China Aluminum Shandong Branch successfully developed an electromagnetic continuous casting aluminum alloy layer gradient slab

At the beginning of the new year, Chalco's new aluminum alloy product R&D was a success story. Chinalco 2008 annual major scientific research project undertaken by Shandong Branch’s electrolytic aluminum plant—“Electromagnetic continuous casting aluminum alloy layer gradient slab technology industrialization research”, after more than 10 months of scientific research by Shandong Branch’s electrolytic aluminum plant technicians The efforts were finally successful, filling the gap in the industrialization of “Electromagnetic Continuous Casting Aluminum Alloy Gradient Slabs” in China, and also making this plant the second company in the world to have such technologies and achieving many Technological innovation.
The aluminum alloy multi-layered gradient cast blank is a high-tech product specially used for producing composite brazing aluminum foil. Currently, it is widely used in manufacturing fields such as automobile, aerospace, shipbuilding, electronics, and high-strength building materials. The market prospect is very broad. However, the traditional aluminum alloy composite technology is mostly made by mechanical equipment after repeated hot rolling and cold rolling of the aluminum alloy plate. The process flow is long, the efficiency is low, the combination of multiple layers interfaces is poor, and the reject rate is high. In March 2008, Shandong Branch’s electrolytic aluminum plant technicians undertook the “Electromagnetic Continuous Casting Aluminum Alloy Coated Gradient Billet Industrialization” research topic, through the aluminum alloy multi-layer gradient casting mold, electromagnetic braking system, multi-alloy The flow distribution system and other equipment are researched and designed. After many tests on the pilot line and constant optimization and improvement of technical solutions, a mature set of aluminum alloy layer gradient technology parameters and production technology are sought out. The casting meets certain requirements. "Electromagnetic Continuous Casting Aluminum Alloy Layered Gradient Slab".
Compared with traditional technology, "Electromagnetic Continuous Casting Aluminum Alloy Multi-layer Gradient Casting" realizes direct rolling and forming of composite cast billets, reduces the mechanical pressing and lamination process between slab ingots and slab ingots, and has higher product quality and energy consumption. Lower, the enhanced interface bonding after rolling, and the improved yield, effectively solved the technical difficulties such as the difficulty in guaranteeing the product layer thickness and accuracy in the traditional process.
Under the current market downturn, the successful development of "Electromagnetic Continuous Casting Aluminum Alloy Multilayered Gradient Cast Steel Billet" will undoubtedly add new economic growth highlights to Shandong Branch's loss control and profit increase, and promote the "optimization of product structure and improvement. The strategic adjustment of high-tech product structure has taken greater steps.
