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: no it is not, he made that up steel is a conductor and can't build static electricity. Compass needle is a magnet and as such was attracted to steel .

Q: How are steel coils made?: Steel coils are made through a process called hot rolling, where steel slabs are heated and passed through a series of rollers to reduce their thickness and shape them into long, coiled strips. This process helps enhance the steel's strength and flexibility, making it suitable for various industrial applications.

Q: Can steel coils be coated with anti-graffiti materials?: Yes, steel coils can be coated with anti-graffiti materials. These materials are designed to prevent graffiti from adhering to the surface of the steel coil, making it easier to remove any graffiti that may be applied.

Q: What are the different types of steel coil slitting processes?: There exist various steel coil slitting processes, each with its own advantages and considerations. Listed below are some of the most common methods: 1. Rotary slitting: This traditional and widely-used process involves a circular blade that rotates to cut through the coil. Rotary slitting is known for its precision and ability to produce narrow strips, making it suitable for a wide range of applications. 2. Loop slitting: This method requires the coil to pass through a loop before being cut. It enables high-speed processing and can handle thicker materials. Loop slitting is commonly applied in heavy-duty applications and with large coils. 3. Drag slitting: Also referred to as shear slitting, this process utilizes a stationary blade to pull the material and make the cut. Drag slitting is ideal for thinner materials and provides a high-quality edge finish. 4. Crush slitting: By pressing the material between two rollers, crush slitting achieves the desired cut. It is commonly used for delicate materials that require a gentle cutting action. This method ensures clean cuts and minimizes burrs. 5. Laser slitting: As implied by its name, this process employs a laser beam to cut through the coil. Laser slitting provides high precision and can handle various materials. It is especially advantageous for specialty steels and thin strips. When selecting the appropriate method, it is crucial to consider factors such as material thickness, coil size, and required strip width for each type of steel coil slitting process. Additionally, factors like cost, speed, and edge finish should also be taken into account to determine the most suitable process for a specific application.

Q: How are steel coils used in the manufacturing of automotive accessories?: Steel coils are used in the manufacturing of automotive accessories as they are processed and shaped into various components such as brackets, frames, and supports. These coils are typically cut, molded, and stamped into specific shapes before being assembled into the final product, adding strength and durability to the accessories.

Q: I have a white gold engagement ring, and to be special I thought I'd get a plain band from Tiffany's--in stainless steel. Can stainless steel be worn with white gold or will there be a difference in the color or texture? I'm not planning on getting them soldered together, but I don't want it to be noticeable that they are different metals. Does anyone have experience in this subject?: I am a manufacturing Jeweller. Yes there is a difference in the colour between Stainless Steel and White Gold. The wear characteristics are also different so you will notice a difference in the wearing of the rings. I would doubt that tiffany's would make stainless steel rings. Most likely they are stocking Titanium rings, which look like stainless steel. But the same problems of colour and wear exist for that metal as well. Your best bet is to get a white gold ring , and check out other manufacturing jewellers first because you will not be getting an investment from Tiffany's. Their profit margin is that high you would get a nosebleed. the scrap value of a 5 gram 18ct white gold wedder is $120. anything over that is the profit margin of the jeweller. for a plain wedder I charge $20 per gram to make plus the gold so that would be a total cost of $220 for a 5 gram ring and $440 for a 10 gram ring. I hope this is good information to you Also you must ask what type of 18ct white gold are you getting? there is; Platinum alloy Palladium alloy Irridium alloy Nickel Zinc alloy or a combination of any or all of the above with prices accordingly

Q: How are steel coils used in the manufacturing of safety systems?: Steel coils are commonly used in the manufacturing of safety systems as they provide strength, durability, and stability to various components. These coils are often transformed into springs, which are crucial for absorbing and distributing impact forces during accidents or sudden movements. Springs made from steel coils are utilized in seatbelt retractors, airbag systems, suspension systems, and other safety mechanisms to enhance overall safety and protect occupants in vehicles and various industrial applications.

Q: How are steel coils inspected for straightness?: Steel coils are inspected for straightness through a variety of methods to ensure they meet the required quality standards. One common method is visual inspection, where trained inspectors visually examine the coil for any visible defects or deformations that may indicate a lack of straightness. They carefully observe the coil's edges, surface, and overall shape to identify any irregularities. Another method used is measuring the coil's straightness using precision instruments. This involves taking measurements at various points along the coil's length and comparing them against specified tolerances. Techniques such as laser measurements or straightness gauges are employed to accurately assess the deviation from the desired straightness. Furthermore, some coils undergo non-destructive testing, such as magnetic particle inspection or ultrasonic testing, to identify any internal defects or stresses that could affect the straightness. These tests can reveal hidden flaws that may not be evident through visual inspection alone. In addition, some manufacturers may employ automated inspection systems that utilize advanced technologies like computer vision or artificial intelligence. These systems can quickly scan the coil's surface and analyze it for any deviations from straightness, providing precise measurements and ensuring consistent quality. Overall, the inspection of steel coils for straightness involves a combination of visual inspection, precise measurements, non-destructive testing, and advanced technologies. These methods aim to identify any deviations from the required straightness, ensuring that only coils meeting the specified standards are used in various applications.

Q: for my engineering project I have been asked to design a method of suspending a TV of weight 14Kg from a gantry, the TV must be 5m below the gantry. My team have decided to use as a suspension method a steel cylinder of outer diameter of 10cm and an inner diameter of 8, however we now need to work out both the max stress and strain and the actual stress and strain. and help would be useful: In most engineering calculations we have to make some assumptions about ideal behavior of a material otherwise we would not be able to simplify our equations to manageable sizes. Your steel cylinder (which I'll call a pipe) is made of a certain type of steel. That steel type has property tolerances listed in a steel manual to help you know about your steel before you begin. You'll need to know the cross-sectional area of the pipe and the weight of the TV to determine an average stress on the pipe. Obviously the weight of the TV is the force it generates. The force is its mass x gravitational acceleration. Since we typically think of steel as an elastic material, we think of it stretching like a rubber band or a spring. You pull it down with a TV and it deflects a certain amount, and will return to its original length when the TV is removed. It is typical to assume that all steel, regardless of its strength, has the same value for this elastic property. It is commonly referred to as the elastic modulus. This value will help you determine what type of strain occurs under what type of stress. So, once you have the stress, you can get the strain by using the elastic modulus. Once you have the strain you can determine the deflection based on the pipe length. Having the steel properties will help you determine how close your TV comes to stressing the pipe to its yield stress. If you reach a yield stress, your steel will deflect, but when you take the TV off it will not return to its original shape. I hope I've helped outline some of the things you'll need to do for the project, I tried not to give away specifics so that you can actually engage your brain around the project. Enjoy, learn a lot, and realize that this skill could easily turn into a career where you are designing projects that when done correctly save people's lives every day of the year.
