Silicon Barium The silicon-barium inoculant is a massive metallurgical material obtained by mixing silicon powder and barium powder according to the required proportion, and then steel-making in a high-temperature furnace. It is an additive in the casting process of the foundry. It 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. Within (about 5-8 minutes) have good results. Specifications: Silicon鈮?5 Barium 2.0-6.0 Calcium 1.0-2.0 Aluminum 1.0-2.0 Silicon barium inoculant function 1. Strongly increase the graphitized core, refine the graphite, promote the A-type graphite in the gray iron castings, and improve the strength. For the ductile iron castings, the graphite in the ductile iron can be made small and round, and the spheroidization grade is improved. 2. It can effectively reduce the subcooling degree of molten iron, promote the precipitation of graphite, significantly reduce the tendency of white mouth, reduce the relative hardness, and improve the machining performance of castings. 3. Strong anti-recession ability, the anti-recession time is twice that of 75 silicon, the addition amount of silicon-barium inoculant is lower than half of 75 ferrosilicon inoculant, and at the same time prevents the associated spheroidization recession. 4. Small wall thickness sensitivity, improve section uniformity and reduce shrinkage tendency. 5. The chemical composition is stable, the processing granularity is uniform, and the composition and quality deviation are small. 6. Low melting point (below 1300掳), easy to absorb and melt during inoculation treatment, and very little scum. Common particle size of silicon-barium inoculant: 0.2-0.8mm, 1-3 mm, 3-8mm, 8-15mm can also be customized Transport Packaging: Generally, it is packaged separately in 25kg small bags, and the outside is packed in large bags.Silicon Barium website:http://www.aonmetals.com/silicon-alloy/silicon-barium/
