Abstract
The technology of recycling non-briquetted shavings of Kh18N10T steel by the method of electroslag crucible melting has been developed. Processing was carried out by joint melting of shavings with a consumable metal electrode from scrap metal of the same grade. It is shown that during such melting the metal is refined from extraneous impurities, has a low content of sulfur and gases, metal burning losses do not exceed 2 wt.%, and its chemical composition meets the requirements for Kh18N10T steel. Mechanical properties of metal plates with a thickness of 65...100 mm, obtained by electroslag melting of shavings and scrap of Kh18N10T stainless steel, significantly exceed the requirements of the technical conditions for cast thick-walled products. 6 Ref., 4 Tabl., 6 Fig.
