Effect of Carbon on Precipitation of MnS Inhibitor in Grain-oriented 3% Silicon-steel
The solubility of MnS in 3% silicon-steel was shown to depend on carbon content. An increase in carbon concentration raises sharply the temperature, below which the solution becomes supersaturated, and leads to growth of the driving force for MnS precipitation. The effect of these factors on the strength of the sulphide particles as inhibitors of the primary recrystailization process was discussed and correlation between thermodynamic parameters of the precipitation reaction and magnetic properties of the finished grain-oriented steel were established.
