摘要
本文采用价值分析的方法,对火焰切割的功能与成本的合理结合问题进行了研究.通过对乙炔、丙烯,丙烷和液化石油气四种燃气的功能与成本分析,及切割性能试验,说明了采用氧—丙烷切割是在保证功能前提下。
In the paper,it has been discussed to combine the function with cost in gas flame cutting rationally.Through analyzing the function of the four gases:acenty- lene,propylene,propane and liquid petrolium gas,the cost and experiment of gas flame cutting.It is proved that oxy—propane cutting is the best plan in cutting with the proper function and reducing the process cost.
