本发明提供一种石墨复合铸型及铜铬系合金水平连铸工艺，属于金属材料制备加工技术领域。该设备包括熔炼系统、金属液保温系统、水平连铸系统和辅助系统。合金在熔炼系统中熔化后，经导流管进入金属液保温系统中保温；当保温炉的温度与铸型加热段的温度达到设定值后，开启水平连铸系统进行铜铬系合金棒材或板材水平连铸成形。采用本发明设计的复合铸型可有效解决铜铬系合金水平连铸过程中合金元素与石墨铸型发生反应的问题。此外，采用本发明提出的复合铸型水平连铸工艺生产铜铬系合金棒材或板材，有利于合金熔体中的夹杂物和凝固析出气体排入液相，提高合金组织致密性，进而提高合金的后续加工性能。

The invention provides a graphite composite casting mold and a horizontal continuous casting process of a copper–chromium alloy, belonging to the technical field of metal material preparation and processing. The equipment includes melting system, liquid metal heat preservation system, horizontal continuous casting system and auxiliary system. After the alloy is melted in the melting system, it is heated in the liquid metal heat preservation system through the guide pipe, open horizontal continuous casting system for horizontal continuous casting of copper-chromium alloy bars or plates. The composite casting mold designed by the invention can effectively solve the problem that the alloy element reacts with the graphite casting mold in the horizontal continuous casting process of the copper-chromium alloy. In addition, the copper–chromium alloy bar or plate is produced by the composite mold horizontal continuous casting process, which is favorable for the inclusion in the alloy melt and the gas out of solidification to be discharged into the liquid phase, and improves the compactness of the alloy structure, furthermore, the following machinability of the alloy is improved.
