4. Annealing Following the cold rolling process, the steel strips may require annealing. This heat treatment process relieves internal stresses that develop during cold rolling, restoring ductility and reducing hardness. The annealing process can be performed in a continuous furnace where the steel strip is heated and then gradually cooled.
The scaffolding pipe straightening machine operates on a straightforward yet effective mechanism. Typically, the machine features a series of rollers and hydraulic presses that apply a uniform pressure on bent pipes. The operator feeds the bent pipe into the machine, which then automatically aligns and straightens it. Most machines are equipped with adjustable settings to accommodate various pipe sizes and materials.
