Steel billets undergo a process known as hot rolling to shape them. This involves heating the billets to high temperatures above 1,000 degrees Celsius to make them malleable and easier to shape. The heated billets are then passed through rolling mills, which consist of rotating cylindrical rollers.
As the billets pass through the rollers, they are gradually compressed and elongated, resulting in the desired shape and size. The pressure applied by the rollers reduces the billets' thickness and increases their length. This continuous rolling process allows for precise control over the shape and dimensions of the steel product.
To ensure smooth rolling and prevent the billets from sticking to the rollers, lubricants are commonly used. These lubricants also help dissipate the heat generated during rolling.
Depending on the desired final product, the billets may undergo multiple passes through the rolling mills to achieve the desired shape and dimensions. After the initial rough rolling, further shaping and refining may be done through additional rolling stages.
Once the desired shape is achieved, the steel is allowed to cool and solidify. This cooling process is crucial to ensure the final product possesses the desired mechanical properties and structural integrity.
In summary, the hot rolling process of steel billets plays a vital role in the production of various steel products. It enables efficient shaping and forming of the billets into different shapes, sizes, and profiles, meeting the specific requirements of industries like construction, automotive, and manufacturing.
Steel billets are rolled into shape through a process called hot rolling. This process involves heating the steel billet to high temperatures, typically above 1,000 degrees Celsius, to make it malleable and easier to shape. The heated billet is then passed through a series of rolling mills, which consist of a pair of cylindrical rollers that rotate in opposite directions.
As the billet passes through the rollers, it is gradually compressed and elongated, resulting in a desired shape and size. The rollers apply high pressure on the billet, effectively reducing its thickness and increasing its length. This continuous rolling process allows for precise control over the shape and dimensions of the steel product.

Steel billets are rolled into shape by passing them through a series of rolling mills, where they are subjected to high pressure and temperature. The billets are first heated to a specific temperature to make them more malleable. They are then continuously passed through multiple sets of rollers, which gradually decrease the thickness and increase the length of the billet. This process, known as hot rolling, helps shape the steel billets into various forms such as bars, rods, or sheets.
