These coils are then cooled and coiled into large rolls, ready for use in various industries such as automotive, construction, and manufacturing.
- Q: What other metal is used to make rings? My girlfriend is allergic to stainless steel, but she wears a silver/grayish color ring, but I'm not sure what metal it is. Any ideas? Thanks!
- silver, white gold, and platinum match the color of stainless steel the best. they last long, too ;)
- 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: What are the different methods of coil recoiling for narrow strip widths?
- There are several different methods of coil recoiling for narrow strip widths. One method is known as slitting and recoiling, which involves cutting the wide coil into narrower strips and then rewinding them onto a smaller coil. This is typically done using a slitting machine, which can make precise cuts to create the desired strip widths. Another method is known as edge trimming and recoiling. In this process, the edges of the wide coil are trimmed to create narrower strips, and then the remaining material is rewound onto a smaller coil. This method is often used when the edges of the coil are damaged or uneven and need to be removed before recoiling. Additionally, there is a method called tension recoiling. In this process, the wide coil is passed through a series of tensioning devices that help to create the desired strip widths. The tensioning devices can apply controlled pressure to the edges of the coil, allowing for precise recoiling of narrow strips. Furthermore, some companies use laser cutting technology for coil recoiling. This method involves using a laser beam to cut the wide coil into narrow strips, followed by rewinding onto a smaller coil. Laser cutting offers high precision and accuracy, making it an ideal option for narrow strip widths. Overall, the different methods of coil recoiling for narrow strip widths include slitting and recoiling, edge trimming and recoiling, tension recoiling, and laser cutting. Each method has its own advantages and is chosen based on the specific requirements and capabilities of the manufacturing process.
