摘　　要：针对特殊环境的切割要求,提出并研究试验了一种采用烟火药作为能源的燃烧型切割弹。燃烧型切割弹中切割剂由高热剂、造渣剂、合金剂、造气剂等组成,其中高热剂对切割弹性能影响尤为重要。通过无机热力学分析和计算,确定了高热剂成分并分析了不同高热剂配系对切割性能的影响。高热剂选用CuO+Al系和Fe2O3+Al系的混合物,当CuO+Al系占高热剂质量分数在13.6%～22.8%之间时,切割弹切割40 mm×70 mm×10 mm的Q235钢板的喷射时间、打孔深度、口径和锥度效果最好。A type of cutting technology of combustion cutting ammunition is developed which can meet the incise requirements in especial environmental.The cutting medicament is made up of high fever agents, gas-making agents, alloy agent and slagging agents.The high fever agents is very important for capability of the combustion cutting ammunition effects. The high fever agents are ensured by inorganic thermodynamics and the cutting performance was analyzed by different combination of thermit. The thermit can select the mixtures of CuO-A1 and Fe2O3＋Al. CuO-Al is up to 13.6% to 22.8% in the thermit to cut steel of Q235 in 40 mm×70 mm×10 mm on the basis of the eject times of case primer, depth of the hole, diameter of the hole and the taper.
