Abstract

The invention relates to a high-precision weldless iridium crucible and a manufacturing method of iridium products, wherein a processing method of sheet spinning formation is used for directly spinning an iridium sheet to form an integrated weldless iridium crucible; and the problem that high precision requirement of iridium crucible and iridium products cannot be reached for reason of casting process and welding process is solved. By the method disclosed by the invention, the high-precision iridium crucible and iridium products with diameter less than 100 mm can be produced; the boundary dimension deviation and thickness deviation can be 0.02 mm.

Description

technical field [0001] The invention relates to the field of iridium crucible manufacturing, in particular to a method for manufacturing a high-precision non-welded iridium crucible. Background technique [0002] Due to the high density of metal iridium (22.56g / cm 3 ), high melting point (2454°C), high temperature resistance, high hardness, high strength and acid and alkali corrosion resistance. Especially with the rapid development of the aerospace industry, the demand for high-precision iridium products is increasing. [0003] At present, the processing methods of iridium crucible mainly include casting method and plastic welding method. The casting method is to heat and melt iridium powder or iridium block through an intermediate frequency induction furnace, and then directly inject iridium solution into a magnesium oxide or graphite mold to cast an iridium crucible. The process is simple, but there are many defects, the most important ones are prone to defects such as ...
