压铅杆(图1)是我厂锻造车间一个关键件。其主要困难是头部直径太大锻比不够,起重设备锻锤能力都受限制。但是,工人们以敢想敢干的共产主义风格终于克服了重重困难。因锤与起重设备能力都不足,只好选用3.1吨钢锭。但它的大头才有600毫米,所以就开坯后锻出头部(一锭取两个毛坯见圆2),这样不但解决了设备吊车问题,而且也保征了锻比。但由于锻件太高,再加上工具高560毫米、头部厚度250毫米,总高就有810毫米。而下砧到 Lead pressure rod (Figure 1) is a key plant forging workshop. The main difficulty is that the head diameter is too large forging ratio is not enough for lifting equipment forging hammer capacity are limited. However, the workers finally overcome the difficulties with a daring communist style. Due to hammer and lifting equipment are not enough capacity, had to use 3.1 tons of ingot. However, its bulk is only 600 mm, so it is necessary to forge the head after the billet is prepared (one round and two rough billet can be seen at round 2). This not only solves the equipment crane problem, but also insures the forging ratio. However, due to forgings is too high, together with tool height 560 mm, 250 mm head thickness, the total height of 810 mm. And under the anvil to
