STEEL BILLET
1.Brief description
Steel billet(ingot) by cogging or breakdown of semi-finished products, is the raw material of all kinds of steel mill. Billet section of square, round, flat, rectangular and abnormity of several kinds of, mainly related to the shape of rolled products.
2.Features
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.
3.Processing
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.

5.Usage
Billets, or ingots (as they sometimes referred to), are not of practical use until they have been formed into more functional shapes and sizes. While they have already been put in the furnace, they still require a series of shaping and molding procedures such as hot and cold working, milling and cutting before they are sold in hardware stores, or used for different applications. The unformed billets, however, can be used in striking currency such as coins and as reserves, similar to gold bars.

- Q:What are the different methods of surface cleaning for steel billets?
- Some of the different methods of surface cleaning for steel billets include abrasive blasting, acid pickling, mechanical cleaning, and electrochemical cleaning.
- Q:The form of carbon in carbon steels
- There are three solid solutions of carbon in iron: alpha solid solution (Tie Suti), gamma solid solution (austenite) and delta solid solution (8 ferrite). The spatial distribution of iron atoms in these solid solutions is consistent with that of alpha -Fe, gamma -Fe and delta -Fe. The size of carbon atoms is much smaller than that of iron atoms.
- Q:What are the different surface defects found in stainless steel billets?
- Stainless steel billets may exhibit several surface defects. Some commonly encountered defects include: 1. Scale: During the heating process, a thin layer of oxide known as scale forms on the billet's surface. It manifests as a rough, dark layer and can be easily eliminated through pickling or passivation methods. 2. Pitting: Localized corrosion, resulting in small, shallow pits on the billet's surface, is referred to as pitting. It occurs due to chloride ions or other aggressive chemicals and may compromise corrosion resistance. 3. Scratches: Linear marks visible on the billet's surface are indicative of scratches. These scratches can occur during handling, transportation, or processing, potentially impacting the material's appearance and integrity. 4. Lamination: Improper rolling or inadequate bonding during manufacturing can lead to lamination defects, which manifest as thin layers or flakes parallel to the billet's surface. 5. Inclusions: Non-metallic particles or impurities embedded in the stainless steel billet are referred to as inclusions. They have the potential to affect the material's mechanical properties and corrosion resistance. 6. Decarburization: Heating may cause carbon loss from the billet's surface, resulting in decarburization. This manifests as a light-colored layer and can adversely affect the material's strength and hardness. 7. Cracks: Thermal stresses, improper cooling, or mechanical damage can cause cracks in the billet. These cracks can be either surface cracks or internal cracks, significantly weakening the billet. Detecting and addressing these surface defects is crucial to ensure the quality and performance of stainless steel billets across various applications.

- Q:How are steel billets used in the production of seamless pipes?
- Seamless pipes, which are manufactured without welding or seams, require steel billets as a fundamental component in their production process. Steel billets are rectangular-shaped solid pieces of steel that serve as the raw material for seamless pipe manufacturing. To produce seamless pipes, the initial step is melting steel in a furnace to obtain molten metal. This molten steel is then poured into molds to shape steel billets. These billets are then heated to a specific temperature and pierced using a piercing mill. This mill exerts both axial and radial forces, pushing a pointed mandrel through the center of the billet, resulting in a hollow tube or shell. Following the piercing process, the hollow tube is further elongated and reduced in diameter by a series of rolling mills. These mills apply a combination of rotational and compressive forces to shape the billet into the desired seamless pipe size. The seamless pipe undergoes continuous stretching and rolling until it reaches the desired length and diameter. The utilization of steel billets in the production of seamless pipes holds significant importance for several reasons. Firstly, the billets are crafted from high-quality steel, guaranteeing the strength and durability of the final product. Secondly, the uniformity and consistency of the billets allow for precise shaping and seamless pipe dimensions. Lastly, the solid structure of the billets enables them to withstand the intense forces and temperatures involved in the pipe manufacturing process. In conclusion, steel billets assume a crucial role in the production of seamless pipes. From being melted and molded into billets to being pierced, elongated, and rolled, these billets undergo a series of processes that transform them into high-quality seamless pipes. The use of steel billets ensures the integrity and reliability of seamless pipes, making them suitable for various industrial applications.
