The invention relates to iron and steel making with hydrogen and belongs to the metallurgical industry. Fe2O3 or Fe3O4 ore is heated and reduced through hydrogen energy and is made into iron and steel. In the metal smelting process, the Fe2O3 or Fe3O4 ore is heated and reduced into...
Steel making generates, according to climate-change watchdog Bellona Foundation (bellona.org), an average of 1.9 tons of C[O.sub.2] for each ton of steel produced. Cleaner Steel-making with Hydrogen This introduction to steel making identifies the raw materials needed to produce steel, explains...
With the fast-developing technological scenario in respect of renewable energy and electrolysers for the production of hydrogen, it is expected that green-hydrogen based steel may become cost competitive over the next few years, the steel ministry said. To assess the potential for use of Green...

Also it is discussed which reduction methods are the most promising ones and which scientific bottleneck questions must be solved to make Green Steel become reality. Therefore, the presentation addresses some recent progress and...
A method of ironmaking using full-oxygen hydrogen-rich gas which includes hot transferring and hot charging the high-temperature coke, sinter and pellet into the ironmaking furnace through transferring and charging device, and injecting ... Y Qi,Q Wang,D Yan,... - 《Central Iron & Steel Rese...
Of these upstream emissions, almost 45 percent are connected to the making of steel and aluminum, and 35 percent to the car's battery. Decarbonization of these elements is possible, but hard. Steel plants need to convert from coal-fired blast furnaces to electric-arc furnace technology, carbon...
Rheological behavior was evaluated using a rotational rheometer (AR2000ex, TA Instruments) furnished with a standard ETC steel parallel plate geometry having a 25 mm diameter. In order to determine the linear viscoelastic region at a frequency of 1 Hz, the samples were subjected to a strain swee...
Two challenges in coupling analytical instruments and steel processes such as DRI are the location and condition of the gas samples. Steel plants are usually sprawling industrial complexes with distances to some sample points being more than 250m (820ft). The condition of the sample is frequently...
