Description

Technical Field

[0001] The utility model relates to the technical field of lubricant spraying devices, in particular to a lubricant spraying device for cold rolling of steel plates. Background Art

[0002] As we all know, cold-rolled steel strip is made of hot-rolled coils and rolled at room temperature below the recrystallization temperature. It includes plates and coils, and can be produced by many domestic steel mills such as Baosteel, Wuhan Iron and Steel, Anshan Iron and Steel, etc. Among them, the ones delivered in sheets are called steel plates, also called box plates or flat plates; the ones delivered in long lengths and in coils are called steel strips, also called coils.

[0003] After searching, application number 202122113785.1 discloses a lubricant spraying device for cold rolling of steel strip, including a base, the top of the base is connected to a top plate through a plurality of support columns, an electric push rod is installed on the top plate, the output end of the electric push rod passes through the top plate and is connected to a mounting plate, two first fixed blocks are connected to the bottom end of the mounting plate, an upper extrusion roller is rotatably connected between the two first fixed blocks, two second fixed blocks are fixedly connected to the top of the base, a lower extrusion roller is rotatably connected between the two second fixed blocks, and the top of the base is connected to a storage barrel through a pad.

[0004] During use, a lubricant spraying device for cold rolling of steel strips in this patent application uses an air pump to inflate the storage barrel, forcing the pressure inside the storage barrel to increase. The lubricant in the storage barrel is discharged through the spray head on the conveying pipe under the action of pressure, thereby spraying the lubricant. However, during such use, since the spraying length formed by the equipment through the conveying pipe and the spray head is fixed and cannot be adjusted accordingly with the width of the steel strip, when the width of the steel strip is much smaller than the spraying length of the equipment, a part of the sprayed lubricant will not act on the steel strip, thereby reducing the utilization rate of the lubricant of the equipment and causing waste of lubricant. For this reason, we propose a lubricant spraying device for cold rolling of steel plates. Utility Model Content
