  • Nitriding of ilmenite and high-grade T slag fines

    2011. 4. 13.· ilmenite and chloride grade slag fines to TiN in order to be able to estimate the size of an industrial tunnel kiln that would be required for the process. The main reason for considering a tunnel kiln (or rotary hearth furnace) rather than rotary kilns or fluidized beds is the endothermicity of the reaction and highly reducing conditions required.
