- Q: What are the different types of cleaning equipment used for steel billets?
- Steel billets commonly undergo cleaning using various types of equipment. These include: 1. Shot blasting machines: These machines propel small metal or mineral particles at high speed onto the surface of the billets, effectively eliminating rust, scale, and other contaminants, resulting in a clean and smooth surface. 2. Ultrasonic cleaners: Through the use of high-frequency sound waves, ultrasonic cleaning agitates a cleaning solution, effectively removing dirt, oil, and other contaminants from the billets' surface. This method is particularly useful for stubborn or hard-to-reach contaminants. 3. Acid pickling tanks: By immersing the billets in an acidic solution, acid pickling dissolves rust, scale, and other contaminants. After pickling, rinsing and drying are usually carried out. 4. Power washers: Power washers, also known as pressure washers, employ a high-pressure water spray to eliminate dirt, oil, and other contaminants from the billets' surface. This method is particularly effective for larger or heavier billets. 5. Mechanical cleaning brushes: Mechanical cleaning brushes, including wire brushes or abrasive pads, are commonly employed to manually scrub the billets' surface, removing loose dirt, rust, or scale. Typically used in conjunction with other cleaning methods. In determining the appropriate cleaning equipment for steel billets, factors such as the extent and type of contaminants, desired level of cleanliness, and the size and shape of the billets need to be considered. Different combinations of these cleaning methods may be utilized to achieve the desired outcome.
- Q: What is the typical composition of steel billets?
- The typical composition of steel billets can vary depending on the specific requirements and intended use. However, in general, steel billets are primarily composed of iron and carbon, with other elements added to enhance certain properties. The carbon content in steel billets is typically around 0.1-0.3%. In addition to iron and carbon, steel billets often contain small amounts of other elements such as manganese, silicon, sulfur, and phosphorus. Manganese helps improve the strength and hardness of the steel while also promoting better heat treatment response. Silicon is commonly added to enhance the steel's fluidity during casting. Sulfur and phosphorus are impurities that need to be minimized as they can negatively affect the steel's machinability and mechanical properties. Furthermore, alloying elements such as chromium, nickel, molybdenum, and vanadium may also be present in steel billets to impart specific properties. For instance, chromium improves corrosion resistance, nickel enhances toughness and ductility, molybdenum increases high-temperature strength, and vanadium improves wear resistance. Overall, the composition of steel billets is carefully controlled to achieve the desired mechanical, physical, and chemical properties required for the subsequent processing and final applications of the steel.
- Q: What are the main factors affecting the hardenability of alloy steel billets?
- The main factors affecting the hardenability of alloy steel billets include the chemical composition of the alloy, the grain size and distribution, the cooling rate during heat treatment, and the presence of alloying elements such as carbon, manganese, chromium, and molybdenum. These factors determine the ability of the steel to form and retain a hardened structure, thus affecting its overall hardness and strength properties.
- Q: How are steel billets reheated before rolling or forging?
- Steel billets are reheated before rolling or forging by passing them through a furnace or a reheating furnace, which raises their temperature to a specific range. This process, known as billet reheating, is crucial as it improves the billets' malleability, making them easier to shape and work with during the subsequent rolling or forging operations.
- Q: What is the shelf life of a steel billet?

- the only way to avoid pinhole of slag situation.1, after foaming, a large amount of gas and residue are produced, which is the main source of porosity and slag inclusion in the cast steel.2, steel casting pouring system or ingate structure is not reasonable, easy to make the gas and residue involved in the liquid metal, the formation of porosity and slag.3, pouring temperature is too low, can not make the cast steel parts of the gas and residue fully excluded, floating up to the top of the casting, but also easy to produce porosity and slag inclusion.4, in some parts of the cast steel parts, when the permeability of the paint is very low, due to the role of gas back pressure, it is easy to make the gasification gas wrapped in the epidermis, forming a package of gas".
- Q: How to calculate the cost price of billet?
- The ratio of slag to billet (63% fine powder) is about 3:1, which accounts for about 60%. of billet cost
- Q: What are the main factors affecting the weldability of steel billets?
- There are several main factors that affect the weldability of steel billets. Firstly, the composition of the steel billet plays a significant role. The presence of certain elements, such as carbon, sulfur, phosphorus, and nitrogen, can have a detrimental effect on weldability. Higher carbon content, for example, can lead to the formation of brittle regions in the weld zone. Similarly, elements like sulfur and phosphorus can cause porosity and other defects in the weld. Secondly, the heat treatment history of the steel billet is another important factor. Processes like annealing, quenching, and tempering can alter the microstructure of the steel, affecting its mechanical properties and weldability. For instance, a steel billet that has been excessively hardened may experience cracking during the welding process. Thirdly, the presence of impurities and contaminants in the steel billet can adversely affect weldability. These impurities can lead to the formation of inclusions or other defects in the weld, reducing its strength and integrity. It is crucial to ensure that the steel billet is clean and free from contaminants before welding. The size and shape of the steel billet also impact weldability. Thicker billets, for example, require higher heat input during welding, which can lead to increased residual stresses and distortion. Similarly, complex geometries or irregular shapes may make it challenging to achieve proper joint penetration and fusion during welding. Lastly, the welding process itself can influence the weldability of steel billets. Factors such as welding technique, heat input, welding speed, and the use of filler materials can all affect the quality of the weld. It is essential to select the appropriate welding process and parameters to ensure a sound and defect-free weld. Overall, the main factors affecting the weldability of steel billets include composition, heat treatment history, impurities, size and shape, and the welding process. Considering and managing these factors is crucial to achieve high-quality welds and ensure the integrity and performance of steel structures.
- Q: What is the average production cost of steel billets?
- The average cost of producing steel billets can differ depending on various factors such as location, production scale, raw material expenses, energy expenditures, labor charges, and other operational outlays.
