IPC: C21B11/00
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a melting method of iron scrap which improves the utilizing efficiency of combustion heat of carbonaceous material by using inexpensive carbonaceous material to improve the secondary combustion ratio and causes small erosion of a refractory and small scattering loss of slag and dust to the outside of a furnace even if gaseous oxygen supplying speed per unit vol. in the furnace is same as or quicker than that of the ordinary converter method. SOLUTION: At the time of melting the iron scrap and reducing iron oxides by charging the iron scrap containing the iron oxides, the iron path 10 and molten slag layer 11 on the iron bath are formed in a melting furnace and the carbonaceous material and gaseous oxygen are supplied on the molten slag layer 11 to burn the carbonaceous material. Further, in the iron content in the charged iron raw material, wt. ratio of the iron content in the iron oxide is adjusted in the range of 0.02-0.3 and atmospheric pressure P (10<2> kPa) in the melting furnace is adjusted in the range as the following inequality. 0.005(F/ V)+1.0<=P<0.01(F/V)+3.0. Wherein, F is the supplying speed of gaseous oxygen (Nm<3> /h) and V is the inner vol. of melting furnace (m<3> ).

Abstract: PURPOSE:To shut out the circulation of exhaust gas in the initial period of combustion by a method wherein an air injection nozzle is provided so as to be opposed to the exhaust port of the exhaust gas in an ejector and air is ejected out of an air ejecting nozzle in the initial period of combustion of a burner to evacuate the inside of a tube. CONSTITUTION:In an ejector 5, the tip end ejecting port of an air discharging nozzle 7 is opposed to the front surface of an exhaust gas discharging port 6 with some interval. High-speed preheating air is ejected out of an ejector nozzle 9 toward a downstream side preheating air supplying tube 3 formed so as to be a tapered venturi tube whereby the inside of the ejector 5 is evacuated and exhaust gas is induced out of the exhaust gas discharging port 6.

Abstract: PURPOSE:To realize a 16 Mbit DRAM by forming a capacitor dielectric film, with one-third of the conventional one in thickness and reduced leakage current, to increase capacitance per unit area so that memory cells may be reduced in size. CONSTITUTION:A polysilicon storage electrode 106 is formed on a windowed insulating film 105 formed on a diffused layer 103. A silicon nitride film is formed, and it is then oxidized in an oxygen-steam atmosphere at approximately 900 deg.C to form a silicon oxide film. After the silicon oxide film is removed by wet etching with a solution of hydrofluoric acid, a second silicon oxide film is formed by thermal oxidation in an oxygen-steam atmosphere at approximately 850 deg.C. As a result, a double-layer structure is formed as the dielectric film of a capacitor. A polysilicon film is grown to a thickness of 100nm to form a capacitor electrode 107. The capacitor dielectric thus formed has very few pin holes and weak spots, and good electric characteristics with less leakage.
