Q: Help me compare the speed of sound in air, water, and steel please?Thanks.: Speed Of Sound In Steel

Q: 911 conspiacy theorists. Can fire melt steel?: Don't know the differences in steel strength between the WTC towers and the bridge, but I'll tell you they don't always use the strongest steel in buildings. It is a question of value engineering. Engineers do as code requires, and make the determination based on economics of building. If a steel member requires say 48 KSI, with certain span, but if the price is less expensive to use 35 KSI and reduce the span by adding vertical elements then that is an option that the architects, engineers and developers consider. Like I said, don't much about bridge engineering, but in buildings, it isn't always the strongest steel, based on engineering and economics. And BTW, said time and time again, but ok one more time. STEEL DOESN'T NOT HAVE TO MELT FOR FAILURE. IT LOSES STRENGTH WITH HEAT. THAT IS WHY IT MUST BE PROTECTED BY FIRE RETARDANT. BUT IF THE FIRE RETARDANT IS REMOVED BY EXPLOSION, THEN FIRE CAN CAUSE FAILURE. Sorry for the shouting, but I'm not the only one who says that, but people keep saying steel can't melt, but it doesn't have to for failure. If the steel joist had been in concrete, the WTC towers may have stood, at least longer. But hindsight is 20/20.

Q: When steel is cast, does it become weaker/more brittle or anything of this nature? what are the side effects of steel casting on the steel itself?How can you correct these?: It contains too many air bubble spacing and too many impurity that make it easily to be broken apart. Melt it down again with high heat to remove most impurity, after this process,it becomes iron.

Q: How are steel coils processed and treated?: To ensure the quality and suitability of steel coils for different applications, they undergo a series of steps and treatments. Initially, the coil is uncoiled by removing its protective wrapping and unwinding it. Any defects like cracks or uneven surfaces are then inspected. Next, the coil is cleaned to eliminate dirt, oil, and rust using chemical agents and mechanical scrubbing. After cleaning, it is rinsed and dried to prevent corrosion caused by residual moisture. Once cleaned, the steel coil may be treated based on its intended use. One common treatment is pickling, where the coil is immersed in an acidic solution to remove impurities and scale. This improves the surface finish and prepares the steel for further processing. After pickling, the coil can undergo cold rolling, which reduces its thickness and improves dimensional accuracy. This is done by passing the steel through a series of rollers at room temperature, gradually decreasing thickness and increasing strength. It also improves the surface finish. In some cases, the coil may undergo additional heat treatments like annealing or tempering. Annealing involves heating the coil to a specific temperature and slowly cooling it to relieve internal stresses and improve mechanical properties. Tempering, on the other hand, involves reheating the coil to a lower temperature and rapidly cooling it to enhance strength and toughness. Once the desired processing and treatments are completed, the steel coil may be coated or painted for added protection against corrosion or to enhance its appearance. Coating processes can include hot-dip galvanizing, electroplating, or applying organic coatings like paint or powder coatings. Finally, the processed and treated steel coils are cut into specific sizes or shapes according to customer requirements. This can be done using cutting methods such as shearing, slitting, or sawing. Overall, the processing and treatment of steel coils involve cleaning, pickling, rolling, heat treatment, coating, and cutting processes. These steps are carefully carried out to ensure the quality, strength, and suitability of the steel for its intended applications.

Q: What are the different methods of cutting edge trimming for steel coils?: There exist multiple techniques for trimming steel coils, each with unique benefits and applications. Some of the frequently employed methods are as follows: 1. Shearing: This method entails cutting the steel coil's edge using sharp blades. It is a quick and efficient technique suitable for high-volume production. However, shearing may lead to slight distortion or burrs along the cut edge. 2. Slitting: Slitting involves passing the steel coil through rotating circular blades, resulting in narrower strips. This method is commonly adopted when precise width control is necessary, such as for the production of narrow strips or coils with multiple widths. 3. Laser cutting: Laser cutting is a highly precise technique that employs a laser beam to cut through the steel coil. It offers the advantage of producing clean and precise cuts without any distortion or burrs. Laser cutting is frequently used for intricate or complex shapes that require high accuracy. 4. Plasma cutting: Plasma cutting utilizes an ionized gas jet to cut through the steel coil. It is particularly suitable for thicker materials or applications where high cutting speeds are required. Plasma cutting can generate clean and smooth cuts, although a slight bevel may be present on the edge. 5. Waterjet cutting: Waterjet cutting employs a high-pressure jet of water mixed with an abrasive substance to cut through the steel coil. This technique is highly versatile and can be used for various materials and thicknesses. Waterjet cutting is renowned for producing precise cuts without any heat-affected zone. 6. Sawing: Sawing is a traditional method that involves using a rotating saw blade to cut through the steel coil. It is commonly used for thicker materials or when a rougher cut is acceptable. Sawing can be performed manually or with the assistance of automated sawing machines. Each method possesses its own advantages and considerations, and the selection depends on factors such as required accuracy, production volume, material thickness, and desired edge quality.

Q: What are the common coil lengths available for steel coils?: The steel coil lengths offered in the industry and specific requirements are subject to variation. Nonetheless, several standard coil lengths are extensively employed in different applications. These encompass coil lengths of 100 feet (30.48 meters), 200 feet (60.96 meters), 300 feet (91.44 meters), and 500 feet (152.4 meters). These lengths find extensive use in construction, manufacturing, and automotive sectors, where steel coils serve diverse purposes. It is worth mentioning that coil lengths can also be tailored to meet specific project requirements or customer preferences.

Q: How are steel coils unloaded from a truck or ship?: Various equipment and techniques are typically employed to unload steel coils from trucks or ships. The unloading procedure depends on the coils' type and size, as well as the available resources and infrastructure at the unloading site. When unloading from a truck, coil hooks are often used in conjunction with a forklift or crane. Careful lifting and positioning of the coils onto the ground or a designated storage area are carried out. Alternatively, specialized roll-off trailers may be fitted to certain trucks, enabling the coils to be rolled off the truck bed. Larger cranes are commonly utilized when unloading from a ship, given the coils' considerable size and weight. These cranes can be situated on either the ship or the dock itself. Specialized lifting hooks or spreader bars are employed to lift the coils from the ship's cargo hold, ensuring they are lowered with care onto the dock or a waiting truck. In certain instances, coil transfer cars or coil trailers are used to transport the coils from the ship's cargo hold to the unloading area. These devices are designed to safely and efficiently move and position the coils. It is important to emphasize that safety measures play a critical role during the unloading process. Properly securing the coils, ensuring equipment stability, and adhering to weight limits are essential to prevent accidents or damage to the coils, truck, or ship. In summary, unloading steel coils from trucks or ships necessitates the use of specialized equipment such as cranes, forklifts, and coil hooks. These tools, combined with meticulous planning and safety precautions, guarantee the efficient and secure transfer of the coils to their designated storage or transportation areas.

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.

Q: How is the demand for steel coils influenced by the construction sector?: The demand for steel coils is heavily influenced by the construction sector. As construction activities increase, so does the demand for steel coils as they are essential for various construction applications such as structural components, roofing, and reinforcing materials. Conversely, when construction activities decline, the demand for steel coils also decreases. Therefore, the construction sector plays a crucial role in driving the demand for steel coils.

Q: How are steel coils inspected for quality control purposes?: Steel coils are inspected for quality control purposes through various methods such as visual inspection, dimensional checks, and non-destructive testing techniques. Visual inspection involves examining the surface of the coil for any defects or irregularities. Dimensional checks are conducted to ensure that the coil meets the specified thickness, width, and length requirements. Non-destructive testing techniques like ultrasonic testing or magnetic particle inspection are used to detect internal flaws or defects in the steel coil. These inspection methods help ensure that the steel coils meet the desired quality standards before they are used in various applications.
