Title: Continuous hot rolling method
Inventor: HISATSUNE TAKASHI
IPC: B21B27/02
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To make the timing of rolling and joining coincide in the width direction and to uniformize joining strength in the width direction by rolling a sheet with a 1st stand so that the sheet crown ratio in the vicinity of the joining part on the inlet side of the 1st stand of a finishing mill is larger than the sheet crown ratio on the outlet side. SOLUTION: When the sheet crown ratio in the vicinity of the joining part on the inlet side of the 1st stand of the finishing mill is expressed by C0 and that on the outlet side of the 1st stand by C1 , rolling is executed with the 1st stand so as to be C1 <C0 . In the case a convex crown is imparted to a 1st work roll of the finishing mill, it is preferable to impart in the amount of roll crown of >=20 μm/radius per the barrel length and by a curve which is higher than the 1st order and not higher than 2nd order. In the case a concave crown is imparted to the work roll of a roughing mill, it is preferable to be imparted in the amount of crown of >=200 μm/radius and by the curve which is higher than the 1st order and not higher than the 2nd order. Because the initial joining rate is reduced, joining time is shortened.
