The production of metal structures of various sizes and purposes is carried out using rolled metal, which is usually classified, including by its geometric shape. So, a channel, hot-rolled UPE or UPN (format with parallel or sloped inner edges of the shelves) U-shaped :
- Works great in flexural design.
- Can handle axial loads without compromising structural integrity.
Is a fairly affordable product at cost, widely used in construction, as well as in various industries and mechanical engineering.
Equipment and manufacturing technology
Hot-rolled channels are made using section or rail-and-beam machines. A rectangular beam made of low-carbon or carbon steel grade is used as a workpiece. The so-called compression of the incandescent beam to give it the U-shape of the final product with the given parameters (dimensions) of the section can be carried out in several ways:
- Beam - reduction is carried out according to rough dimensions using a small number of squeezing rolls and re-rolls, which greatly simplifies the manufacturing procedure, but allows deviations in the dimensions of the profile relative to its length.
- With an increased release - the rough (initial) dimensions of the calibers through which the beam is pulled to give it the configuration of the channel are specially increased. This helps to reduce wear on equipment (feed rolls) and improve workmanship (adherence to specified dimensions).
- With extended shelves - allows you to make a channel that meets the GOST parameters using a smaller number of running rolls.
If it is necessary to give the channel a configuration bent along its length, use the method of cold deformation on special bending equipment.
