Steps in the Modern Steelmaking Process thebalanceChemical Reagents for Enhanced Coal Flotation Coal

May 16 32 Primary steelmaking has two primary methods BOS Basic Oxygen Furnace and the more modern EAF Electric Arc Furnace methods BOS methods add recycled scrap steel to the molten iron in a converter At high temperatures oxygen is blown through the metal which reduces the carbon content to between 0 15 percent EAF methods however feed Sep 15 32 More important was the performance of these compounds as promoters for oxidized coal flotation Finally joint collector flotation experiments were conducted and the results showed that a very small addition of a THF reagent before the dodecane addition greatly enhances the flotation of coal

Slag foaming practice in the steelmaking process Influence of the Slag Density on the Splashing Process in

Despite the fact that this is a simplified method when compared with the conditions found in a practical operation of the steelmaking process as it does not consider the slag refractory and slag metal interactions these studies are still important from a technical point of view as will be discussed in the following section 21The way in which slag density influences the slag splashing phenomenon in an oxygen steelmaking converter is numerically analyzed in this work Several values of the density of the slag are considered and their effect on the global mass balance and slag average volume fraction on the sidewalls of the converter is studied using isothermal two dimensional transient computational fluid dynamics
