Section 1: The Manufacturing Process of Hot Rolled Coils H2

Hot rolled coils are a type of steel product known for their exceptional strength and versatility. Understanding their manufacturing process is essential to appreciate their significance in various industries.

1.1 Raw Materials

The journey of hot rolled coils begins with high-quality raw materials, typically in the form of slabs or billets. These raw materials are carefully selected to ensure the final product meets the required specifications.

1.2 Heating

The slabs or billets are heated to a temperature range of 1,100°C to 1,700°C in a furnace. This high heat softens the steel, making it malleable and ready for rolling.

1.3 Rolling

Once heated, the softened steel is passed through a series of rollers, which gradually reduce its thickness while increasing its length. This process, known as rolling, gives hot-rolled coils their characteristic shape and strength.

1.4 Coiling

After the steel has been rolled to the desired thickness, it is coiled into large rolls. These coils can vary in size, with some reaching several tons in weight.

1.5 Cooling

To temper the steel and improve its properties, the coils are cooled slowly in a controlled environment. This process, called controlled cooling, helps in achieving the desired mechanical and metallurgical properties.
