Abstract
A transportable explosion chamber and method of operation for containing, controlling and suppressing explosive detonations, including the explosion surface hardening of impact-hardenable rail components. The apparatus comprises an elongate cylindrical steel containment vessel having an access door for introducing workpieces and a vent door for discharging explosion products. Both doors extend convexly into the vessel to facilitate the dissipation of explosion shock waves. Orificed vent pipes penetrate the vessel walls to controllably release explosion products into one or more exhaust manifolds. The vessel is surrounded and enclosed by steel skins supported by spaced octagonal steel support ribs fabricated by welding from interlocking elements. The hollows formed between the containment vessel and steel skins are filled with granular shock-damping silica sand which is introduced through filler openings at the top of the apparatus. To lighten the apparatus for transport, the shock-damping material may be drained through dump valves beneath the apparatus.
