aluminium is not good in saltwater Steel rusts in fresh air let alone saltwater but its alot cheaper than other mass produced metals you can rivet or weld it cheaply unlike stainless steel or Aluminium We could make them of wood but thats been tried Glass fibre and plastic is good for small boats but to do and Aircraft carrier size ship i doubt it

Q:How are steel coils inspected for flatness using optical sensors?

The process of inspecting the flatness of steel coils involves the use of optical sensors, which are part of a system known as optical flatness measurement. This system employs high-resolution cameras to capture images of the steel surface as it passes through the inspection line. To begin, the steel coil is unwound and conveyed over a roller table. While in motion, the optical sensors are positioned above the coil to capture images at regular intervals. These sensors are typically a combination of laser line projectors and high-resolution cameras. The laser line projectors emit a thin, straight line of laser light across the width of the steel coil. This laser line serves as a reference plane for measuring the flatness of the steel surface. Subsequently, the high-resolution cameras capture images of the laser line interacting with the steel coil. The captured images are then subjected to analysis using advanced image processing algorithms. These algorithms examine the deformation of the laser line on the steel surface and calculate the deviations from the flat reference plane. These deviations indicate any irregularities or variations in the flatness of the steel coil. The optical sensors possess the capability to accurately detect even the most minute deviations in flatness, measuring them in micrometers or smaller units. This enables manufacturers to identify and correct any flatness issues in the steel coils before further processing or shipment. In addition to measuring flatness, optical sensors can also identify other surface defects such as waviness, scratches, or dents. By incorporating multiple cameras and laser line projectors from different angles, a comprehensive inspection of the steel coil's surface can be achieved. Overall, the utilization of optical sensors for inspecting steel coil flatness offers a swift, precise, and non-contact method. By identifying and addressing any flatness issues early in the production process, manufacturers can guarantee the delivery of top-quality steel products to their customers.

Q:I want to know the special characters or the advantages of the corton steel. In what cases it is recommended to use?Thank you.

*It is Corten steel.Grade A B. *Weathering steel, best-known under the trademark COR-TEN steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. United States Steel Corporation (USS) holds the registered trademark on the name COR-TEN. Although USS sold its discrete plate business to International Steel Group (now Arcelor-Mittal) in 2003, it still sells COR-TEN branded material in strip-mill plate and sheet forms. In some areas it may be known without the hyphen as Corten steel. The original COR-TEN received the standard designation A242 (COR-TEN A) from the ASTM International standards group. Newer ASTM grades are A588 (COR-TEN B) and A606 for thin sheet. All alloys are in common production and use. It is a weather-resistant steel which is used in containers and hot flue gas line. The American Corten A Steel has a composition of C, 0.12; Si, 0.5; Cu, 0.5; Cr, 0.8; P, 0.1 and Mn, 0.5%. Although the tensile strength is less than 494 MPa the yield is in the region of 371 MPa. The combination of copper and phosphorus also increases the resistance to atmospheric corrosion which is important when thinner plates are used. The original steel A suffers a decrease in yield strength and notch ductility in thickness over 25 mm, to overcome which Corten B was developed-C 0.14; P 0.04; Mn 1.1; Cr 0.5; Cu 0.4; V 0.1; Bol Al 0.02. *COR-TEN A applies to plates up to 12.5mm in thickness, COR-TEN B applies to plates up to 50mm in thickness. *It has been used in bridge and other large structural applications such as the New River Gorge Bridge, the newer span of the Newburgh-Beacon Bridge, and the creation of the Australian Centre for Contemporary Art (ACCA). It is very widely used in marine transportation, in the construction of shipping containers.

Q:I'm going to see Man Of Steel this weekend, and the reviews that I've been hearing aren't that good. I've been hearing that it's this depressing, dark, dramatic film with no humor, loud noises, and action on top of action (which is kind of what I expected from this movie). With that said, I was quite positive that this was what the fans wanted, a more serious Super Man interpretation. I'm ultimately going to judge the movie when I see it, but for now, I have 3 short questions for you:1) What did you think of Man Of Steel?2) Superman Returns got somewhat better reviews than Man Of Steel. Does it seem logical?3) There is a huge fan battle between Man Of Steel and Christopher Reeve's version of Super Man. Which one do you favor?

I loved the new interpretation in Man of Steel Superman Returns got very poor reviews in the beginning, and as the hatred has worn off and fans have been the only ones voting, the score has moved up. As fond as I am of Christopher Reeves, his version was a touch campy. I much prefer the serious treatment.

Q:How are steel coils manufactured?

Steel coils are manufactured through a series of processes that involve the transformation of raw materials into the final product. The manufacturing process begins with the extraction of iron ore, which is then smelted in a blast furnace to produce pig iron. The pig iron is further refined in a basic oxygen furnace to remove impurities and adjust the carbon content. Once the molten steel is obtained, it is continuously cast into large slabs or billets. These slabs are then rolled into thinner sheets or strips through a process called hot rolling. This involves passing the steel through a series of high-pressure rollers, which reduce the thickness and shape the material to the desired dimensions. During this process, the steel is also treated to improve its mechanical properties, such as strength and hardness. After hot rolling, the steel is pickled and cleaned to remove any scale or impurities on the surface. It is then cold rolled to further reduce the thickness and improve the surface finish. Cold rolling involves passing the steel through a set of rollers at room temperature, which increases its strength and dimensional accuracy. To form steel coils, the cold-rolled steel is typically wound tightly into a large coil shape. This is achieved by feeding the steel strip through a series of rollers that gradually wind it into a spiral. The coils are then typically annealed to relieve internal stresses and improve the material's formability. Finally, the steel coils are coated or treated, depending on their intended use. This can involve applying a protective coating, such as zinc or paint, to enhance corrosion resistance or providing a specific surface treatment for improved adhesion in subsequent processes. Overall, the manufacturing of steel coils is a complex process that involves several stages, including smelting, casting, hot rolling, cold rolling, coiling, and surface treatment. Each step contributes to the final product's quality and properties, ensuring that steel coils meet the required specifications for various 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.
