Description

Technical Field

[0001] The invention relates to the technical field of alloy casting equipment, in particular to a high-temperature alloy casting device and method. Background Art

[0002] High-temperature alloy casting is a casting technology for manufacturing high-temperature alloy materials, which is mainly used to produce high-temperature parts in the fields of aerospace, turbines, petrochemical equipment, etc. This material has the characteristics of high strength, high hardness, good wear resistance, corrosion resistance and thermal stability, and can maintain its performance unchanged under high temperature environment. In the high-temperature alloy casting process, the commonly used materials are nickel-based high-temperature alloys, cobalt-based high-temperature alloys and iron-based high-temperature alloys. These materials all have good high-temperature properties, but their chemical composition and physical properties are also different. For example, nickel-based high-temperature alloys are mainly composed of nickel, chromium, molybdenum, tungsten and other elements, and have good oxidation resistance and thermal stability; cobalt-based high-temperature alloys are mainly composed of nickel, chromium, tungsten, molybdenum and other elements, and have good high-temperature strength and oxidation resistance; iron-based high-temperature alloys are mainly composed of iron, chromium, nickel, molybdenum and other elements, and have good wear resistance and corrosion resistance.

[0003] High-temperature alloy casting devices play an important role in modern manufacturing, especially in the fields of aerospace, power engineering, etc. However, there are some significant problems in the use of existing high-temperature alloy casting devices, which seriously affect the work efficiency and stability of the equipment. First, demolding difficulty is a common problem. During the casting process, the adhesion between the mold and the casting is strong, which makes demolding extremely difficult after the casting cools. This not only increases the complexity of manual operation, but also may cause damage to the casting and affect the quality of the product. In addition, frequent demolding problems extend the production cycle, reduce the overall production efficiency, and thus affect the economic benefits of the enterprise. Secondly, the current high-temperature alloy casting device has poor stability and is prone to failure during long-term use. High-temperature alloys require a high temperature and high pressure environment during the casting process, and may be deformed, cracked or otherwise damaged after long-term use. In addition, the maintenance cost of the equipment also increases. Due to frequent failures and demolding difficulties, the equipment needs to be regularly maintained and parts replaced, which invisibly increases the operating costs of the enterprise and reduces the overall production efficiency.
