- Q: What are the different methods of tension leveling for steel coils?
- There are several methods of tension leveling for steel coils, each with its own advantages and applications. 1. Roller leveling: This method involves passing the steel coil through a series of rollers under high tension. The rollers are strategically positioned to apply pressure on the coil, effectively stretching and elongating it. Roller leveling is commonly used for thinner gauge coils and is effective in removing coil set, crossbow, and edge wave defects. 2. Stretch leveling: In this method, the steel coil is subjected to a combination of tension and elongation. The coil is gripped by clamps at both ends and then stretched using hydraulic or mechanical devices. This process helps to remove residual stresses, flatten the coil, and improve shape control. Stretch leveling is particularly suitable for thicker gauge coils and can effectively eliminate wavy edges and center buckle. 3. Temper rolling: This method involves passing the steel coil through a series of temper rolls, which apply pressure on the surface of the coil. Temper rolling is primarily used to improve the surface finish of the steel and enhance its mechanical properties. It can also help to reduce coil set and improve flatness. 4. Skin pass rolling: In this method, the steel coil is passed through a series of rolls that apply a light pressure on the surface. Skin pass rolling is typically performed after the primary leveling process to further improve surface finish, enhance flatness, and reduce surface defects such as scratches or marks. 5. Stretcher leveling: This method involves clamping the steel coil at both ends and then applying tension to stretch it. The stretched coil is then held in this position for a period of time to allow for stress relief and shape correction. Stretcher leveling is commonly used for thicker gauge coils and can effectively remove coil set, crossbow, and center buckle. Each of these tension leveling methods offers unique advantages and is suitable for different types of steel coils and specific requirements. The choice of method depends on factors such as coil thickness, desired flatness, surface finish, and the specific defects that need to be corrected.
- Q: looking to buy a sashimi knife. what is the difference between white steel (1and2) and blue steel (1and2) in terms on characteristics. what gets sharper? what holds edge longer? basically any info on the pros and cons of each steel would be SO GREATLY APPRECIATED! thanks in advance to all who answer. i'm leaning towards white-2 steel for my first sashimi knife, started training on the sushi bar and need a new tool!

- Q: How are steel coils uncoiled?
- Steel coils are uncoiled using a mechanical process called decoiling, where the coil is placed on a mandrel and then unwound using a motor-driven system. The coil is pulled through a set of straightening rolls to ensure it is properly aligned and then fed into the production line for further processing or fabrication.
- Q: How are steel coils heat treated?
- Annealing is the method used to heat treat steel coils, resulting in improved mechanical properties and overall performance. To achieve this, the coils are heated to a specific temperature and slowly cooled down. This process relieves internal stresses within the steel and enhances its performance. To begin the heating process, the steel coils are raised to a critical temperature, typically between 800°C and 900°C, depending on the desired outcome. They are then maintained at this temperature for a specific period of time, allowing for the transformation of the steel's microstructure. Once the desired time has passed, the heated coils are carefully cooled down in a controlled manner. This gradual cooling process is crucial as it allows for a uniform and refined microstructure. It also helps prevent the formation of internal stresses that could weaken the steel. The annealing process can be conducted in various atmospheres, such as air, nitrogen, or hydrogen. The choice of atmosphere depends on the specific requirements and properties desired for the steel coils. For example, annealing in a protective atmosphere like nitrogen or hydrogen can prevent oxidation or decarburization of the steel surface. In conclusion, annealing is a crucial step in heat treating steel coils, resulting in improved mechanical properties, enhanced formability, and the desired characteristics for industrial applications.
- Q: full discription about hydrolics used in steel melting shop with hyd valve is use in thair circit too ?
- The correct spelling is hydraulics. I haven't heard the term steel melting shop you probably means a foundry or a steel mill The most obvious example i can think of is hydraulic-operated fork lifts. Hydraulic cylinders are used to lift the forks and to tilt them upwards or downwards. The valves are coneccted to levers next to the steering wheel. Hydraulic pressure is supplied by a hydraulic pump driven by a propane or diesel engine. In some forklift designs the wheels are also not connected directly to the engine, but driven by hydraulic motors. There are also a large variety of machines used in steel mills and metalworking companies to cut and shape metal parts. for example, press brakes, plate cutting shears, stamping presses, hole punch machines, drawing presses, etc. These types all operate in much the same basic way. They use a very large cylinder or group of cylinders to apply many tons of force to different kinds of metal working tools.
- Q: Why people prefer prefabricated buildings these days? Recently my friend has told me that he is going to owe a steel house so I was just thinking are these steel structures really durable and cheaper than concrete structures?
- It really depends upon the environment and the construction techniques used. Steel that is painted or coated will without maintenance eventually rust. I would expect this tendency to be exacerbated in a humid or shore environment. Heat may tend to cook a steel house and the structure does not add much thermal mass. Construction techniques tend to be fairly quick a part of the construction is essentially prefabricated. Work done in a factory will almost always be cheaper than work done in the field, all things being equal. Concrete can be fairly hi tech with lots of equipment or as seen in many parts of the world fairly low tech with lots of laborers. It is easy to change the characteristics of concrete depending upon how it is mixed, reinforced, and treated during the curing process. Because it is applied in a relatively fluid state it can flow around obstructions like bedrock and be formed up into interesting shapes. A concrete structure can be cooler as it provides thermal mass, and a heat sink. It's resulting rigidity may make it more subject to earthquakes than steel. We do really need to be smarter in constructing our homes to make them fit the land and not only the general environment but our particular micro environment.
- 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.

- do not run efficiently is the correct answer
- Q: Well actually I was just wondering why people were bashing on stainless so much for katanas. I heard that they don't hold their edge as well as carbon steel blades or Damascus steel. So what makes it so inferior to carbon or other types of steels?
- No real swords are made of stainless steel. Its is simply a poor material for swords. Only kitchen knives that are required to be easy to clean and corrosion resistant are made of stainless. Adding chromium and other trace elements adds nothing to the ability to cut well or hold an edge. It is not strong enough to withstand the forces involved, being too brittle and lacking in toughness. Those decorative swords are not really swords at all.... rather they are sword shaped objects.
