CO2 has characteristic properties and reactions at the converter smelting temperature, chemical reaction between elements such as C Si in molten pool bubble proliferation cooling effects, which can effectively improve kinetic thermodynamic conditions of smelting. Here, an experimental study industrial test on application were carried out. The effects Mode-1 Mode-2 with total injection amounts 2...
In this paper, an innovative method is proposed to upgrade iron and remove phosphorus from high-phosphorus oolitic hematite ore by the sodium magnetization roasting–magnetic separation–sulfuric acid hydroxide leaching process. The process parameters of roasting, leaching, alkaline were optimized. results show that only adopting traditional separation, concentrate containing 57.49% Fe 1.4% P2O5 ...
In this paper, the influence of Fe2O3 addition amount on dephosphorization hot metal at 1623 K with slag low basicity (CaO/SiO2) about 1.5 was investigated by using high-temperature laboratorial experiments. With increasing from 5 to 30 g, contents [C], [Si], [Mn] and [P] in end are decreased corresponding removal ratios increase. slags, phosphorus mainly exists form nCa2SiO4–Ca3(PO4)2 solid so...
Electrochemical water splitting into hydrogen and oxygen is a promising technology for sustainable energy storage. The development of earth-abundant transition metal phosphides (TMPs) to catalyze the hydrogen evolution reaction (HER) and TMP-derived oxy-hydroxides to catalyze the oxygen evolution reaction (OER) has recently drawn considerable attention. However, most monolithically integrated m...
