In the metal forming industry, metal rolling processes constitute a very important place. There are two types of metal rolling processes; the first one is the flat metal rolling process. In flat metal rolling processes, metal parts are formed into flat shapes such as strips, slabs, sheets, etc.
The other type of metal rolling process is the shape metal rolling process. Here we explain the general characteristics of shape metal rolling processes.
The difference in the shape metal rolling process is the shape of the final products. The produced final shapes are not flat generally. They are produced in intended shapes such as rail cross-section, I-beam cross-section, etc. Bars, rods, different railroad tracks are the products of the shape metal rolling process.
The design of the required shape rolling machinery is very important. Obtaining the required cross-section with one set of rolls is not possible. You need to design the required rolling process with sets of rolls, in which there must be a smooth transition between cross-sections, from starting to end. This design process is called a roll-pass design.
This roll-pass design principle was important because of the uniform shaping of the metal cross-section. The starting cross-section of the metal billet is generally rectangular.
Warping and cracking of the work part are the general problems if the roll-pass design is not embraced.
This can be general information about the shaped metal rolling processes.
