Straightening shells by thermal stretching

  • A. I. Krivko
Technical Information


Annealing of shells on straighteners with adjustable segments with independent sources of radial force occurring because of the difference in the expansion coefficients of the materials in the device reduces the ellipticity of thick-walled shells of steel Kh18N9T and permits smaller tolerances.
