METHOD FOR CONTROLLING SPEED OF SUCCEEDING MATERIAL IN CONTINUOUS ROLLING
PROBLEM TO BE SOLVED: To execute joining of band plates stably and surely by making a succeeding material catch the preceding material within a limited target section at the time of executing rolling continuously while joining band plates in a rolling line such as a steel strip hot-rolling line. SOL...

| description | PROBLEM TO BE SOLVED: To execute joining of band plates stably and surely by making a succeeding material catch the preceding material within a limited target section at the time of executing rolling continuously while joining band plates in a rolling line such as a steel strip hot-rolling line. SOLUTION: A tip speed of the succeeding material is set in a standard pattern consisting of an acceleration region, a constant speed region and a deceleration region. In the acceleration region, an interval D1 between the preceding material and the succeeding material is calculated, the materials are transferred to the constant speed region at the interval D1 and transferred to the deceleration region after a holding time T. The interval D3 in the case that the tip speed is decelerated to the back end speed of the preceding material by the prescribed pattern is calculated, compared with a target gap value G and, when the D3 is |
