1. for ductile iron, gray iron.Silica-barium inoculant can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic groups, and refine the matrix structure. It has a good effect in a short time (about 5-8 minutes) after inoculation.It is mainly applicable to the general nature of various situations or the transient incubation in the later stage.
2. Silicon barium inoculant is mainly used for inoculating ductile iron and gray cast iron Bridle fluid.The silica-Barium inbreeding agent strongly increases the graphitization core, refines the graphite, promotes the a-type graphite in the gray cast iron, improves the strength, and can make the graphite in the nodular cast iron fine and round and improve the spheroidization grade.It is highly recession-resistant and prevents the associated spheroidizing recessions.The sensitivity of wall thickness is small and the tissue is uniform.It can significantly reduce the tendency of white mouth, reduce the relative hardness and improve the machining performance of casting.Used as inoculant and spheroidizer in cast iron industry.
The size of silicon barium inoculant is: 0-0.25mm: For inoculating in type (precise inoculating, higher efficiency)
0.2-1mm: Used for flow inoculation (the inoculation quantity is controlled accurately), 1-3mm and 3-8mm are used for in-bag inoculation (the inoculation time must be controlled above 70% of the iron-producing time), and 8-15mm are used for in-furnace inoculation.
