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。
According to the cutting requirements of special environment, a kind of combustion-type cutting bomb using pyrotechnics as energy source was proposed and researched and researched. Burning-type cutting bombs in the cutting agent by the pyrogen, slagging agent, alloy agent, gas agent, etc., of which the heat agent on the cutting elastic properties are particularly important. Through the analysis and calculation of inorganic thermodynamics, the composition of pyrogenic agents was determined and the influence of different pyrogenic agents on the cutting performance was analyzed. When the CuO + Al system accounts for 13.6% ~ 22.8% of the pyrogenic agent mass fraction, the cutters were used to cut the Q235 steel plate of 40 mm × 70 mm × 10 mm Jetting time, drilling depth, caliber and taper the best.
