摘　　要：对 40炉韶钢钢材基本数据统计分析表明 :韶钢钢材化学成分具有粤北大宝山等共生铁矿资源特色 ,一些低熔点元素和铜含量较高 .统计分析导出的成分、组织与性能之间的回归关系式可供生产部门借鉴 .A statistical analysis of 40 heats of SGIS's steel products showed that they were high in copper and low_melting-point elements, thus being characteristic of the multi_elements_coexistent iron ore resources formed in Northen Guangdong province represented by Dabaoshan Mine. The chemical composition_microstructure_mechanical property relationship regressed from the statistical analysis can be used as a guidline by the makers and users of the steels.
