作者 唐天博 孟伟 周勇 《金属世界》 CAS 2023年第2期60-65,共6页
本钢1880线为薄板坯连铸连轧产线,与同内同类产线一样,它具有薄规格轧制能力强,综合能耗低的特点。但是,由于其精轧机架少,轧制负荷大、产品规格排产又偏薄等原因,轧辊在机多发裂纹、掉肉、剥落甚至断辊等失效。本文通过对轧辊失效形式... 本钢1880线为薄板坯连铸连轧产线,与同内同类产线一样,它具有薄规格轧制能力强,综合能耗低的特点。但是,由于其精轧机架少,轧制负荷大、产品规格排产又偏薄等原因,轧辊在机多发裂纹、掉肉、剥落甚至断辊等失效。本文通过对轧辊失效形式的分析,结合无损探伤技术,采取点检等手段,使1880线轧辊在机失效得到了有效的管控。在研究过程中,积累的一定经验和数据,很值得在钢铁同行间参考,具有一定的推广价值。 展开更多

本钢1880热轧(FTSR)产线为2005年投产的薄板坯连铸连轧产线,与国内同类产线一样,它具有薄规格轧制能力强,综合能耗低的特点。其荒轧机架工作辊主要采用高Cr复合铸钢材质,2019年2月和8月,某厂家的荒轧高铬钢材质的工作辊在使用过程中出... 本钢1880热轧(FTSR)产线为2005年投产的薄板坯连铸连轧产线,与国内同类产线一样,它具有薄规格轧制能力强,综合能耗低的特点。其荒轧机架工作辊主要采用高Cr复合铸钢材质,2019年2月和8月,某厂家的荒轧高铬钢材质的工作辊在使用过程中出现传动侧辊颈断裂事故,造成整条产线停浇待产,生产连续性被打破。针对这一情况,分析出荒轧工作辊辊颈断裂的共性问题和原因——辊颈存在热节。结合无损探伤检测方式提出了相应的预防管控措施。措施实施后,断辊问题基本控制,后续轧辊使用过程中未再发生此类事故,解决了生产问题。 展开更多

Russia, after realizing that it will not be truly accepted as a member of the western world, has shifted towards promoting the integration of the Eurasian areas in order to lay the geopolitical foundations for its renewed ambition as a great power. In January 1995, the three countries of Russia, Belarus and Kazakhstan established a customs union. In March 1996, Kyrgyzstan officially announced that it would be joining the union, and the four-country customs union was established. It was aimed at coordinating the economic reform pace of the four member countries, as well as accelerating economic integration between them. In February 1999, Tajikistan also joined, and in 2000, the aforementioned five countries signed the treaty that transformed the customs union into the Eurasian Economic Community. On May 31, 2001, the Interstate Council of the Eurasian Economic Community held its first meeting in Minsk, the capital of Belarus, declaring the official founding of the Community. 展开更多

Europe,which has established a model of social stability and the pursuit of a high-quality of life since WWII,is facing the most severe economic,social,political and security challenges since the end of the Cold War.The euro crisis,the rise of far-right political forces,terrorist attacks inspired by international terrorism and the Europe-Russia confrontation triggered by the Ukraine crisis are among them.In 2015 the European Union(EU)and its member states will focus on economic issues,but after the Paris terrorist attack,they have to invest more to contain the extreme internal threats.In terms of external relations,Europe will regard the Middle East,eastern neighbors like Ukraine and major powers like Russia,the U.S.and China as its major diplomatic concerns.It is vital for the European Union to solve its economic difficulties. 展开更多
