Description
Reference Price:$260/ton Mn 0.3%-0.6%
Rectangular billet continuous casting billet and mainly general carbon steel, low carbon low silicon cold-rolled material, high quality carbon structural steel, high strength low alloy steel, special steel, etc.
The billet is mainly divided into two kinds from the shape:
Slab: cross section width and height of the ratio of the larger, mainly used for rolling plate.
Billet: equal cross section width and height, or a huge difference, mainly used for rolling steel, wire rod. ,
Steel billets have distinct characteristics as compared with already furnished steel bars and products. Billets have a specific grain structure, which enables the metal to be processed more intricately. Steel billets are also known for their malleability and ductility, especially when exposed to varying temperatures during shaping and molding.
Processing of Steel Billet
Steel billets are considered fresh and raw, and they must undergo a series of manufacturing processes before they can be used for various purposes. Billets are made by means of freezing molten liquid, and are later exposed to extremely low temperatures in order to allow the metal to take shape and solidify in chemical structure. The temperature manipulates the metal's physical properties, and tones its strength and durability. The subsequent processes provide the metal's curved mold design so that it can fit the allotted space provided by other machines, which complete the finishing procedures.

- Q:What are the different heat treatment processes for steel billets?
- Steel billets can undergo various heat treatment processes, each serving a specific purpose and offering distinct advantages. Among the commonly used processes are annealing, normalizing, quenching, tempering, and case hardening. 1. Annealing: The steel billets are heated to high temperatures and gradually cooled to room temperature. This process aims to reduce hardness, enhance machinability, relieve internal stresses, and refine the grain structure, resulting in a more ductile and less brittle steel. 2. Normalizing: By heating the steel billets above the critical range and cooling them in still air, the normalizing process refines the grain structure, improves mechanical properties and machinability, relieves internal stresses, and achieves uniformity in microstructure. 3. Quenching: Rapid cooling of steel billets is achieved by immersing them in a quenching medium like oil, water, or brine. Quenching transforms the austenite phase into martensite, making the steel harder and more wear-resistant. However, it may introduce residual stresses and the risk of cracking. 4. Tempering: Following quenching, tempering is often performed to reduce brittleness and enhance toughness. The quenched steel is reheated to a lower temperature and held for a specific time period. This process relieves stresses, decreases hardness, and improves ductility without sacrificing too much strength. 5. Case Hardening: This process elevates the surface hardness of steel billets while maintaining a tough and ductile core. Carburizing and nitriding are two common methods of case hardening. Carburizing involves heating the steel in a carbon-rich environment to introduce carbon into the surface. Nitriding, on the other hand, introduces nitrogen to form a hard nitride layer. These processes enhance wear resistance and prolong the lifespan of the steel billets. These heat treatment processes allow manufacturers to customize the properties of steel billets to meet specific application requirements. By carefully selecting and implementing the appropriate process, the resulting steel billets can exhibit a wide range of mechanical properties, including hardness, strength, toughness, and wear resistance.
- Q:What are the common surface defects found in steel billets?
- Steel billets commonly exhibit surface defects, including scale, surface cracks, inclusions, decarburization, surface roughness, roll marks, and lamination. Scale, an oxide layer formed during manufacturing, appears as a flaky, rough coating and impacts steel quality. Surface cracks, caused by improper cooling, handling, or excessive stress, weaken the steel. Inclusions, non-metallic impurities like oxides or sulfides, create weak spots. Decarburization, carbon loss from the billet's surface due to high temperatures or inadequate protection, reduces hardness and strength. Surface roughness, irregularities from processing or handling, affects appearance. Roll marks result from issues with rolling mill equipment. Lamination refers to layering or separations within the billet, caused by poor solidification, temperature control, or impurities. Detecting and addressing these defects is crucial for producing high-quality steel. Inspection techniques like visual inspection, ultrasonic testing, magnetic particle testing, and eddy current testing help identify and classify defects.
- Q:Are there any alternative materials to steel billets in certain applications?
- Yes, there are several alternative materials to steel billets in certain applications. Some of these alternative materials include: 1. Aluminum: Aluminum is a lightweight and corrosion-resistant material that is commonly used as an alternative to steel in applications where weight reduction is important, such as in the aerospace industry. 2. Copper: Copper is a ductile and highly conductive material that is often used in electrical and plumbing applications. It is an alternative to steel billets in applications where high electrical conductivity is required. 3. Titanium: Titanium is a lightweight and high-strength material that is commonly used in applications that require both strength and corrosion resistance, such as in the automotive and aerospace industries. 4. Composite materials: Composite materials, such as carbon fiber reinforced polymers, are increasingly being used as alternatives to steel in applications where weight reduction and high strength are critical, such as in the construction of aircraft and high-performance sports equipment. 5. Plastic: Some applications that do not require high strength or durability can use plastic as an alternative material to steel billets. Plastic is lightweight, cost-effective, and can be easily molded into various shapes. It is important to consider the specific requirements of each application when choosing an alternative material to steel billets, as each material has its own unique properties and limitations.
- Q:How do steel billets contribute to the manufacturing of construction supplies?
