Abstract
765,423. Making additions to iron and steel. MOND NICKEL CO., Ltd. March 2, 1955 [March 6, 1954; Jan. 27, 1955], No. 6191/55. Classes 72 and 82(1) An addition agent of lower boiling point than iron is introduced into molten iron or steel by placing the addition agent and a container of the molten metal separately into a pressure vessel, introducing a compressed gas into the pressure vessel to raise the pressure to a value at least equal to the vapour pressure of the addition element at ' the temperature within the vessel and mixing the addition element and the molten metal with vigorous stirring whilst maintaining the pressures. More than one addition element may be added, the pressure then being kept above that of the addition element having the highest vapour pressure. In the apparatus for treating iron with magnesium shown, a ladle 48 containing the iron is placed within the pressure vessel 6, the lid 11 of the vessel mounted in a framework 12 is swung into position and the vessel is raised by the hydraulic ram 4 to force it against the lid. Air is expelled from the pressure vessel through a cock 41 by argon from a cylinder 32, the cock 41 then being closed and the pressure allowed to build up to the desired value. An openwork container 20 holding the magnesium is then lowered into and reciprocated in the iron by a compressed air piston 10. When the mixing is complete, a valve 31 in the argon supply line is closed and the cock 41 opened to allow the argon in the pressure vessel to pass into a low-pressure gas reservoir 44. The cock 41 is then closed again and the pressure vessel opened and the ladle removed. The argon in the reservoir 44 may be compressed by a compressor 38 for re-use. In other forms of apparatus described the magnesium may be added to the iron by (1) lowering an openwork container into the iron and stirring the melt by induction, (2) lowering the container into the iron and rotating it to cause stirring. (3) pouring the iron from an upper ladle on to the magnesium in a lower ladle, or (4) supporting the magnesium on a disc which is then reciprocated in the iron. The upper part of the pressure vessel may be lifted by a crane and lowered in turn on to a number of bottom parts and the vessel may be pressurized by compressed air.
