Properties and Uses of Iron and Steel Slag MF 182-6 NATIONAL SLAG ASSOCIATION Page 5 Granulated blast-furnace slag is produced by quickly quenching (chilling) molten slag to produce a glassy, granular product. The most common process is quenching with water, but air or a combination of air and water may be used.

Jan 09, 2013 · In steel making the reaction between carbon and dissolved oxygen is of utmost importance. Generally pig iron contains about 4 wt% carbon. The solubility of carbon in steel is effected by the presence of impurities and alloying elements. Presence of Nb, V, Cr, Mn and W increase solubility of carbon in iron where as presence of Co, Ni, Sn and Cu decrease it.
