a thrust load and monitoring. CONSTITUTION: A force for shifting a roll in the axial direction is received by a cylinder 1. The pressure of the cylinder 1 is measured by a pressure detector 3, and a thrust load is calculated by a computer 4 based on the area and pressure of the cylinder. When mechanical backlash caused by wear and corrosion takes place in the components of the rolling mill, the axial direction of the roll does not become perpendicular to the rolling direction. Unless they are precisely vertical to each other, a thrust load is generated in the direction of the roll axis as the component of frictional force in rolling. Abnormality of a rolling mill is found by monitoring the thrust load.

IPC: F28D5/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To raise the heat conductive coefficient of a boundary film on the side of fluid to be cooled, by letting cooling water flow dawn to the heat conductive wall face of an orthogonal passage whose top and bottom are open, and circulating this while evaporating this by the contact with atmospheric air for cooling, and cooling the fluid flowing in the spiral passage whose top and bottom are closed.
