Q:I have a tiara and it oxidized and I'm not sure what material it is. I know it it isn't metal so i was wondering if is steel? Also if it's steel, can I do something to clean it?

Yes - Steel can oxidize, its most commonly called rust Steel is a metal. Depending on the level of oxidation, you might be able to polish it with very fine steel wool. If is is really bad, then you might need a chemical cleaner such as Naval Jelly, which can be found at the hardware store. But the Naval Jelly might discolor the metal, so then you might need to polish it afterward to return its finish.

Q:Steel used to be made in the #92;Bessemer Converter, write about how steel making processes today produce better quality steel????

Steel making today is a faster process as use Blast furnace which Coke Limestone Iron ore are fed into the top of the furnace. after these are fed in a exothermic happens and converts these ores into Iron. Iron is not strong enough to be used in thing this is formally known as pig iron. To convert Iron ore into steel it has to go to a process called the BOS Basic Oxygen Steel-making were oxygen is blown onto the iron ore for about 30 to 45 min and this then turns it into steel as all the impurities are taken out and this floats on top and known as slag and used for things such as road building. Once you have steel this is then pored into ladles and taken to the continuous caster and rolled into slabs, billets and bars and then cut off and rolled into a finished products and then taken to compniaes to be made into thins you see made out off metal such as skyscrapers. Hope this helps :o)

Q:How are steel coils used in the production of power generation equipment?

Steel coils are used in the production of power generation equipment as they are shaped and formed into various components such as turbine casings, generator frames, and steam pipes. These coils provide the necessary strength and durability to withstand the high temperatures, pressure, and mechanical stresses involved in power generation processes. Additionally, steel coils are often coated with protective layers to prevent corrosion, ensuring the longevity and reliability of the equipment.

Q:Is there any way to melt steel without the intense heat of a blast furnace?

How To Melt Steel

Q:7850kg/cu.m density is typical for all type of steel? like reibar, I- beam and so on

90% of the steels used today are plain mild carbon steels consisting of iron with less than 1% carbon content and as such have a density of about 7750 kg/cubic meter. Some special steels which have a significant percentage of alloying elements such as chrome or manganese or other elements will have greater density bringing the steel up to about 8000 kg / cubic meter. There are a greater many factors influencing the exact density of a steel. Even for steels of exactly the same content of iron , carbon and other alloying elements, there may be a difference ( very small mind you ) in density due to work hardening. The difference in this case is due to movement of dislocations which become locked in the grain boundaries and this forms a more dense crystal structure. For this same reason, the theoretical density of steel (which does not take into account dislocations) is greater than the measured density of steel.

Q:Why is iron used to create steel? Why not other elements?

iron came before steel. iron is what was discovered that, under certain circumstances, became a stronger metal: steel. that is why. its like asking why copper is in bronze. because what we call bronze, is an alloy of copper and tin. if you give a more detailed question, i may be able to give a more detailed answer.

Q:How are steel coils inspected for paint adhesion using adhesion testers?

Paint adhesion on steel coils is systematically and rigorously inspected using adhesion testers. These testers are specifically designed devices for assessing the bond strength between the paint and the underlying steel surface. To begin the inspection process, representative samples are selected from the steel coils. These samples are typically cut into smaller sections to ensure they are free from defects or surface irregularities that could impact the adhesion test results. Once the samples are prepared, the adhesion testers are utilized to measure the force needed to detach the paint coating from the steel surface. The most commonly used adhesion tester is the cross-cut adhesion tester. It consists of a set of blades arranged in a grid pattern, which are employed to create cuts through the paint coating, forming a grid of squares or rectangles down to the steel surface. After the cuts are made, a specialized tape is applied to the grid area and pressed firmly onto the surface. The tape is then rapidly pulled off at a 90-degree angle to the surface, and the force required for the paint coating's removal from the steel is measured and recorded. The results of the adhesion test are evaluated based on predetermined standards or specifications. These standards typically define the minimum acceptable adhesion strength for the specific application or industry. If the measured adhesion strength falls below the specified threshold, it indicates poor paint adhesion, which could result in issues like paint delamination or corrosion. Along with the cross-cut adhesion tester, other adhesion testing methods may also be utilized, such as the pull-off adhesion tester. This method involves a hydraulic or mechanical device applying a tensile force to a small circular or dolly-shaped test area. The force required to pull off the dolly is measured and used to assess the paint adhesion. In summary, the use of adhesion testers ensures a thorough inspection of paint adhesion on steel coils. This process helps in early identification of potential adhesion issues, enabling appropriate remedial measures to be taken to ensure the durability and performance of the paint coating.

Q:Ok, so im gonna get my tragus pierced and i was wondering which is better, titanium or stainless steel. I hear like everyone uses stainless steel , but is titanium better?Thanks

It seems like less people are allergic to titanium than surgical grade steel.

Q:How are steel coils used in the manufacturing of household appliances?

Steel coils are used in the manufacturing of household appliances as a raw material for forming various components such as panels, frames, and structures. The coils are typically cut, shaped, and welded to create the necessary parts used in appliances like refrigerators, stoves, and washing machines. The durability and strength of steel make it an ideal material for ensuring the longevity and performance of these appliances.

Q:What is the process of galvanizing steel coils?

Enhancing the durability and protecting steel coils from corrosion involves a series of steps in the galvanization process. To begin, the steel coils undergo a thorough cleaning to eliminate any dirt, oil, or impurities on the surface. This is achieved through an acid pickling process, where the coils are immersed in a diluted acid solution or treated with a chemical cleaner. The aim is to ensure the surface of the coils is free from contaminants, allowing for better adhesion of the zinc coating. Following the cleaning process, the coils are rinsed to remove any remaining acid or cleaner, preventing adverse reactions in the next stage. The subsequent step involves the actual galvanization, where the cleaned coils are submerged in a bath of molten zinc. To guarantee an even coating, the coils are carefully passed through the zinc bath using rollers or other mechanisms. The zinc bath is maintained at a specific temperature, typically around 450°C (842°F), enabling the molten zinc to bond with the steel surface. Upon withdrawal from the zinc bath, excess zinc is eliminated by passing the coils through air knives or by centrifugal spinning. This ensures control over the thickness of the zinc coating, resulting in a uniform appearance. Once the galvanization process is complete, the steel coils are gradually cooled to room temperature. This facilitates the solidification and firm bonding of the zinc coating with the steel surface, creating a protective barrier against corrosion. The final step involves inspection and quality control. The galvanized steel coils are carefully examined for any defects, such as uneven coating or areas with insufficient zinc coverage. This inspection is typically conducted visually or using specialized equipment capable of detecting anomalies. Additionally, the coating thickness is measured to ensure it meets the required specifications. In conclusion, the galvanization process for steel coils is designed to enhance their longevity and shield them from rust and corrosion. By applying a layer of zinc coating to the steel surface, the coils become more resistant to environmental factors, making them suitable for a wide range of applications across various industries.
