- Q: did bible stated that steel is coming from outer space. i mean meteor rocks that enter our earth sistem contains the minerals iron.
- First of all, use spell check and read back over what you wrote before submitting it. Second of all steel is a product made from iron through a very complicated scientific process which I will not bother to explain to you at this time. Iron is a naturally occuring substance on our planet which is mined from within the earth like other minerals. Furthermore, I don't recall the Bible saying anything about steel from outer space. What Bible are you reading?
- Q: What is the average tensile strength of a steel coil?
- The average tensile strength of a steel coil can vary depending on the specific grade and type of steel used. However, on average, steel coils typically have a tensile strength ranging from 300 to 2,500 megapascals (MPa).
- Q: I'm looking for a steel plate for an design project that requires neodymium magnets to be stuck on them. I am trying to figure out what kind of steel plate would have hold the magnets up the best.
- 1) Not to be mean or anything but Steel is an alloy. Anything metal or of metallic nature is an alloy. 2) Iron although not very strong attracts magnets the best.
- Q: How are steel coils processed at the steel service centers?
- Steel coils are processed at steel service centers through a series of steps. First, the coils are unrolled and flattened using a decoiler and a leveling machine. Then, the steel is cut into the desired length and width using shears or slitting machines. Next, the coils may undergo various treatments such as pickling, galvanizing, or coating to enhance their corrosion resistance or appearance. Finally, the processed coils are inspected, packaged, and prepared for shipment to various industries for further manufacturing or construction purposes.
- Q: They are showing on tv a special on how the new World Trade Center, building 1, is being built. Focusing on the steel and the guys fitting everything together.Where do builders go to buy all that steel framing? We do not build really tall buildings where I live so most of the steel is cut and welded on the job site. At World Trade Center 1, they seem to get the steel on trucks; already cut and welded.
- The steel is all custom fabricated in what are called structural steel fabrication shops. Each Building is designed by architects then the frame is designed by engineers to support whatever load is being applied to the building. After the engineering is done it goes out for a bid package where a fab shop estimates how much to charge for the fabrication of the steel and the erection of the steel. Once a company wins the bid, it then has to design how the steel will connect with one another and have it approved by an engineering firm to assure the connections are strong enough. Once all of that happens the fab shop orders raw steel beams and angle iron and steel plate at stock lengths. Beams are then cut into the right length and holes drilled in the proper places. The beam is then marked with a number that tells the erectors where it goes. The steel is then shipped out in batches to the construction site where it is unloaded and shook out into an organized place to grab them with a crane. They are then put together like a toy model, there are instructions that say what beam goes where and what size bolt to use. The welding you see being done is on really critical moments that need extra strength. That is about how it goes in a nutshell. It is a bit more complicated than that but it gives you an idea.
- Q: What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
- Hot rolled coil is used for continuous casting slab or as raw material, after reheating furnace heating, descaling into the roughing mill of high pressure water, roughing material by cutting head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling, after finishing through the laminar cooling (computer controlled cooling rate and coiling) reel, a straight hair volume. Hair straightenerrollhead, tail tongue shapeand thefishtail shape, thickness, width of poor accuracy, edgehaswavy, folding, tower and other defects. The volume is heavy. (general management industry likes to use. )
- Q: What is the process of galvanizing steel coils?
- Enhancing the durability and protecting steel coils from corrosion involves a series of steps in the galvanization process. To begin, the steel coils undergo a thorough cleaning to eliminate any dirt, oil, or impurities on the surface. This is achieved through an acid pickling process, where the coils are immersed in a diluted acid solution or treated with a chemical cleaner. The aim is to ensure the surface of the coils is free from contaminants, allowing for better adhesion of the zinc coating. Following the cleaning process, the coils are rinsed to remove any remaining acid or cleaner, preventing adverse reactions in the next stage. The subsequent step involves the actual galvanization, where the cleaned coils are submerged in a bath of molten zinc. To guarantee an even coating, the coils are carefully passed through the zinc bath using rollers or other mechanisms. The zinc bath is maintained at a specific temperature, typically around 450°C (842°F), enabling the molten zinc to bond with the steel surface. Upon withdrawal from the zinc bath, excess zinc is eliminated by passing the coils through air knives or by centrifugal spinning. This ensures control over the thickness of the zinc coating, resulting in a uniform appearance. Once the galvanization process is complete, the steel coils are gradually cooled to room temperature. This facilitates the solidification and firm bonding of the zinc coating with the steel surface, creating a protective barrier against corrosion. The final step involves inspection and quality control. The galvanized steel coils are carefully examined for any defects, such as uneven coating or areas with insufficient zinc coverage. This inspection is typically conducted visually or using specialized equipment capable of detecting anomalies. Additionally, the coating thickness is measured to ensure it meets the required specifications. In conclusion, the galvanization process for steel coils is designed to enhance their longevity and shield them from rust and corrosion. By applying a layer of zinc coating to the steel surface, the coils become more resistant to environmental factors, making them suitable for a wide range of applications across various industries.
- Q: How are steel coils cleaned?
- Steel coils are typically cleaned using a combination of chemical and mechanical processes. The coils are first treated with a degreasing agent to remove any oil or grease present on the surface. Then, high-pressure water jets or brushes are used to scrub away any remaining dirt or contaminants. The coils may also undergo a rinsing process to ensure all cleaning agents are removed. Additionally, some manufacturers may use acid cleaning or pickling techniques to remove scale or rust from the surface of the coils.
- Q: not iron, steel
- steel was first used in the 1800s in buildings.
- Q: What are the different methods of coating steel coils?
- There are several different methods of coating steel coils, each offering unique benefits and applications. Some of the most common methods include: 1. Hot-dip galvanizing: This process involves immersing the steel coils in a bath of molten zinc. The zinc forms a protective layer on the surface of the steel, providing excellent corrosion resistance and durability. 2. Electro-galvanizing: In this method, a layer of zinc is applied to the steel coils using an electroplating process. It provides similar corrosion resistance to hot-dip galvanizing but with a thinner coating. 3. Electro-coating (E-coating): Also known as electrodeposition, this method involves immersing the steel coils in a bath of paint or resin containing electrically charged particles. An electrical current is applied, causing the particles to adhere to the surface of the steel. E-coating provides excellent corrosion protection and is often used as a primer before applying additional coatings. 4. Powder coating: Steel coils can be coated with a dry powder paint that is electrostatically charged and then baked onto the surface. This method offers a wide range of colors, finishes, and textures, providing both aesthetic appeal and corrosion resistance. 5. Organic coatings: These coatings, such as paints or lacquers, are applied to the steel coils using various techniques like spray, roller, or dip coating. Organic coatings provide protection against corrosion, as well as offering customizable colors and finishes. Each method of coating steel coils has its advantages and is selected based on the desired level of corrosion resistance, appearance, and specific end-use requirements.
