英国有色金属工艺中心已研究出conform连续挤压工艺来生产小直径的黄铜棒。相信该工艺总共能节省费用25％以上。传统的轧制或拉拔生产方法要求大量冷挤压加工或连续铸造坯料。黄铜冷态时很硬(特别是具有两相微观组织的那些合金),这就意味着需要多道次的轧制或拉拔,加上多次的中间退火和表面清洗作业。相反,只要一个道次通过conform挤压 British non-ferrous metal technology center has developed conform continuous extrusion process to produce small diameter brass rod. I believe the process can save a total cost of more than 25%. Traditional rolling or drawing production methods require a large number of cold extrusion or continuous casting billets. Brass is hard at cold (especially those with two-phase microstructure), which means that multiple passes of rolling or drawing are required, plus multiple intermediate annealing and surface cleaning operations. On the contrary, as long as a pass squeezed by the conformity
