Q:911 conspiacy theorists. Can fire melt steel?: So does fuel also generate timed explosions that were heard by firemen? Why do we see melting steel that looks like thermite burning? Does the jet fuel also destroy the entire 80 stories of steel support structure as well? (This is required to account for the free-fall speed of the collapse of three buildings. That's right, three buildings collapsed at near free-fall speeds in NYC in the WTC complex.) The government's conspiracy theory is totally inconsistent with the facts. The only theory that has coherence at the moment is the demolition theory presented by Professor Steven Jones of BYU (Physics). I've seen no credible challenges to the 13 points he presented in an academic paper on this topic. I'd very much like to see a credible explanation for the free-fall collapse of all three buildings.

Q:I have one and need info about it??....It has a wooden case around the steel necks.and 20 strings,Twin Tens.: well, it was made sometime before 1981, because that's when Fender quit making 10 string steel guitars. Without any more information than what you've given me, it could be the Pedal 2000, the PS210, or the Artist Dual 10. Fender made steel guitars from the 1950s through 1981, so it could be from any time in there. I hope you have the pedals with it. The 10-string and dual 10-string models were quite expensive in their day. Unfortunately, if you're thinking of reselling it, you're probably not going to get a lot of money for it unless you find a pedal steel player, and like I said, having all the pedals is very important in that case. Anyway, hope this helped. Good luck. If I were you I'd learn to play it. Pedal steel players are always in demand.

Q:How are steel coils inspected for coil set?: Various methods and equipment are utilized to inspect steel coils for coil set. Coil set refers to the curvature or shape of the coil, which can affect its performance and usability in different applications. One way to inspect steel coils for coil set is through visual examination. Experienced operators or inspectors carefully assess the coils for any visible deformities or irregularities in their shape. This can be accomplished by unrolling a section of the coil and checking for signs of buckling, twisting, or unevenness. Visual inspection is a simple and cost-effective method to identify evident coil set issues. In addition to visual examination, more advanced techniques are employed to accurately measure and quantify coil set. One such technique involves using a straight edge or template. The straight edge is placed along the length or width of the unrolled portion of the coil, and any gaps or deviations from the straight edge indicate the presence of coil set. This method provides a more precise measurement of the extent and severity of the coil set. Another commonly used technique is the utilization of specialized tools like a non-contact laser measurement system. This system projects a line onto the surface of the coil using lasers and measures the distance between the line and the coil. Any variations in this distance indicate the presence of coil set. This method offers high accuracy and provides detailed data on the coil's shape and curvature. Other methods may involve the use of mechanical devices such as rollers or tensioners to unroll and measure the coil's shape. These devices exert controlled pressure on the coil to straighten it out, and any resistance or deviations encountered during the process serve as indications of coil set. Overall, the inspection of steel coils for coil set involves a combination of visual examination and precise measurement techniques. These methods aid in identifying and quantifying any deformities or irregularities in the coil's shape, enabling manufacturers and customers to make informed decisions about the usability and quality of the steel coils.

Q:the comparison needed between other steel: *Mild steel is ductile and can be easily machined. Generation of heat is less than that of steel machining.So, the tool can have better life and you can do more machining. Cost factor is of prime importance as other steel are more costly than Mild steel. Mild steel, a grade of steel that does not harden when heated and chilled with cold water, so further machining can be easy. Mild steel is easily available.You will find it in your scrape yard. No need to change the tool repeatedly and no special tools are required for machining. Above is the comparisation between alloy steel,SS and superalloys. Cutting speed and feed does not required special skills.

Q:How are steel coils inspected for color consistency using colorimetry?: Colorimetry is a method used to inspect steel coils for color consistency. This involves quantifying and measuring colors using specialized instruments like spectrophotometers or colorimeters. These instruments measure the hue, saturation, and brightness of the steel coil's color. A colorimeter is typically used to inspect steel coils for color consistency. This device emits light onto the surface of the coil and measures the amount of light reflected back. The reflected light is then analyzed and compared to a known standard color to identify any deviations. To measure color, the colorimeter breaks down the reflected light into different wavelengths and quantifies the intensity of each wavelength. This data is then converted into numerical values that represent the color of the steel coil. These numerical values can be compared to a predefined color standard to determine if the coil's color falls within an acceptable range. To ensure accurate and consistent color measurement, colorimetry relies on standardized color spaces like CIE L*a*b* or CIE RGB. These color spaces define specific ranges of colors. By using these standardized color spaces, colorimeters can provide objective and reliable measurements of color consistency. Color consistency is particularly important for industries like automotive or appliance manufacturing, where the appearance of the final product is crucial. By inspecting the color of steel coils using colorimetry, manufacturers can ensure that the final products have a consistent and visually appealing appearance. In conclusion, colorimetry is an effective method for inspecting steel coils for color consistency. By using specialized instruments and standardized color spaces, manufacturers can accurately measure and compare the color of steel coils to predefined standards, ensuring that the final products meet the desired color specifications.

Q:What are the advantages of using steel coils in the manufacturing industry?: There are several advantages of using steel coils in the manufacturing industry. Firstly, steel coils provide excellent strength and durability, making them ideal for applications that require high load-bearing capacity. Secondly, steel coils are highly resistant to corrosion, making them suitable for outdoor or harsh environments. Additionally, steel coils offer consistent and uniform properties, ensuring reliable and precise manufacturing processes. Moreover, steel coils can be easily formed and shaped, allowing for versatile use in various industries. Lastly, steel coils are recyclable, making them an environmentally friendly choice.

Q:How are steel coils welded together?: Different methods can be employed to weld steel coils together, depending on the specific requirements and the type of steel being used. Electric resistance welding (ERW) is a common method where an electric current is utilized to generate heat in the coils, melting their edges. Pressure is then applied to join them together. ERW is a cost-effective and speedy technique for welding steel coils. Thinner steel coils are often welded using high-frequency induction welding (HFIW). This involves the use of an induction coil to produce an alternating magnetic field, inducing an electric current in the coils. The resistance of the coils to this current generates heat, causing the edges to melt and form a weld. For thicker and heavier steel coils, submerged arc welding (SAW) is commonly employed. This technique utilizes a granular flux and a continuous electrode that is fed into the weld area. The flux melts, creating a protective shield for the weld pool, while the electrode melts to form the weld. SAW is a robust and efficient method for welding steel coils. In addition to these methods, laser welding and gas metal arc welding (GMAW) can also be utilized for welding steel coils. Laser welding offers high precision and speed, while GMAW, also known as MIG welding, utilizes an electric arc between a consumable wire electrode and the steel coils to create a weld. Irrespective of the welding method employed, successful welding of steel coils hinges on proper edge preparation, maintenance of appropriate heat and pressure levels, and the use of correct welding techniques.

Q:I work in a steel foundry 10-12 hours a day where we melt and pour stainless steel tubes. The pour temperature for some of them is very close to the boiling point of stainless steel (about 3800 degrees) because it has to be VERY liquid for the application we use it. Anyway, it does boil a little and we breath in the vapours which I can assure you ARE indeed vapourized stainless steel (it collects and cools on everything and makes a nice shiny coating). Ok, so to the question, does breathing vapourized stainless steel all day pose a health risk such as cancer? Anyone know? I'm just curious.: I would imagine it's not good. I doubt cancer but I suppose it may be possible. Shouldn't you guys have respirator gear on? Where's OSHA when you need'em? ;)

Q:What are the different methods of coil recoiling for narrow strip widths?: Some of the different methods of coil recoiling for narrow strip widths include slitting and rewinding, oscillating winding, and turret winding.

Q:What are the different types of steel coil loading and unloading devices?: There are several types of steel coil loading and unloading devices, including coil carriages, coil lifters, coil turners, coil grabs, and coil tilters. These devices are designed to safely and efficiently handle steel coils during the loading and unloading process, ensuring smooth operations in various industries such as manufacturing, construction, and transportation.
