PURPOSE:To perform block mill rolling at the optimum temperature and speed and to obtain an excellent wire rod by installing a set of coiler and discoiler, which are connected for securing a temperature controlling time, and a descaler between a bar mill and a block mill. CONSTITUTION:A blank material rolled by a bar mill 2 is wound up by a coiler 3 to enter a connecting device 6. A temperature controlling device capable of heating the material for keeping it warm and cooling it, etc. is incorporated in the device 6, to feed the material to a discoiler 4 after storaging a proper quantity thereof. The blank material delivered from the discoiler 4 is rolled into a wire rod by a block mill after cleaning its surface by a descaler. As the block mill 7 rolls the material always at the optimum temperature and speed independently of the rolling speed of mill 2, an excellent finished wire rod is obtained. |
