氧气顶吹转炉炼钢具有许多优点,在欧美等一些工业发达国家,转炉炼钢已经非常广泛,在日本平炉几乎完全被转炉所取代,在我国顶吹转炉也日益增多。作为转炉炼钢的重要设备之一——吹氧管提升系统也成为人们研究的重要课题。 在工业发达国家,普遍使用“双氧管双卷扬提升系统”。目前我国引进的转炉设备 Oxygen top-blown converter steelmaking has many advantages. In some industrialized countries such as Europe and the United States, converter steelmaking has been very extensive. In Japan, the hearth furnace is almost completely replaced by the converter, and the top-blown converter is also increasing in our country. As one of the important equipment of converter steelmaking - the oxygen lance lifting system has also become an important issue for people to study. In industrialized countries, the widespread use of “dual-tube double hoist lift system.” At present, China imported converter equipment
