GB 72 ferrosilicon processing ferrosilicon, silicon is short for silicon particle, namely the ferrosilicon inoculant, used for steelmaking, ironmaking a nucleating agent.
Features:
1, the composition is uniform, small segregation;
2, particle size uniformity, no powder, inoculation effect;
3, inoculation effect than the common ferrosilicon, tend to produce slag is small;
4, extend the die life, reduce surface defects;
5, reduce the pore, improve the quality of pipes surface, increase a especially qualified rate;
6, eliminate miniature pine, improve casting processing performance.
