Abstract

The melt is treated in a treatment chamber (4, 5) with an agent (2a) which promotes the formation of spheroidal or vermicular graphite, and is then introduced into a mould cavity (8). The agent (2a) comprises an alloy based on magnesium and/or rare earth metals, and is placed in a recess (2) in the base of the treatment chamber. Above the recess (2) there is arranged a dividing element (3) which acts as a flow resistance and ensures an intense reaction of the melt with the alloy. During the pouring-in process, a pouring gate (7), which communicates the treatment chamber with the mould cavity (8), is closed by means of a plug (6), whereby the melt is dammed-up for a short time before the plug (6) is opened thereby allowing the mould cavity (8) to be filled with treated melt. Thus, the melt is in contact with the agent for a sufficient period until the necessary reaction time has expired and the reaction products separate and a complete blending of the melt is achieved, prior to introduction of the melt into the mould cavity. <IMAGE>
