    摘要： The monolithic graphite electrode has a first end face including a socket and a second end face located at an opposed end face of the electrode body including a threaded tang, wherein a main body has a length of more than 3175 mm. Another embodiment disclosed herein includes an electrode column comprising a plurality of monolithic graphite electrodes. The column has a length of more than 3175 mm of electrode per joint. A further embodiment discussed herein is the practice of increasing the length of the electrode to minimize the occurrence of an electrode joint in the electrode column for a given length. This practice will improve efficiencies for both electrode manufacturers as well as electric arc furnace operators.

    摘要： An induction furnace capable of operation at temperatures of over 3100°C has a cooling assembly (60), which is selectively mounted to an upper end of the furnace wall (76). The cooling assembly includes a dome (62), which is actively cooled by cooling water coils (68). During the cool­down portion of a furnace run, cooling initially proceeds naturally, by conduction of heat away from the hot zone through a furnace insulation layer (58). Once the temperature within the furnace hot zone (20) reaches about 1500°C, a lifting mechanism (80), mounted to the dome, raises a cap (16) of the furnace slightly, allowing hot gases from the hot zone to mix with cooler gas in the dome. This speeds up cooling of the hot zone, reducing cool-down times significantly, without the need for encumbering the furnace itself with valves or other complex cooling mechanisms which have to be replaced periodically. The life of a graphite furnace susceptor (10) at the high operating temperature is increased by surrounding the susceptor with a barrier layer (40) of flexible graphite, which inhibits evaporation of the graphite. Additionally, witness disks (154), placed within the susceptor, provide an accurate temperature profile of the hot zone.

    摘要： There is disclosed a display device comprising a) a liquid crystal display device which comprises a plurality of heat sources; and b) a heat spreader (10) which comprises at least one sheet of compressed particles of exfoliated graphite (5) having two major surfaces (12 and 14), the heat spreader having a surface area greater than the surface area of that part of the back surface of the display device where a localized region of higher temperature is generated, wherein substantially all of one of the major surfaces of the heat spreader is in thermal contact with the liquid crystal display device and further wherein the heat spreader itself reduces the temperature difference between locations on the display device.

    摘要： The present invention concerns monolithic graphite electrodes of increased length. The electrode has a main body having a length of more than 3050 mm. Another embodiment disclosed herein includes an electrode column comprising a plurality of such monolithic graphite electrodes. The column has a length of more than 3050 mm of electrode per joint. A further embodiment discussed herein is the practice of increasing the length of the electrode to minimize the occurrence of an electrode joint in the electrode column for a given length. This practice will improve efficiencies for both electrode manufacturers as well as electric arc furnace operators.
