Production of Anticorrosion Coating Material by Converter Dust with MgO and Cr2O3.

Using converter dust as salt packing, adding MgO and Cr2O3, a high anticorrosion solid coating material was produced. The influences of adding MgO and Cr2O3 (ranging 10%~20%) on the performance of high anticorrosion solid coating were studied. The results show that when the amount of MgO(10%~20%) in converter dust increases, feeding MgO and Cr2O3 is beneficial to the decrease of coating solid component, but feeding only Cr2O3(10%~20%) has little effect. Thus, it is advisable to add MgO and Cr2O3 to improve the resistance of the coating to salt water and acid. The coating of 120h acid corrosion was almost no corrosion phenomenon.
