【摘要】 研究了添加ＣｒＯ３－Ａｌ、Ｆｅ２Ｏ３－Ａｌ＋ＭｇＯ及Ｔｉ－Ｃ的Ｃｒ２Ｏ３－Ａｌ系的燃烧特性。实验发现，添加ＣｒＯ３－Ａｌ、Ｆｅ２Ｏ３－Ａｌ＋ＭｇＯ时，自蔓燃反应易于引发；体系中混入Ｔｉ－Ｃ添加剂对反应引发不利，但在用纯Ｔｉ－Ｃ作引火剂情况下可以引发。随着ＣｒＯ３－Ａｌ添加量的增加，燃烧温度升高，但添加量大于２０％时，燃烧温度反而下降。燃烧温度随Ｆｅ２Ｏ３－Ａｌ＋ＭｇＯ添加量的增加而升高。Ｔｉ－Ｃ添加量的增大对燃烧温度影响不大。燃烧速度随以上添加剂量的增大而增大更多还原

【Abstract】 he combustion characters of Cr 2O 3 Al system, in which CrO 3 Al, Fe 2O 3 Al+MgO and Ti C are added, have been researched. The ignition of Cr 2O 3 Al system is easy to carry out when CrO 3 Al and Fe 2O 3 Al+MgO are added in. When Ti C additive is mixed in CrO 3 Al mixture, it has negative effect on the ignition of Cr 2O 3 Al system, but combustion becomes easy to be ignited when Ti C igniter is put on the surface of mixture. Combustion temperature will increases with the increasing of CrO 3 Al, but it decreases when the additive quantity of CrO 3 Al is more than 20 percent. Combustion temperature also increases with the increasing of Fe 2O 3 Al+MgO.The increasing of Ti C has a little effect on combustion temperature. Combustion velocity increases with the increase of these additives.更多还原
