- Q:How are steel coils inspected for defects after recoiling?
- Steel coils are inspected for defects after recoiling by conducting visual inspections, using non-destructive testing methods such as ultrasonic testing or magnetic particle inspection, and conducting measurements to check for dimensional accuracy and straightness.
- Q:I was cutting a sheet of steel with an angle grinder when suddenly the rate at which the blade was cutting slowed way down. I tried a few different things, and turned off the tool and looked at the blade. It didn't look damaged, but it definitely was not cutting as quickly. I thought either I had hit a harder section of steel (is that possible? It looked pretty uniform) or the blade had lost it's abrasive quality or something. Also, before this happened I had accidentally cut into the wooden sawhorse that was holding up the steel sheet, but I've done that before with no problem. After a short while the problem fixed itself and the rate of cutting went back to a fast normal. Anyone know why this happened?
- Sounds like the abrasive surface got blinded, coated with something that prevented the abrasive particles from touching the steel. It is possible to have vastly different hardnesses in a single piece of steel. Case hardening, carburizing, induction hardening, heat affected zone from welding, differences in work hardening, and presence of inclusions are some of the things that can create hardness variation within a single piece. But... sounds like you are working with a sheet which is unlikely to have any of these conditions. So... it was probably the grinding disk
- Q:What are the challenges in coil edge trimming for narrow strips?
- There are several challenges in coil edge trimming for narrow strips. Firstly, one of the main challenges is maintaining accuracy and precision during the trimming process. Narrow strips require a high level of precision to ensure that the edges are trimmed evenly and smoothly. Any deviation from this precision can result in uneven edges or burrs, which can affect the overall quality of the strip. Secondly, there is the challenge of controlling the strip tension. Narrow strips are more prone to tension issues, as they have less surface area to distribute the tension evenly. This can lead to problems such as strip breakage or stretching, which can impact the final product's quality. Another challenge is avoiding material waste. Narrow strips often have a smaller margin for error, meaning that any mistakes in the trimming process can result in a significant amount of wasted material. Minimizing material waste is crucial for cost-effectiveness and sustainable manufacturing practices. Additionally, maintaining a high production rate can be challenging when working with narrow strips. The trimming equipment needs to be able to handle the high speed required for efficient production while still maintaining accuracy and precision. This requires the use of advanced machinery and technology to ensure smooth and efficient operations. Lastly, the handling and transportation of narrow strips can also pose challenges. Due to their small size, narrow strips are more susceptible to damage during handling and transportation. Proper care and handling techniques need to be implemented to prevent any potential damage, which could affect the quality of the final product. Overall, the challenges in coil edge trimming for narrow strips revolve around precision, tension control, material waste, production rate, and handling. Overcoming these challenges requires the use of advanced technology, skilled operators, and careful attention to detail throughout the entire process.
- Q:How are steel coils used in the manufacturing of railroads?
- Steel coils are used in the manufacturing of railroads to produce rails, which form the tracks that trains run on. These coils are rolled into long, straight sections and then shaped into the required rail profile. The rails are then cut to the desired length and undergo various processes, such as heat treatment and finishing, to enhance their strength and durability. Overall, steel coils are a crucial raw material in the creation of reliable and robust railroad infrastructure.
- Q:I just want to know why is cold steel katana a very good sword?? How can you tell if a cold steel katana is good or not
- Can see this one is gong to cause a lot of controversy, price, country of origin, stuff like that might help you form an opinion on the particular sword
- Q:I've heard on some 1911 forums that the slides of Armscor guns are now extruded. What is extruded steel? How is it made? Are they strong (4140carbon steel was used in the process).
- Extruded steel is only the steel being run through a die when it is heated, it usually reduces the size of the grain of the steel itself, enhancing toughness. Realistically though, in a handgun, it doesn't matter if the frame is cast or forged, both types will hold up to any amount of abuse, unless you use it as a sledgehammer, and are splitting stones with it, then the forged frame would win. 4140 is more than adequate for a slide/frame. Hell, even mild steel would be adequate as long as you don't mind some dings and scratches, and again, don't use it as a sledgehammer...
- Q:How are steel coils inspected for camber?
- Steel coils are inspected for camber by using a straight edge or a camber gauge, which is placed on top of the coil to measure any deviation from straightness. The operator checks the distance between the straight edge and the coil at various points along its length to determine the amount of camber present.
- Q:What is the weight of a standard steel coil?
- The weight of a standard steel coil can vary, but on average, it ranges from 10 to 20 tons.
- Q:Maybe it is obvious. But i have thought alot about it.I thought steel at a cool temperature was unbreakable. I am not one for science or physics or engineering (i am a political science major). But i don't understand why the planes that struck the world trade center on 9-11 didn't just dent the side and fall,How did the place break the steel? Was it the velocity? Is steel easily broken?I realized that i wasn't taught how the planes broke the steel, and that no one ever asked. I searched the web and i couldn't find the answer or even anyone who had asked the question before.(i don't care about conspiracy theories, i just want scientific facts)
- I saw a one-hour program about this on PBS a couple of years ago. The buildings were constructed with the concrete-clad steel supporting columns at the center of the buildings, with a relatively thin lattice of steel struts along the outer wall. When the planes hit, they sheered through the thin steel struts easily by sheer momentum, while, at the same time, the thin steel stripped off the wings. The bodies of the planes got as far as the supporting columns in the center of the buildings, but were stopped there. The heaviest, densest pieces, the engines, went completely through the buildings and popped out the other side. It's important to understand that even light materials can cut through metal, if the light material is going fast enough. I saw this first hand, when I was in the Navy and stationed on board ship. We had a helicopter crash on our flight deck during heavy weather. The blades were made of light, carbon-composite material, but they were going so fast that they cut through the aluminum deck. I still have photos of that damage.
- Q:i mean the properties include the elasticity, impact load and ductility. am doing assignment about the perfect material that should be possessed by spring and i found alloy steel is the perfect and am confused whether stainless steel is the same with alloy steel ?
