Q: How are steel coils used in the manufacturing of agricultural implements?
Steel coils are used in the manufacturing of agricultural implements by being shaped and formed into various components such as blades, tines, and frames. These components are then assembled or attached to the implements, such as plows, harrows, and cultivators, to enhance their durability, strength, and performance in agricultural activities.
Q: How are steel coils used in the production of metal partitions?
The production of metal partitions relies heavily on steel coils, which are a vital ingredient. These coils, typically made from top-notch steel, act as the primary material for manufacturing the partitions. To begin with, the steel coils undergo a process called slitting, where they are sliced into narrower strips of the desired width. This step allows manufacturers to tailor the size of the metal partitions according to specific project requirements. Following slitting, the steel strips are fed into a roll forming machine. This machine gradually transforms the strips into the desired profile for the metal partitions. The roll forming process involves passing the steel strips through a series of rollers, which progressively bend and shape the metal into the desired form and dimensions. Once the metal has been shaped as desired, it is then cut into appropriate lengths to create individual partitions. These partitions undergo further processing, such as welding or spot welding, to join different components and enhance their structural integrity. Steel coils are highly preferred for metal partition production due to their strength, durability, and versatility. The use of steel ensures that the partitions can withstand heavy loads, resist corrosion, and offer long-lasting performance. Moreover, steel coils provide a high degree of design flexibility, allowing for the creation of various partition styles, including solid panels, perforated screens, or mesh partitions. All in all, steel coils play a pivotal role in the production of metal partitions by providing the necessary raw material, strength, and customization options required for these adaptable architectural elements.
Q: i found a similar question asking what metals were in stainless steel but i don't know if they are the same.... they probably aren't.
steel is iron with a little bit of carbon mixed in. how much carbon determines the hardness of the steel. stainless steel is the same mostly, it has nickle and chromium added in to make it corrosion resistant.
Q: I am doing an assignment for my materials class, im not asking for the answer but just some help. I have the assignment finished and handed in but the teacher gave it back with one comment, he asked me to explain the grain growth in steel during hydraulic press bending. Im completely stuck, please help. Thanks.
when you press bend metal , its gets a little hotter at the point of the bend , its like bending a piece of metal back and fourth , the area of the bending gets hot .the distance between the atoms at that point expands thus, a small growth in the size of the metal
Q: what is the chemical process that makes steel harder when it is heated and cooled rapidly?what does the heating of it do to the atoms?what does the cooling of it do to the atoms?what makes tempered steel so strong compared to untempered steel?
You can't temper all steels. Generally the material must be a high-carbon or tool steel. Different alloys temper differently, and tempering is usually done to get a specific set of characteristics, so you must know what you are working with and use the right methods and temperature. If you do it wrong, the material may be hard but too brittle for the purpose or have other issues. It can be simple, such as heating to a dull red, carbonizing the surface (use an acetylene rich flame until it blackens the surface) and oil quenching. Do that to a piece of tool steel (like a screwdriver) and it will case (surface) harden it to the point you can't scratch it with a file. Tempering changes the way the molecular structure in the metal is linked and oriented.
Q: what do you think about producebility of low density steel? for example: can density of 1020 steel (or ony others) be decreased without any loss of other properties.
1. A method has been developed for magnetic phase analysis of Fermanal type alloys as-quenched and after aging. 2. The upper limit of alloying to ensure the optimal mechanical properties was determined more precisely for steel 9G28Yu9MVB. For rods aged at 550°C for 16 h the aluminum content should not exceed 9.2% and the carbon content 0.92%. 3. To ensure the optimal mechanical properties of the deformed metal it is necessary to obtain a fine-grained single-phase austenitic structure after quenching. The amount of hardening phase after quenching should not exceed 15–20% (saturation magnetization around 1600 G).
Q: I read that contrary to popular belief, today's folded steel swords are only made that way for tradition and cosmetics. In the past steel was very impure and therefore had to be folded in order to make a good sword. Today's steel manufacturing provides very pure steel and so folding the metal only makes it look nicer, but does nothing to improve the function of the blade.What do you think of this?

Q: How are steel coils unloaded from a truck or ship?
Steel coils are typically unloaded from a truck or ship using various equipment and techniques. The unloading process depends on the type and size of the coils, as well as the available resources and infrastructure at the unloading site. For unloading from a truck, a common method involves the use of a forklift or crane equipped with coil hooks. The coils are carefully lifted and positioned onto the ground or a designated storage area. Alternatively, some trucks may be equipped with specialized roll-off trailers that allow the coils to be rolled off the truck bed. When unloading from a ship, larger cranes are often used due to the size and weight of the coils. These cranes can be located either on the ship itself or on the dock. The coils are lifted from the ship's cargo hold using specialized lifting hooks or spreader bars and carefully lowered onto the dock or a waiting truck. In some cases, a coil transfer car or coil trailer may be utilized to move the coils from the ship's cargo hold to the unloading area. These devices are designed to transport and position the coils safely and efficiently. It is worth noting that safety measures are of utmost importance during the unloading process. Proper securing of the coils, equipment stability, and adherence to weight limits are crucial to prevent accidents or damage to the coils, the truck, or the ship. Overall, the unloading of steel coils from trucks or ships involves the use of specialized equipment such as cranes, forklifts, and coil hooks. These tools, along with proper planning and safety precautions, ensure the efficient and safe transfer of the coils to their designated storage or transportation areas.
Q: How are steel coils used in the production of storage systems?
Steel coils are used in the production of storage systems as they are transformed into various components such as beams, columns, and shelves. These components are then assembled to create the framework and structure of the storage systems, providing strength, stability, and durability to store items efficiently.
Q: So we all know a 1000lb steel ball will sink in water, but if you were to leave the center of the ball hollow and fill with air, if the steel ball was big enough in diameter it should float correct? What size would the steel ball need to be to float?
specific gravity of a steel is approximately 7.82 as compared to water. so, the hollow sphere(filled with air) is having volume more by 7.82 as compared to solid sphere, then the 1000 lb hollow steel ball float in the water (Why Do Ships Float? The Greek Mathematician and inventor Archimedes lived during the 3rd century BC. According to history he was in the bath one day when he discovered the principle of buoyancy which is the reason why huge Greek ships weighing thousands of pounds could float on water. He noticed that as he lowered himself into the bath, the water displaced by his body overflowed the sides and he realised that there was a relationship between his weight and the volume of water displaced. It is said that he ran naked into the street yelling heurEka which is where we get our word eureka! (I found it), Greek heurEka I have found, from heuriskein to find. The Buoyancy Principle: Archimedes continued to do more experiments and came up with a buoyancy principle, that a ship will float when the weight of the water it displaces equals the weight of the ship and anything will float if it is shaped to displace its own weight of water before it reaches the point where it will submerge. This is kind of a technical way of looking at it. A ship that is launched sinks into the sea until the weight of the water it displaces is equal to its own weight. As the ship is loaded, it sinks deeper, displacing more water, and so the magnitude of the buoyant force continuously matches the weight of the ship and its cargo.)
