本文主要介绍西德曼内斯曼·德马格·米尔厂最新制造的第一台带液压快开系统的阿塞尔轧管机,这种改进型阿塞尔轧管机是大冶钢厂1988年引进的,在设备结构上有别于目前的特朗斯瓦尔三辊轧管机,在生产范围上有更大的灵活性,该机对于国内φ76mm无缝厂的热轧技术改造较为适宜。本文还介绍了该种轧机的特点、操作方法及工艺编制方法等。 This article mainly introduces the first newly manufactured Assel rolling mill with hydraulic quick-open system manufactured by Sidmanmansmann Demag Mill, which is an improved Assel rolling mill which is manufactured by Daye Steel Introduced in 1988, the equipment structure is different from the current TRW’s three-roll pipe mill and has more flexibility in the production range. The machine is suitable for the hot-rolling technology reform of the φ76mm seamless factory in China . This paper also introduced the characteristics of the mill, operating methods and process preparation methods.
