What is hot rolled steel coil?

Summary

Hot rolled coil is a steel plate made from slabs that are heated and rolled by roughing and finishing units. The hot rolled steel strip from the last mill of the finishing mill is cooled to the set temperature by laminar flow and then coiled into steel strip coils by the coiling machine. The cooled steel strip coils are processed into steel plates, flat coils and longitudinal cut steel strip products through different finishing lines (flattening, straightening, cross-cutting or longitudinal cutting, inspecting, weighing, packaging and marking, etc.) according to the different needs of the users.

Hot Rolled Steel Coil

China is the world's largest producer, consumer and exporter of hot-rolled steel, with output reaching 232 million tons in 2015. The development of the iron and steel industry has effectively supported the steady and rapid development of China's national economy, and the improvement in the output and quality of hot rolled coil plate has also better meet the growing practical demand of China's construction, machinery manufacturing and other industries.

Categorization

Hot rolled steel in coil generally includes medium-thickness wide steel strips, hot rolled thin wide steel strips and hot rolled thin plates.

The medium-thickness wide steel strip is one of the most representative varieties, its production accounted for about two-thirds of the total output of hot rolled coil, the Shanghai Futures Exchange will soon be listed in the hot rolled coil futures contract underlying belongs to the medium-thickness wide steel strip.

Hot Rolled Steel Coil

Medium-thick and wide steel strip means steel strip with a thickness of ≥3 mm and less than 20 mm and a width of ≥600 mm, produced in continuous broad strip steel hot rolling mills or furnace coil rolling mills or other equipment, and delivered in coils.

Hot-rolled thin and wide strip means steel strip, of a thickness of <3mm and a width of ≥600mm, produced in continuous broad strip mills or furnace rolling mills or thin slab mills, etc., and delivered in coils.

Hot rolled sheet means a single sheet of steel with a thickness of <3 mm. Hot rolled sheet is usually produced in continuous broad strip mills, continuous casting and rolling of thin slabs, etc., and delivered in sheet form.

Production capacity

In 2023, steel plate hot rolled nearly two decades since the production capacity of production increased mode, as of the end of 2023, hot rolled steel sheet in coils production reached 291,255,600 tons, a production growth rate of 11.01%. 2023 hot rolled coil steel production more than rebar (2023 production of 260 million tons), jumped to China's first major steel varieties.

On the trend of annual production changes, in the past five years, the production of hot rolled sheet and coil showed a year-on-year increase in the situation, and the growth rate from 2.57% in 2019, increased to 11.01% in 2023, the growth rate increased by 8.51 percentage points.

Monthly production of the hot rolled coiled steel in 2023 is above the highest level in history. Due to the production growth rate of 11.01% in 2023, far exceeding the capacity growth rate of 3%, the hot rolled coil steel mill capacity utilization rate increased to 84.7%, 6.11 percentage points higher than in 2022. This shows that the market high production mode basically throughout the year.

Applications

1.  Building structures: Hot rolled steel coils are commonly used as a material for building structures, such as steel, aluminium and galvanized steel sheets used to make roofs, walls and floors. These materials usually have high strength and corrosion resistance and can meet the needs of buildings in a variety of environmental conditions.

2.  Automobile manufacturing: Automobiles are another major application area for HRC coils. They are used to make components such as car bodies, doors, hoods, roofs and chassis. The automotive industry has very strict requirements for materials with high strength, rigidity and corrosion resistance, all of which are characteristics of hot rolled coil.

3.  Home appliance manufacturing: Many household appliances, such as refrigerators, washing machines, microwave ovens and air conditioners, require the use of hot rolled coil as a structural material. These materials usually need to have a good surface finish, as well as high mechanical properties and corrosion resistance.

4.  Luggage manufacturing: some luggage products, such as aluminium boxes, luggage, luggage shells, etc., also commonly use hot rolled coil as a material. Hot rolled coil is a lightweight, strong structure, and can meet the luggage products on the lightness and strength of the material needs.

5.  Machinery manufacturing: in the machinery manufacturing industry, hot rolled coil is widely used in the manufacture of machinery and equipment parts, such as racks, support frames, sliders, rails and so on. These parts need to have high strength and wear resistance, and HRC coils are able to meet these requirements.
