Q:How are steel coils processed before they are used in manufacturing?

Steel coils undergo several processing steps before they are used in manufacturing. The first step is called pickling, where the coils are immersed in an acid bath to remove any surface impurities, such as rust or scale. This helps to improve the surface quality of the steel. After pickling, the coils go through a process called cold rolling. This involves passing the coils through a series of rollers to reduce their thickness and improve their dimensional accuracy. Cold rolling also enhances the mechanical properties of the steel, making it stronger and more durable. Next, the coils are annealed, which involves heating them to a specific temperature and then slowly cooling them. Annealing helps to relieve internal stresses in the steel and improves its formability and ductility. Following the annealing process, the coils may undergo additional surface treatments, such as galvanizing or coating. Galvanizing involves applying a layer of zinc to protect the steel from corrosion, while coating can involve applying various types of paint or polymer to enhance the steel's appearance or provide specific functionalities. Once the coils have been processed and treated, they are typically cut into smaller sheets or strips, depending on the manufacturing requirements. These sheets or strips can then be used in various manufacturing processes, such as stamping, forming, welding, or fabrication, to create a wide range of products, including automotive components, appliances, construction materials, and many others. In conclusion, steel coils undergo a series of processing steps, including pickling, cold rolling, annealing, and surface treatments, before they are ready to be used in manufacturing. These processes improve the quality, strength, and formability of the steel, allowing it to be transformed into a variety of products.

Q:How are steel coils inspected for surface defects?

Steel coils are inspected for surface defects using various techniques such as visual inspection, automated systems, and magnetic particle inspection. Visual inspection involves trained personnel examining the coils for any visible defects or irregularities. Automated systems utilize cameras and sensors to detect defects and anomalies on the coil surfaces. Magnetic particle inspection, on the other hand, involves magnetizing the coil and applying magnetic particles to reveal any surface defects through the formation of visible indications. These methods ensure that steel coils meet quality standards before further processing or shipment.

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)

1 nothing is unbreakable! 2 it is a question of velocity not that the plane was going very fast but! the difference between an explosion and a detonation is if the flame front is faster or slower than 1000 meter per second If you burn Hydrogen it burns fast, more than 1000 meter per second at that speed a plastic pen like those you use every day will puncture through a steel 2X4 used in modern building walls it is not thick steel but it is still steel! and the plastic piece is hardly deformed Those talking about aviation fuel... this is long, very long after the fact Guru

Q:Can steel coils be coated with anti-corrosive substances?

Yes, steel coils can be coated with anti-corrosive substances such as zinc, paint, or polymer coatings to protect them from rust and corrosion. These coatings act as a barrier between the steel surface and the surrounding environment, preventing contact with moisture and corrosive elements.

Q:I need steel toe shoes for a workplace, where can I get them?I live in Surrey,UK.

by on the internet or ppe clothing shops

Q:What is the role of steel coils in the manufacturing of storage racks?

Steel coils play a critical role in the manufacturing of storage racks as they provide the raw material for creating the structural components of the racks. These coils are typically transformed through processes like cutting, bending, and welding to form the various parts of the racks, such as the upright frames, beams, and shelves. The strength and durability of steel make it an ideal material for storage racks, ensuring they can withstand heavy loads and provide long-lasting support for storing items efficiently.

Q:could anybody tell me the the weight of a cubic metre of mild steel? and where to get this info from?

i thnk 7.85 the density of ms is 7.85 kg/cm2 and formula is density=mass/volume u have volume=1m3 7.85*1=mass so 7.85 kg

Q:Is boron steel or carbon steel a harder metal? Which one is more flexible?

Boron Steel

Q:What is the difference between cold rolled strip and cold rolled steel coil?

Single literal explanation, volume and band are different, appearance shape is not the same.

Q:I need to know how you rate the hardness of steel any ideas?

There's an instrument called a hardness tester. It has a stylus which is pressed into the surface of a sample of steel with a calibrated amount of force. The distance it penetrates tells you how hard the steel is. (This is sometimes called 'indentation hardness'). The most common scale is the Rockwell Scale. Actually it gets a little complicated because there are several scales, one for tungsten carbide (the hardest man-made material), one for aluminum and brass and soft steels, and one for hardened steels. Another scale for indentation hardness is the Brinell scale. It's a little less complicated, with one scale to measure the hardness of wood, plastic, etc. as well as steel.
