Exothermic Risers/ Sleeves
Exothermic Risers/ Sleeves are specialized materials engineered to generate heat through exothermic reactions, serving critical functions in the metallurgical industry, particularly in the casting of metals. These materials, often in the form of riser sleeves or feeding systems, contain carefully formulated mixtures of reactive agents that release heat when activated by contact with molten metal. By providing localized heat sources, exothermic goods facilitate uniform solidification of metal, reducing the risk of defects such as shrinkage and porosity in castings, thereby enhancing product quality and manufacturing efficiency.
