Through research of stiletto and analysis of cutting process of manual thermite cutting technology, mechanism and chemical compositions of cutting ammunition is expounded. This type of cutting ammunition was only operated in terms of some cutting technology, including cut method, cutting technique parameter, cutting operate. The chemical composition of the cutting ammunition is the key to the final incision quality. The powders include thermite, gas-making agents and alloying addition. KNO3 is up to 4.8% to 10.5% in the cutting medicament and CuO+Al is up to 13.6% to 22.8% in the thermite to cut steel of Q235 which is 263mm ×165mm × 20mm on the basis of the eject times of case primer, depth of the hole, diameter of the hole and the taper . |
