Q:I want to get a new knife but i cant decide if i wan a spyderco pacific salt or a cold steel ak47
Given okorder / but always shop around and try Ebay...
Q:also what are the factors of location of these steel plants
I work for a pipe manufacturer in Birmingham, AL. We have multiple divisions including two specialized steel pipe divisions and a ductile iron pipe divisions. As far as the steel pipe divisions, they purchase skelp from suppliers. All of the steel that they purchase is of domestic manufacture, and is very expensive. As for the ductile iron division, we manufacture our own iron for the pipe. To get the iron that we need, we buy scrap in the form of cars, refrigerators, rejected pipe that we produce, etc. It is shredded in one part of the plant, and then melted and cast as a new product. This has become very problematic, scrap prices have skyrocketed in the US due to the large demand from countries such as China who gobble all of the material because they need great quantities of it. So, to answer your question, we get steel from recycling and then some raw iron ore. As to where we get the raw ore, I'm not 100% sure.
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 do steel coils contribute to structural integrity in buildings?
The role of steel coils in ensuring the structural integrity of buildings cannot be overstated. They play a vital role in multiple ways. To begin with, steel coils are extensively utilized in the construction industry to manufacture essential building components like beams, columns, and trusses. These components are responsible for providing support and stability to the overall structure. Due to their exceptional tensile strength and durability, steel coils guarantee that these components can withstand heavy loads and maintain their structural integrity over an extended period. This is particularly crucial in buildings with multiple floors or large open spaces, where the structural elements need to bear substantial weight without deforming or collapsing. Moreover, steel coils are also instrumental in reinforcing concrete structures. Reinforced concrete is a widely adopted construction technique, and steel coils, in the form of reinforcement bars or mesh, are embedded within the concrete to counteract tensile forces. While concrete excels at withstanding compressive forces, it is weak in tension. By incorporating steel coils, the composite material gains the ability to resist both compression and tension, thereby enhancing its structural integrity. This reinforcement technique is particularly vital in high-rise buildings or structures subject to seismic activity, where the risk of structural failure due to bending or cracking is heightened. Another significant contribution of steel coils to structural integrity lies in their corrosion resistance properties. Steel coils are often coated with protective layers, such as zinc through galvanization or paint, to prevent corrosion caused by moisture, chemicals, or environmental factors. Corrosion weakens the structural integrity of steel, leading to degradation and potential failure. By utilizing corrosion-resistant steel coils, the lifespan of the building is prolonged, and the risk of structural damage is significantly diminished. Furthermore, steel coils offer tremendous versatility in design and construction. Their flexibility and malleability allow for the creation of complex and intricate building structures, enabling architects and engineers to push the boundaries of design while maintaining structural integrity. Steel coils can be shaped, bent, and welded into various forms, making them an ideal material for constructing innovative and aesthetically pleasing buildings. In conclusion, steel coils are indispensable in ensuring the structural integrity of buildings. Their strength, stability, durability, corrosion resistance, and design versatility make them an essential material in modern construction, guaranteeing the safety and longevity of buildings for years to come.
Q:What is the role of steel coils in the production of storage tanks?
Steel coils play a crucial role in the production of storage tanks as they are used to construct the cylindrical body of the tank. These coils are cut and shaped into the desired dimensions and then welded together to create a strong and durable structure. The high strength and corrosion resistance properties of steel make it an ideal material for storage tanks, ensuring the safety and longevity of the tanks in various industries such as oil and gas, chemical, and water storage.
Q:What are the different types of steel coil surface treatments for corrosion resistance?
To enhance corrosion resistance, different methods are utilized for treating the surface of steel coils. These treatments create a protective layer that prolongs the lifespan of the steel and prevents corrosion. Some commonly used treatments for corrosion resistance include: 1. Galvanizing: Widely recognized as an effective method, galvanizing involves applying a layer of zinc to the steel coil's surface. The zinc acts as a sacrificial anode, corroding before the steel, thus safeguarding it against rust and corrosion. 2. Chromate conversion coating: This treatment entails applying a chromate-based solution to the steel coil's surface. The chromate forms a thin film that serves as a protective barrier against corrosion. Moreover, it improves the adherence of paint or other coatings that may be applied subsequently. 3. Phosphating: Phosphating is a process where a phosphate coating is added to the steel coil. This coating establishes excellent corrosion resistance by chemically bonding with the steel surface. It also enhances the adherence of subsequent coatings or paints. 4. Organic coatings: These coatings comprise paint or epoxy and are applied to the steel coil to create a barrier between the steel and its surroundings. They offer corrosion resistance and enhance aesthetic appeal. The selection of organic coating depends on the specific application and the desired level of corrosion protection. 5. Zinc-rich paint: Similar to galvanizing, zinc-rich paint contains a high concentration of zinc particles. When applied to the steel coil, these particles provide sacrificial protection, preventing corrosion. This coating is commonly employed in harsh environments or for steel coils exposed to frequent moisture or saltwater. It is important to consider various factors such as the application, environment, budget, and required level of corrosion resistance when choosing a surface treatment. Consulting with a steel coil manufacturer or corrosion specialist is advisable to determine the most suitable treatment for a specific situation.
Q:How are steel coils used in the manufacturing of railway wagons?
Steel coils are used in the manufacturing of railway wagons as they serve as a raw material for various components such as the wagon body, chassis, and structural parts. These coils are processed, cut, and shaped to form the required parts, ensuring the wagon's strength, durability, and load-bearing capacity. The steel coils are transformed into sheets, plates, or beams, which are then welded, bolted, or riveted together to construct the wagon's framework and body. Overall, steel coils play a vital role in providing the necessary strength and structural integrity to railway wagons.
Q:How are steel coils tested for dimensional accuracy?
Steel coils are tested for dimensional accuracy using various methods such as measuring the width, thickness, and length of the coils. This can be done through manual measurement using measuring tapes or calipers, or with the help of advanced technologies like laser-based sensors or non-contact measurement systems.
Q:How are steel coils processed for painting or coating?
Steel coils are typically processed for painting or coating through a series of steps. First, the coils are cleaned to remove any dirt, oil, or rust. This is usually done through a chemical cleaning process or by using mechanical methods such as shot blasting. Next, the coils are pre-treated to enhance adhesion and corrosion resistance. This can involve applying a conversion coating or a primer. Finally, the coils are painted or coated using a variety of methods such as roll coating, spray coating, or electrostatic coating. The specific process depends on the desired finish and application requirements.
Q:What are the dimensions of steel coils used in the construction equipment industry?
The dimensions of steel coils used in the construction equipment industry can vary, but they are typically around 48 to 72 inches in width and have an outer diameter of 60 to 80 inches. The weight of these coils can range from 5,000 to 30,000 pounds.
