초록 ▼

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.

[ We claim:] [1.] A combination of an 8-gauge or larger shotgun shell and an industrial ballistic tool having a rifled portion, comprising:a metallic base cup having a primer disposed therein;a cylindrical plastic tube having one end bonded to said metallic cup and an opposing end, the combination of said metallic cup and said plastic tube defining a cavity;a ballistic charge disposed within said cavity in communication with said primer;a zinc or zinc alloy projectile, a cylindrical, smooth surface, rear portion of which is encased in said cylindrical plastic tube and in direct contact with said cylindrical plastic tube, having a weight of from about 3 ounces to in excess of 3 ounces that is sufficiently soft to engage rifling extending from said rifled portion and thereby impart said metallic slug with spin stabilization, said zinc or zinc alloy projectile having symmetry about a longitudinal axis and having said cylindrical rear portion with a first substantially constant radial circular cross-sectional area of a diameter effective to engage said rifling, a cylindrical, smooth surface, mid-portion with a second substantially constant radial circular cross-sectional area that is less than said first substantially constant radial circular cross-sectional area and a tapered forward portion with a forwardly decreasing radial circular cross sectional area, a cross-sectional area discontinuity being disposed between said cylindrical rear portion and said cylindrical mid-portion and aligned with an open end of said plastic tube, wherein a center of gravity of said zinc or zinc alloy projectile is rearward of said cross-sectional area discontinuity;a cushioning material disposed between said rear portion and said ballistic charge; anda crimp extending from said open end of said plastic tube about said cross-sectional area discontinuity thereby sealing said zinc or zinc alloy projectile in said shotgun shell.
