Rolled metal today is manufactured in a wide range. This category hides several types of products at once, differing in shape, size, scope, thickness, composition, etc.
At the same time, all types of rolled metal are divided into two main categories, based on the technology of their production: cold rolling and hot rolling of metal. Its properties, ability to withstand the load, service life, etc. will depend on the method by which rolled metal was produced.
Below we will understand in detail what the concept of hot-rolled metal products implies, where it is used and how it happens.
Features and properties of hot rolled metal
How does the principle of production of metal products affect their characteristics and properties? Directly. Let's take a look at hot-rolled steel. Such rolled metal products are manufactured under the influence of elevated temperatures, which affect the very structure of the base. This allows you to give parts more plasticity and elasticity. As a result, working with rolled metal becomes much easier. And this means that the scope of its application is significantly expanding.
Typically, manufacturers use several types of steel: alloy or carbon. If we compare externally the parts with analogs made by the method of cold rolling of metal, we can note the difference in angles - they are more round.
The production process is carried out at a temperature of about 1000°C. The workpiece becomes more plastic. Even large sheets can be used for production. At the same time, the main advantage of such rolled metal is its lower cost compared to analogues of cold rolling.
They also have a drawback: it is better not to mention the attractiveness of the appearance of hot-rolled steel. Sheets do not look quite neat, may have minor defects.
What is hot rolled metal and where is it used
Types of hot-rolled metal products are distinguished based on several product features:
- Thickness. According to this criterion, sheets are produced in two categories: thin (up to 4 mm thick) and thick, the thickness of which can reach 16 cm.
- Accuracy. This indicator is difficult to achieve by hot rolling of metal. At the same time, sheets are of increased accuracy (they are marked with the letter A) and normal accuracy (B).
Additionally, hot-rolled metal can be coated with various compositions:
- paint coatings;
- organosol coating;
- plastisol coating.
All of these options are usually indicated on the label.
The use of hot rolled metal products is not limited to one industry. It is used in the following areas:
- With construction. Due to the fact that hot rolling makes it possible to process huge sheet sizes, finished rolled metal is used in the construction of buildings and the construction of bridges.
- Automotive. Hot-rolled rolled metal is used for seat frames, as well as individual elements of a car engine.
- Decoration and construction of additional elements. This includes stairs, fences and other types of fences, railings.
Stainless steel is actively used in many areas of production: construction, engineering, food / chemical industry, and so on. Here https://ukrstarline.ua/en/nerzhaveyushchiy-metalloprokat you can learn more about the entire range belonging to the category of hot-rolled metal products.
