<p>PROBLEM TO BE SOLVED: To supply a rolling material without interrupting a continuous rolling by making a space between a rolling material extracting tip of a heating fur nace and a joining start point longer than the rolling material length. SOLUTION: This device has extracting lines 2 at a forward direction inner part 23 end of the heating furnace 1, the number of which is equal to that of the strands. A joining device 3 is arranged on its extended line, and a rolling mill is at a point further ahead. Length of the rolling material is equal to the longest one of materials installable in heating furnace. Since one part of the roping material to be joined is travelling while it is rolling, a travel joining device is used as the joining device 3, so that it can travel a given distance between the furnace 1 and a rough rolling mill 4. Space between a rolling material extraction end 10 of the furnace 1 and a setting start point 11 of the joining device 3 is made to be at least longer than the rolling length. A roll starting point of the first roping material at each of strands 20, 21, 22 is so adjusted that when the end part of the first material passes the joining start point, a tip of the following material reaches the joining start point.</p> |
