Metallurgical chemicals are essential in the treatment and processing of metals, enabling their production, refinement, and enhancement. They alter metal properties to meet specific requirements, ensuring durability, strength, and corrosion resistance. Key metallurgical chemicals include fluxes, deoxidizers, alloying agents, modifiers, desulfurizers, inoculants, grain refiners, cleaning agents, corrosion inhibitors, and heat treatment chemicals. These chemicals help in achieving desired mechanical properties and microstructures in metals, ensuring their durability and resistance to corrosion.
