Description

Technical Field

[0001] This utility model relates to the field of anti-gravity casting technology, and in particular to a device that avoids damage to ceramic riser pipes and their surface coatings during the transfer process, and can improve the transfer efficiency of ceramic riser pipes and improve the working environment of workers. Background Technology

[0002] Currently, high-temperature alloy anti-gravity investment casting is the preferred casting technology for complex thin-walled hot-end castings in high-end equipment such as aerospace engines, ships, and gas turbine generators in my country. The riser pipe, as the channel for the high-temperature alloy molten metal to fill and feed from bottom to top, is a key component for temperature and pressure resistance. The filling temperature of the high-temperature alloy molten metal is above 1400℃ and contains various toxic elements such as Al and Ti. Therefore, high-temperature alloy anti-gravity casting riser pipes are generally made of ceramic materials, and their surface requires a protective coating. Ceramic riser pipes and their surface coatings are prone to damage during transportation and assembly. This can lead to molten metal contamination and casting scrap, or even high-temperature molten metal splashing, endangering equipment and lives. When using ceramic riser pipes, they need to be preheated to above 800℃ before being transferred from the preheating furnace to the middle partition for assembly. According to existing technology, this process is mainly completed by workers wearing heat-insulating clothing using iron pliers. There are problems such as the iron pliers easily damaging the riser pipe and its surface coating; and the ceramic riser pipe tilting during assembly, causing the outer wall coating to scrape against the assembly hole.

[0003] Therefore, how to avoid damage to ceramic riser pipes and their surface coatings during the transfer process, and how to improve the transfer efficiency of ceramic riser pipes and improve the working environment of workers are urgent problems that the industry needs to solve.
