|20120055286||METHOD OF MANUFACTURING DIRECT REDUCTION IRON AND REDUCTION FIRING APPARATUS - The present invention provides a method of manufacturing direct reduction iron and a reduction firing apparatus. The apparatus may be a dual-chamber stepping reduction furnace, a single chamber stepping reduction furnace or a single hearth down-draft reduction furnace, wherein the dual-chamber stepping reduction furnace includes a left chamber, a right chamber, a material containing device, a step mechanism, a slag distributing device, a charging device, heating burners, a fume extraction path, a charging device, a material receiving tank having a sealing cap and a slag discharging path. The method mainly includes the following steps: distributing and charging the slag in the material containing device; carrying and sending the material containing device through a preheating station, a heating station and a reduction station sequentially by the step mechanism; meanwhile, heating the material to be reduced by a combustion of the fuel with the heating burners; discharging the reduced material into the material receiving tank having the sealing cap from the material device; placing the material device from which the material is discharged into the feeding side of the other chamber, then a next work circulation begins. The present invention has features such as a small limitation of resources shortage, low energy consumption, a low-carbon environment, high production efficiency, a low production cost, a high metallization rate, a long life-span of the apparatus and a wide range of production applicability and so on.||03-08-2012|
|20110256420||HOT-DIP GALVANIZED STEEL PLATE AND PRODUCTION METHOD THEREOF - The invention provides a hot-dip galvanized steel plate with high adhesion between a plating layer and base steel, and belongs to the field of manufacturing hot-dip galvanized steel plates. Atomic concentration ratio Al/Zn of Al and Zn in a Fe-Al intermediate transition layer between a base steel and a plating layer of the hot-dip galvanized steel plate is 0.9-1.2. The plating layer did not have Γ phase, but has relatively thin δ phase and little ξ phase. The plating layer mostly consists of η phase, thus obviously improving adhesion, scratch resistance and wear resistance of the plating layer.||10-20-2011|
|20100243468||METHOD FOR PREPARING METALLIC TITANIUM BY ELECTROLYZING MOLTEN SALT WITH TITANIUM CIRCULATION - The present invention provides a method for preparing metallic titanium by electrolyzing molten salt with titanium circulation. The method mainly comprises reducing titanium tetrachloride (TiCl||09-30-2010|
