INOCUL is a product in granular form used as an inoculants for treatment of cast iron metal in ladle. When the molten cast iron is treated with INOCUL then it enhances reduction in chill, improvement in mechanical properties & machinability.
Inoculation is useful for the production of sound casting with uniform mechanical properties throughout the section.
INOCUL should be added to the clean molten metal. The best way of inoculation is to add INOCUL in the stream of metal as late as possible. Addition rate is most important since it is harmful to over-inoculate as well as to under inoculate. Over inoculation increases shrinkage and porosity in susceptible casting
The choice of grade of inoculants will depend on the metal composition, section thickness of casting, charging materials, melting temperature, and also ladle size etc.
Some of the grades are given below…
It is a highly effective inoculants based on ferrosilicon for grey and ductile cast iron. The elements barium, aluminium and calcium give the alloy an excellent inoculation effect over a wide range of applications. It is used for Grey Cast Iron & S. G. Iron.
Si :- 65-70%, Ba :- 2-2.5%, Ca :- 1.0-1.5%, Al :- 1.0-1.5%.
It is available in grain size 1-3mm, 3-6mm & 0.2-0.7mm.
0.3-0.4% for ladle inoculation & 0.05% for Mould Inoculation.
Keep in dry place and away from moisture.
One year from date of manufacture.
25 kg paper bags.
It is highly effective, FeSi 75- based inoculant for Grey Cast Iron & ductile iron with a very low Aluminium & Calcium content. The inoculation effect is achieved through the Strontium content of the alloy. Using INOCUL SR in the production of ductile iron can be particularly effective when products with low Calcium & Rare Earth contents are used in the smelting, desulphurization & treatment process. It is also especially used for Cylinder Heads & Block Castings
Si :- 72-77%, Sr :- 0.8 – 1.2%, Al :- < 0.1 % , Ca :- < 0.1%
It is available in 1-3mm, 3-6mm & 0.2-0.7mm.
0.05-0.25% for ladle inoculation & 0.05% for Mould Inoculation.
Keep in dry place and away from moisture.
One year from date of manufacture.
