ИНДУКЦИОННАЯ ПЕЧЬ ДЛЯ РАБОТЫ ПРИ ВЫСОКИХ ТЕМПЕРАТУРАХ

Изобретение относится к металлургии, а именно к индукционным печам, работающим при температурах около 3000°С и выше, которые используют при графитизации волокон пека, а также для других высокотемпературных процессов, например галогенная очистка графитовых материалов для удаления металлических примесей. Печь содержит емкость, образующую внутреннюю камеру для расположения изделий для обработки, с токоприемником, индукционную катушку, которая индуцирует ток в токоприемнике для его нагрева, водоохлаждаемый свод. Когда температура внутри горячей зоны печи достигает примерно 1500°С, подъемный механизм, смонтированный на своде, поднимает крышку печи, давая возможность горячим газам из горячей зоны смешиваться с более холодным газом в своде. Это ускоряет охлаждение горячей зоны, значительно уменьшает периоды охлаждения без необходимости загромождать саму печь клапанами или другими сложными охлаждающими механизмами, которые должны периодически заменяться. Долговечность графитового токоприемника ...

Improvements in and relating to the manufacture of linings of furnaces

... 303,574. Campbell, D. F., and Electric Furnace Co., Ltd. April 16, 1928. Heating by electricity. -Furnace linings are formed in situ by placing refractory material A around a plug C of electric conducting material and heating the plug by currents induced from a coil D which surrounds the material and is traversed by alternating electric currents, preferably of high frequency. The plug is subsequently removed leaving the lining in its set position. The coil D is placed permanently within the walls of the furnace. The plug has a melting point higher than the temperature at which the refractory material is fritted or fused, and may consist of graphite, steel, nickel-chrome alloys, or compressed and fritted masses of tungsten. Two or three layers of paper may be wrapped around the plug to enable it to be withdrawn after the paper has been charred and the refractory material has been fused.

INDUCTION FURNACE FOR HIGH TEMPERATURE ENTERPRISE

INDUCTION FURNACE FOR HIGH TEMPERATURE OPERATION

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 cool~down 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 ...

Method for longitudinal graphite coating of bodies of carbon electrodes and device which implements said method

FIELD: graphite coating of carbon members. SUBSTANCE: method involves using set of stationary spaced dielectric fire-proof ribbed resting members which are located on dielectric stationary platform. Every resting member has pair of adjacent U-shaped holes which are positioned side by side, have open top and are spaced from main platform. They are also spaced from one another by means of piece of fire- proof ribbed member strut which is designed as whole. Multiple resting members are located in parallel, so that U-shaped holes match. In addition furnace has multiple insulated U-shaped solid metal sections with open top which external, internal and bottom surfaces are spaced from main platform which is located between adjacent resting members. Ends of metal sections are located in U- shaped holes of resting members. Adjacent metal sections are spaced by vertical air duct which is formed by pieces of resting members, piece of main platform and side surfaces of metal sections. Vertical air duct is open from top and bottom and increased speed shaped as Venturi tube, which bottom hole provides forced air cooling of metal sections of furnace. This results in possibility to decrease cooling time of graphite-coated electrodes down to temperature which allows safe removal of electrodes from furnace.
