The traditional technology of iron carbide production exists the problem that the reaction time is too long. The research of adding the additive into the ore of the fluid-bed was carried out in order to find the catalyst of this reaction. It was found out that K2CO3 and CaCl2 can be the catalysts of this reaction. The reacting time and equilibrium data in addition of K2CO3 and CaCl2 were examined and were campared with the contrastive experimental results respectively. The theoretical dynamics analysis also reveals that both K2CO3 and CaCl2 can accelerate the iron carbide forming reaction.
