摘要： At least a percentage of iron ore pellets and the like for use in a direct reduction process for the production of sponge iron are coated with a thin porous coating of Portland cement to counteract tendency to aggregate. This is accomplished by method and apparatus that mixes water and cement powder at the point of delivery in a manner such that no pumps are subjected to a wet cement slurry. The slurry is mixed and maintained in suspension by air agitation in a bin and then flowed through a bin discharge pipe and sprayed therefrom onto a passing layer of pellets in a controlled manner by regulated air injection into the discharge pipe.

摘要： A method for the direct gaseous reduction of iron ore to sponge iron at an elevated temperature suitable for hot briquetting, wherein a hot reducing gas is circulated upwardly through a descending body of iron ore and a make-up reducing gas stream is added to the circulating gas stream. A sponge iron product having a predetermined desired degree of carburization in the range 0.5% to 4% is obtained by adding a controlled flow of natural gas or other methane-containing gas to said make-up gas stream or to said circulating gas stream.

摘要： A method for the gaseous reduction of iron ore to sponge iron in a vertical shaft moving bed reactor (10) wherein a hot gaseous mixture of hydrogen and a carbon monoxide is used to reduce the ore. It has been found unnecessary to use the external catalytic reformer of prior art processes to reform the methane and other hydrocarbon constituents of the natural gas commonly used as a source of gaseous reductants. By establishing a reducing gas recycle loop to which make-up natural gas and steam are fed in the proper proportions, the product sponge iron in the reactor (10) can be used to catalyze hydrocarbon reformation, provided that the carbon content of the recycled gas is maintained low by removing carbon dioxide therefrom. When pure methane is employed, steam/methane molar ratios within the preferred range of 1,4: 1 to 2.2: 1 are used.

摘要： The invention relates to a mould plate of a continuous casting plant. Said mould plate consists of copper and comprises a working surface (2) which faces a metal melt (3) or a (partially) solidified metal strand when the continuous casting plant is in operation and at least one cooling surface (5, 5') which is in contact with a cooling medium when the continuous casting plant is in operation. The mould plate has a heat conductivity (W) and extends over a mould length (L) in the direction of casting (x). According to the invention, a layer (7) with a heat conductivity (S) which is less than the plate heat conductivity (W) of the mould plate is applied to the cooling surface (5, 5') in at least one partial area.

摘要： The present invention relates to a method and apparatus for separating undesired toxic metals, such as Zn, Pb and Cd, from iron-containing materials by: sintering a mixture of such materials (typically including EAF dust and mill scale) with carbonaceous particles to form sturdy sinter lumps; preheating such lumps in a non-reducing atmosphere, if needed, to achieve an elevated temperature generally above the vaporization temperature of the undesired metals, but below the sticking temperature of said iron-containing lumps (which is typically below the vaporization temperatures of such undesired metals in their oxide form), feeding the lumps at such elevated temperature into a reduction reactor; flowing hot reducing gas through said lumps to volatilize said undesired reduced metals and carry the volatilized metals out of said reduction reactor leaving the iron-containing lumps largely stripped of the undesired metals and ready for discharge and safe and/or useful disposal or re-use, and finally cooling the off gas from the reactor to separate out the resulting solidified unwanted metals (typically in their oxide form resulting from a water quench cooling).
