| titleOfInvention | Manufacturing method of high workability and high strength hot rolled steel sheet |
| abstract | (57) [Problem] To provide a method of manufacturing a hot-rolled high-strength steel sheet which is uniform in material over the entire length and width of the coil and has excellent material stability in the coil. SOLUTION: The method for producing a high-workability, high-strength hot-rolled steel sheet includes: By weight%, C: 0.07 to 0.14%, Si: 0.9 to 1.4%, Mn: 1.0 to 1.8 %, P: 0.04% or less, S: 0.005% or less, Al: 0.01 to 0.1%, N: 0.0 06% or less, Ca: 0.001% or less, the balance is substantially Fe After finishing rolling of a steel slab consisting of austenite in the single-phase region, Tc (° C): winding at a temperature in the range of 450 to 650 ° C, ferrite single-phase or, in addition to ferrite, one or more of pearlite and bainite After the hot rolled sheet containing ｛Ac 1 + 20 × (650-Tc) / 200｝ to ｛Ac 3 -20 × (Tc-450) / 20 After maintaining the temperature range of 0 ° C for 10 seconds or more, the cooling rate is 10 ° C / Cool to a temperature range of 300 to 500 ° C at a temperature of at least s and hold at that temperature range for at least 20 seconds to obtain a steel sheet containing 3 to 10% of retained austenite. |
