FIELD: metallurgy.
SUBSTANCE: carburiser contains, wt %: silicon carbide 5-20, heat-treated coke is the rest. High and stable recovery rate of carbon by liquid metal is achieved owing to heat evolution from interaction of silicon carbide and high free surface energy of dispersed components of proposed carburiser. Carburiser corresponds to carbon-bearing materials, manufactured at high temperatures.
EFFECT: extra low content of nitrogen.
