151—24级动叶片是我国目前汽轮机制造中最大的一级叶片。其总长约819毫米(包括叶根和定位);宽约150毫米;净重11.2公斤。在制造第一台151汽轮机时,该叶片是用方钢加工而成。方钢尺寸为175×115×835毫米;重量135公斤;材料利用率极低,只有9.2%。通过第一台试制,一致认为有必要采用模锻叶片,以减少加工工时,节约材料。在厂革委会支持和车间革委会领导下,经过全厂十一个车间的协助,仅用七个月时间就将锻模和夹 151-24-stage moving blades are the largest turbine blades in China. The total length of about 819 mm (including the root and positioning of leaves); width of 150 mm; net weight of 11.2 kg. In the manufacture of the first 151 steam turbine, the blades were machined from square steel. Square steel dimensions of 175 × 115 × 835 mm; weight of 135 kg; material utilization is very low, only 9.2%. Through the first trial, it was agreed that it is necessary to use die forging blades to reduce the processing time and save materials. Under the leadership of Plant Revolutionary Committee and the Workshop Revolutionary Committee, with the assistance of eleven workshops of the whole plant, the die and clamps
