Description

(54) СПОСОБ ПОЛУЧЕНИЯ ЧУГУНА СО СФЕРОИДАЛЬНОЙ ФОРМОЙ ГРАФИТА(54) METHOD FOR OBTAINING AN IRON WITH A SPHEROID FORM OF GRAPHITE

Claims (1)

Формула изобретенияClaim Способ получения чугуна со сфероидальной формой графита при плавке в индукционной печи, заключающийся в расплавлении чугуна, моди45 фицировании его РЗМ или иттрием и его разливке, отличающийс я тем, что, с целью повышения пластических свойств чугуна з^ счет улучшения формы графита, непосред__ ственно после обработки РЗМ или э иттрием, металл подвергают электромагнитному перемешиванию и догреву в течение 25-35 с с удельной мощностью 0,2-1,2 кВт/кг емкости тигля.A method of producing cast iron with a spheroidal form of graphite during melting in an induction furnace, which involves melting cast iron, modifying its rare-earth metals or yttrium and casting it, characterized in that, in order to increase the plastic properties of cast iron, it is possible to improve the shape of graphite immediately after REM processing or e yttrium, metal subjected to electromagnetic stirring and reheating for 25-35 with a power density of 0.2-1.2 kW / kg crucible capacity.
