摘　　要：某高速线材生产线是20世纪90年代初引进的美国摩根五代技术,设计产能38万t。随着线材深加工行业生产技术及效率的不断提高,市场对线材产品尺寸精度、表面质量以及产品机械性能等提出更高要求。为了满足市场变化,提升产品竞争力,高速线材生产线增设减定径机组。文章介绍了产线增设减定径机组改造涉及的机械、电气、动力等设备施工改造情况,对精轧机组和减定径机组的辊缝重新进行设计,并给出其各架次R值,并对机组投产后出现的不同事故类型和解决方法做了经验总结。The 5th generation American Morgan technology was introduced in the early 1990s for a production line of high speed wire rod and its design capacity was 0.38 million tons.With the constant improvement of production technology and efficiency for the deep processing industry of wire rod,the requirements of dimensional accuracy,surface quality and mechanical properties for wire products in the market are higher.In order to satisfy the market changes and improve product competitiveness,the size reducing mill is added in the production line of high speed wire rod.In the paper,it is introduced the construction transformations of such types of equipment as mechanical,electrical and power as well as the roll gaps of finishing rolling unit and size reducing mill are redesigned.Moreover,the R values of each stand are given as well as different accident types and solutions after the mill put into production are summarized.
