This study focused on the engineering properties of alkali-activated slag (AAS) pastes prepared by mixing an activator consisting of sodium silicate and sodium hydroxide at room temperature. The water-to-slag ratio of AAS paste was kept constant at 0.35 by mass. AAS pastes were prepared using the activator with five different silicate moduli of 1, 1.2, 1.4, 1.6, and 1.8 and three different Na ...

Oct 17, 2022Slag refining of molten Si-Fe alloy was investigated with the ultimate goal of producing silicon suitable for solar cell application. Multiple compositions of quaternary slag of CaO-Al2O3-SiO2-Na2O were used to treat Si-20 wt pct Fe alloy at 1300 °C. Partition ratio of B increased with increasing the slag basicity, and the maximum partition ratio of boron was found to be 4.3. The ...

Desulphurization of Liquid Steel. Solubility of sulphur (S) in liquid iron (Fe) is quite high. But the solubility of S in solid iron is limited. It is 0.002 % in ferrite at room temperature and 0.013 % in austenite at around 1000 deg C. Hence, when liquid steel cools down, sulphur is liberated from the solution in the form of iron sulphide (FeS ...

A viable heat recovery system must be simple, cost-effective and should not interfere with the industrial process. CIC energiGUNE and Sidenor I+D in the framework of the RFCS ECOSLAG project have developed a new heat recovery concept to capture the heat content of the molten slag using an underground heat exchanger in the slag pit. This solution accomplishes these requirements.
