SpringerManufacturing of ultra-large plate forgings by unfolding and flattening &#;&#;Ultra-large plate forgings are foundation of heavy machinery, but many parts of the type cannot be made by conventional technologies due to the characters of extreme manufacturing in terms of size and quality requirements. This paper introduced a systematically method called cylinder unfolding method (CUM) for producing large plate

WikipediaForging - WikipediaForging is one of the oldest known metalworking processes. Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could be produced and
