我们接受一些生产单位提出解决乙炔品的任务,对于干馏煤气强化问题作了进一步研究(54年曾初步估计用石灰,火碱强化可提高150～200℃)。在党的三结合教育方针指导下,以及天津市三船厂在设备方面的支援,现已取得一定成果。强化后的干馏煤气比纯干馏煤气的火焰温度提高约500℃,用在气割及有色金属和铸铁的焊接方面完全可以代替乙炔;焊接低碳铜薄板(1.5毫米以下)也可使用,但质量方面还待继续研究。
We accept the task of some production units to solve the problem of acetylene products. We have further studied the problem of carbonization of retort gas (54-year initial estimate of lime and caustic soda can be increased by 150-200 ℃). Under the guidance of the party’s three-pronged education policy and the equipment support of the three shipyards in Tianjin, some achievements have been achieved. The intensified retort gas is about 500 ° C higher than the flame temperature of pure retort gas, which can replace acetylene in gas cutting and welding of non-ferrous metals and cast iron. Welded low-carbon copper sheets (below 1.5 mm) can also be used, but the quality Still to be studied.
