碳化铁

It is shown that the formation process of iron carbide converted from hematite using H〓-CH〓 mixtures consists of several steps: reduction of iron ore, cracking of methane, and carburization of metallic iron.

试验发现赤铁矿与H〓-CH〓气反应制备碳化铁的过程是分步完成的，第一步是赤铁矿的还原，第二步是甲烷的裂解，然后是金属铁的碳化。

The experimental results show that high conversion ratio of iron carbide could be obtained using reducing gas with suitable ratio of H〓/CO at 973K and 1073K.

试验结果表明在973K、1073K下反应时，选择合适H〓／CO比例的反应气体能得到较高碳化铁转化率，而1173K下未能得到。

The reason why no iron carbide was detected in the initial stage of the reaction is that carbon formed from methane cracking was consumed by reduction products H〓O.

对反应过程试样及进出口气体成分分析发现，反应前期无碳化铁生成的原因是甲烷裂解析出碳与还原反应产物H〓O反应而消耗。

With short flow route process steelmaking swiftly arising and shortage of high quality scraps, iron carbide has been concerned widely as its unique phisics and chemistry feature as well as production conditions, and as an excellent replacement of scrap.

由于炼钢短流程工艺的迅速兴起，优质废钢短缺，碳化铁可作为优质的废钢代用品，以其特有的物理性质、化学性质以及生产条件而受到广泛的关注。
