A local expert will explain the strategies used to heat straighten steel including a hands on presentation using an oxy-acetylene torch.<\/p>
Metals, like all materials, expand when heated. By using flame straightening, the technique of localized, intense heating, you can cause a small cross section of material to expand considerably and form an actual material upset, as well as the subsequent mechanical contraction of the material as it cools.<\/p>
The goal is to induce a large temperature difference between the area being heated and the surrounding, cooler metal. The contraction, or shrinking effect, is created by the temperature difference, or gradient. You are, in effect, creating the same conditions seen when welding: very hot, intense localized heating surrounded by a cooler base material.<\/p><\/div><\/div><\/td><\/tr><\/tbody><\/table><\/div><\/div><\/div>
