Zusammenfassung: | The invention discloses a shallow stamping grade DC01 grade steel production method, and belongs to the technical field of steel. The shallow stamping grade DC01 grade steel production method comprises the following steps of smelting, continuous casting, rough rolling, IH furnace heating, finish rolling, cooling, and coiling to obtain a hot rolled material. The method comprises the concrete steps of S1, smelting: smelting in a converter, an RH furnace and an LF furnace according to the proportion of steel grade chemical components, wherein the LF furnace smelting adopts early-stage slagging-off and slag reconstruction operation; S2, continuous casting: performing continuous casting on molten steel treated by the LF furnace, wherein the thickness of a casting blank at an outlet of a continuous casting machine is 70 to 110 mm; S3, hot rolling, wherein the rough rolling inlet temperature ranges from 960 DEG C to 1010 DEG C, the rough rolling outlet temperature ranges from 950 DEG C to 1010 DEG C, the thickness o |
