Abstract

746,996. Making magnesium anodes by extrusion. DOW CHEMICAL CO. May 4, 1954, No. 13006/54. Classes 83 (2) and 83 (4). [Also in Group XVIII] A cored magnesium anode rod is made by extruding magnesium or magnesium base alloy through a die orifice 15 around a steel wire 5 coated with aluminium or aluminium alloy. A magnesium billet is forced from a container 7 by a ram 8 through holes 12 into an annular pressure chamber 13 and is extruded therefrom around the wire 5 fed through a passage 20 in a die carrier 10, and nozzle 18. By the provision of differing tapers of the nozzle surface and the conical approach surface 16 of the die 14 and by terminating the tip 22 of the nozzle slightly before the end of the surface 16, relative motion between the wire and the magnesium occurs just before entry into the die. orifice 15 and this assists in creating an effective bond between the wire and the extruded magnesium. The dimensions of a typical anode, made from magnesium base alloy, and its core wire are given. The anode is for use in minimizing corrosion in domestic water heater tanks.
