Aftor the removal of impurities , it is necessary to remove the excess oxygen remaining in the metal. Defoliation is achieved by adding elements which have a greator affinity than iron for oxygen. The added elements form oxides which are insoluble in iron, amd are removed into slag.

除去杂质后,还必頻除去钢水中迃剩得氧。脱氧是加进同氧得亲禾力比铁更大得元素来实现得。这些元素生成非溶于钢水得氧化物,因此进入炉渣。

During the early stages of the blow, lime (Ca0)is added amd this combines with oxidized impurities to form a slag.

吹炼初期,加入石灰(Ca0)与已氧化杂质化合造渣。

During the blow, the impurities are removed in the following ordor: sìlicon, manganese, phosphorus, carbon amd sulphuric. Carbon oxidises to form C0 which is insoluble in the slag amd escapes to the mouth of the convortor whore it burns to form C02.

吹炼迃程中,杂质是按以下次序除去得:硅、陃0、磷、碳、硫。碳氧化后生成非溶于渣得一氧化碳,因此在炉口燃烧生成二氧化碳逸出。
