Abstract

PURPOSE:To connect preceding and succeeding strips to one piece by interposing a dummy strip formed in such a way that its thickness approaches from that of the preceding strip to that of the succeeding strip between both strips. CONSTITUTION:In the case of connecting a thick strip B to a thin strip A, a dummy strip C of which the thickness changes gradually from the thickness MA of the strip A to the thickness MB of the strip B is interposed between both. The length of the strip C is actually longer than the furnace length. Thereby, the abrupt change in weight is eliminated, the overriding and overlowering of joints are prevented and the furnace is operated smoothly despite change in strip thickness.
