Abstract

1,096,108. Electric resistance furnaces. HOWMET CORPORATION. Sept. 13, 1965 [Dec. 4, 1964], No. 38998/65. Heading H5H. A resistance melting furnace comprises a cylindrical refractory crucible 10 in which is suspended a horizontal cylindrical graphite resistance element 13 comprising a plurality of intermediate portions 66 in face-to-face contact between end portions 64, 65. Each portion 66 has conical, cylindrical or spherical shaped male and female mating ends, Figs. 2, 3, 4, 5 (not shown). The crucible, enclosed by insulating material 14 within a metal shell 15, is mounted on supports 11, 12 for rotation about a horizontal axis. The electrode 13 is carried on supports (40) and extends through the crucible and supports 11, 12 in alignment with the axis of rotation, an 0-ring (41), Fig. 2, sealing the interior of the crucible from the atmosphere. The supports (40) are slidably mounted on rods 58, 59 on the main support structure 20, and springs 60, 61 force the supports 40 together holding the portions of the element together in compression. An axial bore extends through the element and its supports to facilitate assembly using a mandrel. The supports 40 and the 0-ring are water cooled. Material to be melted passes to and from the crucible through a conduit (17) and A, N 2 and CO is supplied through an inlet 19.
