Manufacturing device for aluminum alloy castings

Abstract

The invention relates to the technical field of manufacturing of aluminum alloy castings, in particular to a manufacturing device for aluminum alloy castings. The manufacturing device comprises a casting mold, wherein an aluminum alloy smelting furnace is fixedly arranged at the upper side of the casting mold; a high-temperature heating furnace is arranged in an opening of the aluminum alloy smelting furnace; the high-temperature heating furnace is fixedly connected to the inner wall of the aluminum alloy smelting furnace through fixed rods which are uniformly arranged at the periphery; the upper end of a rotary rod is coaxially and fixedly connected to the output end of a drive motor; an inner barrel body is vertically arranged in the high-temperature heating furnace; the inner barrel body sleeves the rotary rod; the upper end of the inner barrel body penetrates through the high-temperature heating furnace and extends to the outside; an extruding assembly is arranged in the inner barrel body; a ring-shaped shell sleeves the high-temperature heating furnace; a plurality of communication tubes are arranged at the upper side of the ring-shaped shell in a surrounding mode; and a crushing extruding assembly is arranged in the ring-shaped shell. The manufacturing device adds a heating stroke of a refining agent without high-temperature preheating, guarantees sufficiently small particles of the refining agent through actions of extruding, cutting and grinding, and extrudes until molten aluminum alloy is stirred more sufficiently.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy casting preparation, in particular to an aluminum alloy casting preparation device. Background technique [0002] Aluminum alloys are widely used in aviation, aerospace, automobile, shipbuilding and other industrial fields. At present, aluminum alloys are often produced by casting. During casting, the refiner is used to control the refinement structure of the cast alloy and affect the forging billet structure. Al-Ti-B master alloy is one of the most important refining agents for refining the aluminum alloy structure. The Al-Ti-B refining agent mainly plays a role in refining TiAl3 and TiB2 particles. At present, its mechanism of action is not very clear, mainly Its shape, size and content affect the refinement effect. There are clear restrictions on the size of TiAl3 and TiB2 particles in the AlTiB refiner in international standards. The smaller the particles, the more obvious the refinem...

Problems solved by technology

[0005] It needs to be preheated at high temperature, and then extruded through high temperature reaction to form a filamentous refiner, and finally the refiner is introduced into the aluminum alloy melt by cutting and high-pressure injection, the efficiency is low, and the size of the refiner is still relatively small.
