Melt Casting Process of TNT-Based Explosives

In this article charging of explosives through casting has been investigated. Melt casting of TNT-based explosives is one of the most common techniques to economic and mass production of explosives. TNT is the only molten explosive at low temperature (80.4 C), so it is a convenient matrix for casting. Shrinkage of TNT in amount of 11-12% during solidification causes some problems in melt casting. In this article a description of different aspects of melt casting including material, common formulations, Meisner process, numerical simulation and comparison of advantages and disadvantages have been discussed. Studies show that the melt casting is a simple and feasible technique which can be safely used at industrial scale.
