    摘要: A compound cast product is formed in a casting mold (14) having a mold cavity (16) sized and shaped to form the cast product. A plurality of injectors (24) is supported from a bottom side (26) of the casting mold (14). The injectors (24) are in fluid communication with the mold cavity (16) through the bottom side (26) of the casting mold (14). A molten material holder furnace (12) is located beneath the casting mold (14). The holder furnace (12) defines molten material receiving chambers (36) configured to separately contain supplies of two different molten materials (37, 38). The holder furnace (12) is positioned such that the injectors (24) extend downward into the receiving chamber (36). The receiving chamber (36) is separated into at least two different flow circuits (51, 52). A first molten material (37) is received in a first flow circuit (51), and a second molten material (38) is received into a second flow circuit (52). The first and second molten materials (37, 38) are injected into the mold cavity (16) by the injectors (24) acting against the force of gravity. The injectors (24) are positioned such that the first and second molten materials (37, 38) are injected into different areas of the mold cavity (16). The molten materials (37, 38) are allowed to solidify and the resulting compound cast product is removed from the mold cavity (16).

    摘要: A high power non-transferred electric arc heater utilizing interelectrode segments which create a stepped arc chamber intermediate two hollow, substantially cylindrical, axially spaced electrodes. Gas to be heated is admitted upstream of the arc chamber and between adjacent segments. Gas is used to form a cold boundary layer about the expanding core of arc-heater gas. Additional secondary gas inlets adjacent the electrode provide fluid dynamic means for arc positioning on the electrode segments. Gas pressures of less than or in the range of about 1 atmosphere to about 50 atmospheres are used with power levels of about 10 MW being possible. The stepped arc chamber facilitates arc transfer to the downstream electrodes and allows a larger diameter for the arc heated gas while the boundary layer of gas maintaining comparable spacing along the length of the arc-heated gas and the surface of the arc chamber reducing the rate of heat transfer from the arc heated gas to the segments of the arc heater. In an alternate embodiment, field coils are provided around the interelectrode segments and electrodes for the magnetic rotation of the arc within the arc chamber. In a further embodiment, a resistor is interconnected between each interelectrode segment and the electrode segment that is connected as the cathode. These resistors assist in arc initiation and reduce the possibility of strikeover to the interelectrode segments during operation. Multiple electrode segments connected as anode or cathodes can also be provided.

    摘要: A method of preheating a ladle addition to a melt contained in an enclosed or covered ladle without significant loss of melt temperature. A gas stream is heated in a non-transferred arc electric arc heater to a temperature in excess of that of the melt. The ladle addition is introduced into the heated gas stream in the arc heater downstream of the arc heater wherein its temperature is increased to be about equal to or greater than the melt temperature. The heated gas stream and the entrained ladle addition is then introduced into the ladle. As the gas stream impinges on the melt, the ladle addition separates out and combines with the melt with the resulting off-gas being exhausted from the ladle. The off-gas can be recycled to the arc heater for reuse.
