氧化燒損鋼坯在室溫狀態(tài)就產(chǎn)生氧化，只是氧化速度較慢而已，隨著加熱溫度的升高氧化速度加快，當(dāng)鋼坯加熱到11—12℃時(shí)，在爐氣的作用下進(jìn)行強(qiáng)烈的氧化而生成氧化鐵皮。氧化鐵皮的產(chǎn)生，增加了加熱燒損，造成成材率指標(biāo)下降。減少氧化燒損的措施：合理加熱制度并正確操作，控制好爐內(nèi)氣氛。脫碳鋼坯在加熱時(shí)，表面含碳量減少的現(xiàn)象稱脫碳，易脫碳的鋼一般是含碳量較高的優(yōu)質(zhì)碳素結(jié)構(gòu)鋼和合金鋼等。這些鋼都有其特殊用途，脫碳后，由于鋼的表面與內(nèi)部含碳量不一致，降低了鋼的強(qiáng)度和影響了使用性能。
