Title: Method for cooling steel sheet and device therefor
Inventor: FUJIBAYASHI TERUO
IPC: B21B45/02
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To obtain a cooling device by a laminar flow with which uniform cooling is enabled even when the upper surface of a steel sheet is cooled at lower cooling rate. SOLUTION: The cooling method of the steel sheet is constituted so that, by injecting cooling water on the upper surface of the steel sheet 22 so as to become the belt-shaped laminar flow from the slit nozzles 4 which are provided in the lower parts of cooling water headers 2 which are arranged above a steel sheet transporting line, the entire region in the width direction of the upper surface of the steel sheet 22 is cooled.  In such a case, when the cooling rate on the upper surface of the steel sheet 22 is lowered to a degree that uniform cooling is not attained by the cooling with the laminar flow, the injection amount of the cooling water is reduced corresponding to the cooling rate and also, by blowing compressed air into the vicinity of the outlet of cooling water in the slit nozzle 4 and jetting a fluid mixture of the cooling water and compressed air on the upper surface of the steel sheet 22, the upper surface of the steel sheet 22 is cooled.

No recording is brought to a level 0, and a recording of p dot is analyzed into recording made (m-1) times. A graduation of 1 dot is displayed by (m-1) bit, and thereby, in the case of n dot for one line, one line consists of n(m-1) bit. If a current applying time corresponding to saturated concentration of a recording is T, one common signal side is recorded (m-1) times at every T/(m-1) times, and if recording is made at every time, the concentration of the dot attains a saturation concentration. A given number of stages of a shift resistor and memory is decided from the number p of terminals.
