| Abstract: | In this paper a type of basic tundish covering flux has been developed according to the phase diagram of CaO-SiO2-Al2O3. The capacity of absorbing Al2O3 inclusions of the fulx as well as those of acid and neutral tundish covering fluxes was experimentally studied, and it is found that the basic tundish covering flux has greater capacity of absorbing Al2O3 inclusions. The industrial test has also proved that the basic tundish covering flux is of good metallurgical effects. |
