MATERIALS FOR STEEL DIFFUSION DEOXIDATION
Аннотация
The work carried out tests and implementation of a diffusion alumi-na-containing deoxidizer (RDA) for steels produced by LTD Metallurg SRD RAC according to TS 0826-003-47647304-2001.
The deoxidizer was used instead of traditional mixtures consisting of lime, FS65 ferrosilicon and fluorspar. RDA is a mixture of powders of carbon-, silicon- and aluminum-containing materials produced by physi-cochemical methods and had high dispersion.
With the use of RDA, 2,704.82 tons of billets were smelted, treated and poured. Carbonaceous material and FS65 were excluded from the diffusion deoxidation process. Fluorspar consumption was reduced by 50%. The average consumption of RDA for this period was 0.41 kg / t (for comparison: the consumption of FS65 for diffusion deoxidation is 1 kg / t).
