Embodiment 1

[0042] The size of the incoming material is 7μm*1000㎜, 3 tons of rolls. The inspection shows that there is oil visible to the naked eye on both sides, and the width of the residual oil area is about 20cm. The slit products belong to users with high requirements for degreasing quality. Before starting the machine, set the surface temperature of the guide roller to 60°C, the uncoiling speed to 300m / min, and the outlet temperature of the tuyere to about 40°C. After hot air blowing, the oily areas on both sides are reduced to within 3cm, and the oily traces are also significantly reduced. The total annealing time is set to 75h, which is 25h less than the original process. Inspection after release from the furnace: the water brushing test is A-level, which is equivalent to the original process, and there is no obvious difference. There is no abnormality in the 3cm residual area visible to the naked eye after treatment. The situation is normal compared with the original process.

Embodiment 2

[0044] The incoming material specification is 9μm*960㎜ roll 2.5 tons, the inspection shows that the entire foil surface has oil visible to the naked eye, and the slit products belong to users with high requirements for degreasing quality. Before starting the machine, set the surface temperature of the heat guide roller to 55°C, the air outlet temperature of the tuyere to about 40°C, and the uncoiling speed to 350m / min. After hot air blowing, the size of the residual oil on the entire foil surface is reduced to 2-3cm sporadic dots, and the traces of oil are significantly reduced. The total annealing time is set to 70h, 20h less than the original process. Inspection after release from the furnace: the water brushing test is grade A, which is equivalent to the original process. There is no oil spot on the entire annealed aluminum foil surface.

Embodiment 3

[0046] The incoming material size is 6.3μm*880㎜, roll 3.5 tons, this specification is produced for Tetra Pak users, it is a large roll diameter product, the user has higher requirements for degreasing and surface roughening. The inspection shows that there is oil visible to the naked eye on one side of the foil surface, and the slit products belong to users with higher requirements for degreasing quality. Before starting the machine, set the surface temperature of the thermal guide roller to 60°C, the outlet air temperature to about 45°C, and the uncoiling speed to 380m / min. After hot air blowing, the residual oil on the foil surface becomes 2-3cm sporadic spots, and the traces of oil are significantly reduced. The total annealing time is set to 80h, 15h less than the original process. Out of the furnace inspection: the water spray test is grade A, and there is no obvious difference in the degreasing effect from the original process, and no oil spots that have not been degrea...

Abstract

The invention belongs to the technical field of nonferrous metallurgy processing and relates to an aluminum foil surface residual oil pretreatment device used in the aluminum foil slitting or finishing process, in particular to an aluminum foil surface residual oil pretreatment temperature control purging device and a use method and application thereof. The aluminum foil surface residual oil pretreatment temperature control purging device is composed of an electric heating guide roller (1), a cross beam (2), a tuyere (3), an intelligent temperature controller and a compressed air source. The electric heating guide roller (1) and the cross beam (2) are parallel in the axial direction and are fixed by a support, the tuyere (3) is fixed on the cross beam (2), the intelligent temperature controller is used for controlling temperature of the electric heating guide roller (1), compressed air in the compressed air source is guided into the electric heating guide roller (1) to be heated, and the heated compressed air serves as working media of the tuyere (3). The use method and application of the aluminum foil surface residual oil pretreatment temperature control purging device are further disclosed. The aluminum foil surface residual oil pretreatment temperature control purging device and the use method and application thereof have obvious effects in shortening aluminum foil annealing cycle and reducing oxidization and annealing soft bar happening.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metallurgical processing, and relates to a device for pretreating residual oil on the surface of aluminum foil in the aluminum foil cutting or finishing process, in particular to a temperature-controlled purging device for residual oil on the surface of aluminum foil and its use method and uses. Background technique [0002] Aluminum foil generally refers to rolled aluminum products with a thickness of less than 0.2mm and a rectangular and uniform cross-section, especially double-zero foil, which is mainly used in cigarettes, food, medicine, electronics and other industries due to its properties of shading, freshness, and anticorrosion. Lining material, when used, is compounded with other packaging materials such as plastic, paper, etc. to enhance the strength of the packaging material. Aluminum foil is required to have good formability, continuity and a bright and clean surface during use, ...
