【摘要】 对FM锻造新工艺(Free from Mannesmann Effect)进行了试验研究,求出了FM锻造法与普通锻造法对闭合空洞能力及锻造压力的相对关系,以及FM法的最佳砧宽比及压下率。为制定生产工艺提供了依据。按FM法锻造的模块成品合格率达到100％。更多还原

【Abstract】 The forging process, Free from Mannesmann Effect(FM) was tested. The relation between pore closing and forging pressure, the optimum ratio of anvil wide and the rate of reduction have been found. These results may be used as basis for working out the production technology. By means of FM process, 100% of the forged semis passed examination.更多还原
