| Abstract Scope |
A novel hybrid casting technology is presented that integrates continuous twin-belt solidification with metal delivery at the convergence zone to rapidly solidify a thin aluminum strip. This eliminates the conventional hot-rolling stage required by existing belt and block casting routes. By coupling the belts' uninterrupted, joint-free mold surface directly with full solidification within the mold, the process achieves a homogenous microstructure. The very high solidification rate eliminates inverse segregation which makes the technology attractive to surface-critical end-products. Preliminary trials at a width of 1 meter indicate the viability for end-product applications with demanding mechanical and forming requirements. The technology can accommodate higher scrap content than competing technologies. CASTechnology® will use the least amount of energy, offer the lowest CO2 emissions, and occupy the smallest plant footprint of any process for producing hot rolled aluminum strip. |
