Abstract
Способ получения чугуна с вермикулярным графитом, включающий расплавление шихты в электропечи, нагрев в ней расплава чугуна и модифицирование полученного расплава добавками, отличающийся тем, что расплав чугуна нагревают до 1490-1510°C и перед сливом расплава на дно ковша помещают модифицирующую смесь, содержащую комплексную лигатуру ФСМг7 в количестве 0,3-0,5% и 22%-ный силикобарий SIBAR22 в количестве 1,5-2,0% от массы обрабатываемого расплава чугуна. A method of producing cast iron with vermicular graphite, including melting the mixture in an electric furnace, heating the cast iron melt therein and modifying the obtained melt with additives, characterized in that the cast iron melt is heated to 1490-1510 ° C and a modifying mixture containing a complex mixture is placed on the bottom of the ladle FSMg7 ligature in an amount of 0.3-0.5% and 22% SIBAR22 silicobarium in an amount of 1.5-2.0% by weight of the processed cast iron melt.
