Q: Well the other day i told my friend that when you put a compass near steel it will screw up and he said only magnets do that then i showed him and it worked then he said: that'ss because steel has its own magnet in it coz it builds up static electricity is that correct what he said? thanks: If you sprinkle iron filings near a bar magnet (on paper, etc.) the filings will try to line up with the magnetic field (because iron atoms behave like tiny magnets). Bringing the compass near steel (mainly iron with a little carbon) will cause the iron to try to align with the magnet of the compass needle, however, because the needle is free to swing it also aligns with the magnetic field set up between the needle and steel. Any static electricity would have nil effect on the magnetic field.

Q: How are steel coils used in the manufacturing of automotive wheels?: Steel coils are used in the manufacturing of automotive wheels by being processed and shaped into the necessary components such as rims and spokes. These coils are cut, formed, and welded to create the desired wheel design, ensuring durability and strength for safe and reliable use on vehicles.

Q: What is the process of pickling and oiling steel coils?: The process of pickling and oiling steel coils involves several steps. First, the steel coils are immersed in a pickling bath containing a mixture of acids to remove any impurities, scale, and rust from the surface of the steel. This helps to improve the quality and appearance of the steel. After pickling, the coils are rinsed with water to remove any residual acid. Next, the coils are coated with a thin layer of oil. This oil acts as a protective barrier, preventing the steel from rusting or corroding during storage, transportation, and further processing. The oil also helps to enhance the surface finish of the steel. The pickled and oiled steel coils are then typically rolled or processed further according to specific requirements. This could involve additional annealing, cold rolling, or other treatments to achieve the desired properties or dimensions. Overall, the pickling and oiling process is crucial in preparing steel coils for various applications, ensuring they are clean, corrosion-resistant, and ready for further processing or use.

Q: How are steel coils used in the marine industry?: Steel coils are commonly used in the marine industry for various purposes such as shipbuilding, offshore structures, and maritime equipment. These coils are utilized in the construction of ship hulls, decks, and bulkheads due to their high strength and durability. Additionally, they are often used in the fabrication of marine equipment such as cranes, winches, and anchor systems. Steel coils are crucial in ensuring the structural integrity and longevity of marine vessels and components, making them an essential material in the marine industry.

Q: What are the common methods of painting or coating steel coils?: Coil coating is a commonly used technique for painting or coating steel coils. It involves cleaning and pre-treating the coils to remove contaminants and enhance adhesion. Next, a primer or base coat is applied to establish a solid foundation. This primer safeguards the steel against corrosion and enhances the overall durability of the coating. Once the primer is applied, the steel coils undergo a series of rollers to apply the topcoat. The topcoat can consist of various materials such as polyester, polyurethane, or fluoropolymer, depending on the desired properties of the final coating. These topcoats provide the desired color, gloss, and protection against weathering, chemical exposure, and UV radiation. Electrostatic spraying is another popular method for painting or coating steel coils. It involves atomizing the paint or coating material into fine droplets and charging them with electricity. The grounded steel coils attract these charged droplets, resulting in a controlled and even application of the paint or coating material. Powder coating is yet another technique utilized for painting or coating steel coils. It involves electrostatically charging a dry powder and spraying it onto the steel coils. The charged powder adheres to the steel surface due to electrostatic attraction. The coated steel coils are then heated, causing the powder to melt and form a continuous film, resulting in a durable and resistant coating. In conclusion, these methods provide a wide range of options in terms of color, finish, and performance characteristics for painting or coating steel coils. The choice of method depends on factors such as desired appearance, level of protection required, and specific application requirements.

Q: should I shoot Herters .308 steel cased ammo in my Remington 7400.and why shouldn't I?: I shouldn't have an R-25, however probabilities are that when you use metal cased ammo in it you are going to sometimes handle stuck instances. That's the rate you pay for the cheap ammo. As a rule when a case sticks without problems tapping the butt firmly on the ground then pulling the charging handle will dislodge and eject the case. It can pay to invariably have a cleaning rod with you, if the above repair does not work, you push the case out with the rod.

Q: Having a new kitchen and would like to know the pros and cons of stainless steel as opposed to white appliances. I can only think of finger marks on the SS, which I believe are difficult to remove. Anyone had both that they could advise please?: A relative had a stainless steel range. It always looked a fingerprinted mess. I have never liked it. To me, it is grey with a sheen. I hate grey. I am a white appliance person all the way. White makes the room look cleaner, brighter and larger and it is easy to keep clean. Stainless is a nightmare to keep clean. Almost forgot to mention, when we bought our house a few years ago, it had a stainless steel range, horribly marked and scratched. I got rid of it, in keeping with white.

Q: How are steel coils processed for slitting or edge conditioning?: Steel coils are processed for slitting or edge conditioning through a series of steps. First, the coils are uncoiled and fed into a slitting machine, where circular blades cut the coil into narrower strips. These strips are then rewound into smaller coils, ready for further processing. For edge conditioning, the strips are passed through a machine that trims and smoothens the edges, ensuring they are free from any sharp or rough edges. This process enhances the safety and usability of the steel strips for various applications.

Q: Explain your answers please. I was watching mythbusters and they bought a steel coffin over a wooden one because they thought it would hold more dirt. Now how come bridges that have been made of wood lasted way longer than steel bridges? Or rollercoasts for example.: steel bridges that have been made of wood lasted way longer than steel bridges NOT true. Why do you think bridges are made from steel or concrete, and not wood? wood rots and splinters and doesn't last more than 10 years when exposed to the weather. .

Q: How are steel coils used in the manufacturing of pressure vessels?: Steel coils are used in the manufacturing of pressure vessels as they are processed into flat sheets and then formed into the desired shape. These coils provide strength and durability to the pressure vessel, ensuring it can withstand high pressures and temperatures.
