The invention belongs to the technical field of metal material processing, and is an aluminum alloy slab clad continuous rolling device for additive manufacturing, including a first unwinding drum, a second unwinding drum, a rolling mill, an atomizer and a heater. The atomizer , the heater and the second unwinding drum are sequentially arranged above the first unwinding drum along the running direction, and guide rollers are arranged below the second unwinding drum, and the basic unwinding drum on the second unwinding drum After the slab is guided by the guide roller, it travels parallel to the base material on the first unwinding drum, and the rolling mill is located at the rear end of the running direction to roll and press the slab. Beneficial effects: the device utilizes the waste heat of the additive manufacturing aluminum alloy slab to realize the continuity of continuous aluminum cladding and rolling pressing on the upper and lower sides of the additive manufacturing aluminum alloy slab, without milling and acid and salty corrosion process, saving resources, Improving the processing efficiency of spray-rolled high-performance aluminum alloys.
Description
technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to an aluminum-clad continuous rolling device for additive manufacturing of aluminum alloy slabs. Background technique [0002] Additive manufacturing is a process in which the alloy liquid flow is atomized into fine droplets with high-pressure inert gas, flies and cooled under high-speed airflow, and is deposited into a blank before it is completely solidified. It has various advantages of rapid solidification technology such as the fine grain of the obtained material, uniform structure, and the ability to inhibit macro segregation. [0003] Due to the effect of rapid solidification, the obtained metal material has uniform composition, fine structure, no macro segregation, and low oxygen content. Compared with the traditional casting and forging process and powder metallurgy process, it has short process, simplified process and high deposition efficie...
