摘要:
为了探究X80钢制管过程中应变强化规律及其影响因素,采用厚度22 mm不同厂家生产的6种X80热轧钢板,以相同的JCOE制管工艺生产出 Φ1 219 mm×22 mm规格钢管,并对6种钢板的拉伸性能以及钢板、钢管拉伸性能差异进行了检测。根据检测结果,从化学成分、显微组织等方面分析了制管前后拉伸性能变化的影响因素。分析结果显示,X80钢制管后屈服强度、屈强比有较大幅度的升高,不同材料的升高幅度不同。研究表明,拉伸性能的变化与合金成分无明显的规律,主要与显微组织有关。
Abstract:
In order to explore the strain strengthening rule and its influencing factors in the process of X80 steel pipe making, six kinds of X80 hot rolled steel plates with 22 mm thickness from different manufacturers were used to produce Φ1 219 mm × 22 mm steel pipe with the same JCOE pipe making process. The tensile properties of the six kinds of steel plates and the differences of the tensile properties of the steel plates and steel pipes were tested. According to the test results, the influence factors of tensile properties before and after pipe making were analyzed from the aspects of the chemical composition and microstructure. The analysis results show that the yield strength and yield strength ratio of X80 steel pipe are greatly increased, and different materials has different increase range. The results show that the change of tensile properties has no obvious rule with the alloy composition, but mainly related to the microstructure.
