平炉碳素镇钢的脱氧操作有许多不同方式,但主要由于近代钢种的化学成分范围规定很严,为了较有把握地控制成品成分不使出格,目前各国大多数工厂都采用着某种形式的炉内脱氧,就是说,将一部分脱氧剂在出钢以前加入炉内.1955年苏联平炉熔炼标准技术规程就是为此而规定了部分炉内脱氧的.但炉内脱氧引起脱氧剂消耗的增大和熔炼时间的延长.如果炼钢工的技术熟练程度足能保证得到规定的化学成分,而且如果缶内脱氧不致使产品质量降低的话,那末将全部脱氧剂加入缶内当然是一个更为合理的方法。近年来缶内脱氧在苏联得到了相当大的重
Although there are many different ways to deoxidize carbon steel in open hearth furnace, it is mainly due to the very strict chemical composition range of modern steels. In order to grasp the composition of finished products more confidently, some factories in most countries adopt a certain form Of the furnace deoxidation, that is to say, part of the deoxidizer added to the furnace before the tapping in 1955 the Soviet Union open smelting standard technical regulations for which the provisions of the part of the furnace deoxidation, but deoxidation furnace deoxidation consumption caused by the increase Large and melting time extension. If the steelworks skilled enough to ensure that the provisions of the chemical composition, and if the internal oxygen deoxidation will not result in reduced product quality, then all the deoxidizer added to the 当 is certainly a more reasonable method. In recent years, Japan’s deoxygenation has received considerable weight
