Abstract

PURPOSE:To allow to reach the aimed line speed with making the strip temp. at each furnace exist constant by varying the unit speed and furnace temp. corresponding with the furnace having longest time for varying its temp., and by confirming the end of unit operation of the furnace temp. prior to the variation of unit speed and flurance temp. by the same procedure.
