The plating coat of Aluminium-Zinc Alloy Armor plate is Zn-Al alloy, and its composition is 55% Al, 43.3% Zn and 1.6% Si. The plate is of smooth surface and excellent corrosion resistance of the atmosphere, which is 2 to 6 times higher than hot-dip galvanized sheet of the same thickness of plating coat. After through three processes, including payoff reel, crop shear and welding, enter into the continuous annealing furnace. During the annealing process, strips are heated closer to the recrystallizing temperature, and then heated to 20~50°C above the recrystallizing temperature in the reducing furnace. After keeping the same temperature for 170s, strips are naturally cooled to the normal temperature in the slow cooling process. Afterward, strips enter into the zinc pot through the elephant’s trunk and begin in the hot-dip coating process. The optimum temperature range of the plating coat is 630°C~660°C. Coated with aluminium-zinc alloy, strips enter into the cooling tower by the steady roll and air knife. After fast cooled with wind or water, they are directly produced into Al-Zn armor plates. The general rate of cooling is 30°C/s or so, and strips are cooled to about 60°C.

Q:How are steel coils used in the production of containers?: Steel coils are used in the production of containers as they are the primary material for manufacturing container bodies. These coils are shaped and welded into the desired container shape, providing strength and durability to the final product.

Q:i have been playing with hand me down graphite shaft irons and wedges. i was wondering if someone of my stature (5'3, 90 lbs., 12 years old) should be using steel shafted irons. i can definately swing them im just wondering if they are better for making contact: It depends on your swing speed. If you have a faster swing speed and notice you are consistently hitting high with your irons and having some trouble with accuracy, you will benefit from playing steel shafted irons. If your swing speed is on the slower end of the spectrum, stick with the graphite irons for a couple more years until you swing has developed and you are hitting farther.

Q:How do steel coils contribute to seismic resistance in structures?: Steel coils contribute to seismic resistance in structures by providing strength and flexibility. When placed strategically within the structure, steel coils can absorb and dissipate the energy generated during an earthquake, reducing the impact on the overall structure. This makes the structure more resistant to seismic forces, preventing or minimizing damage that could occur during an earthquake.

Q:Does aluminum or steel hold up better? We found a steel for 1/2 the price of aluminum, obviously its heavier but any other downsides? rust faster ect? also, does anybody know, in PA do you pay sales tax on trailers? and do dealers normally give you license plates to get the trailer home with? we live 3 hours away from the dealer so thats why i want all details :) would stink if i messed up!!: I bought a steel trailer. It was much heavier than the aluminum, as you said. But really, they are equivalents. As long as you have enough power to haul the trailer, you can use steel. We never had a rust problem with ours. In PA you do pay sales tax on horse trailers, stock trailers, etc. I forget about the plates, though. It's been a few years since we got our trailer. I would assume they would give you something to get the trailer home with though.

Q:How do steel coils contribute to fire resistance in buildings?: Steel coils contribute to fire resistance in buildings in several ways. Firstly, steel coils have high melting points, which means they can withstand extremely high temperatures without losing their structural integrity. This helps prevent the collapse of the building during a fire. Additionally, steel coils have low thermal conductivity, meaning they do not readily transfer heat. This property helps to contain the spread of fire, preventing it from spreading rapidly within the building. Moreover, steel coils can be used to reinforce concrete structures, enhancing their fire resistance. By providing strength and stability to the building, steel coils play a crucial role in ensuring the overall fire safety of the structure.

Q:What are the common methods of slitting or shearing steel coils?: The common methods of slitting or shearing steel coils include: 1. Rotary Shearing: This method involves using a rotary shear machine that uses a set of rotating blades to cut through the steel coil. The blades move in a circular motion, slicing through the coil to create individual strips of the desired width. 2. Scissor Shearing: Scissor shearing is another common method of cutting steel coils. It involves using a pair of scissor-like blades to make the cuts. The blades are typically operated by hydraulic or mechanical systems, and they cut through the coil by exerting pressure on the material. 3. Slitting: Slitting is a popular method used to cut steel coils into narrower strips. It involves passing the coil through a set of circular blades, known as slitters, which are set at specific distances apart. The slitters cut through the coil, creating multiple narrower strips of the desired width. 4. Guillotine Shearing: Guillotine shearing is a method that uses a large, powerful guillotine machine to cut through the steel coil. The machine features a long blade that moves vertically to shear the coil. This method is often used for thicker steel coils and can produce clean, straight cuts. 5. Laser Cutting: Laser cutting is a more advanced method that uses a high-powered laser beam to cut through steel coils. The laser beam is directed by computer-controlled systems, allowing for precise and accurate cutting. Laser cutting is often used for complex shapes or when high precision is required. Each of these methods has its advantages and is suitable for different applications. Factors such as the thickness of the steel coil, desired strip width, and the level of precision required will determine the most appropriate method to use.

Q:How are steel coils inspected for bendability?: Steel coils are inspected for bendability using a variety of methods to ensure their suitability for various applications. One common inspection method is the 3-point bend test, where the coil is subjected to a bending force at three specific points along its length. This test helps determine the coil's resistance to bending without fracturing or breaking. During the 3-point bend test, the coil is placed on a support system with two fixed points and one movable point. A force is then applied to the movable point, causing the coil to bend. The amount of force required to achieve a specific level of bending is measured and compared against acceptable standards. Another method used for inspecting steel coils is the mandrel bend test. In this test, a mandrel of a specific diameter is inserted into the coil and bent to a specified angle. The coil is then examined for any signs of cracking or deformation. This test helps determine the coil's flexibility and ability to withstand bending without damage. Visual inspection is also an important part of the inspection process. Trained inspectors visually examine the coil for any visible defects such as cracks, deformations, or irregularities. They also check for proper coil dimensions and uniformity throughout. In addition to these methods, non-destructive testing techniques like ultrasonic testing or magnetic particle inspection may be used to detect any internal defects or flaws that may affect the bendability of the coil. Overall, a combination of mechanical testing, visual inspection, and non-destructive testing methods are employed to ensure that steel coils meet the required bendability standards. These inspections help ensure the quality and reliability of the steel coils for various industries where bendability is a critical factor.

Q:How are steel coils used in the production of furniture?: Steel coils are used in the production of furniture to provide structural support and durability. They are commonly used in the construction of sofas, chairs, and other seating furniture to create a strong and sturdy foundation. The coils are typically incorporated into the furniture's frame or used in the construction of the seat cushions, providing comfort and resilience.

Q:What are the common coil storage conditions?: The common coil storage conditions include storing coils in a dry and clean area, away from direct sunlight and extreme temperature variations, and ensuring proper ventilation to prevent moisture buildup. It is also important to stack the coils properly, avoiding any damage or deformations, and to label and organize them for easy identification and retrieval.
