Aluminum coil, also named as aluminum roll, as outlined by the technique of creating procedure remedy, it can be divided into two kind, hot rolled aluminum coil and cold rolled aluminum coil. In regards to how to be certain the product sort we require, the difference of hot rolled aluminum coil and cold rolled aluminum coil must be get.
The difference in between the hot rolling aluminum coil and cold rolling aluminum coil:
Very first compared from aluminum coil production method, after the aluminum ingot melt, coupled with the metallic elements, heating 12-15 hours, once again flue in to the crystallization pool extract impurities, following cooling, peel the top layer of impurities. For heating oven heat preservation, the temperature needs to be controlled among 450-520 degrees, heat preservation for 12 to 15 hours, and then flue into the crystallization in the pool, right here is the distinct beginning of hot rolled and cold rolled aluminum coil, the hot rolling aluminum coil is stress rolling by mill above the heat preservation temperature, along with the cold rolling aluminum coil is pressure rolling by mill beneath heat preservation temperature.
Hot rolling and cold rolling have benefits and disadvantages every single in the exact same time. The cold rolled mostly treat the plate with can not be heat strengthen, the common specifications for surface is larger, and foil, and ultra-thin material also can only use cold rolling mill. Comparatively hot rolling gives cold rolled billet firstly, then a great deal of material need high corrosion resistance, fatigue resistance, high plasticity, etc, all these demands to be hot rolled.
