Laminate it’s a adjective that is used to qualify that which is endowed with plates. The concept also refers to act and result of laminating: make sheets or garnish something with this type of plates.
To understand what a laminate is, we must first focus on the idea of sheet. This is the name of a thin piece, flat and usually metallic.
In its most common use, the notion of laminate refers to a coating of various strata. Laminate is usually made up of three layers: a lower layer that functions as a moisture barrier, an intermediate layer of greater thickness that acts as a substrate, and an upper layer that is the finish of the material.
Laminate can be used to cover the floor or the wall. The goal is that this product It is decorative thanks to its aesthetics, but also provides a series of benefits (such as preventing the passage of moisture, to name one of its advantages).
The laminating process or laminationon the other hand, it is carried out to reduce the thickness of a sheet of metal or a similar material that is malleable. To develop this laminate, it is usually applied Pressure with a device known as laminator.
Lamination is done hot or cold, depending on the case. The plate must continuously pass through cylinders that generate the compression forces and that cause the deformation plastic of the material.
In general, hot rolling represents the first phase of the process by which molten materials are transformed into final products, and it is possible to make significant section reductions. We must ensure that the temperature of the metal mass rises uniformly until it reaches the desired point before it begins to deform, to avoid problems such as breakage or cracking.
Among the finished products that are usually generated by hot rolling, bars, rounds, strips and sheets stand out. Once obtained, they are used in operations machining or cold forming.
By means of cold rolling it is possible to obtain completely finished pieces, with mechanical characteristics and a very even texture. Unlike hot rolling, considerable section reductions cannot be generated.
The steel laminateIn this framework, it is one that undergoes a process of this kind. The iron and carbon alloy is melted into ingots that are rolled to the desired measurements.
It is common to carry out the laminating process in what is known as rolling mill, a series of roller units that are chained and act on the metal until the product is finished. These trains They are classified as follows:
* roughing: they are used to grind ingots hot with the aim of converting them into billets or pouches, depending on the needs. The thickness and width of the pieces obtained are in a range of 130-140 and 130-550 millimeters, respectively;
* billet: they are used for the rolling of the slab that is obtained by the previous trains and turn it into products of square or rectangular section, which are known as billets and plantains, respectively;
* Finishing: the finished products are obtained taking as a starting point those that arise from the previous train. Depending on the shape of the cylinders from the finishing trains, it is possible to obtain different parts. For example, the results will vary if they are smooth or ribbed.
Thanks to profile rolling It is possible to produce contours in the cross section to give rise to various shapes. For this, the material is passed through rollers with the printed form.
