Conclusions

An investigation into kinetics of reduction-decarburization annealing in industrial reduction furnaces employing a converted gas (CO2/CO = 0.41 and 7–9% H2O) countercurrent has demonstrated that, to obtain satisfactory and stable results in a short time of annealing at 900–1000°C with an atomized cast iron powder of O/C ratio 1.9–2.2, the heating of the powder to the required annealing temperature should be performed at a rate not exceeding 9 deg C/min.
