Seetaramaiah, T and Bose, A K and Bhattacharya, P and Rao, P V and Ghose, T K (1983) An insight into the properties of magnesite and magnesite-chromite refrectories for ferro-chrome industry. In: Proceedings of the Seminar on Problems and Prospects of Ferro-Alloy Industry in India, Oct. 24-26, 1983, NML, Jamshedpur.
A few qualities of magnesite and magnesite-chromite bricks and magnesite ramming masses manufactured indi-genously are being used in making ferro-chrome alloy in India. In this paper an attempt has been made for evalu-ating different qualities of magnesite and magnesitech-romite refractories by studying the relevant physico-chemical properties. As the bricks are to withstand severe corrosion and erosion by the molten metal and slag at high temperatures, the mineralogy, microstructure and the modulus of rupture at different temperatures were studied. The hot modulus of rupture values are correlated with the mineralogical compositions of the bricks. A ramming mass based on sea water magnesia has been developed for chute area application and the detailed properties of the same are given.
