摘要
介绍了中厚壁高强度缸体用20MnTiB调质无缝钢管的生产工艺和关键控制技术,以及产品的质量情况。采用"转炉/电炉炼钢+LF精炼+轧管+调质"工艺生产的中厚壁高强度缸体用20MnTiB调质无缝钢管钢质纯净,各项性能指标和尺寸精度等完全满足用户提出的技术要求,其综合性能优于27SiMn调质无缝钢管。
Described in the assay are the manufacturing process and key control techniques for the 20MnTiB quenched-tempered seamless steel tube for making of hi-strength, medium-heavy wall cylinder casing, and quality of the tube itself. Thanks to employment of the combined process of converter/electric steelmaking ＋ LF refining ＋ tuberolling ＋ quenching ＆ tempering treatment, the said seamless steel tube stays with high steel cleanness, and all the performance target values and dimensional accuracy up to the technical requirements as specified by the customer. The comprehensive properties of the said tube is better than that of the 27SiMn quenched and tempered seamless steel tube.
