  The drive to increase the efficiency of pulverized coal-fired power plants has led to raised steam conditions with operating temperature and pressure of 700℃/35MPa.A stress rupture life of 100000 hours at 750℃/100MPa stress as well as the metal loss of less than 2mm in 200000 hours are required for these advanced ultra-supercritical boiler tubes.This paper summarized the research on the four candidate superalloys,i.e.Inconel740H、617B、HR6W and Sanicro25 at domestic and foreign.

QB30冷镦钢常用于生产10.9级高强度紧固件。本文介绍了邢钢QB30冷镦钢的生产工艺和组织性能。通过成分设计、炼钢、轧钢生产工艺优化,盘条的化学成分、冷镦性能、夹杂物、脱碳层等均达到控制目标。用户使用结果表明,QB30盘条能够满足生产高强度缸盖螺栓的指标要求。通过成分控制和工艺优化,邢钢开发生产的QB30冷镦钢线材能够满足用户生产缸盖螺栓的要求,用户反馈使用良好。
本文利用光学显微镜矿相分析、扫面电镜分析,以及X衍射物相分析等方法对首钢秘鲁原矿的矿物组成和显微结构进行了分析和鉴定.结果显示,秘鲁原矿中主要矿物为磁铁矿、赤铁矿、脉石和硫化物,并含有少量的黄铜矿和磷酸钙,其中脉石以石英矿物为主,硫化物为FeS、Fe2S3 和FeS2(黄铁矿).硫化物主要以条带状、片状或斑状结构嵌布于铁氧化物基体内,并多与脉石矿物共生存在.硫化物和脉石矿物与铁氧化物具有较高的解离
通过利用喷吹法和四辊离心法制备矿渣棉,研究在不同制备方法条件下,矿渣棉其化学稳定性、表观特征、含水率及渣球含量与酸度系数之间的关系.结果表明:在满足成纤要求的前提下,高炉渣酸度系数应控制在1.2~1.4;利用喷吹工艺制备的矿渣棉直径较细,含水率较低,成纤率较低,渣球含量较高纤维质量较差;相对于喷吹工艺离心法制备的矿渣棉直径相对较粗,含水率大,渣球含量较少,成纤率较高,纤维质量较好.
