Description

Technical Field

[0001] The utility model relates to the technical field of pouring molten metal, in particular to a high-temperature resistant magnesium smelting casting funnel device. Background Art

[0002] Magnesium and its alloys have significant advantages such as low specific gravity, high specific strength and specific stiffness, and low raw material prices. The research and application of magnesium alloys are increasingly valued by the material science and industry. With the increasing awareness of environmental protection and the requirement of energy conservation, the development trend of the automobile industry is to make automobiles lighter. While ensuring the original functional requirements of the automobile, light alloy (aluminum alloy and magnesium alloy) parts are used as much as possible to replace the steel parts used in large quantities in the automobile. In this case, magnesium alloys are increasingly becoming the preferred alternative material for steel parts.

[0003] When casting existing magnesium alloy castings, multiple people are required to cooperate in the casting, one person holds the funnel, one person controls the plug, and one person passes the protective gas during the pouring process. Since the hand-held parts will cause a certain amount of shaking, it is difficult to ensure the movement range of the plug. When the plug is higher than the magnesium liquid level, oxide slag will enter the mold cavity, reducing the quality of the casting. In addition, the funnel used in the pouring process has poor ability to resist high temperatures and low hardness. After long-term use, the internal wear and erosion of the funnel are serious, affecting the service life of the funnel. In addition, the existing funnels are fixed on the support frame, which is very inconvenient to replace. Utility Model Content
