METHOD FOR PRODUCTION OF STANDARD SMAPLE OF STEEL, CAST IRON OR ALLOY COMPOSITION, WHICH ARE MICROALLOYED WITH VOLATILE METALS (VERSIONS), STANDARD SAMPLE OF STEEL, CAST IRON OR ALLOY COMPOSITION, WHICH ARE MICROALLOYED WITH VOLATILE METALS, WITH CERTIFIED CONTENT OF ONE OR MORE METALS, SELECTED FROM FOLLOWING GROUP, INCLUDING LEAD, BISMUTH, ANTIMONY, TELLURIUM, ZINC, TIN, COPPER, ALUMINIUM

摘要

FIELD: metallurgy.;SUBSTANCE: invention is related to ferrous metallurgy, in particular to technology for production of standard sample of steels, cast irons or alloys composition with certified content of one or more volatile chemical elements. Method includes preparation of steel, cast iron or alloy melt and its microalloying with volatile metals, moulding of cast and/or deformed section, production of sample for chemical and/or physical methods of analysis and certification of controlled elements. Microalloying of melt is done with melt on the basis of (tin or copper or aluminium), which contains one or several volatile metals, selected from group, including lead, bismuth, antimony, tellurium, zinc, with the following ratio of elements, wt %: lead 0.15-8.0, bismuth 0.15-8.0, antimony 0.35-8.0, tellurium 0.15-8.0, zinc 0.15-8.0, (tin or copper or aluminium) the rest.;EFFECT: invention provides for required chemical homogeneity of standard sample with previously set low concentrations of certified volatile elements due to their insertion into metal melt in the form of alloy, and practically excludes their evaporation and reduces emission of volatile elements vapors into working zone.;4 cl, 6 tbl
