钢铁企业的烧结、炼铁、炼钢等工艺环节产生着大量含铁粉尘,严重污染着环境,也浪费着宝贵的钢铁资源。在进口铁矿石价格长期居高不下、国际国内市场竞争日趋激烈等等残酷现实面前,急需充分回收、利用这些含铁废弃物。就目前国内外钢铁企业纷纷投资建设的转底炉直接还原工艺进行简述,重点对摆头胶带机的摆动机构进行适应性技术改进。
Iron and steel enterprises in the sintering, ironmaking, steelmaking and other processes produce a lot of iron-bearing dust, seriously pollutes the environment, but also a waste of valuable steel resources. In the face of cruel reality such as the long-term high price of imported iron ore and increasing competition in the international and domestic markets, it is in urgent need of full recovery and utilization of these iron-containing wastes. At present, domestic and foreign steel enterprises have invested in the construction of the rotary hearth furnace direct reduction process is briefly described, focusing on the swinging mechanism of swing head belt adapters to improve the technology.
