Abstract

The invention relates to the technical field of automatic rifle regulators, and particularly discloses a novel carbide-reinforced cobalt-based superalloy regulator and a preparation method thereof. The preparation method specifically comprises the following steps: casting of a consumable electrode; smelting of the consumable electrode, specifically, smelting the consumable electrode by using an electroslag remelting continuous directional solidification crystallizer to obtain a cast ingot; homogenization heat treatment of the cast ingot, wherein the homogenization heat treatment temperature is 1150-1220 DEG C, and the homogenization heat treatment time is 10-24 hours; preparation of forging stock, specifically, carrying out forging cogging on the cast ingot subjected to heat treatment to prepare the forging stock; rolling of a bar: specifically rolling the forging stock into the bar; heat treatment of the bar, wherein the heat treatment temperature is 1150-1220 DEG C, and the heat treatment time is 0.5-2 hours; and processing of the regulator; The invention also provides the regulator prepared by the preparation method. The shooting life of the regulator prepared through the preparation method is remarkably prolonged.

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...
