本文是介绍苏联捷尔任斯基工厂Г.П.克利明柯工程师写的280和330轧机利用围盘轧制角钢、槽钢的经验。280和330轧机各由三列组成(图1)。第一列550粗轧机包括一架辊径为575mm 的三辊式轧钢机,该轧机是330和280轧机共用的粗轧机。它把180×180mm 的钢坯经9道轧成60×60mm 的钢坯。由550轧机轧出的60×60 mm 的钢坯,用辊道输送到热剪。一部份剪切过的钢坯经过加热炉送到280轧机;另—部 This article is about the experience of the 280 and 330 mills written by Credenko engineers from the Czech Republic, the Dzerzhinsky mill, for the use of walled rolled angle and channel steel. The 280 and 330 mills each consist of three columns (Figure 1). The first 550 roughing mill consists of a 3-roll mill with a 575mm roll diameter, which is a roughing mill common to the 330 and 280 rolling mills. It will be 180 × 180mm billet rolled into 60 × 60mm by 9 billet. The 60 × 60 mm billets rolled off by the 550 rolling mill are conveyed by roller conveyors to hot shears. A portion of the cut billet was sent to the 280 mill via a heating furnace; the other part
