Title:
CONTROLLED COOLING METHOD FOR DIFFERENTIAL THICKNESS STEEL PLATE
Document Type and Number:
Japanese Patent JP2005262273
Kind Code:
A
Abstract:
To provide a method for obtaining a differential thickness steel plate superior in flatness by means of a controlled cooling.
When the differential thickness steel plate, whose thickness is different in a longitudinal direction, is hot rolled, and then, is subjected to the controlled cooling immediately, in a roller straightening machine installed on the entrance end of the controlled cooling equipment, the straightening is performed with a passing speed synchronized to that of the controlled cooling equipment, wherein the position of a roll in the straightening machine is adjusted in accordance with the thickness of the steel plate passing therein.
