Abstract

Przedmiotem zgłoszenia jest sposób pionowego zalewania form wielkogabarytowych masywnych odlewów płytowych. Sposób polega na tym, że wykonuje się dwie przystające do siebie części formy, każdą z nich w niezależnej skrzyni formierskiej ustawionej na płycie podmodelowej z umieszczonym w niej modelem wraz z elementami centrującymi, wyposażonej w zamocowany w jej wnętrzu co najmniej jeden aktywny segment chłodzący o kształcie dopasowanym do odlewu i znanej pojemności cieplnej, przy czym w trakcie zasypywania modelu formuje się układ wlewowy i rozpoczyna proces wibracyjnego zagęszczania masy formierskiej wprowadzając cały układ w drgania o częstotliwości okołorezonansowej. Po związaniu masy formierskiej zespala się ze sobą obie skrzynie formierskie, a następnie podnosi się do pozycji pionowej i instaluje się zbiornik zalewowy na górnej ścianie skrzyni i podpina przewody łączące kolektor z aktywnymi segmentami chłodzącymi, po czym zalewa się formę ciekłym metalem i rozpoczyna się proces chłodzenia odlewu mgłą wodną.The subject of the application is a method of vertical pouring of large-size forms of massive plate castings. The method consists in making two adjacent mold parts, each of them in an independent molding box placed on a sub-model plate with a model placed in it together with centering elements, equipped with at least one active cooling segment in the shape matched to the casting and the known heat capacity, while the gating system is formed during filling the model and the process of vibratory compaction of the molding sand begins, introducing the entire system into vibrations at a resonant frequency. After the molding sand is bound, both molding boxes are joined together, then raised to a vertical position and the flooding tank is installed on the top wall of the box and the pipes connecting the collector with active cooling segments are connected, then the mold is poured with liquid metal and the cooling process begins casting with water mist.
