??? Calcium oxide sorbent, in the end what kind of desulfurizer? Consider the following description. ??? Before or molten iron smelting it will not underwrite desulfurizer into use into law, the amount is 1.5% -2.0% iron or molten steel, or add the actual situation of customers, require hot metal at temperatures above 1400 degrees Then molten iron or molten steel into the desulfurization effect can be achieved. This product is suitable for steel, iron, alloy desulfurization. ???? Once the chemisorption desulfurization agent react to form a strong chemical bonds, no desorption and, therefore, ruled out the possibility of secondary pollution generated
