Abstract

423,612. Casting-machines. INTERNATIONAL DE LAVAUD MANUFACTURING CORPORATION, Ltd., 15, Exchange Place, Jersey City, New Jersey, U.S.A.-(Assignees of Russell, N. F. S., and Langenberg, F. C. ; Edgewater Park, New Jersey, U.S.A.) Sept. 15, 1933, No. 25592. Convention date, Oct. 19, 1932. [Class 83 (i)] Metal-pouring; mould materials.- In casting molten metal helically into a centrifugal metal mould, the rate of cooling is retarded by directing a jet of gas carrying powder towards the mould-surface about to contact with the molten metal. The velocity of the jet should be such as to make the powder adhere without the gas velocity at the mould surface being substantial. The coating should be submerged in less than six seconds or in little more than one revolution of the mould. The jet is preferably directed against the upper surface of the mould and carries enough powder to produce a coating of 0À0003 to 0À001 of an inch in thickness, the figure 0À001 being used for seacoal, 0À0009 for kaolin and talc, 0À0008 for mica, 0À0007 for ferro-manganese, 0À0005 for magnetite and 0À0003 for ferrosilicon and zirconium-manganese-silicon, the thinner coatings being preferable. In the machine shown molten metal is discharged from a stationary runner c into a water-cooled mould D having a spiral movement. The powder is supplied from a container G, as described in Specification 423,614, to the funnel F<4> of a compressed gas injector and is blown along a pipe E, supported on the runner and through a nozzle E<1>, which is constructed as described in Specification 423,613, [Group XXIX], on to that part of the mould which in one revolution will receive the stream of metal. The powder is projected before the stream commences particularly when a socket end D<6> is to be first cast.
