Grain Oriented Electrical Silicon Steel Sheet

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: a concrete or steel building?also, what is the density of concrete and steel? is concrete heavier in steel for the same volume?: The denisty of reinforced concrete is taken to be 150 lbs/ft^3 The density of carbon structural steel is 490 lbs/ft^3

Q: How are steel coils processed for pickling or oiling?: Steel coils are processed for pickling or oiling through a series of steps. First, the coils are unwound and cleaned to remove any dirt or debris. Then, they are passed through an acid bath to remove any oxides or rust from the surface of the steel. After pickling, the coils are rinsed with water to neutralize the acid. Finally, the coils may undergo an oiling process where a thin layer of oil is applied to protect the steel from corrosion.

Q: Can solution annealing be done on carbon and low alloy steels. please give an explanatory answer.: No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.

Q: How are steel coils inspected for bendability using bend testers?: Steel coils are inspected for bendability using bend testers, which are specialized machines designed to measure the flexibility and bend resistance of the coils. The process involves several steps to ensure accurate and reliable results. Firstly, the steel coil is prepared by securing it firmly in place, usually using clamps or other mechanisms to prevent movement during testing. This ensures that the coil remains stable and allows for consistent and repeatable measurements. Next, the bend tester is set up according to the specified testing parameters. These parameters typically include the desired bend angle, the speed at which the bend is applied, and the number of cycles to be performed. The bend tester is equipped with a bending mechanism that exerts a controlled force on the coil, simulating the bending conditions it may undergo during its application or use. Once the bend tester is set up, the bending process begins. The machine applies a gradually increasing force to the steel coil until it reaches the desired bend angle. This force is carefully measured and monitored throughout the process to ensure accuracy. During the bending process, the machine records and displays important data, such as the applied force, the angle of bend, and any indications of cracking or other defects. This data is crucial for evaluating the bendability of the steel coil and determining whether it meets the required standards. After the desired bend angle is reached, the coil is released from the bending mechanism, and any residual stresses are allowed to relax. This relaxation period is important to observe any potential spring-back effect, where the coil partially returns to its original shape after bending. The amount of spring-back is also measured and recorded for further analysis. Finally, the inspection results are analyzed to determine the overall bendability of the steel coil. If the coil meets the specified bendability criteria, it can be considered acceptable for its intended application. However, if any cracks, fractures, or excessive spring-back are detected, further investigation and analysis may be required to identify the cause and determine appropriate corrective actions. In conclusion, bend testers play a vital role in inspecting steel coils for bendability. Through a controlled and systematic process, these machines accurately measure the flexibility and resistance to bending, helping to ensure the quality and reliability of steel coils used in various industries.

Q: I just got the game Red Steel for the Wii. I want to use the sword in multiplayer mode, but I can't find it. Is it only for single player?: Dude i hate to break it to you but its only single player, and if your talking about the first Red Steel, you can only use the sword in special moments in the game or showdowns i think that's what its called, but i play Red Steel 2, and its a better game, and you can use the sword anytime you want to, but again no online play, but it would be kinda nice to have it, just a thought!!! LoL Hope that helps....

Q: I am doing a experiment on mild steel soaked in sodium chlorideanyone can enlighten me about the effect of the sodium chloride in engineering term ?The mild steel specimen which I soaked in the sodium chloride has orange rust on it: The mild steel contains a lot of Iron. The NaCl solution quickly attacks the iron content and forms rust. Over time, the solution may also cause what is called 'Chloride Cracking' of the steel. Pitting corrosion of stainless steel due to chlorides would certainly produce a rust-colored product. Passivation can be used to maintain a good corrosion resistant surface of stainless steel process vessel. There are many commercial products for this purpose. In the pharmaceutical industry, this process is often called derouging, that is to remove the buildup of iron oxides on the stainless steel process surfaces

Q: We have to do a project for school on steel mines and i need 4 PROPERTIES OF A STEEL MINE PLEASE HELP!!! URGENT!!!: There's no such thing as a Steel mine - steel is made from various raw materials (and now recycled metals). These materials may be mined separately and then combined at a steel mill - but steel is made, not mined. Steel, depending on what final characteristics they're trying to develop (strength, hardness, finish , etc.) can be comprised of iron, carbon, manganese, phosphorus, sulfur, nickel, chromium, etc. in varying quantities.

Q: Where are the coils and the steel plates used? Where did the steel plate come from?: Steel plate is divided into many kinds of PU, low alloy, boiler plate, vessel plate, high strength plate, etc..

Q: What are the different methods of roll forming steel coils?: There exists a variety of techniques for roll forming steel coils, each possessing distinct features and uses. Some prevalent methods encompass: 1. Conventional Roll Forming: This technique, widely employed, involves gradually shaping a continuous steel strip into the desired profile by passing it through a series of rollers. It offers high precision and repeatability, making it ideal for manufacturing intricate shapes and profiles. 2. Pre-Punch and Cut: With this method, the steel strip is pre-punched with holes or slots before undergoing roll forming. This facilitates easier cutting and shaping during the forming process, enhancing efficiency and reducing waste in specific applications. 3. Post-Punch and Cut: Similar to pre-punching and cutting, this method adds holes or slots after the roll forming process. It provides greater flexibility in creating customized shapes and designs since the holes can be precisely placed as required. 4. Post-Forming: On certain occasions, the steel strip is initially roll formed into a basic shape or profile, which is then further manipulated or formed. This approach allows for additional customization and enables the creation of more intricate geometries. 5. Progressive Roll Forming: This technique involves continuously passing the steel strip through a series of rollers, with each roller gradually adding a distinct feature or forming a specific part of the final profile. Progressive roll forming is commonly utilized for lengthy, continuous profiles with repetitive shapes. 6. Incremental Roll Forming: In this method, the steel strip is incrementally shaped by means of small movements of the rollers. It provides greater flexibility in shaping complex profiles and proves particularly useful for producing prototypes or low-volume production runs. Ultimately, the selection of a roll forming method depends on the specific requirements of the application, such as the desired shape, complexity, precision, and production volume. Each method presents its own advantages and limitations, and manufacturers typically choose the most suitable technique based on these factors.
