The Arvedi ESP process produces hot strip in a combined, continuous and uninterrupted casting and rolling process. In this type of plant, the energy consumption and the associated costs are up to 45 percent lower than those of conventional casting and rolling processes. This also means a significant reduction of CO2 emissions.
T. Ogata, in Comprehensive Nuclear Materials, .01.3.1.2.2 Continuous casting. Continuous casting is widely used in steel plants, and is also one of the candidates for MA-bearing metal fuel slugs.

Mar 01, 2021.Continuous casting direct rolling (CCDR) 6056 aluminum alloy was used in this study. The CCDR process is a composite fabrication process that comprises continuous casting and hot strip rolling [ 4 ]. CCDR is considered an emerging high-efficiency production technology in the metal industry because it saves energy and production costs.
This concerns metal flow in the first few passes of the slab through the roughing train of a hot strip mill where the strip thickness is in the order of mm and the work rolls maybe 1 m or more in diameter, leading to a roll diameter/strip thickness ratio in the order of 35. In the finishing train this ratio increases by at least an
