HEATING VESSEL PREVENTING LEAKAGE OF HIGH TEMPERATURE METAL MATERIAL, AND MANUFACTURING METHOD THEREFOR

摘要

The present invention relates to a heating vessel preventing leakage of a high temperature metal material, and a manufacturing method therefor. The heating vessel comprises: an internal heating vessel used for accommodating a metal material, an external heating vessel used for being heated by a heating device, and an upper cover provided with an air hole for the metal material to escape after evaporating. The internal heating vessel is completely accommodated within the external heating vessel and the position of the internal heating vessel is fixed with respect to the external heating vessel. A gap is arranged between a sidewall of the internal heating vessel and a sidewall of the external heating vessel. The upper cover is fixed above the internal heating vessel and the external heating vessel to cover an opening of the internal heating vessel and the external heating vessel. Also provided is a manufacturing method for the heating vessel. The present invention overcomes the problems of abnormal loss of material and production schedule interruptions caused by cracks appearing in a heating vessel in daily use, effectively improving a continuous and stable operation cycle of a heating device, and ensuring product quality.
