Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania żeliwa wysokojakościowego z zastosowaniem form piaskowych, obejmujący proces sferoidyzacji ciekłego żeliwa przy udziale znanych zapraw i modyfikatorów, według wynalazku który charakteryzuje się tym, że sferoidyzację ciekłego żeliwa prowadzi się początkowo w kadzi odlewniczej, do której podaje się od 10% - 25% całkowitej ilości zaprawy koniecznej do procesu sferoidyzacji, a następnie zbiera się żużel i tak oczyszczone płynne żeliwo podaje się do układu wlewowego form odlewniczych piaskowych, do których to form podaje się pozostałą część zaprawy koniecznej do procesu sferoidyzacji.The subject of the application is a method for producing high-quality cast iron using sand molds, comprising the process of spheroidization of liquid cast iron with the participation of known masterbatches and modifiers, according to the invention, which is characterized in that the spheroidization of liquid cast iron is initially carried out in a casting ladle, to which 10% - 25% of the total amount of masterbatch necessary for the spheroidization process is fed, and then the slag is collected and the liquid cast iron thus purified is fed to the gating system of sand casting molds, to which the remaining part of the masterbatch necessary for the spheroidization process is fed.
