Description

technical field

[0001] The invention relates to the field of material forming, in particular to a method for preparing a zirconium-copper thick-walled straight cylindrical part in a cold state by strong spinning. Background technique

[0002] At present, the zirconium copper cylinder with a diameter greater than 400MM, a length greater than 2000MM, and a thickness greater than 5MM is mainly obtained by machining after forging. First, the raw material is vacuum melted and cast according to the length of the cylinder plus the process allowance to calculate the feeding weight. Qualified ingots are melted and cast for forging processing, and then the inner and outer surfaces are machined to make blanks after hot forging. Zirconium copper is a special metal with zirconium as the main alloying element, and has good thermal strength and creep resistance. , has good plasticity and electrical conductivity at high temperature, and is easy to process, and is more and more widely used i...
