辊锻是指用一对相向旋转的扇形模具使坯料产生塑性变形 ,从而获得所需锻件或锻坯的一种锻造工艺。它既可作为模锻前的制坯工序 ,为长轴类锻件提供锻造用毛坯 (称为制坯辊锻 ) ,亦可在辊锻机上实现主要的锻件成形过程或直接辊制出锻件(称为成形辊锻 )。辊锻工艺不仅可以获得较为
Roll forging refers to the use of a pair of fan-shaped mold rotating plastic deformation of the blank, so as to obtain the required forging or forging a forging process. It can be used as pre-forging billet process for the long axis forgings with forging blank (known as billet forging), but also in the roll forging machine forging process for the main forging or direct roll forging Forming roll forging). Roll forging process can not only get more
