以前的实验已经表明由丙烷和空气或甲烷和空气形成的炉子气氛,不需预先在吸热性气体发生器中反应就可以进行气体渗碳。为了得到接近于平衡成分的炉子气氛,需用较低的气体流速,以便使气体
Previous experiments have shown that a furnace atmosphere formed from propane and air or methane and air can be gas carburized without prior reaction with a heat absorbing gas generator. In order to obtain a furnace atmosphere close to the equilibrium composition, a lower gas flow rate is required to allow the gas
