Abstract

The invention relates to a method for producing a high-performance aluminum alloy plate strip through sheet billet continuous roll casting. The method comprises the following steps that firstly aluminum alloy melt is refined, and double-roller type sheet billet continuous roll casting is conducted on the melt by adopting a water-cooled casting roller with a nano-graphite coating on the surface forlubrication, so that a continuous rolled-cast sheet billet is obtained; and heat leveling, heating and homogenizing treatment, heat preservation and uncoiling for hot finish rolling are conducted. According to the method, procedures of semi-continuous casting, surface milling, homogenization heat treatment, hot rough rolling, intermediate annealing and the like of a traditional ingot casting hotrolling cogging method are omitted, the yield of the aluminum alloy plate strip is obviously improved by 20% or above, the production cycle is shortened from the original 20 days to about a 0.5 day, and the production efficiency is remarkably improved; and the production cost is reduced by 30% or above while the production process continuity is improved, and emission of pollutants of carbon / sulphide and the like are reduced by 50% or above, and large economic benefits and social benefits are generated.

Description

technical field [0001] The invention relates to a method for producing high-performance aluminum alloy plates and strips by continuous casting and rolling of thin slabs, and belongs to the technical field of material metallurgy. Background technique [0002] In recent decades, the metal processing industry at home and abroad has been developing new technologies around saving energy, reducing emissions, reducing production costs, improving production efficiency and yield, and improving product quality, so as to achieve long-term and continuous energy saving and emission reduction, and improve quality. the goal of. At present, aluminum alloy slabs are mainly prepared by semi-continuous casting method and obtained by rolling large slabs. The thickness of the ingot is more than 600mm and the length is about 6-8m. After milling and other processes, the finished product rate is less than 70%. The high energy consumption of heat treatment and the discharge of pollutants are huge o...
