现代锻压生产总的发展趋势是降低单位成品的金属消耗,以及靠高的质量指标来保证每个锻压另件尽可能长的使用寿命。机械制造厂最终产品的质量和成本在许多方面取决于热变形之前的金属加热。锻件机械性能、氧化和脱碳程度的规定值在许多情况下可以通过提高坯料加热速变的途径来 The general development trend of modern forging production is to reduce the metal consumption per unit finished product, and rely on high quality indicators to ensure that each forging parts as long as possible life. The quality and cost of the final product of a machinery manufacturer depends in many ways on the metal heating prior to thermal deformation. Forgings mechanical properties, oxidation and decarburization of the provisions of the value in many cases by increasing the speed of billet heating way
