摘要
含碳球团技术是有效利用低价的高结晶水铁矿、实现高炉降低焦比和燃料比的技术途径之一。介绍了日本提高含碳球团冶金性能技术的研究现状,包括提高含碳球团反应性和还原性的研究进展。发现减小焦炭或者煤粉粒度、使用生物质炭、设计新型球团结构可以提高含碳球团的反应性,使用高结晶水铁矿粉可以提高含碳球团的还原性。此外,还介绍了含碳球团在高炉中的应用效果。
Carbon-containing pellet technology is one of useful ways to utilize low price iron ores with high crystal water and to realize low coke rate and low fuel rate operation of blast furnace. The current research situation of improving carbon-containing pellet metallurgical properties in Japan is introduced, which includes research development on increasing reactivity and reducibility of carbon-containing pellets. It is discovered that, decreasing the size of coke and pulverized coal, adding biomass charcoal and designing new type of pellet structure can improve the reactivity of carbon-containing pellets, and using iron ore fines with high crystal water can increase the reducibility of carbon-containing pellets. In addition, the application effect of carbon- containing pellets in the blast furnace is also introduced.
