In treating cast iron with magnesium to produce nodular iron, a capsule of heat-resistant material, closed except for calibrated limited access passages, containing the magnesium, is plunged into a bath of molten metal in a tall vertical ladle while the latter is capped by a hood to contain the violent reaction resulting. An elevating mechanism lowers and raises the hood and capsule and plunges and withdraws the capsule while the hood caps the ladle. The mechanism includes a plunging rod carrying the capsule and means for maintaining the rod in a fixed radial position relative to its axis and for restraining it against the force of the reaction.
