- Q: were iron age weapons made of steel?
- Even in very early iron, a small amount of steel was produced by carburization, where the iron picks up carbon by laying in hot coals before quenching. This produces a thin layer of steel on the surface of the iron. By about 300 BC Damascus steel was being produced by the crucible method on the Indian subcontinent, and the Romans used steel from Noricum. In the first century BC the Chinese were melting cast iron and wrought iron together to make steel.
- Q: You have two steel wool pads,one is cut up into little pieces, and the other is whole, and they are both submerged in water. 1.Which steel wool pad will rust quicker?2.How much faster will that pad rust? (estimate+explain the estimate)6.How could you make the steel wool pad rust faster?Please dont tell me to do my homework because I tried, but I bought the wrong type of steel wool
- How to make it rust faster ? Adding oxygen to the water - bubbling air through it. Raising the temperature should make the reaction go faster, but I believe it also reduces the amount of dissolved gas. Adding salt, or an ionic compound like an acid, will accelerate electrochemical corrosion. That usually requires a less active metal, like copper, in contact with the steel, but variations in the composition of the steel may be sufficient to promote corrosion.
- Q: What is the thickness of a steel coil?
- The thickness of a steel coil can vary depending on the specific requirements and application. Typically, the thickness of a steel coil can range from a few millimeters to several centimeters.
- Q: How are steel coils used in the manufacturing of elevator components?
- Steel coils are used in the manufacturing of elevator components as they provide the raw material for producing various parts such as brackets, frames, and structural supports. These coils are processed through cutting, bending, and shaping techniques to create the necessary components that ensure the safe and efficient operation of elevators.
- 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: for instance Cr-Ni steeldoes this refer to plated steel or a uniform mixture
- stainless steel is an alloy normally iron with additions of C, Mn, Ni, Cr, and Nb - amounts added depend on properties required. Corrosion resistance is due to a very thin but dense layer of chromium oxide which forms at the surface and prevents further attack. Ordinary steel on the other hand becomes coated with a porous layer of iron oxide(rust) through which the atmosphere can pass and cause further corrosion.
- Q: How are steel coils coated for color and aesthetics?
- Steel coils are coated for color and aesthetics through a process called coil coating. This involves applying a layer of paint or coating onto the steel coil surfaces, which is then cured and bonded to create a uniform and durable finish. This coating process not only enhances the appearance of the steel coils but also provides protection against corrosion and other environmental factors, making them suitable for various applications in industries such as construction and automotive.
- Q: How do steel coils contribute to energy savings in buildings?
- Steel coils contribute to energy savings in buildings through their use in HVAC systems. These coils are commonly used in air conditioning units and heat pumps, where they help transfer heat between the indoor and outdoor environments. By efficiently absorbing and dissipating heat, steel coils enable HVAC systems to regulate the temperature inside the building more effectively, reducing energy consumption and costs. Additionally, the durability and long lifespan of steel coils minimize the need for frequent replacements, further contributing to energy savings in the long term.
- Q: What are the different methods of skin pass rolling for steel coils?
- Steel coils can undergo skin pass rolling using various methods, each possessing its own distinctive characteristics and advantages. Some commonly employed techniques include: 1. Dry Skin Pass: This method entails passing the steel coil through rolls without applying any lubricant or coolant. The absence of these substances aids in enhancing the steel's surface finish by minimizing thickness fluctuations and achieving a smoother texture. 2. Wet Skin Pass: This approach involves utilizing a water-based emulsion or coolant during the skin pass rolling procedure. The coolant serves to decrease friction and heat generated during rolling, resulting in improved surface quality and reduced risk of surface defects. 3. Electrolytic Skin Pass: This technique utilizes an electrolytic solution during skin pass rolling. The steel coil is submerged in the solution, and an electric current is applied to the coil, leading to controlled surface etching. This method is particularly effective in improving surface cleanliness and eliminating oxide scale. 4. Temper Mill Skin Pass: This method combines skin pass rolling with a tempering process. The steel coil undergoes a series of rolls, followed by a heating and cooling process to achieve the desired mechanical properties and surface finish. This method is commonly employed for high-strength and automotive-grade steel coils. 5. Tension Leveling: In this method, the steel coil is passed through a series of rolls while under high tension. This elongates the steel, reducing residual stresses and shape defects, thereby enhancing flatness and dimensional stability. It is important to note that the selection of a skin pass rolling method depends on factors such as the desired surface finish, required mechanical properties, and the type of steel being processed. Each method offers its own advantages and limitations, and manufacturers typically choose the most suitable approach based on their specific needs.
- Q: What are the different methods of pickling steel coils?
- There are several methods of pickling steel coils, including acid pickling, electrolytic pickling, and mechanical pickling. Acid pickling involves immersing the coils in a bath of diluted acid, such as sulfuric acid or hydrochloric acid, to remove surface oxides and impurities. Electrolytic pickling uses an electric current to remove the oxide layer from the steel coils, usually in a solution of sulfuric acid. Mechanical pickling involves scrubbing the coils with abrasive materials or using mechanical rollers to remove the scale and impurities. Each method has its own advantages and is chosen based on the specific requirements and conditions of the steel coils.
