A method for operating a power-compensated fusion furnace that includes a power control system having one switching device per heating element, power measurement circuitry, a master temperature sensor, and a controller. Each switching device is electrically connected to a respective heating element. The controller, in conjunction with the switching devices, is able to individually control the electrical energy flowing to each heating element, thereby controlling the duty cycle of each heating element. The duty cycles are corrected for one or more of variations in the electrical resistance of each heating element and position-dependent variations in furnace cavity temperature.

An electrode includes a network of compressed interconnected nanostructured carbon particles such as carbon nanotubes. Some nanostructured carbon particles of the network are in electrical contact with adjacent nanostructured carbon particles. Electrodes may be used in various devices, such as capacitors, electric arc furnaces, batteries, etc. A method of producing an electrode includes confining a mass of nanostructured carbon particles and densifying the confined mass of nanostructured carbon particles to form a cohesive body with sufficient contacts between adjacent nanostructured carbon particles to provide an electrical path between at least two remote points of the cohesive body. The electrodes may be sintered to induce covalent bonding between the nanostructured carbon particles at contact points to further enhance the mechanical and electrical properties of the electrodes.

The invention relates to a sidewall for use in a sintering pallet car. The sidewall has a base for connection to a frame of the pallet car and a wall extending upwardly from the base to a top. The wall has opposing ends, opposing interior and exterior faces, and a height as measured from the base to the top. An elongate brace is disposed on the exterior face intermediate of the opposing ends, the brace extending downwards from the top towards the base. The sidewall may include an arcuate protrusion disposed on the interior face intermediate the opposing ends of the sidewall or a cap extending between the opposing ends of the sidewall and joining the exterior and interior faces, the cap having a protruding lip extending from the exterior face. The sidewall may comprise a top segment and a bottom segment, releasably securable to each other.

A sintered body production method includes a first step in which temperature elevation is started based on a first temperature elevation program in a firing furnace in a state where a molded body containing a metal powder and an organic binder is placed in the firing furnace, a second step in which a vacuum degree or a dew point in the firing furnace is measured in the course of elevating the temperature, and a third step in which temperature elevation is performed by applying a second temperature elevation program in place of the first temperature elevation program when the vacuum degree or the dew point measured in the second step does not satisfy a predetermined condition, and temperature elevation is performed by applying the first temperature elevation program when the vacuum degree or the dew point measured in the second step satisfies the predetermined condition.

The invention relates to a method and equipment for the continuous sintering of mineral material in a sintering furnace (S). In the method, a material bed (2) is formed on a conveyor base (1), the material bed (2) is conveyed by the conveyor base (1) through the process zones (I-VII) of the sintering furnace that have different temperatures, the zones including at least one drying zone (I), at least one cooling zone (VII), and at least one other process zone (II, III, IV, V, VI) between the said drying zone and cooling zone, and gas is conducted through the conveyor base and the material bed (2), when the material bed travels through the process zones (I-VII), and gas is circulated in a circulation gas duct (3) from the last cooling zone (VII) to the drying zone (I). Part of the gas flow that is conducted to the drying zone (I) in the circulation gas duct (3) is removed as an exhaust gas flow (B) by the exhaust gas blower (5) of an exhaust gas duct (4). The volume flow of the exhaust gas flow (B) is regulated by regulating the blowing power of the blower (5) to control the temperature of the gas flow travelling through the material bed in the drying zone.
