其中化學(xué)成分要求為嚴(yán)格，它是判定鋼材質(zhì)量的主要依據(jù)。為了保證線材質(zhì)量均勻，性能一致，其含碳量波動(dòng)的范圍應(yīng)當(dāng)盡可能少，不僅要求同一澆注批號(hào)的碳含量波動(dòng)小，而且要求同一鋼號(hào)的含碳量都相同，以保證同一鋼號(hào)的線材質(zhì)量穩(wěn)定。另外要限定偏析值保證線材成分及性能均勻。對(duì)碳鋼線材而言，含碳量每增加.1％則抗拉強(qiáng)度就相應(yīng)增加78.4MPa，而延伸率下降4％。所以通常要求同批線材含碳量波動(dòng)不超過.2％。目前我國標(biāo)準(zhǔn)規(guī)定的允許碳含量波動(dòng)范圍都比較大（注意收集實(shí)習(xí)廠家的資料）。
