Element Mo, Cu were added into grey iron liquid, the type and content of inoculants, pouring time, cooling time, shake out time were adjusted to get acicular structure.
通过向灰铸铁中加入一定量的Mo、Cu等合金元素,并调整孕育剂的类型及其在铁液中的含量,同时调整浇注温度、冷却时间、落砂时间等工艺措施来控制针状组织铸铁的生成。
This study introduced the economictype X70 of hot strip which was designed by C-Mn-Cr-Nb alloy system and acicular ferrite microstructure,and produced by medium-thickness slab casting and direct rolling production line in Ansteel.
本文介绍鞍钢采用C-Mn-Cr-Nb系针状铁素体组织设计,在中等厚度板坯连铸坯连铸连轧生产线上研制开发经济型X70管线钢热轧卷板,产品具有高强度、良好的低温韧性和焊接性能,同时可大幅降低生产成本,应用于西气东输二线和中亚输气管线等国家重点工程。
This paper introduced X70 and X80 HRC with heavy thickness which were designed by low carbon,high niobium acicular ferrite microstructure,and developed on medium thickness slab continuous casting production line in Ansteel.
介绍了鞍钢股份有限公司采用低碳高铌针状铁素体组织设计、在中等厚度连铸坯连铸连轧生产线上研制开发特厚规格X70和X80级管线钢热轧卷板的情况。
Influencing of wearability of semi-worsted knit fabric with the fiber content and knitting stitch

Based on spike height resulting in break marks,the new technique of eliminating break marks by getting microstructure of quasi-acicular ferrite in hot strip mill was applied.
结果表明:产生横折缺陷存在临界的上下屈服点应力差,准针状铁素体组织可降低上下屈服点应力差,并使其低于这个临界值,更为重要的是,准针状铁素体组织使控制横折缺陷的工艺难度大大降低;钢中碳含量高、奥氏体晶粒粗、加速冷却速度快、加速冷却开始和结束温度低,有利于获得准针状铁素体组织,最佳的加速冷却开始和结束温度分别为先共析铁素体和珠光体开始转变温度。
