Abstract

PURPOSE:To prevent the shape failure generated immediately after starting the rolling by identifying a difference of wire rod speeds of the entry and the delivery of a wire rod, based on the roll diameters of a first stage stand and a final stand of a block mill, an correcting a roll gap value of a first stage stand in accordance with its result. CONSTITUTION:Roll diameters of each stand S1-S10 of a block mill are measured, and based on the measured roll diameters and a dimension of a rolled part, a gap value of the roll in each stand S1-S10 is calculated by a computing element 5. Subsequently, based on the roll diameter in a first stage stand S1 placed in the entry of a wire rod of the block mill, and the roll diameter in a final stand S10 placed in the delivery of the wire rod of the block mill, a difference or a ratio of wire rod speeds of the entry and the delivery of the wire rod is identified and in accordance with its result, a gap value between the rolls in a first stand S1 is corrected. Accordingly, an operation of the block mill can be started under a correct condition, and the generation of a shape failure of a product immediately after the operation can be prevented.
