Embodiment Construction

[0013] 1. In terms of equipment: such as figure 1 As shown, install an arc-shaped oil deflector 1 above the upper support roller; install an easy-to-disassemble oil deflector 3 at the bottom of the air roller cleaner 2; punch some holes of different shapes and sizes on the outlet guide 7, Add a deflector roller 4 between the outlet deflector roller 5, and leave a distance of 300-400 millimeters between the two deflector rollers, so that a vacuum blowing and sucking device (existing device) can be installed to remove part of the high-temperature oil mist suck away.

[0014] 2. In terms of technology: ① Improve the rolling line, and the rolling mill can increase the adjustment space of 0-20 mm, reducing the chance of contact between the aluminum plate and the rolling oil on the outlet guide plate; ② Properly adjust the vacuum blowing oil suction device to purge the plate surface according to the plate width The angle and distance of the air nozzle.

Abstract

The invention relates to an on-line baffling and removing oil method of a cold-rolled aluminum plate and strip. The method is characterized in that the invention comprises two aspects of equipment and technique; 1) equipment: an arc oil baffle plate is arranged above an upper supported roller and an oil deflector which is easy to be assembled and dismantled is arranged at the bottom of an air roller cleaner; an outlet guide plate is perforated and a tilted guide roller is arranged between a pair of scissors and an outlet tilted guide roller; 2) technique: (1) the rolling line is elevated and the adjusting space of a rolling mill can be elevated by 0 to 20 millimeters; (2) the angle and distance of the air blowtorch for sweeping the plate can be adjusted. By adopting the invention, oil falling from the memorial arch does not spatter on support rollers and flows into the air roller cleaner along an upper oil baffle plate; in addition, oil spattered by the upper support roller does not spatter on the memorial arch, which reduces the contact between an aluminum plate and the rolling oil on the outlet guide plate; therefore, the rolling oil on the plate can be cleaned by sweeping and oil spots can not be produced on the aluminum plate.

Description

technical field [0001] The invention relates to the technical field of aluminum processing, in particular to an online oil retaining and degreasing method for cold-rolled aluminum strips. Background technique [0002] Aluminum strip degreasing is a very complex technical problem, and it can also be said to be a common problem faced by the aluminum processing industry. The oil on the surface of the aluminum strip not only affects the quality of the product, but also affects the production cost and market image of the product. Composition of surface oil of aluminum strip: mainly rolling oil and additives, aluminum powder and alumina powder, mechanical oil and hydraulic oil mixed into rolling oil. The hazards of oil on the surface of aluminum strips: aluminum powder and alumina powder will form dirty oil spots on the surface of aluminum strips, which cannot be removed only through annealing process; mechanical oil and hydraulic oil mixed into rolling oil will cause the surfac...
