Hot rolled coil

Hot rolled coils, also known as hot rolled coil or HRC, is a type of steel sheet or plate that has been processed at a temperature above its recrystallization temperature. A hot rolled coil is typically measured by its thickness, width, weight and by its specific weight as well. The HRC product is available in a variety of grades, ranging from medium-to-high strength steel.

The hot rolled coil process begins with heating of the strip steel to a particular temperature, often around 700 to 900 °C. The strip is then cooled by passing it through a series of cooling rolls. During the rolling process the strip is either annealed or recrystallized depending on the grade of material. The HRC process results in a thicker and flatter material than a cold rolled product.

HRC can be used in a variety of applications, from automotive components and home appliances, to construction and shipbuilding. The majority of hot rolled coil products are used in auto body parts, such as fuel tanks, wheel wells, grills and doors. The hot rolled coil also has several advantages over cold-rolled materials, such as increased strength, greater ductility and reduced risk of corrosion.

Since the hot rolled coil is stronger than cold rolled steel, it has a greater capacity to carry loads—allowing manufacturers to reduce their cost of production. Additionally, hot rolled coils do not need to be treated as much as cold-rolled materials, which results in lower costs for both maintenance and labour. As a result, the HRC process can provide an economical solution for production of flat rolled steel products.

In addition, the HRC process offers several other potential benefits for the end user. For example, hot rolled coils provide a smoother surface than cold-rolled material that can be painted more effectively. The large flat surfaces offer more aesthetic appeal and can therefore be used more effectively in applications where aesthetics are important. The hybrid product can also be used in applications that require extra strength, as well as in applications that use lighter gauges of steel.

Overall, the hot rolled coil process is an efficient and economical way for steel manufacturers to produce flat rolled steel products. The HRC provides greater strength, ductility and a range of grades that can be used in a variety of applications. Whether it’s automotive components or construction projects, the hot rolled coil process can provide an ideal solution for your steel needs.

Hot Rolled Coil (HRC) is a flat rolled rolled coil steel product generally available in thicknesses of 1.0 mm to 4.0 mm and widths of 700mm to 2000mm. Hot Rolled Coil is carried out at temperatures above the recrystallization temperature of the steel to produce formations of planes, spheres and straight lines on the steels surface. Hot Rolled Coil is one of the most economical metals in the world and is widely used in many applications.

The production process of hot rolled coil includes cogging and cooling the slab, or starting slab, on a hot strip mill coil running line. The slab is heated in a furnace that uses either natural gas or electricity as an energy source before it is rolled through a hot strip mill.

Hot Rolled Coil products are produced with improved surface roughness and reduced thickness deviation, also known as pickling. Depending on applications, Hot Rolled Coil may need to be surface treated to receive a desired product characteristic. Common Hot Rolled Coil treatments include pickling, product brushing, painted and multi-coat finishes, and this hot rolled metal is often pre-stressed to increase the tensile strength of the metal.

Hot Rolled Coil is an inexpensive and versatile material used commonly in the construction of machinery, appliances, household goods, transport vehicles, and many other products. It is commonly used in automotive, shipbuilding and construction industries. Its mechanical properties are superior compared to other structural materials with superior corrosion resistance. Hot Rolled Coil is generally easier to process compared to cold rolled steel and assists in reducing manufacturing costs due to which it is widely used in production. Hot Rolled Coil can be magnetised and cold drawn to form.
