Introduction to Inoculant
Inoculants are substances used in the metallurgical industry, especially in the production of cast iron and steel. They play a crucial role in modifying the microstructure of the metal during the solidification process. By adding inoculants, the grain size of the metal can be refined, graphite morphology can be improved, and mechanical properties such as strength, toughness, and ductility can be enhanced. Inoculants also help to reduce the tendency of the metal to form defects like shrinkage cavities and porosity, thereby improving the overall quality and performance of the final cast products. There are various types of inoculants, including ferrosilicon - based, calcium - based, and rare - earth - based inoculants, each with its own unique characteristics and applications.
