Inoculant is mainly used in casting production and is a commonly used additive to refine the grain of castings. It has stable performance, low melting point, good solubility, and allows for a low incubation temperature. The outstanding feature of inoculant is that it does not significantly increase the number of eutectic groups while reducing the white mouth, so it can reduce the shrinkage tendency and improve the compactness and water pressure resistance of the casting. When using inoculant, it must be placed in molten iron, and it can flow out with the molten iron when tapping, so in order to obtain a good pouring effect, there are very strict operating requirements for inoculant. Below, our inoculant manufacturers will give you a detailed introduction to the product advantages of inoculants.
Product advantages of inoculant: inoculant is to adjust the composition of Al and Ca to a minimum as much as possible and carry out special treatment, cast iron has good elongation and impact toughness, but the microsegregation of silicon in iron with the increase of phosphorus content, this segregation is more serious, and has a negative impact on mechanical properties, especially when the temperature is lower than zero, and low sulfur content can be used low magnesium low rare earth nodularizing agent spheroidization, and reduce the generation of "black spot" defects, low silica nodularizing agent and "black spot" is mainly magnesium, Cerium sulfide and oxide aggregates, in addition to low silica nodularizing agents to ensure that multiple inoculation can be carried out.
Inoculants have a wide range of applications and are mainly used in the production of castings such as gray cast iron and ductile iron. In conclusion, inoculants have a wide range of applications in the foundry and metallurgical industries, and are important additives to optimize casting properties and improve material quality.
