Q: How are steel coils processed and shaped into specific products?: The production of specific steel products involves a series of steps and techniques using different machinery. Initially, steel coils are unwound and flattened using a decoiler and a leveller. This prepares the coils for further processing. Next, the flattened coils are fed into a rolling mill where they undergo cold rolling. This process involves passing the coils through rollers to reduce thickness, improve surface finish, and enhance strength and hardness. After cold rolling, additional processes like annealing or galvanizing may be applied depending on the desired properties of the final product. Annealing involves heating the coils to a specific temperature and slowly cooling them to relieve internal stresses and improve ductility. Galvanizing, on the other hand, involves coating the coils with a layer of zinc to protect against corrosion. Once these treatments are completed, the steel coils are ready to be shaped into specific products. This can be achieved through cutting, stamping, or forming. Cutting involves trimming the coils into desired sizes or lengths using shears or lasers. Stamping involves using a die and press to shape the coils into intricate designs or patterns. Forming, on the other hand, involves bending or shaping the coils with specialized machinery to create curved or contoured products. Finally, the shaped steel products are inspected for quality and undergo any necessary finishing processes like painting or coating. This ensures that the products meet required specifications and are ready for distribution or further assembly. In conclusion, the transformation of steel coils into specific products involves a combination of steps including unwinding, flattening, cold rolling, annealing or galvanizing, cutting, stamping, forming, inspection, and finishing. Each step is essential in producing high-quality steel products used across various industries.

Q: How are steel coils inspected for dimensional accuracy after processing?: Steel coils are inspected for dimensional accuracy after processing using various methods such as measuring tape, calipers, laser scanners, or automated vision systems. These tools allow for precise measurements of the coil's width, thickness, and length, ensuring that it meets the required specifications.

Q: What are the different types of steel surface finishes for coils?: There are several types of steel surface finishes for coils, including hot rolled, cold rolled, galvanized, coated, and pickled and oiled.

Q: What are the common uses of stainless steel coils?: Stainless steel coils are commonly used in a variety of industries for applications such as manufacturing automotive parts, appliances, construction materials, and HVAC systems. They are also utilized in the production of kitchen utensils, medical equipment, and food processing machinery due to their corrosion resistance, durability, and heat resistance properties.

Q: They are showing on tv a special on how the new World Trade Center, building 1, is being built. Focusing on the steel and the guys fitting everything together.Where do builders go to buy all that steel framing? We do not build really tall buildings where I live so most of the steel is cut and welded on the job site. At World Trade Center 1, they seem to get the steel on trucks; already cut and welded.: The steel is all custom fabricated in what are called structural steel fabrication shops. Each Building is designed by architects then the frame is designed by engineers to support whatever load is being applied to the building. After the engineering is done it goes out for a bid package where a fab shop estimates how much to charge for the fabrication of the steel and the erection of the steel. Once a company wins the bid, it then has to design how the steel will connect with one another and have it approved by an engineering firm to assure the connections are strong enough. Once all of that happens the fab shop orders raw steel beams and angle iron and steel plate at stock lengths. Beams are then cut into the right length and holes drilled in the proper places. The beam is then marked with a number that tells the erectors where it goes. The steel is then shipped out in batches to the construction site where it is unloaded and shook out into an organized place to grab them with a crane. They are then put together like a toy model, there are instructions that say what beam goes where and what size bolt to use. The welding you see being done is on really critical moments that need extra strength. That is about how it goes in a nutshell. It is a bit more complicated than that but it gives you an idea.

Q: Is it faster to smith steel or mithril in Rinescape assuming I'm going to mine everything myself?Mining level: 76Smithing level: 55: i think steel would be better since there isn't a lot of mithril ore and it would take a lot of time to mine it and it will take also 4 coals to make a mith bar and 2 only for a steel bar

Q: what is tool steel and does it function better than carbon or spring steel?: It depends on the tool steel you are referring to and the function of the sword. L6 steel is a modern tool steel that a few smiths are using (Howard Clark, MAS, etc.), which produces some amazing swords that are both tough and flexible, but very few smiths are qualified to work with it and it is easy to screw up the heat treatment. T10 is another tool steel used by a few larger manufacturers (Paul Chen, etc.), which has a very high carbon content and includes a tungsten ally which makes it very tough and a little more resilient then 1095 carbon steel, however, as with any very high carbon steel, they may be durable but may also chip or break. 1060 and 1075 is the standard steel for most modern production swords since they provide a good balance between hardness, and durability. Spring steel is good if you are concerned about a sword taking a lateral bend, but is only really necessary if you do a lot of tameshigiri and have not yet developed a consistent hasuji.

Q: Can you weld copper or brass to steel?: Copper cannot be welded to steel since copper has a significantly lower melting point than steel, and brass has an even lower melting point than copper. Therefore, traditional fusion welding processes would not work. It's possible to braze copper to steel using brass as a filler metal, but this is not usually done because of practical concerns. (For example, the melting point of zinc brass is close enough to that of copper, that it's hard to heat the joint to the melting temperature of the brass without also melting the copper.) Rather, it's common to braze copper to steel using silver-copper-zinc brazing alloys instead. These alloys have a lower working temp. than zinc brass. Copper-silver-phosphorus brazing alloys, or zinc-tin hard solder could also be used. Also, solid state welding methods can be used to join copper to steel, but this is limited to very special applications. Friction welding can be used to join copper pipes and/or shafts to steel ones. Explosion welding can be used to join a copper or brass sheet to a steel plate. Forge welding may be possible between copper and steel, but I don't know of any applications for this.

Q: I need to construct a table with three columns, which states the name of the steel, its compositions (e.g. Fe and C), and its special properties for a variety of different steel products.Help me please, a site with info would be great, explanations would be even better.: Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and form of their presence in the steel (solute elements, precipitated phase) controls qualities such as the hardness, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also less ductile. H.

Q: Search the internet for 'Frost Clipper Knife'. This knife comes in either stainless or carbon steel. I have a friend who has one (stainless steel) and he is very impressed with it, but I have heard that Carbon Steel blades are better? Discuss...: There are different grades of Carbon Steel. A good grade is much harder than Stainless Steel and will stay sharp longer. It is also many times harder to get an edge on than Stainless Steel. I have had both and prefer the Stainless Steel because eventually the Carbon Blade does get dull, and you will wear out a Whet Stone trying to put the edge back on it. The Stainless Steel holds an edge an acceptable amount of time and is easier to sharpen when the time comes. Putting either knife through a can opener sharpener will ruin the edge and make it almost impossible to put another edge on the knife. Look closely and determine the angel of the bevel, then lay the knife bevel flat on a good whet stone and try to take a thin slice off of the stone. Turn the knife over and do the other side so you keep the edge centered on the blade. Keep turning the knife over and taking thin slices until it is sharp. Dress with a good quality sharpening steel.
