摘要： A mixer shifts the center frequency of a received signal to a baseband according to a center frequency detected by a center frequency detector or a center frequency estimated from ship speed, for example, by a center frequency estimator. The passband of a variable passband filter varies according to a bandwidth detected directly from the received signal by a bandwidth detector or a bandwidth estimated from the pulselength of a transmitting signal by a bandwidth estimator, whereby the bandwidth of a baseband signal output from the mixer is limited to remove undesired noise components in the received signal.

摘要： The present invention is an apparatus and method for the direct reduction of iron oxide utilizing a rotary hearth furnace to form a high purity carbon-containing iron metal button. The hearth layer may be a refractory or a vitreous hearth layer of iron oxide, carbon, and silica compounds. Additionally, coating materials may be introduced onto the refractory or vitreous hearth layer before iron oxide ore and carbon materials are added, with the coating materials preventing attack of the molten iron on the hearth layer. The coating materials may include compounds of carbon, iron oxide, silicon oxide, magnesium oxide, and/or aluminum oxide. The coating materials may be placed as a solid or a slurry on the hearth layer and heated, which provides a protective layer onto which the iron oxide ores and carbon materials are placed. The iron oxide is reduced and forms molten globules of high purity iron and residual carbon, which remain separate from the hearth layer. An improved apparatus includes a cooling plate that is placed in close proximity with the refractory or vitreous hearth layer, cooling the molten globules to form iron metal buttons that are removed from the hearth layer. The improvements due to the present apparatus and method of operation provide high purity iron and carbon solid buttons, which are separate from slag particulates, and discharged without significant loss of iron product to the interior surfaces of the furnace.

摘要： Molten iron is prepared by (1) providing iron oxide and a carbonaceous reducing agent, (2) preparing a shaped product from the carbonaceous reducing agent and the iron oxide, (3) preparing solid reduced iron from the shaped product, wherein the solid reduced iron has a metallization of at least 60%, a specific gravity of at least 1.7, and a carbon content of at least 50% of the theoretical amount required for reducing the iron oxide remaining in the solid reduced iron, and, (4) before substantial cooling occurs, heating the solid reduced iron in an arc heating-type melting furnace at a high temperature. The molten iron can be prepared efficiently from iron ores of relatively low iron content without causing erosion of refractories, at high energy and high reduction efficiencies, and by a simple operation in a simple facility.
