Surface
Hot rolled steel is steel that has been roll-pressed at very high
temperatures—over 1,700, which is above the re-crystallization
temperature for most steels. This makes the steel easier to form,
and resulting in products that are easier to work with. To process
hot rolled steel, manufacturers first start with a large,
rectangular length of metal, called a billet. The billet is heated
and then sent for pre-processing, where it is flattened into a
large roll. From there, it is kept at a high temperature and run
through a series of rollers to achieve its finished dimensions.
Steel shrinks slightly as it cools. Since hot rolled steel is
cooled after processing, there is less control over its final
shape, making it less suitable for precision applications. Hot
rolled steel is often used in applications where minutely specific
dimensions aren't crucial.Hot-rolled steel and sheet metal products are commonly used for
industrial applications worldwide. With a wide range of options, HR
plate and sheet metal products provide numerous advantages that
other metal products cannot replicate.

Carbon steel manufacturing process:
The smelting of carbon steel is usually carried out in converter
and open hearth. Converters generally smelt ordinary carbon steel,
while open furnaces smelt all kinds of high-quality steel. The
technology of oxygen top blow converter is developing rapidly and
it can replace open hearth furnace. The refined liquid steel is
injected into the ingot mold to obtain various ingot. After the
ingot is forged or rolled, it is processed into plates, strips,
bars, and sections of various sectional shapes. Carbon steel is
usually used directly in the hot rolled state. When used for
manufacturing tools and various machine parts, it needs to be heat
treated according to the requirements of use; As for steel
castings, most of them are heat-treated.
Steel Sheet Application :
1. Construction field: Carbon steel plates are often used in the
manufacture of building structures, such as steel frames, steel
beams, etc. Due to the high strength and plasticity of carbon steel
plate, it can withstand large loads, so the widely used in
construction.
2. Automobile manufacturing: carbon steel plate is an important
material for manufacturing automobile body and frame. carbon steel
tool It has good plasticity and welding performance, which can meet
the requirements of automobile manufacturing.
3. Home appliance manufacturing: Carbon steel plates are often used
in the manufacture of home appliances, such as refrigerators and
washing machines.The carbon steel plate can be made into parts of
different shapes through the stamping process to meet the needs of
home appliances need.
4. Shipbuilding: Carbon steel plates are also widely used in
shipbuilding. Due to the carbon steel tool Good plasticity and
welding performance can meet the requirements of ship structure.
5. In other fields, carbon steel plates are also widely used in
machinery manufacturing, petrochemical, metallurgy and other
fields. area.
Steel Sheet Characteristic:
1. High strength: carbon steel plate has high strength, which can
meet the needs of various structures. which is high Carbon steel plate has the
highest strength, but poor toughness, and is suitable for occasions
requiring high strength.
2. Good plasticity: carbon steel plate has good plasticity, and can
be processed by cold processing and hot processing Forming and processing in different ways to meet the
needs of different shapes.
3. Good welding performance: carbon steel plate is easy to weld,
and multiple carbon steel plates can be welded by welding process
The steel plates are joined to form structures of larger
dimensions.
4. Poor corrosion resistance: carbon steel plates are prone to rust
in humid environments and require anti-corrosion treatment management to prolong the service
life
