自由锻造水压机砧块的寿命问题,我厂和各兄弟厂一样,多年来,一直没有得到很好的解决。采用普通结构钢制成的砧块,高温强度差,在大型灼热钢锭的烘烤后,经不起水压机的巨大压力,一般连续使用两至三天就因工作面变凹须刨削一层才能继续使用(合金工具钢砧块变凹后更难刨削,尽管寿命稍长一点,也很少采用),一副上、下砧经四至五次刨削便报废。这不但是一个很大的浪费,而且经常因砧块供不应求严重影响水压机生产。我厂一水
Free forging hydraulic anvil life expectancy, I plant and brothers plant, over the years, has not been well resolved. Anvil made of ordinary structural steel, high temperature strength is poor, after the large hot steel ingot bake, can not withstand the enormous pressure of the hydraulic press, the general continuous use of two to three days because of the face to be plowed planing layer Continued use (alloy tool steel becomes more difficult to shave the anvils, even though the life is slightly longer), a pair of upper and lower anvil after four to five planing will be scrapped. This is not only a big waste, but often due to the anvils in short supply seriously affect the hydraulic press production. I plant a water
