【摘要】 介绍了攀钢重轨钢非铝脱氧工艺。在满足钢中脆性夹杂物控制的前提下,采取"预脱氧+终脱氧"的工艺,达到钢液脱氧良好,钢轨内部质量大幅提高,钢轨T[O]、[Al]及氧化物夹杂评级完全满足200km/h高速铁路钢轨标准的要求。更多还原

【Abstract】 It is introduced that the development and application of non-aluminum deoxidizing technology for rail steel in PZH Steel. Combining pre-deoxidizing technology with final-deoxidizing process, the internal quality of rail steel was greatly improved, and finally come up to 200 km/h high-speed rail standards.更多还原
