近年来,由于现代工业的蓬勃发展,制氧技术不断改进,目前制氧设备能力大大增加,氧气成本已大幅度降低,这样为冶金工厂采用氧气冶炼提供了有利的条件,所以各种炼钢操作方法都在研究如何采用氧气冶炼的问题。考虑今后多数矿石要经过选矿才能使用,大部分矿石将成为精矿粉,为了寻求直接炼钢方法,避免烧结或成团等恢复杂工序,氧气固体微粒喷射技术,包括喷嘴结构须加以研究。另外如纯氧喷嘴、烧料氧气烧嘴也要加以试验总结提
In recent years, due to the vigorous development of modern industry, the technology of making oxygen has been continuously improved. At present, the capacity of oxygen making equipment is greatly increased and the cost of oxygen has been greatly reduced. This has provided favorable conditions for oxygen metallurgy in metallurgical factories. Therefore, various steelmaking operations The methods are all about how to use the oxygen smelting problem. Considering that most ore can be used for ore dressing in future, most of ore will become concentrate powder. In order to seek direct steelmaking method and avoid complex process such as sintering or agglomeration, oxygen solid particle jetting technology including nozzle structure should be studied. In addition, such as pure oxygen nozzle, burning oxygen burner to be tested summary
