摘　　要：随着钢铁产品市场竞争的不断加剧,热轧装备水平的不断提高,2 mm以下的热轧薄板产品已具备替代部分冷轧薄板及以冷轧薄板为基板的涂层产品的可能。由于2 mm以下热轧薄板产品比例的不断增加,传统热轧产线配置的热轧精整机组的功能和产能需要与之匹配。结合国内冷、热轧薄带钢切边重卷机组的现状,探讨了与2 mm以下热轧薄板产品配套的切边重卷机组的选型及提高机组生产能力的方案。选型方案首次提出了双开卷机设计,以提高机组产量。该设计不仅节省投资、降低生产成本,同时还可以改善热轧薄板板形质量,满足替代部分冷轧产品的需要。As the market competition gets more and more intensified, the hot rolling equipment is being improved continuously. The hot rolled thin strips with a thickness below 2 mm can be used as the substitutes for some cold rolled thin strips as well as certain coated products using cold rolled thin strips as the substrates. As the proportion of hot rolled thin strips with a thickness below 2 mm increases continuously, there has to be a match in function and capacity between the finishing units and the conventional hot rolling lines. This paper introduced the current status of the trimming- recoiling lines for hot and cold rolled thin strips in China, and discussed the selection of trimming- recoiling equipment for hot rolled thin strips with a thickness below 2 mm. In addition, measures to increase the production output were also discussed. The use of double decoilers was proposed for the first time to raise the production output. Such a design will not only reduce the investment and the production cost, but also improve the flatness of the products, thus helping realize the substitution of hot rolled thin strips for some cold rolled strips.
