摘要： A magnesium treatment process is proposed for the production of a treated iron melt containing less than 100 grams per ton non-metallic inclusions. The treatment reaction is so arranged that the magnesium is introduced into the melt from a chamber at a depth of at least 200 mm below the surface of the melt. Thus, the quantity of vaporized magnesium produces a mixing energy of at least 1,000 W/m.sup.3, which ensures the necessary elimination of non-metallic inclusions. The surface of the molten mass is covered by a non-oxidizing, preferably a reducing atmosphere.

摘要： A method is disclosed for making compacted graphite cast iron of improved strength and hardness while retaining excellent thermal conductivity, low shrinkage, and excellent damping characteristics. A ferrous alloy is melted consisting essentially of, by weight, 3-4% C, 2-3% Si, 0.2-0.7% Mn, 0.25-0.4 Mo, 0.5-3.0% Ni, up to 0.002% sulfur, up to 0.02% phosphorus, and impurities or contaminants up to 1.0%, with the remainder being essentially iron. The melt is subjected to a graphite modifying agent to form compacted graphite upon solidification. The solidified casting is heat treated by austempering and quenching to produce an iron having a matrix of bainite and austenite.

The alloy is a predominately iron alloy having the essential elements by weight of from about 0.1 to about 10% silicon, from about 0.5 to about 4.0% magnesium, from about 0.1 to about 10.0% nickel and optionally from about 0.1 to about 2.0% cerium, and/or other rare earth elements. The alloy may comprise from about 0.1 to about 10.0% silicon, from about 0.5 to about 4.0% magnesium, from about 0.1 to about 10.0% nickel, optionally from about 0.1 to about 2.0% cerium and/or other rare earth elements, from about 0.5 to about 6.5% carbon and the balance iron. Small amounts of calcium, barium or stronium and trace elements customarily found in conventional raw materials used in producing the alloy may also be present. The characteristics of the alloy make it possible to establish a ready supply of treated molten iron in the foundry in holding vessels with a selected chemical composition at a given temperature. It also makes possible semicontinuous and continuous casting of ductile and compacted graphite cast irons.
