浅析国内球团矿及提高其冶金性能的研究现状

Analysis of Domestic Pellet and Research Status of Improving its Metallurgical Properties

文中简单地详细介绍了国内一些大型球团铁矿的生产球团加工理论和生产技术上的研究进展,其中主要包括了大型球团的铁矿产量、生产工艺、球团生产原材料选择、新型添加剂的加入、MgO对其影响。在焙烧球团矿之前对球团进行正确的预处理,采用向球团中添加新型黏结剂或者添加剂均会增加球团矿的冶金性能。能够开发应用对球团矿有利无弊且符合环保要求的黏结剂将是今后研究的一个方向。球团矿的发展有利于提高高炉炼铁节能和环保两大方面,经过广大科研工作者的努力研究,如何研究更加优质的球团矿将成为今后造块的主题,优质球团矿将会在不久的将来广泛普及。

In this paper,the research progress of pellet processing theory and production technology of some large-scale iron ore pellets in China is briefly introduced in detail,including the iron ore output of large-scale pellets,production process,selection of raw materials for pellet production,addition of new additives and influence of MgO on them.The proper pretreatment of pellets before roasting and the addition of new binders or additives will increase the metallurgical properties of pellets.It will be a research direction in the future to develop and apply binders,which are beneficial to pellet and meet the requirements of environmental protection.The development of pellet is beneficial to improve the energy saving and environmental protection of blast furnace ironmaking.Through the efforts of the majority of scientific research workers,how to study more high-quality pellet will become the theme of future briquetting and high-quality pellet will be widely popularized in the near future.
