Semi-sealed cooling type continuous casting machine

The utility model discloses a casting machine used for metallurgy industry, particularly a semi-sealed cooling type continuous casting machine. The utility model comprises a drive sprocket which is arranged on a machine frame, a driven sprocket, chains which are arranged on the drive sprocket and the driven sprocket, and moulds which are arranged on the chains. The utility model is characterized in that a protective cover is fixedly arranged above the mould which is fixed on the chain, a jetting device used for jetting protective gas or protective powder is arranged in the protective cover, and a cooling device used for cooling the moulds is arranged between an upper and a lower chains. The jetting device can effectively inhibit metal from oxidizing when the metal is converted into solid from liquid, the cooling device used for cooling the mould can cause the mould to be cooled as soon as possible after the mould is demoulded, which is favorable for enhancing the cooling speed of metal liquid in the moulds, and the moulds are easy to demould; therefore, the work efficiency of the continuous casting machine can be effectively enhanced. The utility model with simple and reasonable structure is especially suitable for continuously casting reactive metal, such as magnesium, etc.
