Turnkey Solutions for the Modern-Day Primary Aluminium Casthouse: The Alba Line 5 Experience

摘要

Placing a turnkey order with one supplier for all the equipment that interfaces together, as on a casting line, is a very cost effective means of providing an efficient and flexible Casthouse Solution. Some of the benefits for the customer and the supplier include quick decision making, prompt resolving of interface issues, reduced delays, minimum cost deviations and better coordination on safety management systems. In 2003 ALBA, one of the world's leading aluminium producers, gave Solios Thermal the opportunity to demonstrate their ability to deliver when they awarded them the contract for turnkey supply of the casting lines for their Line 5 expansion. The scope of supply included 11 furnaces (two of them complete with electromagnetic stirrers), 3 Vertical Direct Chill (VDC) billet casters, 1 Continuous ingot caster and all interconnecting launders, associated degassing and filtration units. Various key stage decisions, layout considerations, and start up together with the benefits to the end user are discussed in this paper.
