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.

BOTTOM STRUCTURE FOR A SMELTING FURNACE

The invention relates to a bottom structure of a suspension smelting furnace to be used in a smelting furnace (1), in the reaction space (2) whereof of sulfidic raw material containing metal, such as copper, nickel or lead, is smelted in the presence of an oxygen-bearing gas and slag-forming agent, in order to render the metal in a form that is advantageous for further treatment, and where the created molten phases (5, 6) are settled onto the bottom (3) of the smelting furnace in order to separate the molten phases fo rm each other, when the temperature of the molten phases is within the range 11 50 - 1450~ C. According to the invention, the bottom structure includes at leas t one arched lining layer (7) inclined in the longitudinal direction of the smelting furnace, so that the temperature on the surface (89 that is opposit e to the surface that gets into contact with the molten phase is below 800~ C.

TAPPING LAUNDER FOR AN IRON SMELT

The invention relates to a tapping launder for an iron smelt, comprising an outer support structure (10), a fireproof lining (16, 18) and a copper lining (20) with ducted cooling. Said copper lining (20) surrounds the fireproof lining (18) in the support structure (10). Solid ribs (32) on the copper lining (20) project deep into the fireproof lining (18). The main purpose of said ribs is to cool any iron smelt which penetrates through cracks in the fireproof lining (18) to hardening, hereby stopping said smelt before it comes into contact with the solid copper base body. This prevents cracks caused by overheating from forming in the solid copper base body, hereby reducing the risk of coolant leaking into the iron smelt.

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 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.

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 ...
