Inoculant (Inoculum)

Time 2016-12-29 | View 151

 

Nucleating agent, also referred as Inoculant, is a kind of additive which can refine grain and improve the mechanical properties and processing properties. It can improve the shape and distribution of graphite, increase the number of eutectic nucleus, slow down the recession of nodulizing, eliminate and prevent the casting chilling tendency and reduce section sensitivity. Adding the nucleating agent into the spheroidized molten iron will increase the number of graphite spheres, eliminate cementite and enhance plasticity and toughness.

It is mainly applied in deoxidizer, desulfurization agent, reducing agent, addition agent, alloy agent, temperature-increasing agent for steel melting and foundry, as well as the nucleating agent, inoculating agent and vermiculating agent for cast iron or magnesium treatment of nodular cast iron. It is applicable for inoculation in all castings.

Varieties of products are offered in our company and they are well designed and enjoy effective inoculation. They also can help realize inoculation in high-grade castings with good effects. This series of products includes silicon barium, silicon strontium, silicon zirconium, high-aluminum cubic ferrosilicon, long-acting and special-effect inoculants, Inoculant chips and so on.

Remarks: Various specifications of products are available as customers demand.

Product Features & Functions: 

◆The elements of the product are evenly distributed and the deviation of its main elements is small.

◆It enjoys well-balanced particle-sizes, precision screening, and purity.

◆It well eliminates or alleviates chilling tendency.

◆It avoids under-cooling .

◆It effectively alleviates the sensibility to the thickness of the iron castings, so that there are small differences between the particles in thick section and thin section, and in toughness as well.

◆It is beneficial to nucleation of eutectic cells, and increases their numbers.

◆It helps smooth the graphite shape so that the mechanical function of the castings is improved;

◆Adding the nucleating agent into the spheroidized molten iron will increase the number of graphite spheres, and eliminate cementite and enhance plasticity and toughness of the product.

Packaging: Supplied in 25Kg woven bags of plastic liners, or craft paper bags or in 1-ton bag package. Various specifications of the product are available as customers demand.
