| Abstract: | Through the calculation of parametric analysis and bolt preload on 8MN press,the article proposes the technical solution of using the electromagnetic induction eddy current heating bolt elongation to be preloaded.Practice verifies that the technology is feasible,effective,thus providing a new idea and way to the problem that bolt can not be preload at the time when such major equipment is going through shift of relocation or technological transformation. |
