| 181 | Environment-friendly Non-noise matte Granulation Technique | US12340697 | 2008-12-20 | US20100154941A1 | 2010-06-24 | SONGLIN ZHOU; Weidong Liu |
| The invention makes public an environment-friendly non-noise matte granulation technique. Melted matte flows out from the chute, then gas is sprayed on the matte through spray facilities; the gas disperses the melted matte into a large amount of tiny liquid drops, and cools the dispersed tiny drops to semi-melted or solid copper grains; in the following dropping course, the copper grains are quenched by pressurized cold water; finally, copper grains drop to the cold-water pond along with the pressurized cold water for further cooling, and the produced sand-like mattes are sent to the next procedure through dehydration-and-transportation system. It can overcome explosion and prevent chemical reaction in quenching, reduce noise pollution, and has the properties of simple procedure and easy operation to settle the problems existed in water quenching of matte. | ||||||

| A method for producing hydrogen and/or other gases from steel plant wastes and waste heat is disclosed. The method comprises the steps of providing molten waste from steel plant like molten slag in a reactor. The molten slag is contacted with water and/or steam in the presence of a reducing agent to form a stream of hydrogen and/or other gases. The hydrogen and/or other gases can then be extracted from the stream of gases from the reactor. | ||||||

| A method for aging steel-making slag comprising the steps of charging normal temperature steel-making slag crushed to the extent that the slag having a grain diameter of 25 mm or less which constitutes 80% or more of the total amount into a pressure vessel which can be closed tight enough to seal a pressure substantially higher than atmosphere. The pressure vessel is closed and pressureized steam is supplied into the said vessel for heating the said pressure vessel and slag to raise the temperature and the pressure in the said pressure vessel while discharging condensed hot water. The interior of the vessel is kept under a condition saturated by steam and pressurized up to 2 to 10 kg/cm.sup.2 G for 1 to 5 hours. The pressure in the pressure vessel is reduced to be equalized with atmosphere. The steel-making slag is then discharged from the vessel. Apparatus is provided for carrying out the above process and includes a pressure vessel having an opening lid for charging and discharging steel-making slag. A steam generating apparatus connected via a pipe having a valve to upward of the pressure vessel. A pipe having a steam trap connected at the lower position of the pressure vessel so as to discharge hot water. A pipe having a valve connected to the upper portion of the pressure vessel and open to the atmosphere so as to reduce the pressure in the interior of the pressure vessel. | ||||||

| Rubber-base wastes, such as tires and industrial rubber wastes, may be disposed of, without pretreatment thereof, by contacting the wastes with molten metallurgical slag on the site of the production of the slag. The molten slag causes flash thermal decomposition of the rubber-base wastes in a non-polluting manner. The solidified slag products obtained are useful for soil improvement or construction work consolidation. | ||||||
