Hot rolling method of high toughness steel using thin slab |
| abstract |
(57) [Problem] To provide a hot rolling method capable of producing a high toughness steel material by performing hot rolling using a continuously cast thin slab. SOLUTION: This method is a hot rolling method for a high toughness steel material using a thin slab having a thickness of 155 mm or less, wherein the thin slab has a Nb content of 0.1%. A steel containing 0.1 to 0.50 mass%, which rapidly cools the rolled material to a bainite structure during hot rolling, and then reheats the rolled material to perform hot rolling to the final thickness. Hot rolling method for high toughness steel. Rapid cooling is 45 It is carried out by water cooling to a temperature of 0 ° C. or lower. The rapid cooling of the rolled material during the hot rolling is performed in a range where the thickness of the rolled material is 1.5 to 5 times the finished thickness. The reheating temperature is in a range from 850 ° C to 1050 ° C. |
