Description

Technical Field

[0001] This utility model relates to the field of galvanizing furnace technology, and more specifically, to a galvanizing furnace for galvanizing. Background Technology

[0002] The galvanizing furnace is an improvement on the structure of the iron pot galvanizing furnace. Galvanizing, also known as hot-dip zinc plating, is an effective method of metal corrosion protection. It is mainly used on metal structures in various industries. After rust removal, steel parts are suspended by hooks and immersed in high-temperature zinc liquid, so that a zinc layer is attached to the surface of the steel parts, thereby achieving the purpose of corrosion protection. Galvanizing furnace is required in the above operation.

[0003] However, traditional galvanizing furnaces do not have the function of adjusting the immersion depth of metal parts, which makes them unsuitable for galvanizing steel parts of different sizes, resulting in incomplete immersion.

[0004] Furthermore, the galvanizing process of steel parts can easily generate some high-temperature fumes, which, if discharged directly, will have a certain impact on the surrounding environment. Utility Model Content
