[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. Plain Fiberglass Insect Screen
Ordinary fiberglass window screens, that is, ordinary fiberglass window screens, are usually classified according to different materials, qualities, specifications and uses. Here are some common classifications:
1. Classification by material: Ordinary fiberglass screens are mostly made of glass fiber yarn, and some are made of PVC fiber
2. Classification by quality: The quality of ordinary glass fiber screens varies greatly, mainly depending on the thickness, density, strength and encryption technology of the yarn.
3. Classification according to specifications: Ordinary glass fiber screens have different widths and lengths in different specifications, which can be selected according to the size of the window.
