Abstract

Moulage en sable. On utilise en tant que matière carbonée une substance anhydre contenant un hydrocarbure et présentant une teneur en carbone de 50-95 %, une teneur en hydrogène supérieure à 6,8 % et une teneur en cendre inférieure à 4,0 % et on mélange à la matière de moulage une quantité de matière minérale fine, poreuse, hydrophile, résistant à la chaleur et présentant des pores ouverts ainsi qu'un coefficient de surface spécifique d'au moins 100 m**2/g. Formation de pièces moulées par moulage en sable à vert.
