  • Forging, Ring Rolling, Open-Die Forging, Hammer Forging-Kihlsteel.se

    View this video on the Forging process! Open-die forging can produce forgings from a few pounds up to more than 150 tons. Called open-die because the metal is not confined laterally by impression dies during forging, this process progressively works the starting stock into the desired shape, most commonly between flat-faced dies. In practice, open-die forging comprises many process variations, permitting an extremely broad range of shapes and sizes to be produced. In fact, when design criteria dictate optimum structural integrity for a huge metal component, the sheer size capability of open-die forging makes it the clear process choice over non-forging alternatives. At the high end of the size range, open-die forgings are limited only by the size of the starting stock, namely, the largest ...

Structural engineering is a specialized branch of civil engineering that entails analyzing and designing structures -- things like buildings, bridges and even concert stages. Engineering is a big discipline that involves a systematic approach to designing solutions to problems experienced in the real world. There are many different fields of engineering, like mechanical engineering, electrical engineering, civil engineering, chemical engineering and systems engineering. And within these categories there are various subcategories-- and structural engineering is a subcategory of civil engineering. Transcript Ever wonder how tall buildings can withstand windy days, or why bridges don't collapse when large trucks drive over them? The answer is structural engineering. Structural engineers use physics and math to design and analyze the sturdiness of structures, things like bridges, buildings, concert stages, and even roller coasters. Don't get me wrong. Designing any one of these things can involve multiple types of engineering, but it's structural engineering that's responsible for making sure that that structure won't collapse or fall over. You see, a structure must be able to handle the forces or loads that it's likely to experience. Take a skyscraper, for example. It not only has to support itself, but also all the people and furniture inside the building, and then external factors, like wind, snow, or an earthquake. The materials and geometry that make up a structure influence how it may respond to those forces. Different materials have different properties, like strength, weight, and flammability, that can influence a structure's sturdiness. For example, steel is generally stronger, and weighs more than wood, and different geometric shapes work better for different purposes. For example, a square or rectangular base can typically hold more weight than a triangular base. Structural engineers perform calculations to determine the best materials and shapes to use in order to build a study structure. The next time you find yourself at the top of a roller coaster, you can thank structural engineers for doing their part to make sure it's nice and sturdy.

An animation illustrating a complete cycle of aluminium extrusion production, including: die heating and transfer, billet heating, sawing, transfer to press, extrusion, cooling, sawing, stretching, stacking and ageing. Before extrusion begins, the die is also heated in a furnace. The die is a steel disk containing one or more cavities through which the aluminium is extruded. The die assembly is lowered into a holder and transferred into position within the press. The aluminium billets are heated in order to make them soft and then sawn to the required length. Before entering the press, the rear face is sprayed with a release agent to prevent it from sticking to the ram. Note that the billets are often heated so that the front end is hotter than the rear (taper heating). This is because as the billet progressively deforms in the press, it also heats up due to friction and deformation. Once inside the press, the billet is initially compressed and expands outwards to fill the container. Any trapped air is released by withdrawing the container/billet from the die face. The main extrusion cycle begins and as the profile emerges, it is cooled using air or water sprays in order to develop its metallurgical properties. At the end of extrusion, there is still a small length of billet remaining. This 'butt end' is sheared off in order to present a flat face for the subsequent billet to join onto. The extrusion is sawn off just past the cooling zone and then transferred to the stretcher. A small stretch is applied in order to remove any distortions and straighten the profile. This is then sawn to the final length. Finally, the profiles are stacked and may then go on for further processing, such as painting, anodizing or ageing, in order to produce the required surface finish, mechanical properties and corrosion resistance.

Mechanical coupling of the multiple structural elements of the large-conductance mechanosensitive channel during expansion. Jie Li et al (2015), Proceedings of the National Academy of Sciences http://dx.doi.org/10.1073/pnas.1503202112 The prokaryotic mechanosensitive channel of large conductance (MscL) is a pressure-relief valve protecting the cell from lysing during acute osmotic downshock. When the membrane is stretched, MscL responds to the increase of membrane tension and opens a nonselective pore to about 30 Å wide, exhibiting a large unitary conductance of ∼3 nS. A fundamental step toward understanding the gating mechanism of MscL is to decipher the molecular details of the conformational changes accompanying channel opening. By applying fusion-protein strategy and controlling detergent composition, we have solved the structures of an archaeal MscL homolog from Methanosarcina acetivorans trapped in the closed and expanded intermediate states. The comparative analysis of these two new structures reveals significant conformational rearrangements in the different domains of MscL. The large changes observed in the tilt angles of the two transmembrane helices (TM1 and TM2) fit well with the helix-pivoting model derived from the earlier geometric analyses based on the previous structures. Meanwhile, the periplasmic loop region transforms from a folded structure, containing an ω-shaped loop and a short β-hairpin, to an extended and partly disordered conformation during channel expansion. Moreover, a significant rotating and sliding of the N-terminal helix (N-helix) is coupled to the tilting movements of TM1 and TM2. The dynamic relationships between the N-helix and TM1/TM2 suggest that the N-helix serves as a membrane-anchored stopper that limits the tilts of TM1 and TM2 in the gating process. These results provide direct mechanistic insights into the highly coordinated movement of the different domains of the MscL channel when it expands.

Hypnotic Video Inside ¦¦ Tube Manufacturing ¦¦ Oil pipe ¦¦ Huge pipes The pipe - a long hollow, usually roundish object, article of manufacture on the basis of the hollow profile of constant section for wires liquids, fluids, gas, steam and so on. Pipes are produced by industrial methods, and alloys of metals, organic materials (plastics, resins), concrete, ceramics, glass, wood, and combinations thereof. In commercial scale pipe is used for transporting various media, insulation, reinforcement, or groups of electrical wires. Metal pipe is widely used in construction as a structural element (eg, metal) or mechanical (eg shaft - item for the transmission of rotation).

Describes the results." NEW VERSION with improved video & sound: https://www.youtube.com/watch?v=xXOtdTa2ypU Public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Carbon_steel#Heat_treatment The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance. Note that the electrical and thermal conductivity are slightly altered. As with most strengthening techniques for steel, Young's modulus is unaffected. Steel has a higher solid solubility for carbon in the austenite phase; therefore all heat treatments, except spheroidizing and process annealing, start by heating to an austenitic phase. The rate at which the steel is cooled through the eutectoid reaction affects the rate at which carbon diffuses out of austenite. Generally speaking, cooling swiftly will give a finer pearlite (until the martensite critical temperature is reached) and cooling slowly will give a coarser pearlite. Cooling a hypoeutectoid (less than 0.77 wt% C) steel results in a pearlitic structure with α-ferrite at the grain boundaries. If it is hypereutectoid (more than 0.77 wt% C) steel then the structure is full pearlite with small grains of cementite scattered throughout. The relative amounts of constituents are found using the lever rule. Here is a list of the types of heat treatments possible: - Spheroidizing: Spheroidite forms when carbon steel is heated to approximately 700 °C for over 30 hours. Spheroidite can form at lower temperatures but the time needed drastically increases, as this is a diffusion-controlled process. The result is a structure of rods or spheres of cementite within primary structure (ferrite or pearlite, depending on which side of the eutectoid you are on). The purpose is to soften higher carbon steels and allow more formability. This is the softest and most ductile form of steel. The image to the right shows where spheroidizing usually occurs. Full annealing: Carbon steel is heated to approximately 40 °C above Ac3 or Ac1 for 1 hour; this assures all the ferrite transforms into austenite (although cementite might still exist if the carbon content is greater than the eutectoid). The steel must then be cooled slowly, in the realm of 38°C (68.4°F) per hour. Usually it is just furnace cooled, where the furnace is turned off with the steel still inside. This results in a coarse pearlitic structure, which means the "bands" of pearlite are thick. Fully annealed steel is soft and ductile, with no internal stresses, which is often necessary for cost-effective forming. Only spheroidized steel is softer and more ductile... Normalizing: Carbon steel is heated to approximately 55 °C above Ac3 or Acm for 1 hour; this assures the steel completely transforms to austenite. The steel is then air-cooled, which is a cooling rate of approximately 38 °C (68 °F) per minute. This results in a fine pearlitic structure, and a more-uniform structure. Normalized steel has a higher strength than annealed steel; it has a relatively high strength and ductility. Quenching: Carbon steel with at least 0.4 wt% C is heated to normalizing temperatures and then rapidly cooled (quenched) in water, brine, or oil to the critical temperature. The critical temperature is dependent on the carbon content, but as a general rule is lower as the carbon content increases. This results in a martensitic structure; a form of steel that possesses a super-saturated carbon content in a deformed body-centered cubic (BCC) crystalline structure, properly termed body-centered tetragonal (BCT), with much internal stress. Thus quenched steel is extremely hard but brittle, usually too brittle for practical purposes. These internal stresses cause stress cracks on the surface. Quenched steel is approximately three to four (with more carbon) fold harder than normalized steel... Quench and tempering: This is the most common heat treatment encountered, because the final properties can be precisely determined by the temperature and time of the tempering. Tempering involves reheating quenched steel to a temperature below the eutectoid temperature then cooling. The elevated temperature allows very small amounts of spheroidite to form, which restores ductility, but reduces hardness. Actual temperatures and times are carefully chosen for each composition...
