PURPOSE:To improve comprehensive production efficiency by arranging a temporary winding and heat insulating device between the front and rear rolling stands and selecting lines by the combination of the kinds of steels and the dimensions of wire rod. CONSTITUTION:In a conventional arrangement of a front rolling stand 1, a rear rolling stand 2, a direct heat treatment device 3, and a winding device 4; one or two sets of temporary winding and heat insulating devices 5, 5' are arranged between the two rolling stands 1, 2. The rolling stands 1, 2 at the front and rear stages are always operated in full running to prevent the lowering of comprehensive production efficiency by using the device 5 in accordance with the difference of rolling pitch between the front and rear rolling stands 1, 2 due to the finished dimensions and kinds of steels of wire rods and the necessitites of intermediate heating and heat treatment. Further, a heat treatment device 3 and a winding device 4 can be directly added. |
