一、锻工车间生产前的准备1.检查原材料是否存在端面毛刺及表面裂纹,如有应该铲除,以免锻造时将毛刺压入锻件内,形成折叠及裂纹,并扩展形成破裂。2.将所用锻锤及工具预热至150～200℃,防止在锻打过程中,锻件的表面急聚冷却,产生温度差,造成材料裂纹。二、锻坯加热及其注意事项1.加热工对所生产的原材料要做到心中有数,严禁不同材质的锻坯混合装炉。
First, the forging shop before the production of preparation 1. Check the raw material for the presence of surface burrs and surface cracks, if any should be eradicated, so as not to forge burrs pressed into forgings, the formation of folds and cracks, and the expansion of the formation of rupture. 2. Forging hammer and tools used to preheat 150 ~ 200 ℃, to prevent the process of forging, forging the surface of the emergency co-cooled, resulting in temperature differences, resulting in material cracking. Second, forging billet heating and precautions 1. Heating workers on the production of raw materials to be aware of, forging different materials mixed forging furnace.
