Procedure for the removal of excess oxygen (refining process) from steel melts. The oxygen content is to be decreased that far, that solidification takes place without blistering. Deoxidization is executed in the ladle or in the electric arc furnace. There is a differentiation between deoxidization via the gas phase, precipitation deoxidization (by addition of elements, whose oxygen affinity is larger than that of iron; this includes Mg, Mn, Si, AI, C, Ca) and diffusion deoxidization as well as their combination.
