摘要： PROBLEM TO BE SOLVED: To improve biting property of a material to be rolled at a start of rolling and to easily prevent a rolling slippage mark at its bite, by making contact state between rolling rolls and the material surface contact with a minimal arrangement of facility.
SOLUTION: After rough rolling, a rough rolled bar is wound into a coil and then put into a coil box to be retained not less than 1 minute and not more than 5 minutes at not lower than 1,000°C and not higher than 1,300°C. This makes an outer portion of the top of the rough rolled bar recuperate heat and become easier to be worked. After the coil is uncoiled, its top tail portion is cut off and then the top portion after cutting is formed into a concave wedge shape in a radius of curvature of not less than 350 mm and not more than 500 mm at least in one side or both side of upper and lower surfaces. The bar is transferred to a finish rolling mill by conveyer rollers and bitten by the finish rolling mill. This rolling method can reduce the rolling slippage mark and can apply a large rolling amount.
