Title: Improvements in or relating to the melting of metals and apparatus therefor
IPC: F27D7/06
Filed: 1956-10-15
Abstract: 800,510. Methods of melting metals; alloys. DU PONT DE NEMOURS & CO., E. I. Oct. 15, 1956 [Oct. 20, 1955], No. 31362/56. Class 82(1) A process for melting metal comprises applying radiant heat from a roof 4 to a pile 14 of metal particles in a crucible 8 of metal substantially non-contaminating to the desired molten product and externally cooled, melting a portion of the pile 14 by the radiant heat while introducing additional metal particles at a rate sufficient to maintain the pile 14 above the surface of the melted metal 11, the addition being continued at this rate until the complete charge is introduced, and sustaining the heating to obtain the desired molten product which is then poured through an outlet 13. The process may be modified to be continuous, the spout 13 being used as an overflow. With titanium or titanium alloys the roof 4 is preferably of graphite and is heated by an element 5, an electrical resistor or induction means, e.g. a graphite tube heated by induction or an electric arc enclosable in a graphite tube. The crucible 8 may be machined out, or made by melting and then cooling the metal forming it on the surface of the bowl 3, which is of graphite, molybdenum or other refractory material, while rocking the furnace and externally cooling the bowl 3 below the melting point of the metal. The lower portion of the shell 1 is water or air cooled externally. Additional cooling of the bowl 3 and crucible 8 is effected around the melt level 11 by circulating a fluid through a cooling element 12 below a heat-dam element 10, preferably of porous graphite, protecting the crucible wall above the melt level from heat. The atmosphere in the furnace is inert, and may be of argon, helium or krypton. Metal is charged through an inlet 6, vaporized impurities evolved (magnesium and magnesium chloride) being withdrawn through an outlet 7, if not retained for an inert atmosphere. They can be removed in a stream of inert gas through ports in the crucible walls and condensed for recovery. The metal to be melted may be titanium, zirconium, hafnium or thorium or alloys containing as a major constituent at least one of these metals. Examples of titanium alloys made by this method are the alloys consisting of 94 Tii, 2 Fe, 2 Cr, 2 Mo; 90.9 Ti 1.5 Fe, 1.4 Cr, 1.2 Mo, 5 Al; 90 Ti, 6 Al, 4 V; 92 Ti, 8 Mn; 92 Ti 4 Mn, 4 Al; 92.5 Ti, 5 Al, 2.5 Sn; and 64 Ti, 36 Al; expressed in percentages. U.S.A. Specification 2,085,450 is referred to.

Filed: 1963-08-08
Abstract: 1,010,498. Voltage measurement, electric meters. GENERAL ELECTRIC CO Ltd. Aug. 10,1964 [Aug. 8,1963], No. 31364/63. Headings G1Q and G1U. In an arrangement for measuring unidirectional voltage, the voltage to be measured is applied as an input to the base of a transistor 1 whose emitter and collector are connected via resistors 4 and 6 respectively to ground, the collector also being connected via a meter 2 to a suitable voltage 3. In use the current through the resistor 6 is such that the total current supplied to the meter is substantially directly proportional to the voltage being measured when in excess of a minimum value. The arrangement compensates for the effect of the non linearity of the transistor characteristic in the region of low input voltages. The transistor 1 is a silicon junction transistor, and the resistor 4 is temperature sensitive to compensate for the effect of temperature changes. The arrangement shown will measure negative voltages only, and these may be applied via a range switching arrangement. An arrangement consisting of a resistor 9 and zener diode 8 may be incorporated for calibrating the circuit. To use this arrangement the Zener voltage (which is known) is switched to the transistor input and the potentiometer 6 is then adjusted to produce the correct reading on the meter 2.

Title: Improvements in or relating to the treatment of haematite iron ore for use in the production of iron
Inventor: O'CONNOR HENRY LESLIE
IPC: C21B13/00
Filed: 1961-09-05
Abstract: Prior to smelting, finely divided haematite iron ore is mixed with a bonding medium and then pressed into porous briquettes which withstand the pressures of the smelting furnace, whilst permitting easy access to reducing gases. The preferred bonding agent includes a finely divided calcium compound which forms calcium ferrites with the iron ore.  The ferrites provide additional bonding for the briquettes which dissociate at high temperatures and enable exothermic reduction of ferric oxide to take place.  A specified briquette mix before pressing contains foamed slag, slaked lime, silica sand, haematite and water.ALSO:The invention provides a briquette for charging into a blast furnace in the production of iron, comprising finely ground haematite ore fines and a hard, porous cement matrix distributed evenly throughout the fines and intimately associated therewith, said matrix being composed of hydrated lime, and a foamed blast furnace slag/hydrated lime cementitious product. The free lime content reacts with the ferric oxide of the ore fines in the initial heating period to form calcium ferrites of the typa XCaO.Fe2O3 which preserve the briquette against disintegration until a high temperature in the furnace is reached under which condition there exists the optimum reducing system. Silica sand may be added to the mix from which briquettes are made.
