摘要
讨论了汽油作为切割气的可行性。通过大量实验说明：在汽油中添加５％左右的ＴＪ－１添加剂气油的粗溜点基本保持不变，但汽油的沸程相应降低１０－２０℃；通过在汽油中加入千分之一至千分之五的ＴＪ－２助燃剂，气油的燃烧速度大幅度提高，火焰的峰线长度由２厘米左右增加到１２厘米左右。在不影响割具所有性能的基础上，采用适当的汽化方式，使汽油作为切割气的切割厚度可达１２厘米以上，切割速度快，切口小并且整齐，有较大的推广价值。
The feasibility of gasoline used for cutting gas is discussed in thispaper. Experiment shows that the initial boiling point of the gasoline added about 5% additive TJ 1 has hardly changed, but the boiling range of the gasoline becomes relatively narrow, and the corresponding boiling point decreases about 10 to 20(C.By adding about TJ2 comburant of 0.1 %～ 0.5% in gasoline, the combustion rate of the gasoline increases dramatically, the length of flame front with highpressure oxygen gas increases from 2 centimeters to 12 centimeters. Without any effect on performance of cutting tool, an appropriate way of vaporizing gasoline is employed, the cutting thickness will reach 12 centimeters or more. In addition, the cutting rate is fast, the notch is small, nonstaggered and smooth. Therefore, the technique will be valuable for popularization.
