METHOD OF PREPARATION OF SAMPLES OF METALLURGICAL SLAGS FOR CHEMICAL ANALYSIS Russian patent published in 2005 - IPC

FIELD: ferrous metallurgy; preparation of samples of metallurgical slags for chemical analysis.

SUBSTANCE: proposed method includes grinding the slag sample, mixing and reducing sample mass which are performed at seven stages. First stage includes grinding the slag sample. Second, third, fourth, sixth and seventh stages includes grinding, mixing and reducing sample mass to required magnitude. Fifth stage includes drying and cooling the sample. Prior to first, second, third and fourth stages, metallic inclusions are manually removed. At fourth, sixth and seventh stages metallic inclusions are removed by screening in sieves between grinding operations.

EFFECT: improved quality of slag sample; enhanced accuracy of chemical analysis; reduction of time required for performing chemical analysis due to proper grinding of slag sample.
