Abstract
1438693 Casting processes HOWMET CORP 24 Sept 1973 [21 Feb 1973] 46139/75 Divided out of 1438692 Heading B3F In a method of producing directionally solidified castings, a crucible 56 containing the metal 62 is located on top of the mould 32, and the crucible and mould located within a furnace 16 and heated to melt the metal which is then allowed to flow into the mould cavities 46. The crucible 56 is supported on a flat upper surface 52 of the mould 32 and is provided with an opening 60 in its bottom wall, passage of molten metal through the opening normally being prevented by the surface 52. When it is desired to discharge the metal from the crucible 56, the latter is tilted, Fig. 3 (not shown), by means of an arm 68 to move the opening 60 away from the surface 52 to allow metal to flow therethrough into the cavities 46. The shell mould 32 is supported on a chill plate 30 provided with cooling coils 34 and may be raised and lowered by means of a piston rod 40. A flexible baffle 72 may be attached to the top of the mould. The furnace may be provided with induction coils 18 divided into two sections 64 and 66, one section being used to melt the metal 62 and the other section being used to pre-heat the mould 32. Alternatively the chill plate 30 initially is positioned so that only the crucible is within the furnace and is later raised to bring the mould into the heated zone. After the mould has been filled, the chill plate 30 may be lowered gradually to move the mould out of the furnace and bring about directional solidification. The apparatus may include two housings 10 and 12, Fig. 1 (not shown), defining upper and lower chambers respectively to permit the process to be carried out in a vacuum or inert atmosphere. The furnace is located in the upper chamber and the mould and crucible may be lowered into the lower chamber through cooling coils 38 and a valve 44. To obtain a very flat upper surface 52 on the shell mould, the wax pattern employed in the production of the mould may be provided with a metal disc.
