在气体火焰金属加工中,一般都是用乙炔-氧焰来完成的。但是在电石缺乏的时候,在野外施工运用不便的地方,或者为了节省费用,有时可能用乙炔代用品来代替乙炔。就目前来说,所有乙炔代用品与氧混合燃烧的火焰温度都比乙炔-氧焰的温度低得多。如果能把某些乙炔代用品加以强化,即加入某些物质以提高其与氧混合燃烧的火焰温度,这在加工上将会是很有利的。同时也可以用这种方法改善某些矿区的天然燃气来解决金
In the gas flame metal processing, are generally used acetylene - oxygen flame to complete. However, in the absence of calcium carbide, in the field of construction inconvenience, or in order to save costs, acetylene substitutes may sometimes be used instead of acetylene. For the moment, all acetylene substitutes mix with oxygen to flame at temperatures much lower than acetylene-oxygen flame temperatures. It would be advantageous to process if certain acetylene substitutes could be fortified by adding certain materials to increase the flame temperature of their mixture with oxygen. This method can also be used to improve the natural gas in some mines to solve the gold
