- Q:911 conspiacy theorists. Can fire melt steel?
- They can't melt that fast At that temperature, the fire caused by the jet's fuel didn't hot enough to melt the concrete steel. As you see in the video the flame took only 20 minutes. The heat is not fast enough to penetrate all fragment of the concrete steel from top to the foundation, steel is not a good heat conductor like the iron. The explosion only took 5 stories, even all flame in all stories will take 4 hours to melt the core - in this case the core is the worst quality alloy which I don't think is used by WTC. The speed of the falling of WTC building was way too fast. It only took about 9.5 seconds. As an illustration, we throw an object - no matter the weight from the top of WTC, let's count how long it takes from the top to the ground as easy as senior high physics. We took the height of as h = 526.3 m, the gravity 9.8 m/s^2 then apply them to the Newton's equations, h = 1/2*g*t^2 then t = sqrt(2*h/g) = sqrt(526.3/9.8) = 7.32 seconds. The difference is just 2.2 seconds. The resistance of the concrete and solid materials should give at least 200% of the fall duration. WTC's 9.5 secs to fall is even faster a ball sliding on its wall from top the ground. I don't know what happened there. But my Basic Physics lecturer at first grade in my college -who concentrates in Materials- said that it is very odd that the flame burning 5 stories (at most 2% of 110 stories WTC) took only 20 minutes to melt the core of 30% after explosion top stories' core. A friend of mine, got summa cumlaude Bsc in civil engineering - concentrated in structure, said that the pan cake fall has never occured before due to fire causes. If the heat is hot enough to melt the core then the building should bend forward at a broad angle because the strain caused by the heat is not uniformly distributed along the building's core - remember steel is not a good heat conductor. I'm not speculatiing, but 9/11 is an odd tragedy
- Q:What are the common coil transportation options?
- The common coil transportation options include trucking, rail transport, and sea freight.
- Q:How are steel coils used in the production of storage racks and shelving?
- Steel coils are a crucial component in the manufacturing process of storage racks and shelving. These coils are typically made from high-quality steel that is rolled into a long, continuous strip. The steel coils are then processed and transformed into various forms, such as sheets or strips, which are used to create the frames, shelves, and other structural components of storage racks and shelving systems. Firstly, the steel coils are unwound and flattened through a series of machines, ensuring uniform thickness and width. This process enables manufacturers to obtain sheets or strips of steel with consistent dimensions, which are essential for the production of storage racks and shelving that need to meet specific design specifications and structural requirements. Once the steel coils are flattened and cut into the desired sizes, they are further processed to add necessary features and characteristics. This can involve bending, punching, or welding the steel to create the desired shapes, such as uprights, beams, or brackets for the storage racks and shelving. These components are then assembled together to form the framework of the storage system. The durability and strength of steel make it an ideal material for storage racks and shelving. Steel coils provide the necessary structural integrity and load-bearing capacity required to support heavy items and withstand the rigors of everyday use. Additionally, steel is resistant to corrosion, which ensures the longevity and reliability of the storage racks and shelving systems. Furthermore, steel coils can be coated or galvanized to enhance their resistance to rust and corrosion. This protective layer helps to maintain the aesthetic appeal and structural integrity of the storage racks and shelving, especially in environments with high humidity or exposure to moisture. In summary, steel coils play a vital role in the production of storage racks and shelving. They provide the raw material from which various components are fabricated, ensuring the strength, durability, and load-bearing capacity necessary for these storage systems. The versatility and adaptability of steel allow manufacturers to create storage racks and shelving that meet specific design requirements and offer long-lasting storage solutions for a wide range of applications.
- Q:What are the common transportation defects in steel coils?
- Steel coils can experience various transportation defects. Improper handling or securing during transportation is a major cause of coil damage, resulting in dents, scratches, or tears in the steel. Coil edge damage is another issue that arises when the coils lack proper protection or rub against each other during transit, leading to deformation or breakage of the edges. Additionally, coil shifting occurs when the coils are inadequately secured or braced, causing them to move and shift during transportation, potentially causing misalignment or damage. Moreover, coil corrosion is a prevalent defect that arises when the coils are exposed to moisture or corrosive elements during transportation, leading to rust and deterioration of the steel. To prevent these common transportation defects in steel coils, it is essential to implement appropriate handling, securing, and protection measures.

- Q:What are the common coil coating materials?
- The common coil coating materials include polyester, polyurethane, polyvinylidene fluoride (PVDF), silicone polyester, and epoxy.
- Q:How are steel coils processed for cutting to length or blanking?
- Steel coils are processed for cutting to length or blanking through a series of steps. First, the coils are uncoiled and straightened to remove any bends or twists. Then, they are fed through a machine that measures and marks the desired length or shape. Next, a cutting tool or die is used to precisely cut the steel into the required dimensions. Finally, the cut pieces are inspected for quality and packaged for shipment.
- Q:How are steel coils used in the production of steel wire?
- Steel coils are used in the production of steel wire by being unwound and fed into a wire drawing machine. The coils provide a continuous and consistent supply of steel, which is passed through a series of dies to reduce its diameter and increase its strength. This process is repeated multiple times until the desired wire diameter is achieved.
- Q:How are steel coils coated for added protection?
- Steel coils are coated for added protection using a process called coil coating. This process involves the application of a protective layer onto the surface of the steel coil to enhance its durability and resistance to corrosion. There are various methods used to coat steel coils, but the most common one is the continuous coil coating process. In this process, the steel coil is unwound and cleaned thoroughly to remove any contaminants or impurities from the surface. This ensures proper adhesion of the coating material. Once the steel coil is cleaned, it is then pre-treated to enhance its surface properties. This pre-treatment typically involves applying a chemical solution or a conversion coating to the surface of the coil. The purpose of this step is to create a receptive surface for the coating material and enhance its adhesion. After the pre-treatment, the steel coil is coated with a protective layer. This coating material can be a liquid paint, a powder coating, or sometimes a combination of both. The coating is applied uniformly onto the surface of the coil using various techniques, such as roll coating, spray coating, or electrostatic coating. Once the coating is applied, the steel coil is cured or dried using heat or sometimes ultraviolet light. This curing process ensures that the coating material forms a strong bond with the steel surface and achieves the desired protective properties. The coated steel coil is then inspected for quality control measures, such as thickness, adhesion, and appearance. If it meets the required specifications, it is further processed, which may involve cutting, slitting, or forming into the desired shape or size. Overall, the process of coating steel coils for added protection involves thorough cleaning, pre-treatment, application of a protective coating, curing, and quality control. This ensures that the steel coils possess excellent resistance to corrosion, abrasion, and other environmental factors, making them suitable for a wide range of applications in various industries.
- Q:What is the average shelf life of a painted steel coil?
- The average shelf life of a painted steel coil can vary depending on various factors such as the quality of the paint, environmental conditions, and storage methods. However, on average, a well-maintained painted steel coil can have a shelf life of 10 to 20 years.
