1. Ferro Silicon Zirconium Strong increase graphitization core ,the sharp increase of graphite ball from number ,refine graphite graphite ball,promote praphite in ductile iron tend to be complete;
2. Ferro Silicon Zirconium Prevent spheroidizing recession,improve spheroidizing rate.
3. Ferro Silicon Zirconium Reduce the tendency to white cast .Improve the elongation of ductile iron,improve machinability.
4. Ferro Silicon Zirconium Well-closed formation,low wall thickness sensitivity.
1. Ferro Silicon Zirconium In the hot metal ladle put the inoculant on the nodularizer.
2. Ferro Silicon Zirconium Rushen into the hot metal lable with the iron water when the iron tapping.
3. Ferro Silicon Zirconium Rush into when ladle-to-ladle.
4. Ferro Silicon Zirconium Inoculation with the flow when pouring.(0.2-0.7mm inoculation effect is better)
