Title: Method for rolling steel material
Inventor: KATO OSAMU
IPC: B21B27/10
Filed: 1991-11-26
Abstract: PURPOSE:To improve wear resistance and seizing resistance of roll for rolling steel material. CONSTITUTION:The composition of a oxidized film on the surfaces of a rolled stock and roll in rolling is controlled. That is, the oxidized film of the rolled stock is preliminarily made in basicity of >=1 and the oxidized film of the roll is made in basicity of <=1. In such a way, iron ion and oxygen ion are moved from the former to the latter in the high temp. part of friction surfaces in rolling, so the oxidized film on the roll surface is made thicker and stabilized. The direct contact of the fresh surface of the rolled stock with the base material of roll is prevented with the oxidized film of roll and temp. increase of roll surface is reduced by allowing to oxidized film to serve as a thermal insulation, so it is extremely effective to the prevention of wear and seizing of roll.

Title: Axial xenon vibration suppressing method
Inventor: TOCHIHARA HIROSHI
IPC: G21D3/08
Filed: 1993-11-18
Abstract: PURPOSE:To suppress axial xenon vibration effectively and easily by making the relative difference of xenon quantity and iodine quantity between the upper half and lower half of a reactor core respectively DELTAx and DELTAII, displaying them on X-Y coordinates, and operating a control rod in the direction of reducing each relative difference. CONSTITUTION:DELTAIX represents the relative difference between the quantity of xenon produced with iodine, a fission product, as a parent nucleus in the upper half of a reactor core, and the quantity of xenon produced in the same way in the lower half of the reactor core. DELTAII represents the relative difference between the iodine quantity in the upper half of the reactor core and the iodine quantity in the lower half. In the case of placing DELTAIX on an X-axis coordinate and DELTAII on a Y-axis coordinate, axial xenon vibration describes a curve corresponding to the vibration stability. On this coordinates, the change of xenon vibration with the lapse of time is displayed by a clockwise elliptic orbit, and in order to stabilize the vibration, it is understood that the ellipse has to be made small so as to approach a zero point, that is, a control rod is operated in the direction of reducing the variation of DELTAIX, DELTAII. Xenon vibration can be thereby suppressed even by an inexperienced operator.
