| Abstract: | Soft contacted continuous casting with gas film (GFC)is investigated experimentally. The results of gas film DC casting process for aluminum show that the gas film in GFC for Al billet increases the heat resistance between metal surface and the mold inside surface. In addition, the gas film has significant influence on billet quality, and the gas backpressure increases with the gas volume increasing, and decreases with casting speed increasing. The experimental results provide an important basis for further optimizing the technological parameters of the GFC process and the structure of mold. |
