Definitions

  • Our invention relates to the Aston process of making wrought iron, such, for example, as set forth in several United States patents of James Aston, such as No. 1,370,507, granted March 8, 1920, for method of making wrought iron pipe; No. 1,412,823, granted April 18, 1922, for method of making wrought iron; and No. 1,469,373 granted October 2, 1923, for manufacture of wrought 1o 11011.
  • the depth of slag at the start of t e pouring operation should be not less than 18 or 20 inches, and is preferably 3 or 4 feet.
  • the pouring spout or nozzle of the receptacle containing the molten product of the steel-making operation should be more than '6 feet above the level of the slag, and is preferably 10 to 12 feet abovethat level.
  • Figure 1 is a plan view showing one form of crl'eceptacle for carrying out our invention.
  • Figures 2 and 3 are vertical cross-sections of the same on the lines IIII and III-III,
  • 2 is an iron or steel shell wh1ch may be either cast or of wrought material. converges downwardly to a slight extent on two sides cm and to a greater extent on the sides 66.
  • the sides aa are preferably cast with hollow projections 3, 3 forming parts of trunnion pads and lifting lugs.
  • the casting is preferably provided with an inwardly projecting flange 4 and is lined with a refractory material, such as firebrick 5, covering the bottom and sides.
  • the internal dimensions of the lined vessel are about as follows: at the bottom, 3 feet between thesides bb and 4 feet between the sides aa, with a depth of about 4% to 5 feet.
  • the liquid slag is cured into this receptacle to a depth of pre erably 3 to 4 feet, and the liquid steel is then poured in from a height of 6 to 12 feet, and preferably about 10 to 12 feet.
  • the pour is regulated so that the pouring rate isnot faster than 1 tons per minute and the volume of slag is more than four times the volume of metal poured into said slag.
  • the vessel shown is, of course, merely an example.
  • the step consisting of pouring metal from a steelforming operation into and through a bath of puddle slag of a depth greater than 18 inches.
  • the step consisting of pouring metal from a steelforming operation into and through a bath gf puddle slag of a depth of about 3 to 4 eet.
  • the step consisting of pouring metal into a slag bath from a height of not less than 6 feet above the slag level through a bath of puddle slag of a depth greater than eighteen inches.
  • the step consisting of pouring metal into a slag bath from a height of 10 to '12 feet above the slag level through a bath of puddle slag of a depth greater than eighteen inches.
  • the step consisting of pouring the molten product of a steel-making process into a slag bath in a stream at a rate not faster than one ton in 1 minutes.
  • the step consisting of pouring a stream of the molten product of a steel-making process into a slag both at a rate of about 2 minutes per ton.
  • the step consisting of pouring into a bath of puddle slag the product of a steel-making operation to an amount not more than onefourth the volume of the slag.
  • the step consisting of pouring steel into a bath of puddle slag of a depth of more than 18 inches, and restricting the volume of steel poured into less than one-fourth the volume of the slag.
  • the step consisting of pouring into the bath of puddle slag the product of a steel-making process at a rate not greater than one ton in 1 minutes and to a total amount less than our hands.
