| Abstract: | Carbon composite iron ore hot briquette(CCB) is a new type of iron-making raw materials,which is made through hot briquetting by binding coal and iron ore fine.The reducibility is one of major metallurgical properties for iron-making burdens.The reacting atmosphere and temperature effecting on the reducibility of CCB have been studied through the experiments of reduction weight loss.The experimental results show that the whole reduction process of CCB could be divided into two stages.The reduction rate duri... |
