mill scale

mill scale Manufacturing ferrosil icon alloy smelting ferrosil icon alloy steel scurf of main raw material is each year, smelting ferrosil icon alloy steel scurf consumption in 200 million t left and right sides, with oxidized scale alternative steel scurf smelting process has matured ferrosil icon alloy and has been applied.Sintering raw material is oxidized scale sinter good complementary makings, on one hand, oxidized scale relatively granularity relatively bulky, can improve the permeability of sintering raw material layer, on the other hand, the oxidized scale of Fe2O3 FeO combustion in oxidized to the process of exothermic, can lower the solid fuel consumption, but also improve sinter productivity, experience shows that 8% of oxidized scale could increase about 2%.
