今年三月份冶金部给我厂下达了試制廿辊軋机全套軋辊的光荣任务。由于我們认識到此項工作的意义,在冶金部鋼铁研究院的大力帮助下,于四月份就开始投入試制工作。經过一段时間的实践,初步摸索到了一些規律。这次試制的全套軋輥,有支撑輥、中間輥和工作輥三种(見图1)。支撑辊与中間辊系用Cr12鋼材制成,而较小的工作辊則用高鈷高速鋼鋼錠,經鍛造、机械加工、热
In March this year, the Ministry of Metallurgy issued a glorious task to our factory to test the full-scale roll of a 20-high mill. Since we recognized the significance of this work, we started trial production in April with the great help of the Steel Research Institute of the Ministry of Metallurgy. After a period of practice, initially found some rules. The trial of a full set of roll, there are support roll, the middle roll and work roll three (see Figure 1). The support roller and the middle roller are made of Cr12 steel, while the smaller work roller is made of high cobalt steel ingot, forged, machined and heated
