Abstract

PURPOSE:To increase strength of a containr of specified size and prolong its life by applying both press drawing and spinning to a difficultly weldable metallic material of specified thickness. CONSTITUTION:A difficultly weldable metallic material 10 such as molybdenum having the thickness of 1-3mm. is set in a die and heated. A punch 24 is lowered by a hydraulic press and press drawing work is made. The semi-worked material is removed from the die as it is attached to the punch 24. The punch 24 is held by a lathe chuck 31 and the semi-worked material 10' is fixed. The semi-worked material 10' is heated by a burner etc. while rotating the material by the lathe chuck, and spinning is made by a roller 36. The finished semi-worked material 10' is made to a dish-shaped boat having the size of 50-250mm. in outer diameter and 5-50mm. in height.
