Design and Test of Molten-Slag Thermite Unexploded Ordnance Destroyer
To conduct the research and application of the unexploded ordnance destroyer based on the molten-slag thermite combustion destruction technology,three kinds of unexploded ordnance destroyers with different length-diameter ratios and slag discharge accesses were designed.Three types of thermite were selected and the simulated destruction comparative experiments were performed.The influences of thermite formulations and destroyer structures on the reliable destruction of unexploded ordnance were clarified.The results show that the destruction effects of the three types of thermite after ignition in dif-ferent destroyers take on significant differences.The destruction performance of thermite destruction tech-nology depends on the coupling between the selection of thermite formulations and the structural design of destroyers.Al/CuO thermite exhibits the optimal destruction performance due to its faster combustion rate,higher reaction heat release and moderate slag formation rate.The destroyer with smaller length-di-ameter ratio and slag discharge grooves is more conducive to the flow and release of high-temperature slag,and the effectiveness of thermal penetration on steel plates,which is more suitable for the structural design of unexploded ordnance destroyers based on molten-slag thermite.
