Iron oxide desulfurizer can be used as raw materials or hydrothion removal in the fields of chemical fertilizer. Iron oxide desulfurizer is a kind of solid desulfurizing agent, its principle is to put the sulfur-containing compounds in waste gas adsorption into the holes of desulfurizer, thereby purifying gas.As desulfurizer reaches saturation, namely its desulfurization ability is no longer, need to be recycled, such as by steam stripping regeneration.Ferric oxide desulfurizer, however, after using for a long time, its activity will continue to decline, as the holes is obstructed by some impurity content, the desulfurizer inactivation.The waste desulfurizer can be recycled, the active ingredient.The desulphurization of liquid steels with a refining ladle slag is one of the most important processes of secondary steelmaking. The desulfurizing agents are injected into molten steel either in form of powder transported by an argon blown to the steel through a lance or in form of a cored wire containing powder of desulfurizing agent.
In Steel Desulfurization, several factors simultaneously effect the extent of sulfur removal from the molten steel:
capacity/potential of the slag for sulfur removal
steel-slag reaction
oxidation state of the steel/slag
slag basicity/amount/viscosity
temperature
