Product Description
Brief Introduction
Cold Rolled Steel is steel that has been worked below its recrystallization temperature by passing it between a pair of rollers. Recrystallization temperature is the temperature at which grains in the lattice structure of the metal have been rearranged, leaving it free of strain and deformations. Cold Rolled Steel is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The Cold Rolled Steel is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the Cold Rolled Steel is further reduced, its strength and hardness both increase, but its ductility decreases. After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility. The final Cold Rolled Steel coil may be manufactured in the form of sheets, strips, bars, or other forms.

- Q: hi to every one I need to konw moer about steel and iron industry (process) thank you in advance for your intresting
- Steel is made from injecting air into molten iron
- Q: What are the different methods of coil welding for steel coils?
- Steel coils can be welded using various methods, each with its own pros and cons. The following are some commonly used techniques: 1. Resistance Welding: In this method, an electric current is passed through the coils to generate heat, which fuses the ends together. It is a fast and efficient process that produces reliable welds. Industries requiring high-speed production often utilize resistance welding. 2. Arc Welding: This technique involves creating an electric arc between an electrode and the workpiece to create a weld. It can be further categorized into processes like shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and flux-cored arc welding (FCAW). Arc welding offers good penetration and can be applied to a wide range of steel coils. 3. Laser Welding: Laser welding employs a high-powered laser beam to melt and join the ends of the coils. It provides precise control, high welding speeds, and minimal distortion. Industries such as automotive and electronics, which require precision and aesthetics, often rely on laser welding. 4. Induction Welding: This method involves using electromagnetic induction to heat the coils, which then melt and are pressed together to form a weld. It is suitable for thin-gauge steel coils and allows for precise control over the welding process. 5. High-Frequency Welding: High-frequency current is used to heat and weld the coils together in this technique. It is commonly used for pipes and tubes and offers high production rates and good weld quality. 6. Friction Welding: Friction welding creates a weld by generating heat through the rubbing of the coil ends. It is a fast and reliable method that produces strong joints. Industries requiring high-strength welds, such as automotive and aerospace, often employ friction welding. These are just a few of the many coil welding methods for steel coils. The choice of technique depends on factors like the steel type and thickness, required weld strength, production speed, and project requirements as a whole.
- Q: What are the common coil packaging materials?
- The common coil packaging materials include steel strapping, stretch film, polypropylene strapping, and HDPE (high-density polyethylene) sheets.
- Q: I have two guitars, a nylon stringed classical, and a steel stringed acoustic, I find the nylon strings easier to play, but doesn't have as good of sound as the steel stringed, and when I play with the steel strings, it really hurts my fingers, and if I play just a little bit, it feels like the high e string is going to cut my finger. Are the strings too high? What can I do to make the steel strings easier to play?
- Your steel-string acoustic should not be all that much harder to play than your nylon string acoustic. Classical guitars have stretchier strings, but they also normally have higher action (string height). It sounds like your steel-string may have a problem. A typical low action would be around 0.090 gap between the low E string and the top of the 12th fret, and 0.070 between the high E and the top of the 12th fret. If yours is a lot higher than that, having it professionally set up will probably help. If it's a very cheap guitar, replacement might be the best option. Why do you need to choose between classical and steel-string? You already own both.
- Q: Ok.. I was wondering if it's possible for me to recycle baked bean cans (steel)? And if so in Western Australia (that's where I live)?I love baked beans... and I also like skateboarding, so I thought if I kept my baked bean cans, that I could get them recycled somewhere and turn it into something I could skate on (rail, etc.). I'm just curious to know if all this is possible...Cheers. :)
- Most baked beans are cooked with pork and include a piece in the can. Depending on what kind of vegetarian you are, you could eat them and simply remove the piece of pork, or, Bush's has vegetarian baked beans which are obviously cooked without the meat seasoning. They are very good, and of course beans are an excellent and needed source of protein in a vegetarian diet.
- Q: I wrote in my assignment that mild steel has a high carbon content (4%).This is why it has its strong and rigid properties.. is this correct?
- High carbon steel is much harder than iron. In fact, steel -is- iron with carbon in it. Mild steel has a very low carbon content and is much softer. High carbon steel is much stronger after heat treatment. However, about 2% carbon, it is considered cast iron. Mild steel contains about 0.16% to 0.29% carbon content. It has a relatively low strength but is highly malleable.
- Q: What are the common coil storage conditions?
- The common coil storage conditions include keeping the coils in a dry and well-ventilated area, away from direct sunlight and extreme temperatures. It is also important to store the coils in an upright position, on pallets or racks, to prevent damage and ensure easy access for handling and transportation.
- Q: What are the weight ranges for steel coils?
- The weight ranges for steel coils can vary depending on the specific type and thickness of the steel. However, common weight ranges for steel coils typically range from a few hundred pounds to several thousand pounds.
- Q: What is the process of recoiling steel coils?
- The process of recoiling steel coils involves rewinding or unrolling large steel coils to create smaller, more manageable coils. This process is typically carried out in steel processing plants or coil service centers. The first step in the recoiling process is to identify the appropriate coil to be recoiled. This selection is based on factors such as coil size, weight, and quality. Once the coil is chosen, it is placed onto a recoiling machine, which is equipped with various mechanisms to facilitate the recoiling process. The recoiling machine consists of a mandrel or drum, around which the coil is wound or unwound. The coil is secured onto the mandrel, either by mechanical clamps or hydraulic pressure, to ensure it remains stable during the recoiling process. In the case of rewinding or recoiling a large coil into smaller coils, the machine starts by unwinding the original coil. This is done by rotating the mandrel in the opposite direction, causing the coil to gradually unroll. As the coil unwinds, it passes through various straightening and flattening mechanisms, which help to ensure the coils are produced with consistent dimensions and quality. Once the original coil is completely unwound, the machine starts the rewinding process. The smaller coils are created by winding the steel strip onto the mandrel in a controlled manner. The speed and tension of the rewinding process are carefully regulated to prevent any damage to the steel strip. During the recoiling process, various quality control measures are implemented to ensure the produced coils meet the desired specifications. These may include monitoring the thickness, width, and surface quality of the steel strip, as well as conducting periodic inspections to detect any defects or irregularities. Once the rewinding process is completed, the smaller coils are typically removed from the mandrel and prepared for further processing or shipment. This may involve applying protective coatings, labeling, or packaging the coils, depending on their intended use. In summary, the process of recoiling steel coils involves unwinding large coils, straightening and flattening the steel strip, and rewinding it onto a mandrel to create smaller, more manageable coils. This process requires specialized machinery and careful control to ensure the quality and consistency of the recoiled coils.
- Q: what is the porpose of preheating mild steel prior to welding
- ok dont listen to bob the builder down there, u preheat thicker steels to draw moisture out of them. take a propane torch to something exposed to just atmospheric air around 3 inches thick and the water will literally pour out of it. do u want that in ur weld? no. so u preheat to draw any moisture or contaminates out of the base metal. good luck.
