This paper presented a case study of soil remediation which took place at an industrial site in shanghai.In this paper,a remediation method which was efficient,cheap,safe and green was introduced.It combined the process of “biopile-soil improvement-soil phytoremediation” to achieve a better restoration effect.It covered an introduction of the remediation mechanism and the implementation process of this method,where engineering implementation included the construction preparation,soil excavation,screening and rushing,operation process,planting greenery,acceptance check monitoring,etc.In order to assess the effectiveness of this method,the pH value,electrical conductivity and organic matter content of the soil were analyzed and evaluated.The results showed that after remediation,the average soil pH value decreased from 8.9 to 8.0,the EC value increased from 0.30mS/cm to 0.64mS/cm,and the organic matter content increased from 0.93%to 1.26%,which could meet the target for the third level of“Greening Soil”(CJ/T340-2011).The results indicated that this method would achieve “As Remediation As Production” and stood in the forefront of remedial options for future projects.

采用调整调质态Q690钢板轧制后冷却方式的试验,考察轧后水冷、空冷和炉冷对试验钢屈强比的影响。试验结果表明:采用不同的轧后冷却方式,经两相区调质处理后,力学性能满足690级别高强钢的要求,但是屈强比(YS/TS)不同。采用轧后水冷的试样,冷却速度达到35℃/s,调质后软相组织铁素体含量最低,约为10％,YS/TS最高,为0.937.采用轧后空冷的试样,轧态组织中铁素体含量增加,调质后软相组织含量也
热轧高强钢板在热处理过程中,会在板带内部引起不均匀内应力,进而出现各种各样的板形不良情况,其后增设的矫直机就是为了改善板形,消除内部残余应力.矫直机的作用在于通过合理的辊缝设定使板带发生较大的弹塑性变形,实现多次反复弯曲以达到矫正板带板形平直性缺陷、消除钢板瓢曲和翘曲、降低残余内应力的目的.矫直机矫正作用的发挥对板带最终产品质量的控制起到重要的作用.矫直模型是矫直机及矫直技术的核心关键,其计算精度
D2钢是一种高碳高铬莱氏体型冷作模具钢,为了研究Nb对D2钢性能的影响,本文设计了当Nb含量分别为0.23％、0.46％、0.52％时,对D2钢力学性能和组织的影响。试样经过锻造,淬火和回火后进行各项性能测试,采用洛氏硬度计测试硬度,摆锤冲击韧性试验机上测量试样断裂的冲击功,热场发射扫描电镜观察组织,XRD测定残余奥氏体的量。试验结果表明,在不同热处理阶段硬度变化不大,当Nb含量为0.23％时各阶

非稳态轧制阶段一般伴随着张力的连续变化或轧制速度的连续变化,过焊缝轧制阶段是一种典型的非稳态轧制阶段,表现为轧制速度的连续变化.某钢铁厂某条高速冷连轧机组在过焊缝轧制时存在较为严重的板形缺陷,针对这一问题,结合现场实际情况,选取过焊缝轧制过程中几个不同的轧制速度时刻进行分析,通过有限元软件仿真分析了轧制速度改变对板形的影响,弯辊力改变对板形的影响,并在此基础之上提出了非稳态轧制过程中轧制速度连续变
本研究根据相似原理,按照修正的Froude准数相等的原则建立了一套1:4的钢包物理模型,通过对钢包底部透气砖的18个喷吹位置不同流量下进行混匀时间的测定,优化了钢包底部透气砖吹氩位置.结果表明:原型钢包底部透气砖位置不合理,导致钢包内钢液流动不合理,钢包中部区域出现较大的死区,混匀时间太长;通过综合考虑钢包底部透气砖在不同半径处以及同一半径的不同相对位置优化底部透气砖的位置,钢包内钢液的流动得到了
