Description

(54) СПОСОБ ПОЛУЧЕНИЯ СТАНДАРТНЫХ ОБРАЗЦОВ(54) METHOD FOR OBTAINING STANDARD SAMPLES

ФЕРРОСПЛАВОВ 3 . Полученные слитки, имеюище диаметр 16О мм и высоту 160 мм, измельчают Обработкой на токарных станках. При этом; различие содержани  хрома и углерода во: фракци х измельченного материала состав-;& лает соотвеа-ственно 0,12% и 0,01% т, е.. меньше расхождений, допускаемых методами химического анализа в параллельных пробах. 4526 06 4 Предмет изобретени  Способ получени  стандартных образцов ферросплавов, заключающийс  в выплавке металла, отливке в слитки и измельчении, отличающийс  тем, что, с целью повышени  однородности стандартных образцов, с литки подвергают охлаждению с температуры 1бОО-2ООО°С до 60О-8ОО С при скорости охлаждени  1О-4О град/минFerroalloy 3. The resulting ingots, which have a diameter of 16 mm and a height of 160 mm, are ground by machining on lathes. Wherein; the difference in the content of chromium and carbon in: fractions of the crushed material composition -; & respectively, 0.12% and 0.01% t, e. less than the discrepancies allowed by the methods of chemical analysis in parallel samples. 4526 06 4 Subject of the Invention A method of obtaining standard samples of ferroalloys, which consists in metal smelting, ingot casting and grinding, characterized in that, in order to improve the uniformity of standard samples, it is cooled from temperature to 60 ° C. at a cooling rate of 10 -40 degrees / min
