摘　　要：指出棒材连轧机粗、中、精轧机架轧辊的理想选择应是：粗轧前段为珠光体－铁素体球墨铸铁轧辊；粗轧后段、中轧机架为珠光体球墨铸铁轧辊；精轧机架为针状组织球墨铸铁轧辊，同时指出，轧辊制造方法的选择比轧辊材料选择更重要。采用离心浇注复合轧辊有利于提高轧辊的综合性能。The optimal selection principle of roll material for continuous bar mill as follows:the pearlite-ferrite nodular cast iron roll for the preceding roughing stands,the pearlite nodular cast iron roll for the later roughing stands and intermediate stands,and the needle nodular iron roll for finishing stands.At the same time,the paper points out that the selection of the manufacture method of roll is more important than its material,and the centrifugal casting method can improve the synthetic properties of roll.
