| description | The invention relates to the technical field of metallurgy, in particular to a preparation method capable of simultaneously producing continuous annealing and galvanizing DP780 dual-phase steel, which comprises the following steps of: smelting molten steel, continuously casting, heating, hot rolling, coiling and acid rolling to obtain a steel strip; and the steel strip is continuously annealed to prepare continuous annealing dual-phase steel, or the steel strip is continuously annealed and galvanized to prepare galvanized dual-phase steel. According to the method, two products of the continuously-annealed and galvanized DP780 dual-phase steel are produced at the same time through one component, the cost and the process difficulty are reduced, and the prepared dual-phase steel is excellent in performance.
本发明涉及冶金技术领域，具体涉及一种可同时生产连退、镀锌DP780双相钢的制备方法，包括如下步骤：钢水冶炼、连铸、加热、热轧、卷取、酸轧获得钢带；对钢带进行连续退火制得连退双相钢，或者对钢带进行连续退火、镀锌制得镀锌双相钢。本发明实现了一种成分生产同时生产连退、镀锌DP780双相钢两种产品，降低了成本及工艺难度，制备的双相钢性能优良。 |
