| Abstract: | The effects of superheat,casting speed,secondary cooling strength on central segregation of continuous cast high-carbon steel billets were analyzed.By taking the technical measures such as:improving the cleanliness of steel,casting at near liquidus temperature,electromagnetic stiring,soft redaction and optimizing the secondary cooling are the effective way to reduce the central segregation in continuous casting high—carbon steel billets. |
| Keywords: | high-carbon steel continuous cast billet central segregation superheat |
