Abstract

Išradimas susijęs su terminiu metalų ir jo gaminių apdirbimu.@Siekiant optimalaus bėgio ar bėgio galvutei aušinimo greičio ir norint išvengti bėgio sienelės užgrūdinimo, terminiu būdu, panardinus į aušinimo skystį su sintetiniais aušinimo skysčio priedais, apdirbamas bėgis ir ypač bėgio galvutė, pradedant nuo jų paviršiaus temperatūros nuo 720 °C ir tęsiant tol, kol jų paviršiaus temperatūra, ištraukus iš aušinimo skysčio, bus intervale nuo 450 iki 550 °C, o temperatūra visame skerspjūvyje dar neišsilyginusi.
