Description

Technical Field

[0001] The utility model relates to the technical field of casting manufacturing, in particular to a self-scraping slag trolley for an annealing furnace. Background Art

[0002] In the process of metal casting manufacturing, annealing furnace is an indispensable and important equipment used to heat metal materials to change their physical and chemical properties, such as removing stress, improving structure, and increasing toughness.

[0003] The trolley of the annealing furnace is responsible for the transportation of castings. When in use, the trolley is loaded outside the furnace, and the castings to be annealed are placed on the trolley. The trolley then enters the annealing furnace for heating. After annealing, it is moved out of the furnace to unload. Since metal castings will produce oxides during the annealing process, these oxides will adhere to and contaminate the trolley placement surface, which requires regular cleaning. Existing cleaning methods are mostly done by manual handheld tools, which are highly dependent on manpower, have low cleaning efficiency and are prone to burns (the trolley may need to be used for the next batch of annealing operations as soon as possible after use, and the trolley is cleaned directly before cooling down).

[0004] Therefore, the utility model proposes a self-scraping trolley for an annealing furnace to solve the above problems. Utility Model Content
