WebReal time analysis of top gas provides means of controlling the process tighter to minimize the use of fuel (coke) but maximize production of steel. Achieved by monitoring the CO 2 / (CO+CO 2) ratio. CO too high indicates using too much coke. CO2 too high indicates chemical reaction is too hot. Safety issue: hydrogen monitoring – especially ... Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as

WebApr 4, 2012 · In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag–metal reactions. http://resources.schoolscience.co.uk/Corus/14-16/steel/msch1pg1.html
