Description

Technical Field

[0001] The present invention relates to the technical field of vacuum consumable furnace cover cleaning, and specifically relates to a vacuum consumable furnace cover cleaning device and method. Background Art

[0002] The vacuum consumable furnace is a device used to smelt titanium alloys. Smelting titanium alloys involves a refining and purification process, but the raw materials for the titanium alloy electrodes themselves contain certain impurities. The splashes and volatiles generated during the smelting process can form impurities that adhere to the furnace cap of the vacuum consumable furnace. These impurities include hydrogen, oxygen, nitrogen, carbon, and other metallic elements, as well as the resulting oxides, hydrides, nitrides, and carbides. These impurities formed in the furnace cap require regular cleaning. If not cleaned for a long time or not cleaned thoroughly, there is a risk that these impurities will fall back into the lower furnace body during the smelting process, resulting in the final titanium alloy ingot not meeting the composition requirements, or forming low-density or high-density inclusions in the ingot, as well as other defects, ultimately causing the ingot to be scrapped or downgraded. The ingot is made of titanium alloy, an aerospace material with very high cost. The scrapping or downgrading of the ingot will result in significant losses for the company.

[0003] At present, the cleaning of the inner wall of the vacuum consumable furnace cap is done manually. During cleaning, the vacuum consumable furnace cap is shifted, and the vacuum consumable furnace cap is moved from the top of the lower furnace body to other positions. The vacuum consumable furnace cap is staggered with the lower furnace body, and then the furnace cap is controlled to be lifted and lowered to a suitable height. The vacuum consumable furnace cap is manually entered to use a scraper to clean the impurities on the inner wall of the vacuum consumable furnace cap. With this cleaning method, due to the large size of the vacuum consumable furnace, the manual cleaning intensity is high, the cleaning efficiency is low, and the quality of manual cleaning is uneven, which may cause local cleaning to be inadequate. In the prior art, there is also a method of cleaning the vertical inner wall of the furnace cover by mechanical means, but the cleaning is not fine enough, and the cleaning materials used during cleaning are excessively used, resulting in a waste of resources.
