摘要： The present invention relates to a method for converting and separating vanadium, titanium, and iron from the vanadium-titanium-iron concentrate in one step, which includes the steps as below. (1) The vanadium-titanium-iron concentrate is mixed and roasted together with addition agent and reducing agent, and thereby vanadium-containing pig iron and vanadium enriched slag are obtained. (2) The vanadium titanium enriched slag is leached in water and filtered, and thereby vanadium-containing solution and titanium slag are obtained. The technical features of the present invention are as below. By the new process of sodium reduction coupling, a new system of low-temperature smelting multiphase reaction separation is constructed. The reduction of iron, sodiumizing of vanadium, and the melting separation process of the vanadium titanium enriched slag and the iron are achieved in one step. Three products, i.e., the vanadium-containing pig iron, the vanadium-containing solution, and the titanium slag are produced.

摘要： In a method and a device for operating a smelting reduction process, at least part of an export gas from a blast furnace or a reduction unit is thermally utilized in a gas turbine and the exhaust gas of this gas turbine is used in a waste heat steam generator to generate steam. The remaining part of the export gas is fed to a CO2 separation apparatus, the tail gas thereby obtained being fed to a waste heat steam generator and burned for additional steam generation. The combustible components of the tail gas are sent for thermal utilization in a steam generator, so that the overall energy balance of the thermal use of the export gas is improved. In addition, a further part of the export gas is qualitatively improved by the CO2 separation apparatus, so as to generate a high-quality reduction gas which can be supplied for metallurgical use.

摘要： The present invention provides a method capable of producing good hot-briquette iron using high-temperature reduced iron discharged at a high temperature from a reducing furnace such as a rotary hearth furnace. The method includes a temperature control step of cooling the high-temperature reduced iron and controlling the temperature of the reduced iron to an appropriate hot-forming temperature of over 600° C. and 750° C. or less, and a step of producing hot briquette iron by hot-forming the high-temperature reduced iron of the appropriate hot-forming temperature with a briquetting machine. The temperature control step includes substantially horizontally holding a rotating drum having a feed blade spirally provided on the inner periphery thereof, charging the high-temperature reduced iron in the rotating drum and passing it through the rotating drum by rotating the rotating drum while maintaining the inside of the rotating drum in a non-oxidizing atmosphere with inert gas, and cooling the outer peripheral surface of the rotating drum by contact with a cooling fluid during the passage of the high-temperature reduced iron through the rotating drum to indirectly cool the reduced iron so that the temperature of the reduced iron is the appropriate hot-forming temperature.

摘要： A method of obtaining a measure of the stickiness of heated particulate solids (40) includes pouring a sample of the particulate solids (40) onto a generally horizontal support (12) and allowing it to freely form its own angle of repose. The sample is subjected to a predetermined heat and gas atmosphere regime, and the support is rotated about a generally horizontal axis to an angle (42) where the integrity of the sample (40) fails. The angular position (42) is a measure of the stickness of the particulate solid (40).
