Characteristics 1. 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. Prevent spheroidizing recession,improve spheroidizing rate. 3. Reduce the tendency to white cast .Improve the elongation of ductile iron,improve machinability. 4. Well-closed formation,low wall thickness sensitivity. Application 1. In the hot metal ladle put the inoculant on the nodularizer. 2. Rushen into the hot metal lable with the iron water when the iron tapping. 3. Rush into when ladle-to-ladle. 4. Inoculation with the flow when pouring.(0.2-0.7mm inoculation effect is better) Standard GradeChemical Compositions (%) SizeInstuctions SiZrCaMnAl â?¥(Min)â?¤(Max) SiZr16551.53.51.50.2-2mmMainly used for bags 0.5-2mm 2-4mm 2-6mm SiZr2623.510.80.763-250MeshUsed for centrifugal casting tube SiZr3751.72.5-1.50.4-2mmMainly used for bags 1-3mm 2-6mm 2-7mm SiZr46551.53.51.50.2-0.5mmUsed for stream inoculation 0.2-0.7mm The specification, packaging and granular size can be produce according to customer demand.
