Description

Technical Field

[0001] This utility model relates to the technical field of hot-dip galvanizing of aluminum and magnesium strips, and in particular to a water quenching device for a new type of strip galvanizing production line. Background Technology

[0002] In the field of metallurgical technology, the requirements for steel corrosion protection are becoming increasingly stringent, and strip steel coating technology is constantly being improved. The coating has been changed from the original zinc plating to a zinc-aluminum-magnesium coating with higher corrosion resistance. In modern continuous hot-dip galvanizing production lines for strip steel, the water quenching device plays a crucial role in cooling the strip steel after air cooling. In the original units, the water quenching device used a double-sided water spray system, spraying water on the strip steel before it entered the water tank. This resulted in inconsistent cooling rates on the strip steel surface, causing longitudinal color differences in the zinc-aluminum-magnesium coating and affecting the surface uniformity and consistency of the strip steel. Utility Model Content

[0003] This utility model aims to address the shortcomings of existing technologies by providing a novel water quenching device for a strip steel galvanizing production line.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] The new strip galvanizing production line water quenching device includes a water quenching tank with two strip water quenching guide rollers installed inside. A bracket is installed on one side of the water quenching tank, and a strip feeding guide roller is installed on the bracket. A strip discharge platform is connected to the other side of the water quenching tank, and a water spraying device is installed on the strip discharge platform.

[0006] Each strip steel water quenching guide roller in the water quenching tank is provided with a fixed seat, and the strip steel water quenching guide roller is rotatably mounted on the fixed seat via a rotating shaft.

[0007] The bracket is equipped with a feeding guide roller mounting seat, and the strip steel water-quenched guide roller is rotatably mounted on the feeding guide roller mounting seat via a rotating shaft.

[0008] The water spraying device includes several spray heads arranged alternately on both sides of the strip steel, and the spray heads are connected to the main water spraying pipe through branch spray pipes.

[0009] The beneficial effects of this utility model are: This utility model adopts a three-roller structure, which uses the strip steel feeding guide roller to guide the strip steel into the water quenching tank, ensuring that the strip steel entering the water quenching tank is cooled evenly, thereby making the strip steel surface free of color difference, which facilitates the subsequent processing of the strip steel and improves the surface quality of the strip steel.
