雾化制粉原料中低碳铬铁的制备研究进展
|
摘要
根据含碳量的不同,铬铁主要分为高碳铬铁(含碳4.00%～8.00%)、中碳铬铁(含碳0.50%～4.00%)、低碳铬铁(含碳0.15%～0.50%)(均为质量分数,下同),其中中低碳铬铁是雾化制粉的重要原料。主要综述了目前国内外中低碳铬铁制备的发展现状,分析了传统制备方法的优缺点,重点介绍了直接还原法和微波加热技术联合制备中低碳铬铁,以及制备过程中的一些影响因素,如还原温度、还原时间、还原剂、碱度、粒度以及其他的一些影响因素对金属化率及升温速率的影响,并展望了中低碳铬铁制备的发展方向与研究前景。
According to the different carbon content,ferrochrome is mainly divided into high-carbon ferrochrome(containing 4.00%-8.00% carbon),medium-carbon ferrochrome(containing 0.50%-4.00% carbon)and low-carbon ferrochrome(containing 0.15%-0.50% carbon)(all in mass percent). Among them,medium and low carbon ferrochrome are important raw materials for atomized powder. The development status of medium and low carbon ferrochrome preparation at home and abroad were mainly summarized,the advantages and disadvantages of traditional preparation methods were analyzed,and the preparation of medium and low carbon ferrochrome by direct reduction and microwave heating technology,as well as some influencing factors in the preparation process,such as reduction temperature,reduction time,reducing agent,alkalinity,particle size and other influencing factors on metallization rate and heating rate were mainly introduced. The development direction and research prospect of medium and low carbon ferrochrome preparation were also prospected.
