The difference between cold rolling aluminum plate and hot rolled aluminum plate


The classification of aluminum industry, aluminum plate, many according to different production process, the aluminum plate can be divided into cold rolling aluminum plate and hot rolled aluminum plate. Cold rolling aluminum plate and hot rolled aluminum plate difference is as follows:
1, the production process is different: cold rolling is casts Mr Machined into firm volume (8 mm thickness) after a cold rolling machining, and hot rolling is aluminum ingots (400-500 - mm thickness), heating, composed of hot rolling mill rolling at high temperature;
2, different raw material supply: supply is not the same, the difference in the billet heating hot rolled billet casting aluminum ingots - - - rolling rolls for cold rolling, cold rolling billet is rolling roll, cold rolling mill;
3, different performance: good hot rolled aluminum plate surface quality, mechanical properties and ductility at the same time can be strong, oxidation effect is good, at the same time processing aluminum wafer are generally aluminum processing, nature also is affected by the performance of aluminum plate;
4, use different: cold rolling aluminum plate used for mould, hot rolled aluminum plate is suitable for stamping for stretching.
