Description
Technical field
This utility model relates to Equipment for Heating Processing field, in particular to a kind of sinking type annealing furnace.
Background technology
Annealing is a kind of metal heating processing technology, refers to METAL HEATING PROCESS to uniform temperature, keeps enough time, then cools down with Reasonable Speed, thus reduce the purpose of metal hardness.When aluminium conductor is made annealing treatment, it is generally required to aluminium conductor is wrapped on leer pan, aluminium conductor is being put in annealing furnace together with leer pan, make annealing treatment, in annealing process, the aluminium conductor being wrapped in outer ring is heated comparatively fast, and the aluminium conductor being wrapped in outer ring is heated slower, after having made annealing treatment, inner ring aluminium conductor and outer ring aluminium conductor hardness there will be difference.Identical with the hardness of outer ring aluminium conductor to make inner ring aluminium conductor, then need to increase heat time heating time, thus reduce work efficiency.
Utility model content
The purpose of this utility model is to provide a kind of sinking type annealing furnace, to improve the problems referred to above.
This utility model is achieved in that
