Products Description
With the increase of the amount of silicon metal powder, the change of iron groove material line gradually decreases, the bulk density increases, the porosity gradually decreases, the flexural strength gradually increases, the oxidation resistance increases, and the slag erosion resistance is the best when the amount of silicon metal powder is added at 2% and 3%. Considering the comprehensive consideration, the amount of silicon metal powder should be 2%.
