[0002] Exothermic riser refers to the supplementary part added to the casting to avoid defects in the casting, and also has the functions of exhaust and slag collection. The processing and production of exothermic riser requires mixing floating beads, high-alumina bauxite, aluminum powder, iron oxide, potassium fluoroaluminate, potassium nitrate, glass water, etc. into a paste-like raw material in a certain proportion, and then filling the paste-like raw material into the preparation mold, and introducing carbon dioxide into the preparation mold to react with the paste-like raw material to harden and form.
