在其他条件相同下,钢的质量以其含有杂质的多少而不同,如磷、硫、氢、氮、氧和非金属夹杂物。在碱性炉衬弧光电炉中炼钢时,当熔化终了和氧化期开始时去磷,然后在氧化后半期伴随着钢液沸腾去炭和氢、氮气体。在还原期钢液清除氧、硫和非金属夹杂物。在氧化期钢液有力地沸腾保证着钢中气体含量的降低,但是尚不能去除还原期钢液中的氢、氮、气体。曾经提出了用通入 CO 气体的方法清除钢液中气
Under the same conditions, the quality of steel differs according to the amount of impurities it contains, such as phosphorus, sulfur, hydrogen, nitrogen, oxygen and non-metallic inclusions. In alkaline arc furnace steelmaking, when the end of the melting and oxidation of the beginning of dephosphorization, and then in the second half of the oxidation with boiling liquid carbon and hydrogen, nitrogen gas. During the reduction period molten steel removes oxygen, sulfur and non-metallic inclusions. During the oxidation period, the liquid steel boils vigorously to ensure the reduction of the gas content in the steel, but the hydrogen, nitrogen and gas in the liquid steel during the reduction phase can not be removed yet. It has been proposed with the introduction of CO gas to clear the gas in the liquid steel
