摘要： A process for the production of nodular cast iron is disclosed. The process comprises adding magnesium to molten iron and then desulphurizing the melt. Next, the melt is after-treated with a neutral gas. The neutral gas which is introduced into the melt may be Ar, N.sub.2, CO.sub.2, or any combination thereof. The after-treatment with the neutral gas scavenges the melt for nonmetallic inclusions. The after-treatment may be performed by blowing the gas into the melt in a known manner using blowing lances or through a porous plug. In a preferred embodiment, the melt is also carburized by treatment with a gaseous hydrocarbon.

摘要： A method of keeping inductor spouts, downgates and outlet casting channels and the like free of deposits during the production of a cast iron melt involves treatment with pure magnesium. Such deposits, which occur as reaction products and block the channels causing considerable maintenance expense, are prevented by the use of pure magnesium. The cast iron melt is flushed free of suspended highly basic reaction products, such as MgO, CaO, Al.sub.2 O.sub.3, FeO and MgS, in a predetermined magnesium treatment of the cast iron melt with pure magnesium by a simultaneous evaporation of magnesium not consumed in the magnesium treatment. By preventing the formation of deposits, the life of the vessel used is increased and maintenance costs are decreased.

摘要： An auxiliary device for use with a permanent mold in casting operations includes a cover plate having an upwardly and a downwardly facing surface. In place on the permanent mold, the downwardly facing surface defines the upper limit of the mold cavity. At least one pipe extends through an opening in the cover plate with its lower end in the plane of the downwardly facing surface of the cover plate. An annular recess located in one of the downwardly facing surface of the cover plate or the lower end of the pipe, encircles the lower end of the pipe radially outwardly from its opening. A breaking core can be incorporated as a part of the lower end of the pipe or it can be formed as a separate member. The pipe can be used only to feed additional molten metal into the mold as the poured metal starts to solidify or it can be used both to pour the molten metal into the mold cavity and then to provide the additional feed as the metal solidifies.
