Flame straightening
WebMar 20, 2010 · The proposed types of heat straightening method used largely depending on the situation type and extend of distortion in steel structure. In case of beams and bulkhead straightening the single flame is most commonly used. For straightening large areas such as deck plating, the multi-flame line will be used to obtain effective … WebFlame straightening is classified as a mechanical process because the resulting expansion causes external forces to impact on the workpiece which then produce stresses in the component. Plastic deformation takes place in the workpiece above the elastic limit. The result is irreversible deformation.
