A Research on Technology for Manufacturing Body Shell of Anti-Tank Rocket

Abstract

Body shell of anti-tank rocket which is a pipe part working under extreme conditions of high pressure and temperature, is manufactured from low-alloyed high quality steel 30X3MФ. The steel 30X3MΦ made in Vietnam appropriates of standard to produce body shell anti-tank rocket. The shell ensure technical requirements of composition, with very low rate of P, S and has good mechanical properties. After casting, steel billets were backward extrusion, includes 3 steps of thinned stamp, heat treatment and drawing processes, body shell fabrication is satisfied requirment of technique for anti-tank rocket shell. Results of fire testing of the body shells are in agreement with that of Russian ammunition. The body shells of anti-tank rocket which were manufactured in Vietnam conditions, satisfied desired technical requirement.
