- Q: Molton is formed at 2800 F. Thats a fact. Now jet fuel at its hottest is 1800. Where does the other 1000 degress come in? And it was found at the WTC 7 site. Was this hit by a plane? A simple fire COULD NOT produce molton. This is a fact. Molton is formed during controlled demoliton of a building since all the bombs in the buiding go off and its very very hot. The fact there was MOLTON at the site is shocking to some since it is IMPOSSIBLE for molton to form from jet feul alone. Impossible. It needed another source. Now the claim that I'll get is that it weakened the stell but then we would find weak steel not molton. Why do you seem to throw this off of your shoulder? Do you not want to belive it? I'm no jet fuel guy but I know you cannot make molton by using just jet fuel. This is really proof that 9/11 was an inside job.
- I think there are things that you are missing here. First of all I looked up the MSDS sheet for Steel from US Steel. Steel is made of all kinds of different metals to start with and the melting/freezing point for steel is 1750 F not 2800 according to US Steel. In addition in the World Trade Center buildings there were all kinds of other materials that are normally used in construction that were all burning at the same time which would have added to the temperatures. Not only was it steel but it was iron, calcium and other building materials too. NIST provides a maximum gas temperature due to WTC fires of 1,000 °C: In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, figure 6-36) Okay I don't know if you know who NIST is but that is the National Institute of Standards and Technology and they are some pretty smart people. They did not say that the steel melted due to the fires, but they did say that the temperatures surely did get high enough to to melt the steel. If US Steel says the melting point for steel is 1750 and NIST says that the temperatures were around 1800 F then that is high enough to melt the steel. I think the key is that there were other materials burning too.
- Q: How are steel coils used in the production of steel hooks?
- Steel coils are used in the production of steel hooks by being shaped and cut into the desired hook shape. The coils are uncoiled and fed into a machine where they undergo various processes such as bending, shaping, and welding to form the hooks. The strength and durability of the steel coils contribute to the quality and reliability of the final steel hooks.
- Q: How are steel coils used in the manufacturing of construction equipment?
- Steel coils are used in the manufacturing of construction equipment as they serve as a primary raw material for the fabrication of various structural components such as frames, bodies, and chassis. These coils are typically processed through cutting, bending, welding, and shaping techniques to create the necessary parts that provide strength, durability, and stability to construction machinery.
- Q: How are steel coils inspected for chemical composition using spectroscopy?
- Spectroscopy techniques such as X-ray fluorescence (XRF) and laser-induced breakdown spectroscopy (LIBS) can be employed to examine the chemical makeup of steel coils. XRF involves directing an X-ray beam onto the surface of the steel coil, prompting the sample's atoms to emit distinct X-ray fluorescence radiation. By examining the energy and intensity of these emitted X-rays, one can determine the elemental composition of the steel. This method is both rapid and non-destructive, enabling swift and accurate assessment of the steel coil's chemical composition. On the other hand, LIBS entails focusing a laser beam onto the steel coil's surface, generating a high-temperature plasma. The plasma emits light, which is subsequently collected and analyzed using a spectrometer. This emitted light contains characteristic atomic and ionic emissions, allowing for the identification and quantification of various elements present in the steel. LIBS is also a non-destructive technique, providing real-time results and requiring minimal sample preparation. Both XRF and LIBS offer multiple benefits in terms of speed, non-destructiveness, and user-friendliness for inspecting the chemical composition of steel coils. These spectroscopic techniques play a vital role in quality control and assurance, ensuring that the steel meets the necessary specifications and standards for diverse industrial applications.
- Q: The difference between aluminized color steel roll and ordinary color steel roll
- Ordinary color steel roll is a composite material, also known as color coated steel plate, is used in the continuous production line on the production line after surface degreasing, phosphating and other chemical coating treatment, painted with organic coatings, made by baking products. Both steel and organic materials are a little bit different. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance.
- Q: When I took guitar lessons, I found that the Nylon strings are easier for me, but I love the sound of steel strings. Now, I have my own acoustic guitar, and 2 strings broke off, so I'm getting strings today. I'm not sure if Nylon strings would 'fit' on my guitar, and it's to soft of a noise. But the steel are much better sounding, but it's a little bit harder to push the string down on the fret. Which do you prefer, why?(:
- classical guitar = nylon strings Acoustic/electric = steel strings Firstly i must explain you that fingerstyle playing on guitar is using your nails to play and not the soft spot on the acre of your fingers... Why? Because nails produce a cleaner, better and louder sound while the soft spot Is sloppy and dusty... (very simplistic)The difference with using a pick is that you can use your fingers as 4 different picks instead the one you are using when playing with a pick... Well the reason is that nylon strings aren't supposed to be played with a pick but with fingers (nails in reality as mentioned already) if you want το keep them in good condition for long(the sound they provide is another thing and it's a matter of taste) Steel strings are better for using with a pick... Probably a classical guitarist would easily break or harm his nails while playing on steel strings.... Personaly i like both... Depends on what playing
- Q: What are the different surface treatments for steel coils?
- There are several different surface treatments available for steel coils, depending on the desired outcome and application. Some of the most common surface treatments for steel coils include: 1. Hot-dip galvanizing: This process involves immersing the steel coils in a bath of molten zinc, which forms a protective layer on the surface of the steel. Hot-dip galvanizing provides excellent corrosion resistance and is often used for outdoor applications. 2. Electro-galvanizing: Similar to hot-dip galvanizing, but instead of immersing the steel coils in molten zinc, a thin layer of zinc is electroplated onto the surface of the steel. Electro-galvanizing provides good corrosion resistance and is commonly used for indoor applications. 3. Powder coating: This process involves applying a dry powder to the surface of the steel coils, which is then heated and cured to form a hard, durable coating. Powder coating provides excellent corrosion resistance and is available in a wide range of colors and finishes. 4. Paint coating: Steel coils can also be coated with a liquid paint, which provides both corrosion resistance and aesthetic appeal. Paint coatings can be applied in various thicknesses and finishes, depending on the desired look and level of protection required. 5. Phosphating: Phosphating is a chemical treatment that involves immersing the steel coils in a phosphate solution. This process creates a thin, adherent layer of phosphate on the surface of the steel, which enhances paint adhesion and improves corrosion resistance. 6. Chromate conversion coating: Also known as chromating or passivation, this process involves immersing the steel coils in a solution containing chromium salts. Chromate conversion coatings provide excellent corrosion resistance and also act as a primer for subsequent paint or powder coating. 7. Zinc-nickel plating: This surface treatment involves electroplating a layer of zinc-nickel alloy onto the steel coils. Zinc-nickel plating provides superior corrosion resistance compared to pure zinc plating and is often used in demanding environments. These are just a few of the many surface treatments available for steel coils. The choice of treatment depends on factors such as the application, desired level of corrosion resistance, aesthetic requirements, and budget. It is important to carefully consider the specific needs of the project and consult with experts to determine the most suitable surface treatment for steel coils.
- Q: How did the growth of the steel industry influence the development of other industries?
- At least three ways: 1. Steel as a material that other industries could use to do things that couldn't be done before (for example, construction (skyscrapers, long bridges, etc.)) or could now be done at much lower cost and hence increased the size of the industry (automobiles, bearings, etc.)
- Q: I'm ordering a Pair of tongs(a tool used to dig quahogs in bays that scrapes the bottom constantly) and what type of metal would be the best to fabricate it, steel or stainless steel?
- Whilst doing a welding course a few years ago the teacher said stainless steel was not its proper name,it is called Heat and Corossion resistant steel,it come in different grades related to its corossion resistance,priced accordingly.Must be welded properly without introduction of carbon to the weld (carbon pickup) or the weld might not be there next time you look dependant on environment.Generally harder to form than mild steel (low carbon steel) so it will tend to be stronger than lcs for the same cross section.steve
- Q: How are steel coils packaged for shipping?
- Steel coils are typically packaged for shipping by being tightly wound and secured with steel bands or straps. They are then placed on wooden pallets or in steel cradles to ensure stability during transportation. Additionally, protective packaging materials such as plastic or cardboard may be used to prevent damage from moisture, dust, or other external factors.
