Description

Technical Field

[0001] The utility model relates to the technical field of tinplate production, in particular to an annealing device for tinplate production. Background Art

[0002] Tinplate, commonly known as tinplate, refers to a cold-rolled thin steel plate with a thin layer of metal tin on the surface. It has certain strength and hardness, good formability and easy welding. The tin layer is non-toxic and tasteless, and the surface is bright. Tin mainly prevents corrosion and rust. According to the production process, it is divided into hot-dip tinplate and electroplated tinplate. Tinplate needs to be annealed during production. Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. Traditional tinplate mostly uses furnace cooling during the annealing process. Furnace cooling requires a long time to wait. For production and processing, this annealing cooling method is less efficient.

[0003] Chinese patent CN221094205U discloses a tin-plated steel plate annealing and cooling device, including a roller conveyor, a heating furnace, a cooling furnace and an air cooling furnace. The heating furnace is fixedly installed at one end of the top of the roller conveyor, the cooling furnace is installed in the middle of the top of the roller conveyor, and the air cooling furnace is fixedly installed at the other end of the top of the roller conveyor. A control panel is fixedly installed on one side of the roller conveyor. Through the heating furnace, the cooling furnace and the air cooling furnace, the heating rod generates heat radiation after being energized to heat the tin-plated steel plate. The tin-plated steel plate is then transported to a cooling furnace, where a steam nozzle sprays steam onto the surface of the heated tin-plated steel plate to cool it down, thereby accelerating the cooling rate of the tin-plated steel plate. The steam-cooled tin-plated steel plate is then transported to an air-cooling furnace, where the rotation of a cooling fan drives external air into the air-cooling furnace from the vents, and the surface of the tin-plated steel plate is cooled down by cold air. This continuous annealing cooling method improves production and processing efficiency, but is inconvenient to adjust the cooling temperature, and the tin-plated steel plate has a high heat content, which makes transportation more troublesome.
