eaf and ladle furnace roof<\/h1>\n\n\n\n

This is a furnace that heats charged material by means of an electric arc. The roof of the arc furnace is one of the most affected portion as it is subjected to all kind of stresses, e.g. thermal, chemical and mechanical. The roof is exposed to very high temperature often exceeding 1700\u00b0C. It is also exposed to corrosive action of slag and metal oxides, specially iron oxide fumes which is deleterious towards the refractories. Since the design is also complicated because of the openings of the electrodes etc. it is subjected to considerable mechanical stresses.<\/p>\n\n\n\n
