Product Features
1. Significantly increasing graphitization core, refine graphite, promote the A-type graphite in grey iron and graphite tending to be round in ductile iron, improve spheroidizing level;
2. Immensely reduce the chilling tendency, reduce relative hardness, improving cutting performance;
3. Strong recession-resistant capability, prevent inoculation and nodulizing recession;
4. Improve the homogeneity of fracture surface, reduce shrinking tendency;
5. Stable chemical composition, homogeneous particle size, deviation in composition and quality deviation is low;
6.Low melting point (near 1300℃), easy to be melt in inoculation processing, little scum.
Application
Ferro silicon strontium inoculant suitable for thin-walled or chilled sweet ash sulfur cast has strong ink capabilities ,but also for ductile iron ball to increase the number of ink , especially high corrosion resistance of nickel ductile iron (containing Ni14%,Cu6%,Cr2%,Si 1.5%) in addition,since it reduces white without significantly increasing the number of eutectic ,especially for applications that require no casting dense loose,the water pressure resistance gray cast to good effect ,strong ink and carbon Si-Ca of molten inoculant different allowable temperature is low .and calcium ,the amount of aluminum is low ,less shaped residue ,no vacuum casting defects.
