PURPOSE:To reduce the occurring range of scratches by acceleratedly operating only a table part on which the strip top part is put by a lead speed and synchronizing a speed of other table parts with a delivery speed of a finishing mill. CONSTITUTION:Contacts A and B are set in a speed control system of a hot run table. The contact A is ON to acceleratedly operate only the alpha section by a lead speed when the top of a strip 2 delivered from a finishing mill 1 is put on the #1 section; the contact A is OFF and the contact B is ON to acceleratedly operate only the #2 section when the top of the strip 2 is transferred onto the #2 section. Sequentially, only a section on which the strip top part is put is accelerated and a speed of other sections is synchronized with a delivery speed of the mill 1. Slips and occurrence of scratches are reduced because of reduction of accelerated operation ranges.
