在电石生产赶不上生产大跃进的形势下,我厂技术人员与工人先后创造了许多节约和代用电石的切割方法。最近根据苏联先进经验,试制成功联动式乙炔节气阀,并根据同样原理,在结构上作了重大改进,又创造成功按钮式乙炔节气阀。经多次试验证明,当钢板在一般条件下进行切割时,能节约电石40～50％。如果进一步提高操作技术,电石节约率还有可能提高。这种节约乙炔的办法,就是在切割器上装上一个乙炔节气阀(以下简称节气阀)。它的切割过程与普通方法一样,用中性火焰在切割起点将钢板加热到燃点,但
In the calcium carbide production can not keep up the production of the Great Leap Forward situation, our factory technicians and workers have created many savings and substitution of calcium carbide cutting method. Recently, according to the advanced experience of the Soviet Union, trial-production linkage acetylene throttle valve, and according to the same principle, made significant improvements in the structure, but also to create a successful button acetylene throttle. After several tests proved that when the steel under normal conditions for cutting, can save 40-50% of calcium carbide. If you further improve the operation of technology, carbide saving rate is also likely to increase. This method of saving acetylene, is installed on the cutter acetylene throttle (hereinafter referred to as the throttle). Its cutting process is the same as the normal method, with a neutral flame in the starting point of the cutting plate heated to the ignition point, but
