Product Introduction

Steel billets are key semi-finished products in the steelmaking process. They are made by smelting molten iron in a converter and then casting it through a continuous casting process. They are the original materials for rolling various types of steel. There are many types of steel billets. According to their chemical composition, they can be divided into low-carbon steel billets, alloy steel billets, etc.; according to their cross-sectional shapes, they include square billets, slabs, round billets, etc. The production of steel billets requires strict control of smelting temperature, composition uniformity, and inclusion content to ensure the mechanical properties and processing properties of the finished steel. As the core link of the steel industry chain, steel billets are widely used in construction, machinery manufacturing, automotive industry and other fields, and their quality directly affects the service life and market competitiveness of subsequent steel products.

Steel Blillet Benefits

1. Basicity and plasticity: Steel billet is the basic material for making steel products. Through hot rolling, cold rolling, forging, drawing and other processing techniques, steel products of various specifications can be produced, such as steel plates, steel pipes, steel coils, etc. This high degree of plasticity makes steel billets have broad application prospects in industrial production.

2. Excellent mechanical properties: Hot-rolled steel billets are produced through hot-rolling processes at high temperatures and have high strength and hardness while maintaining good plasticity and toughness. This makes hot-rolled steel billets excellent at withstanding heavy loads and impacts, making them suitable for manufacturing a variety of structural and mechanical parts.

3. Energy saving and environmental protection: Modern billet rolling technology realizes the continuity of continuous steel casting and rolling processes, and can make full use of the waste heat of continuous casting billets for rolling, thus saving a lot of energy. Compared with the traditional multi-fire forming process, this new process can significantly reduce energy consumption and increase the yield rate.

4. Improve production efficiency: The adoption of billet rolling technology simplifies the production process, reduces the number of repeated heating times and cooling time, thereby shortening the production cycle and improving production efficiency. At the same time, it also reduces the area occupied by equipment and factory buildings, reducing infrastructure investment and production costs.

5. Good processing performance: The steel billet forms a uniform structure and high purity during the rolling process, which makes it show good processability in subsequent processing. Whether it is cutting, welding or forging, you can get satisfactory results.

Steel Billet Applications

1. Construction field: Hot-rolled steel billets can be used to manufacture various building structural materials, such as steel beams, steel columns, steel frames, etc. Due to their high strength and excellent mechanical properties, these structural materials excel in withstanding heavy loads and resisting earthquakes.

2. Machinery manufacturing field: Steel billet is one of the important raw materials in the machinery manufacturing industry. Various mechanical parts and components, such as gears, bearings, shafts, etc., can be made through forging, rolling and other processes. These parts play a key role in the operation of mechanical equipment.

3. Energy field: In the energy field, steel billets are widely used in pipeline manufacturing in oil, natural gas and other industries. Hot-rolled steel billets can be made into various steel pipe products through cold rolling, drawing and other processes, such as seamless steel pipes, welded steel pipes, etc. These steel pipe products exhibit good corrosion resistance and pressure-bearing capabilities when transporting oil and gas resources.

4. Transportation field: Steel billet is also one of the important raw materials in the transportation industry. It can be used to manufacture body structures and components for vehicles such as cars, trains, and ships. At the same time, in railway construction, steel billets are also used to manufacture key facilities such as rails and switches.

5. Other fields: In addition to the above fields, steel billets are also widely used in electronics, home appliances, military industry and other fields. In these fields, steel billets are mainly used to manufacture various parts and components to meet different use structural requirements.
