In order to examine the effect of ageing on P removal capacity, the phosphorus (P) removal capacity of three types of slag, argon oxygen decarburisation slag (AOD), blast furnace slag (BFS) and electric arc furnace slag (EAF), was examined after 0, 10, 13 and 19 months in batch experiments. The results showed that ageing reduced P removal capacity, e.g. by 78.4% for 19-month-old AOD slag. For B...

Abstract A calculation model of activity for CaO–SiO 2 –MgO–Al O 3 –TiO slag is established according to molecular-ion coexistence theory structure calculate the activities Al , SiO and TiO in slag. The possibility reduction during refining analyzed by thermodynamics verified laboratory industrial experiments. Both theoretical analysis experimental results show that content ladle significantly ...

Recently, steel structures have been accounted for a large percentage of the buildings due to their advantages such as higher execution speed and easier construction. In steel structures, welded joints are commonly used and their quality plays a key role in stability of buildings under applied loads. Hence, to increase resiliency of welded steel structures against natural hazards, welded joints...

Slag fuming is a process of extracting zinc from molten slag in the form of metal vapor by injecting or adding a reducing source such as pulverized or lump coal, natural gas, etc. Top Submerged Lance (TSL) technology has been successfully applied to extract zinc by a fuming process from residues from the zinc industry, ISF and QSL slag and Lead blast furnace slag. A Computational Fluid Dynamic ...

Magnesium slag is a valuable resource when proper disposal and utilization are adopted. The main pollution of magnesium caused dust fluorine pollution. Formation mechanism fine investicated. Alike steel slag, phase transition dicalcium silicate in around 500 °C brings volume expansion, which causes the disintegration powdering slag. Chamical stabilization experiments were carried out. effects p...

The replacement of natural resources in the manufacture of cement and sand is the present issue in the present construction scenario. Copper slag and Ground Granulated Blast furnace Slag (GGBS) are industrial by-product materials produced from the process of manufacturing copper and iron. Use of Copper slag and GGBS does not only reduce the cost of construction but also helps to reduce the impa...
