| titleOfInvention | Titanium-containing low-manganese high-strength steel and temperature and heat preservation time-based binding control method thereof |
| abstract | The invention discloses titanium-containing low-manganese high-strength steel which comprises the following components in percentage by mass: the components and the mass percentage thereof are as follows: 0.04-0.12% of C, 0.2-0.40% of Si, 1.00-1.49% of Mn, 0.08-0.14% of Ti, less than or equal to 0.002% of S, less than or equal to 0.002% of O, and the balance of Fe and inevitable impurities; the preparation method comprises the steps of converter smelting, argon station titanium microalloying, vacuum treatment, pouring, temperature parameter linkage control, coiling and stacking slow cooling. According to the invention, a two-step titanium microalloying method is adopted and a linked rolling control process based on temperature and soaking time is combined, so that the strength fluctuation of a steel plate can be effectively reduced, the influence of N element on free titanium can be ignored, and the obtained steel effectively has good mechanical strength, tensile property, impact resistance and welding property under the condition of low manganese content; and the arranged preparation process is simple, low in cost and suitable for popularization and application. |
