HEATING VESSEL FOR PREVENTING LEAKAGE OF HIGH TEMPERATURE METAL MATERIAL AND MANUFACTURE METHOD THEREOF

摘要

The present invention is related with a heating vessel for preventing leakage of high temperature metal material and a manufacture method thereof. The heating vessel comprises: an internal heating vessel employed for containing metal material, an external heating vessel employed to be heated by a heating apparatus and a top cap having a vapor hole employed for escape of the vaporized metal material; the internal heating vessel is completely contained in the external heating vessel and positionally fixed relative to the external heating vessel, and an interspace exists between a side wall of the internal heating vessel and a side wall of the external heating vessel, and the top cap is fixed on tops of the internal heating vessel and the external heating vessel to cover opens of the internal heating vessel and the external heating vessel. The present invention also provides the manufacture method of the vessel. The present invention overcomes the issues of the material abnormal loss and production progress interruption due to the appeared fracture in daily usages. The continuous steady running period of the heating apparatus is effectively promoted and the quality of the production is guaranteed.
