Abstract

Cast iron melts are inoculated by disposing in the path of the molten metal during pouring in a position above the mould an element moulded from the inoculating material, so that it makes contact with the flowing metal. Castings of different shape and size can be made from the same mass of melt before loss of the matrix modification, which was obtd. by addn. of small amts. of additives.
