TEXT � The ob j~n vt of this work was to obtain pr ~mary data to
de':~e~lgp a ~heF~retiv.al method of designing a multi-layer foundry
moil.d so as try arri~~fe at the best mould parameters with control o�
~roaling rates of different parts of a large cast.ang~ This wou]_d
snable retention tune in the mould tq be reduced and castl.ng
structure to be suitably influenced, Moulds with air-ducts have
been proposed by Engineer I~ V� Mit ichev (Ref ~ 1 I.l~Lh No ~ 7, 1q~8
