Abstract

In order to obtain the solubility of carbon in vanadium-bearing hot metal, graphite powder is used for the carburization experiments. The other kinds of carburizers, namely low nitrogen carburizer, anthracite and coke are used for carburization of vanadium-bearing hot metal weighing 500 g at temperature of 1450, 1500 and 1550 °C respectively. Carbon increments of low nitrogen carburizer, anthracite and coke fall in descending order. It was found by comprehensive analysis that anthracite is the most cost-effective carburizer among three carburizers. Magnitude of apparent rate constant of carburization reactions is 10⁻⁴ s⁻¹. It is found that the carburization rate increase with temperature.
