The present utility model relates to the technical field of extruder accessories, and discloses a nickel‑based tungsten carbide alloy twin‑screw extruder barrel structure, comprising an extruder. A detachable barrel is mounted on one side of the extruder, and a plurality of detection components matching the internal shape of the barrel for crack detection of the inner wall of the barrel are arranged inside the barrel. By arranging detection components, collection components and moving components, during extruder production, the moving components are first used to place the detection components into the barrel to detect whether there are cracks on the inner wall. During detection, the collection components can also be used to collect impurities scraped by the detection components. Such detection is not only fast and frequent, but also can clean the inside of the barrel, prevent impurities from adhering to and corroding the inner wall of the barrel, and prolong the service life of the barrel.
