Description

Technical Field

[0001] The utility model belongs to the technical field of strip steel processing equipment, and in particular relates to a strip steel galvanizing tank. Background Art

[0002] Galvanizing is a critical process in strip steel production, enhancing its corrosion resistance. However, existing strip steel galvanizing tanks suffer from uneven heat distribution due to the uneven placement of heating elements, with some located at the bottom and others at the side. If the heating tubes are installed at the bottom, the zinc solution near the tubes heats first, leaving a temperature difference between the zinc solution further away from the tubes and the solution near the tubes. This temperature difference not only affects the galvanizing effect but also reduces the fluidity of the zinc solution. Utility Model Content

[0003] In order to overcome the problems existing in the background technology, the utility model provides a device capable of uniformly heating a galvanizing tank.

[0006] Furthermore, a fixing plate is provided at the bottom of the galvanizing tank body.

[0007] Furthermore, the fixed base plate is composed of two rectangular components, which increases the stability of the fixed plate.

[0008] Furthermore, there are four mounting brackets distributed in a rectangular shape, which is beneficial to the normal operation of the strip steel and improves work efficiency.

[0009] Furthermore, the stirrer is made of corrosion-resistant stainless steel.

[0010] Furthermore, the heating tubes are provided in plurality and are distributed diagonally in the agitator.

[0011] Furthermore, a thermal insulation layer is fixedly installed inside the inner wall of the galvanizing tank body.

[0012] The beneficial effects of the utility model are as follows: when the agitator in the utility model is working, the zinc liquid in the main body of the galvanizing tank can be fully mixed, and the flow of the zinc liquid can also be promoted; the agitator is provided with a heating pipe to uniformly heat the zinc liquid in the main body of the galvanizing tank and prevent local overheating, so that the viscosity of the zinc liquid can be kept as consistent as possible, thereby improving the fluidity of the zinc liquid and further making the galvanized layer on the surface of the strip uniform.
