摘 要: 重点研究原料水分、粒度和加热时间对热压含碳球团强度的影响,并对影响机理进行分析。实验结果表明:原料水分对热压含碳球团的强度影响较小;原料粒度包括煤粒度和矿粒度对热压含碳球团的强度影响高度显著,煤粒度0.180 mm、矿粒度0.450 mm时热压含碳球团的强度达到270 kg/个;加热时间对热压含碳球团的强度影响高度显著,在此次实验条件下加热时间取30 min为最佳。
关 键 词: 粉末冶金;热压含碳球团;水分;粒度;加热时间;强度

Abstract: This paper focuses on the impact of moisture content, particle size and heating time of raw material on the strength of the carbon composite iron ore hot briquette, and explores the mechanism of pellet strength. The experimental results show that moisture content of raw material has little influence on the pellet strength. Coal and ore particle sizes have a great influence on the pellet strength. When the coal size is 0.180 mm and the mine size is 0.450 mm, the pellet strength is 270 kg/piece. Heating time has a great influence on the pellet strength, within this experimental condition, the best heating time is 30 min.
Key words: powder metallurgy; carbon composite iron ore hot briquette; moisture content; particle size; heating time; strength
