随着造船工业的蓬勃发展,钢材的加工量也不断增长,这对钢材加工中不可缺少的氧切割工艺提出了改革的要求。在毛主席无产阶级革命路线的指引下,我们两厂的工人、干部和技术人员遵循毛主席关于“中国人民有志气,有能力,一定要在不远的将来,赶上和超过世界先进水平”的教导,进行了扩散型超音速割嘴及快速切割工艺的试验研究。从1972年2月起先后研究成功多种类型的割嘴:切割氧压力为16公斤/厘米~2的氧乙炔中压扩散型割嘴、两种不同结构的氧丙烷中压扩散型割嘴、切割氧压力为8公斤/厘米~2级的
With the vigorous development of the shipbuilding industry, the processing volume of steel is also increasing, which poses the reform requirements for the oxygen cutting technology indispensable in steel processing. Guided by Chairman Mao’s proletarian revolutionary line, the workers, cadres and technical personnel of our two factories followed Chairman Mao’s message on “the Chinese people are ambitious and capable and must catch up with and surpass advanced world standards in the near future.” Of the teachings, conducted a diffusion supersonic nozzle cutting and rapid cutting process of experimental research. From February 1972 onwards, it has successfully studied many types of cutting tips: the oxygen pressure of 16 kg / cm ~ 2 oxygen pressure acetylene diffusion type cutting nozzle, two different structures of propylene oxide medium pressure diffuser nozzle, Cutting oxygen pressure of 8 kg / cm ~ 2 level
