Facts about the manufacturing and benefits of Hot-rolled steel:
Hit rolled steel is a steel that you roll press at a very high temperature of over 1,700˚F. It is generally above the re-crystallization temperature for most of the steels. This process makes the steel very easy to form and that results in product with which you can easily work. Before knowing about the steel rate in India, you should know about the process of hot-rolled steel and should be aware of the fact that it is cheaper than the cold rolled one.
We know that manufacturing the hot-rolled steel is not an
easy task and so we are here to explain you the process. The manufacturers
begin the process by heating the billet (a large rectangular length of metal)
and then sending it for pre-processing where it gets compacted into a large
roll. After that, the manufacturers keep that at a high temperature and run it
through a full series of rollers so that they attain its finished dimensions.
Then, they push the white-hot strands of steel at a very high speed. For sheet
metal, they spun the rolled steel into coils and leave them for cooling. To
process other forms of steel like plates or bars, they section and pack the
materials.
The steel will shrink as it cools. Since they process the
hot-rolled steel after processing, there is limited control over its final
shape that makes it incompatible for precision application. The hot-rolled
steel is often used in the applications where you do not require any specific
dimensions. The hot-rolled steel is often used in the construction projects and
railroad tracks.
The paybacks of opting for hot-rolled steel?
Hot-rolled steel does not require much processing in
comparison to cold rolled steel and this is the reason that it is cheaper. You cool
the hot-rolled steel at a room temperature and so it’s basically normalized. It
connotes that the hot-rolled steel gets unrestricted from internal stress at
the time of work-hardening process.
You can opt for hot-rolled steel where the dimensional tolerance
is not required as surface finish and material strength is not a key concern.
If surface finish matters, scaling can be rem9ved by sand blasting, grinding,
or acid-bath pickling. Once they remove the scaling, they can apply various
mirror or brush finishes. The descaled steel also provides good surface for
surface coatings and paintings.
