摘要： PURPOSE:To economize the quantity of cooling water to be used, by feeding water to a cooling header intermittently by interlocking with the opening and closing operations of a cut-off valve. CONSTITUTION:An on-off valve 12 is provided in a pipe 11 for connecting a cooling water feed source 1 and a cooling header 2, a cut-off valve 21 is provided on an ejection port of the bottom part of the cooling header 2, and an operation timing control signal is sent from a control device 6 to the on-off valve 12 and the cut-off valve 21, respectively. At first, the on-off valve 12 is opened, the cut-off valve 21 is closed, water is fed to the cooling header 2, and a time t1 required for discharging water from the overflow is measured. After the time t1 has passed, the cut-off valve 21 is opened. Subsequently, when the cooling header 2 is operated normally, the time t2 when water is discharged from the overflow of the cooling header 2 is measured by simultaneously closing the on-off valve 12 and the cut-off valve 21. The opening and closing operations of the on-off valve 12 are made faster than the opening and closing operation time of the cut-off valve 21 by a time t2' obtained by multiplying said t2 by the safety rate (k
摘要翻译：目的：为了节省使用的冷却水量，通过与截止阀的打开和关闭操作互锁来间歇地将水送入冷却头。构成：在用于连接冷却水供给源1和冷却集管2的管道11中设置开闭阀12，在冷却集管2的底部的喷出口设置截止阀21，并且操作定时控制信号分别从控制装置6发送到开关阀12和截止阀21。首先，开关阀12打开，截止阀21关闭，水被供给到冷却集管2，并且测量从溢流器排出水所需的时间t1。在时间t1过去之后，截止阀21打开。随后，当冷却集管2正常运行时，通过同时关闭开关阀12和截止阀21来测量水从冷却集管2的溢流排出的时间t2。打开和关闭操作的开闭阀12的开闭动作时间比通过将t2乘以安全率（k <1）得到的时间t2'更快。

摘要： PURPOSE: To improve the accuracy of breadth of a finally obtained sheet product, by adjusting the rolling reduction of each stand of a roughing mill group.
CONSTITUTION: At a hot roughing process for a slab to be rolled later into a steel sheet, the rolling reduction to be given to the top and bottom of a slab is made larger at an upstream stand as compared with that at an intermediate stand, and is made smaller at a downstream stand wherein the spread of the slab is small. By thus varying the reducing schedule during a rolling pass for a single slab, the breadth constriction at the top and bottom of the slab is reduced. At an upstream stand, the rolling reduction to be given to a part having a skid mark is made smaller than other parts having no skid mark, in order to reduce the breadth deviation at the part having a skid mark. By the present method, the breadth fluctuation is prevented so that the accuracy of breadth is greatly improved.
