Beschreibung
Zusammenfassung:	The invention provides a high-temperature uniformly preheating structure and method for powder in a sealed cavity. The high-temperature uniformly preheating structure structurally comprises a fixed base unit and a high-temperature radiation heating unit, wherein the high-temperature radiation heating unit comprises a radiation heating housing; the high-temperature radiation heating unit can move left and right; a left radiation heating component is hinged to the left side of the radiation heating housing; a right radiation heating component is hinged to the right side of the radiation heatinghousing; and the left radiation heating component and the right radiation heating component are symmetrically arranged left and right, and can move relative to the radiation heating housing to adjustthe radiation range. The high-temperature uniformly preheating structure has the advantages that 1) the longitudinal position, the horizontal position and the power of the heating structure can be adjusted according to the hea
