Title: Innovations of Dexiang Cai in Continuous Casting Mold Flux
Introduction
Dexiang Cai is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of metallurgy, particularly in the development of fluoride-free continuous casting mold fluxes. With a total of 2 patents, his work has been instrumental in advancing low-carbon and ultralow-carbon steel production.
Latest Patents
Cai's latest patents include two innovative formulations for continuous casting mold flux. The first patent focuses on a fluoride-free continuous casting mold flux for low-carbon steel. This invention comprises a specific weight percentage of various components, including NaO, MgO, MnO, BO, AlO, LiO, C, and the balance of CaO and SiO, with a melting point of 95-1150°C. The mold flux has a viscosity at 1300°C of 0.1-0.3 Pa·s and a crystallization rate of 10-50%. This formulation has been successfully applied in a low-carbon steel slab conticaster, achieving a metallurgical effect comparable to traditional fluoride-containing fluxes.
The second patent pertains to a fluoride-free continuous casting mold flux for ultralow-carbon steel. This formulation includes components such as NaO, LiO, MgO, MnO, BaO, AlO, and impurities, with a melting point of 1100-1200°C and a viscosity of 0.2-0.6 Pa·s at 1300°C. The preparation method involves mixing raw materials, pre-melting, and adding a carbonaceous material to achieve the desired composition. This mold flux effectively reduces inclusion defects in blank casting and increases yield.
