Description
The direct strip casting process has attracted attention as a near net shape technologies. BAOSTEEL GROUP CORPORATION and Primetals Technologies Japan, Ltd. have jointly developed technologies for the direct strip casting process of carbon steel. The demo plant for the direct strip casting process, with 800 mm diameter and 1340 mm long casting rolls, was installed in China and its operation was started up in 2014. A stable casting and rolling of 1340 mm wide strips and long term sequence casting of more than 350 ton were succeeded. This paper presents specific technologies for the downstream equipment of the direct strip casting process such as an in-line reduction mill, strip cooling system and carrousel reel type coiler. Our discussion focuses on stable rolling technologies including technologies of the Dynamic Pair Cross Mill and strip temperature control.
