    摘要： Cylindrical carbon blanks are assembled into one or more upright stacks which are advanced stepwise in an upward direction in one or more upright tubes which insulate the column or columns from the surrounding atmosphere. The blanks in the upright tube or tubes are preheated by exchanging heat with an inert gas, such as pure argon, and the preheated blanks are thereupon conveyed along one or more horizontal path sections into the upper end of an additional tube wherein the blanks are heated to graphitizing temperature by a series of electrode pairs. The thus obtained graphite electrodes are cooled by inert gas which is thereupon admitted into the upright tube or tubes to preheat fresh carbon blanks.

    摘要： A method for calcining carbonaceous materials in a rotary kiln is disclosed. An oxygen injection lance provides oxygen through the wall of a firing hood and into the carbonaceous bed, which is at an elevated temperature. The oxygen burns a portion of the carbonaceous material, providing the necessary heat for calcining the remainder of the carbonaceous materials in the kiln.

    摘要： Method for calcining carbonaceous blocks into carbonaceous bodies, in which either a continuous or intermittent operation furnace is used. After placing carbonaceous blocks to be calcined onto the loading platform of a cart, a containment structure or enclosure structure is formed around the carbonaceous blocks including a barrier, which is held away from and is adapted to completely enclose the carbonaceous blocks, with the optional exception of barrier formed on the surface of the loading platform on which the carbonaceous blocks rest. The barrier being effective to prevent seepage of air or gases therethrough during calcination. The containment or enclosure structure for implementing the method comprises a conventional cart for continuous and intermittent operation furnaces overlaid by a stacked arrangement including two side-by-side walls of refractory material wherebetween a barrier of carbonaceous powder is interposed, and a cover, including two slabs also formed from refractory material and arranged in two layers wherebetween a further barrier of carbonaceous powder is provided. An additional barrier of carbonaceous powder may be optionally provided on the loading platform of the cart.

    摘要： A modified rotary kiln suitable for calcining normally solid carbonaceous material, having adapted thereto at one end a firing crown and means for admitting combustible gases or liquids and air; a feeding means for such solid carbonaceous material to be calcined adapted to the other end of the kiln; and wherein the combustion gases and solid materials travel countercurrently in the kiln during calcination, wherein: at least one series of at least two tuyeres passes through the wall of the kiln symmetrically spaced to and at about a point longitudinally in the middle one-half of the longitudinal axis of the kiln; each tuyere terminating within the kiln through a nozzle on the side of the tuyere at a height sufficient for the discharge of exterior oxidizing gases passing therethrough at a point above the bed of the carbonaceous material in the kiln, directing the exterior oxidizing gases toward the feed end at about the same acute angular direction from a line passing through the nozzle and parallel to the longitudinal axis of the kiln; at least one shroud which surrounds the kiln and is movably mounted with respect to the kiln wall, thereby allowing the kiln to rotate therewithin, each tuyere terminating on the outside of the kiln within the shroud; means at the junction of each tuyere with the interior surface of the kiln lining to cause forced movement of the carbonaceous material past the tuyeres; and means to cause air or other oxygen-containing gases to flow into the shroud, through the tuyeres, and into the kiln.

    摘要： A method is provided for operating a blast furnace by blowing at least a solid reducing material and a combustible gas into the furnace through tuyeres with a lance inserted into a blowpipe, wherein a tube-bundle type lance obtained by bundling a plurality of blowing tubes is used and when only a solid reducing material or two kinds of a solid reducing material and a combustible gas or three kinds of a solid reducing material, a combustible gas and a gaseous reducing material is simultaneously blown into an inside of the blast furnace through a tube for blowing the solid reducing material, a tube for blowing the combustible gas and a tube for blowing the gaseous reducing material in the tube-bundle type lance, two or more tube-bundle type lances are inserted into the blowpipe to approximate their front ends to each other and blowing is performed so that the respective blowout streams interfere with each other in the blowpipe.

    摘要： The present invention refers to a method and an equipment for curing and drying self-reducing agglomerates containing cement as a binder in the presence of saturated vapor at a temperature from about 70 to about 110° C. and under atmospheric pressure. The treatment is performed in one single equipment. The self-reducing agglomerates are comprised of mixtures of fines of iron ore and/or industrial residue containing iron oxides and/or metallic iron, fines of carbonaceous materials such as mineral coal, charcoal, green petroleum coke and similar fines, fluxing material such as steel plant slag and blast furnace slag, limestone, lime and similar materials, cement as a binder and fluxing agent, and humidity between 7 and 12%, produced in pellet-making units and/or briquette-making units and thereafter treated using one single piece of equipment, involving the steps of predrying with heated gasses (2), curing with saturated vapor (3) and drying with heated gasses (4) performed continuously and sequentially, controlling the discharge velocity (5) in order to allow the time of permanence of the agglomerate within the equipment to be from about 4 to about 12 hours. The cured and dried agglomerate may be processed in an adequate reducing/melting equipment to provide metals and metallic alloys.
