采用3．85％～4．07％CE成分铁水，在实验室条件考察了合金元素铜及铬对强度和组织均一性的影响。结果发现，合金元素能有效提高强度，对断面敏感性的作用因成分（CE）不同而有所不同。合金化能改善珠光体显微组织均匀性。
Using 3.85% ~ 4.07% CE content of hot metal, in the laboratory conditions investigated the alloy elements copper and chromium on the strength and the uniformity of the organization. The results showed that alloying elements can effectively improve the strength of the cross-sectional sensitivity of the role of components (CE) vary. Alloying can improve pearlite microstructure homogeneity.
