Study of Pinholes Genesis in Iron Castings

Popis výsledku v původním jazyce

The study concerns the formation of pinholes in castings formed by reaction between a green foundry mould and lamellar graphite cast iron. Experiments were done on castings of stepped bars moulded in green bentonite mixtures with s graduated moisture andwith use of two types of carbonaceous matters. Metal was melted in a 100 kg induction furnace from the same charge. Inoculation was done in a ladle after pouring out from the furnace.Aluminium was dosed in the ladle in some cases and the inoculator kindwas changed too. Results: Pinholes were present on castings as small flat pits; on horizontal surfaces sooner singly, on casting edges in clusters. The formation of pinholes wasn?t caused by high moisture of moulds but the defect was sensitive to aluminium content in metal. In castings with high aluminium content > 0.01 % the pinholes were present in great numbers, and namely both under low, and also high moistures of moulding mixtures. In melts with low content of Al < 0.01 % the pinho
