Abstract

Using thermodynamic calculation methods, by chemical analysis in the refining end and ingot, combined with the initial composition of the charge and use of, the effect of furnace lining on carbon deoxidization reaction in the vacuum induction melting process of one kind of super-alloy for 700℃ ultra-supercritical boilers were researched. The results show that: under our experimental conditions, the effect of using Al2O3 crucible on carbon deoxidization reaction can be neglected, and ultra-pure melting can be achieved; inferred by the calculation results, the original charge contains a small amount of Al, play a useful role to prevent C and Al2O3 crucible reaction, and inhibition of oxygen aeration in the liquid metal.
