Abstract

PURPOSE: To manufacture steel hoop excellent in precise punchability, by hot rolling a low alloy steel slab of small S content to steel hoop, by winding it into a coil, then by spheroidizing it.
CONSTITUTION: A low alloy steel slab is manufactured which is composed of C 0.10W0.50%, Si<0.35%, Mn 0.30W1.50%, S<0.01%, in addn., one or more members selected from the group consisting of Ni<2%, Cr<1.2%, Mo<0.3%, V< 0.3%. The steel is desulfurized with 0.3W1.0kg desulfurizing agent packed in a mild steel pipe per ton steel, the desulfurizing agent which is composed of Ca-Al powder in a ratio of Ca to Al of 10W6:0W4. The slab is hot rolled at a final draft of 15W25% so as to refine the austenitic crystal grains while restraining transformation into bainite. The hoop is cooled to 500W570°C and is wound, then carbide is spheroidized. Hereby steel hoop excellent in precise punchability is manufactured.
