Abstract

Способ получения высокопрочных чугунов с вермикулярным графитом внутриформенным модифицированием лигатурами системы Fe-Si-РЗМ, отличающийся тем, что в реакционную камеру литниковой системы засыпают необходимую навеску модификатора типа Fe-Si-РЗМ, обеспечивающую начальную концентрацию РЗМ в расплаве 0,075%, затем после сборки литейной формы в ее заливочную чашу для графитизирующего предмодифицирования укладывают кусок ФС75 (ГОСТ 1415-93) массой 0,24-0,46% от металлоемкости формы и производят ее заполнение расплавом чугуна из печи.A method of producing high-strength cast iron with vermicular graphite by intraformal modification by Fe-Si-REM system ligatures, characterized in that the necessary weight of the Fe-Si-REM type modifier is poured into the reaction chamber of the gate system, providing an initial concentration of rare-earth metals in the melt of 0.075%, then after casting assembly molds in its pouring bowl for graphitizing premodification are placed a piece of FS75 (GOST 1415-93) weighing 0.24-0.46% of the mold metal and it is filled with molten iron from the furnace.
