摘要: The discussed system is of outstanding importance for steelmaking and also in cement manufacture. Since lime (CaO) one the most important additives steel plant refractions, reactions formed compounds iron with are particular interest. These processes influence reduction characteristics as well slag formation blast furnace. A huge number studies have been done especially region where equilibrium various oxides system. First investigations start thirties Germany (Schrenck Martin et al. [1929Sch, 1934Mar, 1937Sch] Italy (Cirilli Burdese [1947Cir, 1952Cir, 1952Bur, 1954Bur, 1960Bur]. [1961Tur] calculated activities oxygen Ca-Fe-O melts from available experimental data developed a sequence theoretical considerations, which favored by several authors. Very work was presented Schurmann his group [1973Sch, 1976Sch1, 1976Sch2, 1976Sch3, 1976Sch4, 1993Sch]. Some reported at higher content no final equilibria between oxides. In potential, solid phases, not measured or given all. Reviews phase diagrams [1943Whi], [1965Mua], [1976Sch4] [1989Rag]. Calphad type assessment performed [1989Sel, 1990Hil, 1996Sel, 2001Fri]. An independent [1993Wu]. All calculations reproduce only partly. Therefore [1989Rag] favored. works this listed Table 1.
