Description of Prepainted Z80 Rolled Steel Coil for Sandwich Panel
Prepainted Rolled steel Coil is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
Main Feature of Prepainted Z80 Rolled Steel Coil for Sandwich Panel
1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.

- Q: How do steel coils compare to other materials, such as aluminum or copper?
- Steel coils have several advantages over other materials like aluminum or copper. Firstly, steel is generally stronger and more durable, making it suitable for heavy-duty applications. Steel coils also have a higher melting point, which means they can withstand higher temperatures without losing their structural integrity. Additionally, steel is typically more cost-effective and widely available compared to aluminum or copper. However, it's important to note that the choice between these materials depends on the specific requirements of the application, as aluminum and copper may offer advantages in certain scenarios such as electrical conductivity or weight reduction.
- Q: I heard on some shows that you can carbonise steel by heating it red hot then dropping it in black oil. i cant find this no where online, and the process for commercial carbon steel is totally different. can you really carbonise regular steel by heating it to red hot then dropping it in regular black oil. i saw it on mythbusters once. when the made carbon steel hammers to test if 2 hammers smashed together will shatter
- Carburized steel is not the same thing as carbon steel. All steel has carbon in it, but carbon steel is defined as Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 1.04 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. Carburizing is a surface treatment. Dropping hot steel in oil is oil quenching. It might get a little carbon in the surface, but oil quenching is mainly used as a slightly slower quenching process than water quenching, not for carburizing. Once it starts cooling down the carbon won't diffuse in. Quenching is used to change the hardness. The simplest way to carburize steel is to pack charcoal around it and heat it to 900 C or so. Industrial processes use a gas like carbon monoxide, but that's mostly just for easier process control.
- Q: I need the measurements of the height and hypotenuse of the first drop in the Steel Dragon 2000. I couldn't find it anywhere. It would be great if you could also show me the website where you got your answer. Thanks! =]*The hypotenuse is the length of the drop.*
- Steel Dragon 2000 is a roller coaster at Nagashima Spa Land Amusement Park in Mie Prefecture, Japan. Built by Morgan Manufacturing, this gigacoaster opened, appropriately, in 2000 - The Year of the Dragon in the Far East. It debuted only months after Millennium Force and surpassed the Cedar Point coaster as the world's tallest complete-circuit coaster. It also set a record for longest track length - 8133 feet, 2 inches (2479 m), which it currently holds. Coaster Facts * Steel Dragon 2000 is the tallest coaster to utilize a traditional chain lift. Because of the length of the lift hill, two chains are used - one for the bottom half and one for the top half. A single chain would have been excessively long and heavy, at least twice the weight of one of the trains. As a result, two trains can safely occupy the lift simultaneously. * The building of Steel Dragon 2000 required far more steel than other coasters for earthquake protection. This put the cost of the coaster at over $50,000,000. * On August 23, 2003, Steel Dragon 2000 was involved in an accident during a run in which one of its trains lost a wheel. The coaster did not operate during the 2004 and 2005 park seasons. It reopened September 3, 2006.
- Q: How are steel coils inspected for hardness?
- Various methods are used to inspect the hardness of steel coils, ensuring their quality and suitability for specific applications. The Rockwell hardness test is a common method, involving the use of a diamond or ball indenter pressed into the coil's surface to measure indentation depth. The hardness value is then determined based on this measurement. Another method is the Brinell hardness test, which uses a hardened steel or tungsten carbide ball indenter to create an indentation on the coil's surface. The diameter of the indentation is measured, and the hardness value is calculated using a formula that considers the applied load and indentation diameter. On the other hand, the Vickers hardness test utilizes a pyramidal diamond indenter to create an indentation on the coil's surface. The lengths of the indentation diagonals are measured, and the hardness value is calculated using a formula that takes into account the applied load and diagonal lengths. In addition to these traditional methods, modern technology has introduced non-destructive testing techniques such as ultrasonic testing and eddy current testing. Ultrasonic testing involves transmitting ultrasonic waves through the coil and measuring the time it takes for the waves to return. Changes in the wave pattern can indicate variations in hardness. Eddy current testing, on the other hand, uses electromagnetic induction to detect changes in electrical conductivity, which can be correlated to hardness variations in the steel coil. Overall, steel coils undergo thorough inspection using a combination of traditional and advanced techniques to ensure their hardness meets the required specifications. These inspections are vital in maintaining the quality and dependability of steel products in various industries.

- Q: Can steel coils be coated with phosphorescent materials?
- Yes, steel coils can be coated with phosphorescent materials. The phosphorescent coating can be applied to the surface of the steel coils, allowing them to emit a glow in the dark or low-light conditions.
- Q: How are steel coils processed before being used in manufacturing?
- Steel coils undergo several processing steps before they are used in manufacturing. The first step is to uncoil the steel coil, which involves unwinding it from a large spool. This is usually done using a machine called a decoiler. Once the coil is uncoiled, it is inspected for any defects or damages. After inspection, the steel coil goes through a process called leveling. This process involves passing the coil through a series of rollers to remove any unevenness or waviness in the steel. Leveling ensures that the coil has a uniform thickness and flat surface, which is crucial for further processing. The next step is to clean the steel coil to remove any impurities, such as rust, oil, or dirt. This is usually done by running the coil through a cleaning line, where it is treated with chemicals and water sprays. The cleaning process ensures that the surface of the coil is free from contaminants, which can affect the quality of the final product. Once the coil is cleaned, it may undergo additional processes depending on the specific requirements of the manufacturing process. For example, the coil may be annealed to improve its ductility and reduce its hardness. Annealing involves heating the coil to a specific temperature and then slowly cooling it. This process helps to relieve internal stresses and improve the steel's mechanical properties. After all the necessary processing steps are completed, the steel coil is ready to be used in manufacturing. It can be further processed into various shapes and forms, such as sheets, plates, or strips, depending on the specific requirements of the manufacturing process. These processed steel coils are then used in a wide range of industries, including automotive, construction, appliances, and machinery.
