PRODUCTION OF STEEL SHEET FOR WORKING, EXCELLENT IN FORMABILITY, BY USING CONTINUOUS HOT ROLLING PROCESS

PROBLEM TO BE SOLVED: To improve the material of a hot rolled steel plate, to improve the limit if yield lowered by the inferior material of the heat end, and to provide a method for continuously producing a steel sheet for working, excellent on formability, by precipitating the precipitates of MnS...

Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the material of a hot rolled steel plate, to improve the limit if yield lowered by the inferior material of the heat end, and to provide a method for continuously producing a steel sheet for working, excellent on formability, by precipitating the precipitates of MnS and AlN in the austenitic region. SOLUTION: A hot roller steel plate can be produced by heating a steel slab of =0.5S bending strain rate. Subsequently, the steel plate is held for >=3sec at
