炼钢吹氧国内普遍使用光管或普通涂耐火泥管,质量较差,不耐用,因此消耗量大,操作工人劳动强度高。此外,由于某些需要,国家每年还要化费大量外汇,进口近千吨的高效吹氧管。目前,经衡水钢管厂中华渗铝分厂与北京钢铁研究总院合作试制,已建成我国第一家高效节能的涂层吹氧管专业生产厂。1988年9月已生产出首批高效吹氧管。在正式投产前的二年中,该种高效吹氧管已先后在首钢特钢厂、莱芜钢铁厂、石家
Oxygen steelmaking commonly used in domestic light pipe or ordinary coated refractory clay pipe, poor quality, not durable, so consumption, operating the high labor intensity. In addition, due to some needs, the state costs a lot of foreign exchange each year and imports nearly 1,000 tons of high-efficiency oxygen lances. At present, Hengshui Steel Plant China Alumina plant and Beijing Iron and Steel Research Institute trial production, has built China’s first energy-efficient coating of professional production plant oxygen pipe. September 1988 has produced the first batch of high efficiency oxygen lance. In the two years before the official commissioning, the high-efficiency oxygen lance has successively set up a series of projects in Shougang Special Steel Plant, Laiwu Steel Plant, Shijia
