摘要:
为了选择合理的热处理工艺使弯管的强度、冲击韧性以及表面硬度等指标达到良好的匹配,采用热模拟方法,通过拉伸、冲击、金相等试验,确定了X80钢级Φ1 422 mm大直径、厚壁弯管的热处理工艺。试验结果显示,随着淬火温度的升高,母材强度及表面硬度均明显升高,而冲击韧性显著降低;随着回火温度的升高,弯管屈服强度有所升高,抗拉强度有降低的趋势,而冲击韧性显示出先升高后降低的趋势。试验结果表明,当淬火温度为960 ℃,回火温度为560 ℃时,母材强度、表面硬度以及冲击韧性达到了良好的匹配,有利于获得稳定的组织。
Abstract:
In order to choose rational heat treatment process to make the strength of elbow, impact toughness, and surface hardness acquire a good match, the heat treatment process of X80 steel grade Φ1 422 mm large diameter thick wall elbow was determined by tensile, impact and metallographic tests adopting thermal simulating method. The tests results showed that with the quenching temperature rising, the strength of the base metal and the surface hardness increased, but the impact toughness obviously decreased; with the tempering temperature rising, the yield strength of elbow increased, tensile strength decreased, and impact toughness increased and then decreased. The results indicated that when the quenching temperature was 960 ℃ and tempering temperature was 560 ℃, the strength of the base metal and the impact toughness could acquire a good match, and it was beneficial to attain stable organization.
