A kind of gun alloy copper remover and preparation method

Abstract

The invention belongs to the technical field of alloy copper-removing agents, and in particular relates to a novel alloy copper-removing agent for guns and a preparation method. The invention heats the prepared lead, indium and bismuth metals, fully stirs and mixes them, and then keeps them warm; after natural cooling, repeats the heating three times to ensure that the metals are fully mixed; the cooled metal alloy block is made into powder by rotating electrode atomization method , which is the alloy copper removal agent. In the present invention, by adding three alloys of indium, lead and bismuth, when the projectile is launched, under the action of high temperature and high pressure of the propellant gas, the alloy melts and reacts with the residual copper in the barrel to form an intermetallic compound, and then under the action of the propellant gas, the residual copper is to remove.

Description

technical field [0001] The invention belongs to the technical field of alloy copper-removing agents, and in particular relates to an alloy copper-removing agent for guns and a preparation method. Background technique [0002] The barrel is one of the basic parts of a weapon, and its main function is to give the bullet a certain initial velocity and shooting direction. Since the 1860s, the appearance of rifled barrels has been a major revolution in the history of gun technology. Rifling can make the projectile rotate, so that the accuracy of the gun can be greatly improved. When firing, the high-temperature and high-pressure propellant gas produced by the propellant flows through the barrel at high speed, and dissipates heat to the bore wall in the form of convective heat release and radiation heat release; when the bullet is squeezed into the rifling, it will deform and generate heat. Therefore, the copper on the warhead will be deposited on the surface of the inner bore, ...

Problems solved by technology

[0006] Although the continuous development of copper removal wiper can improve the current copper removal effect, but the manual wiping mode is mostly used in the gun bore wiping method, which has problems such as high labor intensity and low wiping efficiency.

There are also many people who have developed automatic artillery wiping equipment to replace the manual wiping mode, but the volume, weight, function settings and operation of the equipment cannot be carried and operated by an individual soldier, and it cannot be used in light weapons due to its size.
