[China Aluminum Network] The process of converting aluminum and aluminum alloys into single-sheet or rolled-up processed materials with rectangular cross-sections through smelting, ingot casting, pre-rolling preparation, flat roll rolling, heat treatment and finishing.
1. Aluminum and aluminum alloy sheet strips are supplied in hot-rolled condition, annealed condition, various grades of soft state and various heat treatment conditions.
2. Preparations before hot rolling include quality inspection of ingots, soaking, sawing, milling, cladding and heating.
3. The cooling rate during semi-continuous forging is very high, the dispersion process in the solid phase is difficult, and the ingot is liable to constitute chemical components and uneven arrangement, such as intragranular segregation, which reduces the plasticity.
4. When the surface of the ingot has the disadvantages of segregation, slagging, slagging, and cracking, the surface of the ingot should be milled (see non-ferrous alloy ingot milling), which is an important factor to ensure the quality of the finished product.
5. Hot-rolling: Hot rolling of aluminum alloy ingots is for cold-rolling blanks, or direct production of hot-rolled slabs.
6. Hot rolling technical guidelines include pass reduction, rolling temperature, rolling speed, and smooth cooling.
Nitrogen generation by Pressure Swing Adsorption (PSA) process is a technology used to separate nitrogen from a mixture of gases under pressure according to the special selective adsorption characteristics of the Carbon Molecular Sieves (CMS).
The Carbon Molecular Sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases. When the pressure is high enough, the oxygen molecules, which pass through the pores of CMS much faster than the nitrogen molecules, are adsorbed, while the coming out nitrogen molecules will be enriched in gas phase. The enriched oxygen air, adsorbed by the CMS, will be released by reducing the pressure. Then the CMS is regenerated and ready for another cycle of producing nitrogen enriched air.
