摘要： A graphite electrode for an electrothermic reduction furnace is formed from anode grade coke and graphitized at a graphitization temperature below 2700° C. The resulting electrode is particularly suited for carbothermal reduction of alumina. It has an iron content of about 0.05% by weight, a specific electrical resistivity of above 5 μOhm·m, and a thermal conductivity of less than 150 W/m·K. The graphite electrode is manufactured by first mixing calcined anode coke with a coal-tar pitch binder, and a green electrode is formed from the mixture at a temperature close to the softening point of the pitch binder. The green electrode is then baked to carbonize the pitch binder to solid coke. The resultant carbonized electrode, after further optional processing is then graphitized at a temperature below 2700° C. for a time sufficient to cause the carbon atoms in the carbonized electrode to organize into the crystalline structure of graphite.

摘要： A threaded connection is secured against loosening/unscrewing for columns of carbon and/or graphite electrodes. The electrodes are connected in columns with threaded connection elements, i.e., carbon connecting pins. At least one part has a wedge ramp on the root of the thread winding. When the components of the threaded connection are screwed together, the crests of the thread windings of one part abut with the wedge ramps of the other threaded connection component. A contact line is created, possibly multiple sections of a contact line. When the parts are screwed together, all forces are transferred from one part to the other only via the contact line. In a special case, the contour of the thread winding along whose root the wedge ramp is running is reduced e.g. to a connecting line between two wedge ramps located one above the other in the cross-section.

摘要： A carbon material is formed by heat-treating a carbonaceous material in a reaction mix of oxides of boron and boron nitride in a nitrogen atmosphere to temperatures of 1600 to 2000° C. The surface of the carbonaceous material is transformed into a carbon material that is resistant to oxidation to temperatures of 900° C., enabling machined components to be utilized for weeks at that temperature. The carbon material is also stable in inert or vacuum environments to temperatures in the range of 1500 to 2000° C., enabling its use as aluminum evaporative boats and the like.

摘要： A cylindrical graphite electrode with a consumable end includes one or more slots comprising a discontinuous portion of the carbon which extend along the length of the carbon body through at least a portion of the cross-section substantially to the consumable end. The slot may extend from the surface into the body or the slot may extend within the body below the surface. The slot may be filled with a carbonaceous material different from the carbon of the body. The slot may extend helically along the length and around a portion of the periphery of the body. The slots may be formed prior to or after heat treating of the electrode. As the electrode is exposed to a thermal shock, a crack is initiated in and propagates along the electrode and intersects with the slot, wherein substantial further growth of the crack is arrested at the slot.

摘要： The subject invention is a plug for sealing recesses in anode blocks designed to hold anode rods, wherein the anode blocks are intended for the electrolytic extraction of base metals during their calcination treatment. The proposed plug is characterized by the fact that it is die-formed and composed of a material containing cellulose. This provides a very close seal in the anode recess, such that coke granules, which are inserted as fill material to displace oxygen in gaps between several anode blocks within a calcining furnace, cannot enter the anode recesses. Undesirable conglutination inside the anode recesses and burning of the material defining the anode recesses, caused by the unavoidable presence of some oxygen residue during the calcination process, can no longer occur. Because of the great solidity of the plug, deformations of the recesses in the lower rows of anode blocks in the calcining furnace are prevented. At the conclusion of the calcination process, after the anode recesses are precipitation-hardened, the cellulose containing plugs are carbonized, whereby the coal or ashes remaining in the recesses can be removed by vacuuming, without any difficulty in a subsquent operation.
摘要翻译： 本发明是用于密封阳极块中用于保持阳极棒的凹部的插头，其中阳极块用于在其煅烧处理期间电解提取贱金属。 所提出的插塞的特征在于它被模制并由含有纤维素的材料组成。 这在阳极凹部中提供非常密封的密封，使得作为填充材料插入的焦炭颗粒在煅烧炉内的几个阳极块之间的间隙中置换氧气不能进入阳极凹部。 阳极凹陷内的不希望的粘连和限定阳极凹部的材料的燃烧由于在煅烧过程中不可避免地存在一些氧残余物而不能再发生。 由于插头的牢固性，因此能够防止煅烧炉中的下排的阳极块的凹部的变形。 在煅烧过程结束时，在阳极凹槽沉淀硬化之后，将含纤维素的塞子碳化，从而通过抽真空除去残留在凹槽中的煤或灰分，而不需要任何困难。
