ABSTRACT:
A projectile for an industrial ballistic tool is formed from zinc or a zinc based alloy. The projectile has symmetry about a longitudinal axis and a rear portion of the projectile engages rifling, either within the barrel of the industrial ballistic tool or in a rifled extension, imparting ballistic stability. The projectile is particularly suited for high temperature industrial applications, such as removal of "clinkers" from cement kilns or lime kilns or removal of a plug when tapping an electric arc furnace, as used in the manufacture of metallic alloys such as ferrosilicon. The vaporization temperature of the projectile is sufficiently low that after effecting removal of the clinker or plug, the projectile vaporizes and does not contaminate the kiln, furnace or end product such as lime, cement or metallic alloy.
