Hot-rolled application
1. It is suitable for general structural steel and engineering HR steel plate and steel strip, and can be used for welded pipes, cold-rolled materials, bicycle parts, and important welding, riveting, and bolting components.
2. Used for cold rolling and deep drawing products.
3. Making stamping and structural parts of automobiles, tractors, engineering hoisting machinery, and small light industrial civil machinery.
4. Make containers and exposed metal structures.
5. Welded pipe and steel structure.
6. Pipelines for transporting oil and gas.
7. Automobile girders and beams.
8. Special steel belt for automobile wheels.
9. Structural anti-skid plates, stairs, ladder pedals, etc.
Hot-rolled coils are made from slabs, which are heated and then rolled into strips by rough rolling mills and finishing rolling mills.
The high-temperature steel strip coming out of the finishing mill is cooled to the set temperature by laminar flow and wound into a coil by a coiler.
Finishing lines for steel plate, flat coil and slitting strip products (leveling, straightening, cross-cutting or slitting, inspection, weighing, packing and marking, etc.).
Detailed Photos
Hot-rolled steel products are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels due to their excellent properties such as high strength, high toughness, easy processing, and excellent weldability.
Therefore, there is a huge demand for HRC in the market.
What is the difference between hot and cold rolled coil?
The main difference between hot and cold rolled steel is in how they are processed. Hot rolled steel is steel that has been rolled at high temperatures, while cold rolled steel is essentially hot rolled steel that is further processed in cold reduction materials.
What is hot rolling used for?
Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal.
What are the three types of hot rolled steel?
Hot rolled steel grades are classified into the following carbon groups:
- Low-carbon or mild steel contains 0.3 % or less carbon by volume.
- Medium-carbon steel contains 0.3% to 0.6% carbon.
- High-carbon steels contain more than 0.6% carbon.
Application
Hot-rolled coil is the raw material for almost all steel products, such as cold-rolled coil, galvanized coil, pre-painted coil, angle steel, H Beam, flat steel, steel pipe, etc.And it widly used in color scroll raw material,building base material,boiler and the base material of the profile.It can be divided into ordinary carbon plate, excellent carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate, etc. Hard-rolled coils: Continuous rolling of hot-rolled pickled coils at room temperature.
Hot rolled steel plate products include steel strip or coil and steel plate cut from it. The steel strip or coil can be divided into straight roll and finishing roll (sub-roll, flat roll and slitting roll).

Features of hot rolling:
1. Low energy consumption, good plastic processing, low deformation resistance, no obvious work hardening, easy rolling, and reduced energy consumption required for metal deformation.
2. Hot rolling usually uses large ingots and large reductions for rolling. The production rhythm is fast and the output is large, which creates conditions for large-scale production.
3. The as-cast structure is transformed into a processed structure through hot rolling, and the plasticity of the material is greatly improved through the transformation of the structure.
4. The characteristics of the rolling method determine that there is anisotropy in the properties of the rolled sheet. First, there are obvious performance differences in the longitudinal, transverse and high directions of the material. Second, there are deformation textures and recrystallization textures. There is an obvious directionality in control performance.
