is known that metal which is produced by the method of electroslag remelting (ESR) has service properties superior to those of metal made by open refining and casting. This can be attributed to the better conditions which exist for refining in the specially chosen slag and for the crystallization of the metal in the case of ESR. However, the need for a two-stage metallurgical conversion (essent...

This study investigates a new concept of producing precipitated calcium carbonate (PCC) from steelmaking slag and carbon dioxide via a spray carbonation process. The presented laboratory-scale spray carbonation test reactor uses a spray nozzle to disperse fine droplets of a Ca-rich solution into a spray tower, where calcium carbonate precipitates as a result of the reaction between calcium and ...

Since 10 million tons of steelmaking slag, which contains a few percent phosphorus, are annually produced, the phosphorus amount in slag is equivalent to annual import volume rock Japan. Therefore, attracting attention as potential resources. Phosphorus-concentrated obtained by dephosphorization reaction between high hot metal and oxidizing at temperature phosphorous comparable that rock. Howev...

Steelmaking slag is a by-product of steel making. It has been reused as a material for civil engineering, pavement construction etc. For such applications, it is extremely important to evaluate the amount of free lime, which has the chemical form of calcium monoxide (CaO) and can cause the failure of mechanical properties by volume expansion through absorption of water or carbon dioxide gas. So...
