Preparation of iron and steel powders from high-carbon melts by air atomization

Conclusions

• 1. The intensity of oxidation of impurities and the principal component in a high-carbon Fe-C melt in the course of dynamic reaction with an air stream depends on the velocity and temperature of the latter and on the extent to which the melt has been superheated above the liquidus.

• 2. “Decementation” of the starting dispersed Fe- C alloy at high temperatures (> 1100°C) increases the P_CO :$P_{CO_2 }$ partial-pressure ratio and raises the carbon content of the final product.
