Abstract

This application relates to the technical field of automatic rifle regulators, and specifically discloses a novel carbide-reinforced cobalt-based superalloy regulator and its preparation method. The preparation method specifically includes the following steps: casting of consumable electrodes: consumable electricity The smelting of the electrode; the electroslag remelting continuous directional solidification mold is used to melt the consumable electrode to obtain an ingot; the ingot homogenization heat treatment: the homogenization heat treatment temperature is 1150‑1220 °C, and the homogenization heat treatment time is 10‑ 24h; preparation of forging billet: forging and opening the heat-treated ingot to prepare forging billet; rolling of bar: rolling the forging billet into bar; heat treatment of bar: heat treatment temperature is 1150-1220°C , the heat treatment time is 0.5-2h; regulator processing; and the regulator prepared by the above preparation method. The firing life of the regulator prepared by the preparation method of the present application is significantly improved.

Description

technical field [0001] The application relates to the technical field of automatic rifle regulators, more specifically, it relates to a novel carbide-strengthened cobalt-based superalloy regulator and a preparation method thereof. Background technique [0002] In the related art, most small and medium-caliber weapons are automatic rifles, and the common ways for automatic rifles to realize automatic include recoil type and air-guided type. Among them, the automatic method of the gas-guided type is to push the piston by shunting part of the powder gas, thereby realizing automaticity. The gas-conducting automatic rifle is provided with a regulator, which is used to regulate the amount of gas flowing out, and the regulator is provided with a regulating hole for the passage of gunpowder gas. [0003] During the use of automatic rifles, the adjustment hole on the regulator will not only be washed by high temperature, high pressure and high speed brought by the gunpowder combusti...
