Title: Descaling method for hot rolled steel plate
Inventor: AGEO HIDETAKA
IPC: B21B45/08
Filed: 1993-04-07
Abstract: PURPOSE:To nearly uniformly distribute the combined collision pressure of ejecting water from each of nozzles in the width direction of a steel plate with the value of pressure equal to or higher than a specific value and to smoothly distribute the combined amount of water when a hot rolled steel plate is descaled. CONSTITUTION:When the hot steel plate is rolled by a reversible hot rolling machine, the hot steel plate is manufactured by rolling several times descaling and cooling the steel plate. High pressure ejecting water ejected from plural nozzles is nearly uniformly distributed with a collision pressure equal to or higher than a specific value against the hot rolled steel plate in the width direction D. The pitch of nozzles L1 and ejecting angle theta1 are adjusted in compliance with the rolling conditions. Thus, the lap rate L2/L1 of high pressure ejecting water at the collision part on the hot rolled steel plate is determined and cooling capacity on the steel plate in the width direction is nearly uniform.
