    摘要： A low elemental silicon source of ferrophosphorus used to increase the phosphorus content of molten iron, steel and their alloys is prepared by pulverizing ferrophosphorus having an elemental silicon content in excess of 1 percent by weight to enable it to pass a 3/8-inch sieve. Next, phosphoric acid is mixed with the ferrophosphorus. The phosphoric acid oxides substantially all of the elemental silicon to silica. After oxidation, the resulting composition is dried and formed into the desired size and shape for ease of handling during iron and steel making processes.

    摘要： The invention relates to a method of rapidly decarburizing a high-carbon ro-alloy with oxygen for avoiding an undesirable oxidation of the principal alloying elements, especially chromium or manganese, comprising blowing an oxidizing gas under the surface of a bath of molten ferro-alloy from one or more gas-jacketed nozzles in an amount ranging between substantially 3 and 15 m.sup.3 S.T.P. per metric ton of ferro-alloy with reduction of the carbon content of the ferro-alloy at a rate of about 0.2% to 1%. Comminuted solids, especially particles of oxides of alkaline-earth metals such as powdered lime, may be admixed with the oxidizing gas to prevent the ejection of molten metal from the bath.

    摘要： A continuous one-stage process for producing silicon-containing ferro alloys consists in making up of a charge comprising quartzite and a briquetted mixture of an ore carrying an alloying element of the alloy to be produced with a carbonaceous reducing agent comprising a carbon content 1.03 to 1.25 times as low as that sufficient for the reduction of all the elements in the charge, and 2 to 15 times as high as that sufficient for the reduction of the alloying element and subsequent smelting the resultant charge in a smelting furnace.

    摘要： Ferrophosphorus is heated in admixture and excess aluminum to convert the phosphorus therein to aluminum phosphide. The aluminum phosphide is hydrolyzed and an alloy comprising the nonphosphorus constituents of the ferrophosphorus and unreacted aluminum is separated from the hydrolysis products. The alloy of non-phosphorus constituents and aluminum is useful in the metallurgical industry and the phosphine obtained during the hydrolysis reaction has well-known utility as a chemical intermediate, for example, in preparing gasoline additives such as tributyl phosphine.
