| description | The invention provides a high-speed wire rod deformed steel bar with a small same-circle strength fluctuation difference and a surface oxide scale thickness of more than 10 microns and a production method of the high-speed wire rod deformed steel bar. The production method of the high-speed wire rod deformed steel bar comprises the steps of blast furnace molten iron smelting, molten iron desulfurization pretreatment, converter molten steel smelting, square billet continuous casting, high-speed wire rod rolling, spinning, inspection, packaging and warehousing which are sequentially carried out; during the high-speed wire rod rolling, the heating temperature of a casting blank is controlled to be 1050-1170 DEG C, the heating time of a steel billet is 80-120 minutes, and the initial rolling temperature is 950-1010 DEG C; the high-speed wire rod deformed steel bar comprises the following chemical components in percentage by weight: 0.21 to 0.25 weight percent of C, 0.55 to 0.70 weight percent of Si, 0.8 to 0.95 w |
