浦钢公司铁水KR脱硫工艺实践戴超1,徐熙2(1.上海市上海天麟安全管理咨询有限公司2.宝钢集团浦钢公司 炼钢厂,上海 200949)摘 要:简要介绍了宝钢集团浦钢公司的铁水KR法脱硫工艺和装备,其具有铁水原料条件不稳定和技术装备先进,自动化程度高的特点.为适应COREX铁水硅高的特点及保证KR的脱硫效果,对开工用铝渣的成分进行了调整,并且采用2次搅拌法脱硫,从热试第1炉的效果看,脱硫效果明显.宝钢集团浦钢公司炼钢厂铁水KR脱硫设备的投产使用,标志着浦钢百年老厂的涅槃重生,同时也是在COREX铁水条件下脱硫的全新......
Effects of pretreatment of substrates on the preparation of large scale ZnO nanotube arraysCHOU Kuo-ChihDepartment of Physical Chemistry, University of Science and Technology Beijing摘 要:pretreatment was introduced to prepare ZnO coated films......
enhanced chemical vapor deposition (PECVD) were presented. Among lots of influential parameters, the effects of the catalytic film thickness and the pretreatment plasma power on the growth of CNTs were investigated. The results show that the size of catalytic islands increases by increasing the thickness of catalytic layer, but the density of CNTs decreases. The pretreatment duration time of 30 s......
