Title: Method for cooling steel plate
Inventor: HARAGUCHI YOICHI
IPC: C21D9/52
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To control a temperature distribution at the time of the completion of cooling, and to make it possible to apply to the plate with a large taper such as a large plate thickness ratio by determining the speed of a tip part passing through the inlet and the outlet of a cooling device after calculating it preliminarily, determining a specific acceleration or deceleration after calculating it, and controlling the transfer speed of the plate. SOLUTION: Solutions to be obtained are only transfer speeds at the time of the start and the completion of cooling, and a speed pattern can be obtained in a comparatively short time. Also, by changing the transfer speed straight, a control is performed so that a cooling pattern is increased and decreased at even intervals along the longitudinal direction of the plate. Therefore, a cooling time in each position in the longitudinal direction of the plate is changed almost continuously. Consequently, for a cooling completion temperature, the continuous temperature distribution can be obtained from a tip part to a rear end, and a uniform characteristic can be obtained to the whole of the tapered plate. Also, since the transfer speed is a constant acceleration pattern, it is easily used in an actual operation.  Further, according to the taper size and the plate thickness of the plate, it can cope with a plate with a large taper as well with a proper cooling pattern.
